The equivalent expression is: -2x + 10. therefore the correct option is C.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
From the distributive property;
-2(x - 5)
Then, multiply -2 and -5
-2 * x = -2x
-2 * -5 = 10
because two negatives make a positive
Therefore the answer would be -2x+10.
Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.

An insurance company only pays for full replacement if a driver is in a
wreck and is traveling a speed not deemed to be reckless. A speed of 80
mph or greater is considered reckless. Mallory has an accident and has
filed an insurance claim. The insurance uses a standard constant of
proportionality of .05 and she has a stopping distance of 245 feet. Will her
insurance provide a full replacement of her car? Explain why or why not
and show all work.
Answer:
70 mph, Yes the insurance company Will provide a full replacement for her car.
Step-by-step explanation:
To get the equation lets use direct variation, and K for the constant, S for the speed, and D for the stopping distance. d=ks^2, find s, or the speed, which will get the equation s=√d/k. The speed s, is equal to the square root of the stopping distance divided by the constant. Next, lets plug in the numbers s=√245/.05. Then, we find the square root of each number, √245 = ~15.652, and √.05 ~.2236 s=15.652/.2236 then divide, which will equal s=70. 70<80, so the insurance company will provide a full replacement for her car.

Theoretically, the standard error of the mean decreases as the sample size increases measures the variability of the sample mean from sample to sample is never larger than the standard deviation of the population All of the Above
Answer: All of the above
Step-by-step explanation:
The formula for the standard error of the mean is:
σM =σ/√N
where,
σM = standard error of the mean
σ = standard deviation of sample
√N = square of sample size
As the sample size of a population rises, it should be noted that the standard error of the mean will decrease. This is due to the fact that when there's an increase in sample size, there'll be cluster of the sample mean around the population mean.
Also, the the standard error of the mean measures the variability of the sample mean from sample to sample and is never larger than the standard deviation of the population.
Therefore, the answer will be "all or the above".

Step-by-step explanation:
Dorian and Jack decided to go bowling. They each need to rent shoes and 1 lane, and Jack is a member.If Jack pays for both of them with $20, what change should he receive?
Answer:
$6.60
Step-by-step explanation:
This is an incomplete question. I have however searched for the concluding parts and same attached as seen below.
First, we need to calculate the costs for both shoes rented by Dorian and Jack.
Member's cost for each shoe rentage is $2.95 , and since both rents the shoe at same cost, therefore,
Cost = $2.95 + $2.95 + $7.50
Cost = $13.40
To get the balance that Jack should receive, we will simply deduct the cost from the initial $20 member cost, hence;
Balance = $20 - $13.40
Balance = $6.60.
Therefore, the change that should be received by Jack is $6.60

B. 85, 13 and 84
C. 37, 35 and 12
D. 24, 22 and 40
The Pythagoras theorem is not applicable in 24, 22, and 40 thus (D) will be not the side of the right angle triangle.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The Pythagoras theorem is given as,
Hyp² = base² + perp²
Since the hyp is the biggest side thus it can be said to be as,
Biggest side² = (smaller side 1)² + (smaller side 2)²
In the 24, 22 and 40,
40² ≠ 22² + 24² thus it will not right an angle triangle,
Hence "In 24, 22, and 40, the Pythagorean theorem is not applicable so it will be not a right angle triangle".

B. Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?
Answer:
GH¢60
Step-by-step explanation:
Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?
Let the Total amount of Alex money = 1
We are told that she has GH¢15 left,
Hence, we find the fraction of the money she has left
1 - (1/4 + 1/2)
1 - 3/4
= 1/4
The fraction of the amount she left = 1/4
Let x represent the total amount of money that Alex had
1/4 × x = GH¢15
x / 4 = GH¢15
Cross Multiply
x = 4 × GH¢15
x = GH¢60
Therefore, Alex had GH¢60 at first

Step-by-step explanation:
0.30 x 100 = 30
Answer:
100
Step-by-step explanation:
10% of 100= 10
20% of 100 = 20
so
30% of 100=30
or you can do this method:
Turn the percentage into a decimal30%= 0.3Then take the 30 divided by your decimal 0.3030/0.30=100So the answer is 100Suppose that the battery has a total current in a series connection of 12.0 Ω and the lamps resistances R₁, R₂ and R₃ are 6.0 Ω, 4.0 Ω and 2.0 Ω, respectively. Compute for (a) the total resistance in a series connection and (b) the voltage drops across each resistor.
Answer:
Step-by-step explanation:
Let the total current = 12A
If there are there lamps 6.0 Ω, 4.0 Ω and 2.0 Ω in series,
a) The total resistance in series connected circuit will be:
Rt = R₁+R₂+R₃
Rt = 6+4+2
Rt = 12Ω
b) According to ohm's law, the voltage drop is expressed as V = IR
I is the current in each lamps
Note that the same current flows in the resistors for series connection
R are the resistances
For the 6Ω, resistor
V = IR
V = 12(6)
V = 72V
The voltage drop across it is 72V
For the 4Ω, resistor
V = IR
V = 12(4)
V = 48V
The voltage drop across it is 48V
For the 2Ω, resistor
V = IR
V = 12(2)
V = 24V
The voltage drop across it is 24V

The lengths of the sides of a quadrilateral are 4 consecutive even integers. The perimeter of the quadrilateral is 36 inches. What is the length of the longest side?
Answer:
Length of longest side is 10.5 inches
Step-by-step explanation:
Let the shortest side of the quadrilateral be x inches
The length of the consecutive sides will be;
x , x + 1 , x + 2 and x + 3 inches
By adding all
together, we get the perimeter of the quadrilateral
so;
x + x + 1 + x + 2 + x + 3 = 36
4x + 6 = 36
4x = 36-6
4x = 30
x = 30/4
x = 7.5 inches
The longest side is x + 3 = 7.5 + 3 = 10.5 inches

Jadiel wants to take his buddies out for pizza. Each medium
pepperoni pizza costs $10, and he has only $23 in his pocket. How
much money would he have to borrow to order three medium
pepperoni pizzas?
Answer:
7$
Step-by-step explanation:
1) 3x10=30 so 30 is how much money he needs
2)30-23=7 so 7 is how much he needs to borrow
Answer:
$7
Step-by-step explanation:
The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.

The length of a rectangle is twice its width. The perimeter is 60 ft Find its area.
a) A=200 ft²
b) A= 10 ft²
c) A= 100 ft ²
Answer:
A=200 ft²
Step-by-step explanation:
let the Length be L and the Width be W
We know that Perimeter = Length + Length + Width + Width
or,
Perimeter = 2(L + W)
given that Perimeter = 60 ft,
60 = 2(L+W) (divide both sides by 2)
60/2 = (L+W)
L + W = 30 ---------------------eq 1
we are further given that the length is twice the width, or,
L = 2W ---------------------- eq 2
substituting eq2 into eq 1,
L + W = 30
(2W) + W = 30
3W = 30
W = 10 (substitute this into eq 2)
L = 2W
L = 2(10)
L = 20
Area = Length x Width
= 20 x 10
= 200 ft²
