How many solutions are there to the equation below?
3x - 10(x+2) = 13 - 7x
O A. O
B. 1
O C. Infinitely many
Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Answer:
It would be 0
Step-by-step explanation:
because its -7x+20=13-7x which in the end would 20=13

1. If you are having a cookout for 200 people and ribeyes are $200.00 per loin and you can get 50 ribeyes per
loin, how much will the steak cost? How much is the steak per person?
Answer:
$800 total paid for four loins. Everyone gets one ribeye so price of steak per person is four dollars.
Step-by-step explanation:
1 ribeye per person -> 50 ribeyes per loin -> 200 (people going)/50 (people fed per loin) = 4 (loins needed) -> $200.00 x 4 loins = $800 of loin total and 4 dollars per ribeye (1 ribeye per person)
wriye each expression with fewer terms.Show your work or explain your reasoning 10x-2x 10x-3y+2x
Answer:
20x-3y
Step-by-step explanation:
combine the like terms
so first do 10x-2x=8x
then you're gonna add from the line the 10x and the 2x which is going to give you 20x
no finally you are left with one number with the y variable, that is 3y.
Therefore your answer is 20x-3y
An eagle 311 feet in the air spots its prey on the ground. The angle of depression to its prey is 15°. What is the distance between the eagle and its prey? Round to the nearest foot.
Which could be used to find the number n? “Four less than a number, n, is equal to fifteen.”
A, ,B C, Or D
Answer:
C (n - 15 = 4)
Step-by-step explanation:
This is the answer becuase it can be rewritten as:
n - 4 = 15 (by subtracting 4 from both sides and adding 15 to both sides);
this equation describes the "written" (verbal) equation.

5 divided by 2,165 equals?
answer:
1/433 (decimal: 0.002309)
step-by-step explanation:
5/2,165
= 1/433
to change 1/433 to decimal we'll divide the numerator by the denominator-
1÷433
=0.00230946882
so we're going to round to the ten-millionths place
5 or more raise the floor, 5 or less let it rest
4>5
so 0.002309
good luck :)
i hope this helps

Find the total number of unit cubes that fill the entire prism.
50 decreased by ??? is 40
options are
60% 80%
19% 40%
Answer:
19%
Step-by-step explanation:
40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10
50, percentage decreased by 19% (percent) of its value = 40.5
50, percentage decreased by 40% (percent) of its value = 30
Hence, the answer is 19%

The height in feet of the curved arch support for a bridge can be modeled by f(x) =
-0.0009x2 + 1.24x + 1.65. You are standing on a platform 2 feet above the maximum height ofthe arch. If you bungee from this point, and your bungee will stretch to 420 feet before retracting;are you safe to jump?
A) Yes you are totally safe!
B) No, you will hit the ground before your bungee retracts
SHow steps please!
Answer:
A) Yes you are totally safe
Step-by-step explanation:
The function that models the height of the curved arch in feet, f(x) = -0.0009·x² + 1.24·x + 1.65
The height of the platform = 2 feet + The maximum height of the arch
The amount of stretch of the bungee before retracting = 420 feet
The vertex of the parabola is the point x = (-b/2·a), from which we get;
At the maximum height of the arch, x = -1.24/(2 × -0.0009) = 6,200/9 = 688.[tex]\overline 8[/tex]
The maximum height of the arch = f(688.[tex]\overline 8[/tex]), therefore, we have;
f(688.[tex]\overline 8[/tex]) = -0.0009×(688.[tex]\overline 8[/tex])² + 1.24 × (688.[tex]\overline 8[/tex]) + 1.65 = 428.76[tex]\overline 1[/tex]
The maximum height of the arch = 428.76[tex]\overline 1[/tex] feet
The height of the platform above the ground = 2 ft. + 428.76[tex]\overline 1[/tex] ft. = 430.76[tex]\overline 1[/tex] ft.
Therefore;
The height of the platform above the ground = 430.76[tex]\overline 1[/tex] feet > The amount the bungee will stretch before retracting = 420 ft.
430.76[tex]\overline 1[/tex] ft, > 420 ft.
Therefore, the jumper is totally safe.
Find the volume of the prism shown.
Answer:
41.16 m³

Substitution
y=7x+3
Answer: x= 1/7 y + -3/7
Step-by-step explanation:
y=7x+3
Step 1: Flip the equation.
7x+3=y
Step 2: Add -3 to both sides.
7x+3+(−3)=y+(−3)
7x=y−3
Step 3: Divide both sides by 7.

Using a graphical method, solve the simultaneous equations x+y =4 and y=2x+1
Answer:
(1, 3)
Step-by-step explanation:
Given the expression
x+y = 4 ... 1
y = 2x+1 ....2
Substitute equation 2 into 1
x + (2x+1) = 4
3x + 1 = 4
3x = 4-1
x = 3/3
x = 1
Since y = 2x + 1
y = 2(1) + 1
y = 3
Hence the solution to the equation is (1,3). This means that the coordinate point on the graph where both lines intersect will be at (1, 3)
