Simplify by combining like terms
m - (2m + 5n - 3m)
Answer:
=2m−5n
Step-by-step explanation:
Let's simplify step-by-step.
m−(2m+5n−3m)
Distribute the Negative Sign:
=m+−1(2m+5n−3m)
=m+−1(2m)+−1(5n)+−1(−3m)
=m+−2m+−5n+3m
Combine Like Terms:
=m+−2m+−5n+3m
=(m+−2m+3m)+(−5n)
=2m+−5n

Step-by-step explanation:
Which of the following functions is represented by the statement, “A number is ten less than four times another number”? f ( x ) = − 4 x − 10 f ( x ) = − 4 x − 10 f ( x ) = 4 x − 4 f ( x ) = 4 x − 4 f ( x ) = 4 x − 10 f ( x ) = 4 x − 10 f ( x ) = − 10 x + 4
Answer:
f ( x ) = 4 x − 10
Step-by-step explanation:
The perimeter of a rectangular ink pad is 22 centimeters the area is 28 square centimeters
Answer
W=7
Explanation:
The formula for the perimeter for a rectangle is P = 2L + 2W
The formula for the area of a rectangle is A = LW
where L = length and W = width
P = 22 and A = 28
22 = 2L + 2W
28 = LW
Rewriting the 2nd equation L = 28/W
Substituting this into the first equation
22=2(28/W) + 2W
Reworking the equation to eliminate the denominator
22W = 2(28) + 2W2
22W = 56 + 2W2
and
2W2 - 22W + 56 = 0
Dividing by 2
W2 - 11W + 28 = 0
(W-7)(W-4)
Set each factor equal to 0 and solve each for 0
W = 4, W = 7
then W = 4

(2x-3) + (3x+6) = 73
Solve for x
2x - 3 + 3x +6 = 73
5x +3 = 73
5x = 70
x =14
Substitute x into the equations
2(x) - 3 = ?
3(x) + 6 = ?
3x - y = -1
-3x -y = 5
x = y =
Answer:
Step-by-step explanation:
Step 1: Solve3x-y=-1 for y
3x-y=-1
3x-y+-3x=-1+-3x (add -3x to both sides)
-y=-3x-1
-y/-1=-3x-1/-1 (divide both sides by -1)
y=3x+1
Step 2: 3x+1 for y in -3x-y=5
-3x-y=5
-3x-(3x+1)=5
-6x-1=5 (simplify both sides of the equation)
-6x-1+1=5+1 (add 1 to both sides)
-6x=6
-6x/-6=6/-6 (divide both sides by -6)
x=-1
Step 4: Substitute -1 for x in y=3x+1
y=3x+1
y=(3)(-1)+1
y=-2
ANSWER: x=-1, and y=-2

Simplify the following.
7^1=
4^0 =
6^-1 =
Answer:
1. = 7
2. = 1
3. = 0.16
Step-by-step explanation:
The square root of -72
'8.48528137 i' or 'unidentified'
-72 isn't actually possible because a positive number times a positive number is always a positive and a negative number times a negative number is always a positive number. So you could say "unidentified".
But in HiGh sChOoL you'll learn about imaginary numbers (according to my teachers), and how it works is; basically just find the square root of 72 and write 'i' after. 'I' stands for imaginary number.
Is this sequence arithmetic? -2.4,9.8,22,34.2...
Answer:
Yes
Step-by-step explanation:
9.8 - (-2.4) = 12.2
22 - 9.8 = 12.2
34.2 - 22 = 12.2
Since it increases by the same amount each time it is arithmetic
Which point could be removed in order to make the relation a function?
{(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)}
(8, 3)
(3, –6)
(–1, 8)
(–4, –2)
Answer:
(3, –6)
Step-by-step explanation:
A function is a relation where one input is assigned to exactly one output.
This means that no inputs must be repeated in the relation.
(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)
The input of '3' repeats in the relation.
By removing (3, -6), we can make the relation given a function.
Hope this helps.
Madison’s manicure cost $25.90. She wants to leave a 15% tip. Which of the following is closest to the amount of the tip she wants to leave?
A. $2.00
B. $3.00
C. $4.00
D. $5.00
Answer:
C) $4.00
Step-by-step explanation:
Here's how I did it:
So we're trying to find 15% of $25.90... we can say that the $25.90 is 100% of Madison's Manicure... 100% can also be written as 1.0... why? well if 1.0 is 100%, then we can say any other percentage is proportionate to this... for example... 0.25 is 25% of 1.0... In this case... we are trying to add an additional 15% to the 100% price of the manicure... (Remember... with our proportion we can say that 115% is the same as 1.15) If we take our proportion:
1.15 x 25.90 = 3.89
4.00 is the closest to 3.89
therefore the answer is C) $4.00
