Answer:
a), b), e)
Step-by-step explanation:
<em>a) -30(3 + 2w) = -90 - 60w</em>
<em>b) (-9 − 6w) x 10 = -90 - 60w</em>
c) -3(30 - 20w) = -90 + 60w
d) (6 + 4w) × 15 = 90 + 60w
<em>e) −20(4.5 + 3w) = -90 - 60w</em>
Answer:
y = -x-3
x-y = -3
x - 2y = 10
Step-by-step explanation:
x − 3y = 6
Slope intercept form is y = mx +b
We need to solve for y
Subtract x from each side
x-x-3y = -x+6
-3y = -x +6
Divide each side by -3
-3y/-3 = -x/-3 +6/-3
y = 1/3 x -2
Standard form is Ax +By = C
y = -x-3
Add x to each side
x-y = -x+x-3
x-y = -3
y = 1/2x -5
We do not like fractions in standard form, so multiply by 2
2y = 2*1/2x -2*5
2y =x-10
Subtract x from each side
-x +2y = x-x-10
-x+2y = -10
We like to have the coefficient on x be positive
Multiply by -1
x - 2y = 10
The weight of wrestler was 80 kg before the special diet
Step-by-step explanation:
Given function is:
We can substitute the values of t to find the weight after t number of months
When we have to find the initial weight , t has to be put equal to zero
So,
Hence,
The weight of wrestler was 80 kg before the special diet

Answer:
x = 4
Step-by-step explanation:
Given that the triangle is equilateral then the measure of each angle is 60°
Equate 9x + 24 to 60 and solve for x
9x + 24 = 60 ( subtract 24 from each side )
9x = 36 ( divide both sides by 9 )
x = 4
