Answer:
15/100x 40= 6
Step-by-step explanation:
-2(x+7)+3=19
-2x-14+3=19
-2x-11=19
-2x=8
x=4
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
Answer:
C≈61.89
C=3830.37
Step-by-step explanation:
A≈615.75
You will need 27 quarters.
1.25*3= 3.75
3.75+3= 6.75
There are 4 quarters in a dollar. 6 dollars = 24 quarters, plus 3 more quarters to equal the .75
