The answer is: 36 in total
Answer:
4Z+16-Z²
Step-by-step explanation:
Given that,
D = Z+6
C = -2 + Z - Z²
We need to find the value of 3D+C.
So,
3D+C = 3(Z + 6)+(-2 + Z - Z²)
= 3Z+18-2+Z-Z²
= 4Z+16-Z²
So, the required expression is 4Z+16-Z².
Answer:
Step-by-step explanation:
7-5
-21-0
-2/21. the y intercept would be 5, considering the x is 0 on the first pair of coordinates. so y=-2/21x+5, or A
#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190
2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80
#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80
#16
$57 + $28.50 ($57 * .50) = $85.50
0.578=289/500, 3.5= 3 1/2, 2.73= 2 73/100, 0.4211= 4211/10000. Hope this helps :)
