Need to do the 2^3 first
answer is A
Answer:
x = (19.5 - 6y - 6z) /6
y = (19.5 - 6x - 6z) /6
z = (19.5 - 6x - 6y) /6
Step-by-step explanation:
Let the Apples be X
Oranges be Y
Avocados be Z
Total cost of the Fruits = 19.5
So the equation would be as follows:
6x + 6y + 6z = 19.5
for Apples, equation would be:
6x= 19.5 - 6y - 6z
x = (19.5 - 6y - 6z) /6
For Oranges, the equation would be:
6y= 19.5 - 6x - 6z
y = (19.5 - 6x - 6z) /6
For Avocados, the equation would be:
6z= 19.5 - 6x - 6y
z = (19.5 - 6x - 6y) /6

Answer:
3x0.15=0.45
Step-by-step explanation:
<span>-3a+7b=-16
-9a+5b=16
multiply 1st equation by 3
</span><span>-9a + 21b = -48
-9a + 5b =16
------------------------subtract
16b = -64
b = - 4
</span>-3a+7b=-16
-3a+7(-4)=-16
-3a = -16 +28
-3a = 12
a = -4
answer
a. first choice
<span>The values of a and b are both equal to –4.</span>
