Answer:
D
Step-by-step explanation:
Given the 2 equations
4x + 8y = 21 → (1)
y = - x + 3 → (2)
Substitute y = - x + 3 into (1)
4x + 8(- x + 3 ) = 21 ← distribute parenthesis on left side
4x - 4x + 24 = 21 ( subtract 24 from both sides )
0 = - 3 ← not possible
This indicates the system has no solutions
If you divide 120,000 by 1,500 you will get the amount that it costs per square feet which you would then multiply by 2,400 to get 192,000. So the answer is $192,000
Answer:
5136
Step-by-step explanation:
2*10-4 = 20-4 = 16
3*107 = 321
16*321 = 5136
Answer:
<h2>x = 9</h2>
Step-by-step explanation:
<u>Cross multiply</u>
That's
7x = 3( 2x + 3)
Multiply the terms
That's
7x = 6x + 9
<u>Subtract 6x from both sides</u>
We have
7x - 6x = 6x - 6x + 9
Simplify
We have the final answer as
<h3>x = 9</h3>
Hope this helps you
