Answer:
The value of y = 4.3
Step-by-step explanation:
It is given that,
5/7 = y/6
<u>To find the value of y</u>
We have, 5/7 = y/6
(5 * 6) = (y * 7)
y * 7 = 5 * 6
y = (5 * 6)/7
= 30/7
= 4.29
≈ 4.3
Therefore the correct answer, the value of y = 4.3
Answer:
x=-5, y=2. (-5, 2).
Step-by-step explanation:
2x+y=-8
3x-5y=-25
------------------
5(2x+y)=5(-8)
3x-5y=-25
-------------------
10x+5y=-40
3x-5y=-25
--------------------
13x=-65
x=-65/13
x=-5
2(-5)+y=-8
-10+y=-8
y=-8-(-10)=-8+10=2
Answer:
-20
Step-by-step explanation:
y = -3x+1
if the input is 7, it means x=7 so substitute in the equation
y= -3*7+1 = -21+1= -20 which is the output
Answer:
30
Step-by-step explanation:
Ok, So:
10x3=30-3=27
It Would Be 27
