Answer:
x = -26, y = 68
Step-by-step explanation:
Hello!
We first have to isolate x or y in one of the equations
5x + 2y = 6
Subtract 5x from both sides
2y = 6 - 5x
Divide both sides by 2
y = 3 - 5/2 x
Now we can put this into the other equation to solve for x
Expand the 3
8x + 9 - 15/2 x = -4
Combine like terms
1/2 x + 9 = -4
Subtract 9 from both sides
1/2x = -13
Multiply both sides by 2
x = -26
Now we can put this into either of the equations to find y
5(-26) + 2y = 6
Simplify
-130 + 2y = 6
Add 130 to both sides
2y = 136
Divide both sides by 2
y = 68
The answer is x = -26 and y = 68
Hope this helps!
Answer:
The first '?' is 14, the second '?' is 17
Step-by-step explanation:
1.
x + 7 = ?, x = 7
7 + 7 = 14
2.
x + 7 = ?, x = 10
10 + 7 = 17
If x=3 then the answer would b
2(3)+4= $10 So y= $10
Hope this helps!
1 meter - 100 cm
14 x 100 = 1400 cm per second
60 seconds per minute
1400 * 60 = 84,000 cm per minute
