Answer:
x = 2
Step-by-step explanation:
According to the second equation, y = x + 4. Substitute x + 4 for y in the first equation, obtaining:
x + 2(x + 4) = 14, or:
x + 2x + 8 = 14
Combining the x terms, we get:
3x + 8 = 14
Combining the constant terms, we get:
3x = 6
Therefore, x = 6/3 = 2
Step-by-step explanation:
3b=2/3
b=2/3÷3
b=2/3×1/3
b=2/9
Answer:
1
Step-by-step explanation:
V = pie x 7² x h
V = 3.14 ×7² x 10
V = 3.14 x 49 x 10
V = 3.14 x 490
V = 1538.6
If you add 2 it will make it 3077.2 and that goes over so 1
Hope this helps :)
