Answer:
Step-by-step explanation:
x + 3 y = 1 ----------------(I)
-3x - 3y = -15 -------------(II)
Add the equations and y will be eliminated and we can find the value of x
(I) x + 3y = 1
(II) <u>-3x -3y = - 15</u> {Now add}
-2x = - 14
x = -14/-2
x = 7
Plugin x =7 in equation (I)
7 + 3y = 1
3y = 1 - 7
3y = -6
y = -6/3
y = -2
Answer:
The answer is 32.
Step-by-step explanation:
Just multiply the height by the base length. 4*8=32
They made an error in step 2 which showed up in step 3. When adding those numbers, Dan should have gotten $223.45 and not $241.95
Answer:
a=54
Step-by-step explanation:
a/9 = 6
(mutliply both sides by 9)
9(a/9) = 6(9)
a = 54
