So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3
Answer:

Answer:
4.17
Step-by-step explanation:
6000x = 25000
x = 25000 / 6000
x = 4.17
Answer:
55.25 degrees or 55 degrees
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
since both equations express y in terms of x we can equate the right sides
x + 7 = - 2x + 19 ( add 2x to both sides )
3x + 7 = 19 ( subtract 7 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations for y
y = x + 7 ⇒ y = 4 + 7 = 11
solution is (4, 11 )
