Step-by-step explanation:
Hope this helps!
if not I am sorry
Solution:
Given Expression is 1/40* x = 1/8
Step : Define x in the Equation:
Step : Divide the Equation by 8
Step : Do cross multiplication
Step : Arrange it in particular form
____________________________
☞ 1/40x = 1/8
☞ x/40 = 1/8
☞ x = ⅛ × 40
☞ x = 5
.
Therefore, Answer is 5.
Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
There is only one solution
When you graph both equations, they intersect therefore the intersection point tells you there is one solution. If it was infinitely many solutions then it would be the same line. If it was no solution then the graph would show to parallel lines.
