Answer:
Let number of laps she walked be equal to L
L=$7
7L = $105 (equation)
OPTIONAL: If you want to find how may laps she walked, divide both sides by 7
L = 105/7 = 15
She walked 15 laps
Step-by-step explanation:
The correct question in the attached figure
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
the answer is
the ratio x:y is 25:18
Answer:
x = 1
Step-by-step explanation:
Set up the rational expression with the same denominator over the entire equation.
Since the expression on each side of the equation has the same denominator, the numerators must be equal
5x =4x+1
Move all terms containing x to the left side of the equation.

Answer:
y = 13x
Step-by-step explanation:
Substitute 2 in x and you'll get 26:
y = 13•2
y = 26
.45, because it's 45/100.
