Answer:
let the total cost of a rug be x
then
30% of x =75
30/100*x =75
3x=750
x=750/3 = 250
Marc owe = 250-75 =175
Step-by-step explanation:
bearing in mind that perpendicular lines have <u>negative reciprocal</u> slopes, let's find firstly the slope of AC.
so, we're really looking for the equation of a line whose slope is 1/5 and that passes through (3,3)
Area=side^2
area=6.25^2
area=39.0625 ft^2
6.25 has 3 sig figs
39.1 ft^2 is answer
Answer:
A. 1.2x = 78
B. x = 65
Step-by-step explanation:
Just informally, first:
x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.
120% of x = 78
Change 120% to a decimal by moving the decimal two places to the left. Multiply.
1.2x = 78
To solve, divide both sides by 1.2
x = 78/1.2
x = 65
It’s going to be -2 because the y intercept is when x=0.
