Answer:
Step-by-step explanation:
30 30 x 3 = 90
x 3
90
first multiply 4 x 5 = 20 bring down 0 then multiply 4 x 2 = 8 then add+2= 10
25 x 4 = 100
12 x 15 = 180
Answer:
24.75
Step-by-step explanation:
2x-11 + 6x-7 =180
8x-18=180
8x=198 /8
x=24.75
If you know the rugs sell for 8$ per square foot and the total spend was $432. You divide 432 by 8 to find the total number of square foot of the rug. Which is 54. To find total square foot you find the area. So the area of a rectangle is L*W. So 54 = 9*width. So just divide 54 by 9 and you get the width of the rug. The width is 6 foot. Now you check. A nine by 6 rugs square foot is 54. and then times by 8 and you get 432 total. So you know the rug is 6 foot wide. :)

Answer:
√89 or 9.43 units is the distance between Sophia's house and library
Step-by-step explanation:
H (1 ,1) ⇒ House
L(6 , 9) ⇒ Library
Leg₁ = OH = 6 - 1 = 5 units
Leg₂ = OL = 9 - 1 = 8 units
<h3> Pythagorean theorem;</h3>
Hypotenuse² = leg₁² + leg₂²
= 5² + 8²
= 25 + 64
= 89
hypotenuse = √89 units (radical form)
hypotenuse = 9.43 units
