Answer:

<u>The answer is 1. 64 and 2. 60</u>

Step-by-step explanation:

Question 7. 75% of what number is 48?

Number = x

75%x = 48

3x/4 = 48 (75% = 3/4)

3x = 192 (Multiplying by 4 at both sides of the equation)

<u>x = 64</u> (Dividing by 3 at both sides of the equation)

<u>Part 75 Whole 48 Part 100 Whole 64</u>

Question 8. 120% of what number is 72?

Number = x

120%x = 72

12x/10 = 72 (120% = 12/10)

12x = 720 (Multiplying by 10 at both sides of the equation)

<u>x = 60</u> (Dividing by 12 at both sides of the equation)

<u>Part 120 Whole 72 Part 100 Whole 60</u>

the length of a rectangle is 7 cm more than its width and the area is 30 cm find the length, width and the perimeter
mariarad [96]

Answer:

Step-by-step explanation:

let width=x

length=x+7

x(x+7)=30

x²+7x-30=0

x²+10x-3x-30=0

x(x+10)-3(x+10)=0

(x+10)(x-3)=0

either x=-10 (rejected being negative)

or x=3

width=3 cm

length=3+7=10 cm

Perimeter=2(10+3)=2×13=26 cm
