#1. Step one) we set find what we can multiply by 5 to get 20, so we divide 20 by 5.
20/5 = 4
Step two) we multiply the bottom denominator (8) by 4
8x4=32
Step three) leave the top numerator the same (20) and replace (d) with 32
Answer : 20/32
#2 step one) we divide 14 by 7
14/7 = 2
Step two) divide 10 by 2
10/2=5
Step three) replace z with 5
Answer) 7/5
#3 step one) divide 24 by 8
24/8=3
Step two) divide 21 by 3
21/3 = 7
Step three) replace (x) for (7)
Answer) 7/8

Answer:
15.75 > 15.57
Step-by-step explanation:
1. 15.75 is greater than 15.57. ">" means greater than.
2. 15.75 < 15.57 is wrong because 15.75 is not less than 15.57
3. 15.75 does not equal 15.57. They are not equal numbers.
4. This means " 15.75 > 15.57" is correct. Even though they are both 15 the number after the decimals are important to look at too. 75 is greater than 57.
Answer:
Step-by-step explanation:
Let the base = x inches
So, h = 2x - 1
Area of triangle = 60 square inches
(1/2) * base *height = 60
(1/2) * x * (2x-1) = 60
x *(2x-1) = 60*2
2x² - x = 120
2x² - x - 120 = 0
2x² - 16x + 15x - 15*8 = 0
2x ( x - 8) + 15 (x -8) = 0
(x-8) (2x + 15 ) = 0
x- 8 = 0 {ignore 2x +1 as it will give negative value}
x = 8
Base = 8 inches
Height = 2*8 - 1 16 - 1 = 15 inches
