Answer:
Cheryl's age = x = 7 years
Rita's age = y = 17 years
Step-by-step explanation:
Let
Cheryl's age = x
Rita's age = y
Two years ago, Rita was three times older than Cheryl
(y - 2) = 3(x - 2)
y - 2 = 3x - 6
y = 3x - 6 + 2
= 3x - 4
y = 3x - 4
In 3 years, Rita will be twice older than Cheryl
(y + 3) = 2(x + 3)
y + 3 = 2x + 6
y = 2x + 6 - 3
= 2x + 3
y = 2x + 3
Equate both equations
3x - 4 = 2x + 3
Collect like terms
3x - 2x = 3 + 4
x = 7 years
Substitute x = 7 into
y = 2x + 3
= 2(7) + 3
= 14 + 3
= 17
y = 17 years
Cheryl's age = x = 7 years
Rita's age = y = 17 years
Step-by-step explanation:
use the formula: (a+b)³ = a³+3a²b+3ab²+b³
and place the corresponding values.
Answer:
I'm sorry you have a lot of Homework. All i know is the 1st step... i believe their are 3 steps to this question, I wish you the best of luck my friend!
Step-by-step explanation:
1st step =
x=36
<span>First step is find total height of all the figures expressed in feet:
Liem: 6 ft 2 inch = 6,167 ft
Eli: 5 ft 9 inch = 5,75 ft
Faith 6 ft
Simon: 5 ft 4 inch = 5,34 ft
To calculate the total height we need to know that 12 inches are 1 foot
6’2”+5’9”+6+5’4”= 22 ft 15 inch = 23 ft 3 inch
Another way is by adding decimal figurel:
6,167 + 5,75 + 6 + 5,34 = 23,25 feet
Then we know that 3 feet are 1 yard, so then total height is:
23,25 / 3 = 7,75 yards</span>
