Let "x" represent the age of Brian.
Andrew is elder than Brian by 2 years, we can symbolize his age as "x+2"
Frank is twice as old as Andrew, we can symbolize his age as "2(x+2)"
Sarah has half the age of Brian's, we can symbolize her age as "x/2"
Frank ans Sarah's ages differ by 40 years, we can symbolize this as:
Solve the term is parenthesis
x=24 years
Andrew's age is
Andrew is 26 years old
Answer:
- 40
Step-by-step explanation:
The absolute value always returns a positive value , that is
- | - 40 | = - | 40 | = - 40
She did not multiply both sides of the equation by 2.
2x-6y =-2
<u>+ 2x+6y=3
</u><u /> 4x =1
x=1/4
y=5/12
To do this, we have to multiply the 7 feet diameter by pi to get the circumference because the formula for circumference is
, or circumference = pi times diameter. 7 x 3.14 (pi rounded) = 21.98
Answer: 21.98 feet
Continue the slop until it hits the y axis and that point will be your y intercept
