This can be solve by establishing equations.
let x be the miles mrs. storey drove
y be the miles mr storey drovee
the first equation is
y = 3x
second equation
x + y = 3200
then substitute equation 1
x + 3x = 3200
4x = 3200
x = 800 miles mrs storey drove
y = 3x = 2400 miles mr storey drove
Answer:
The correct answer is 3/8
Step-by-step explanation:
It was in my practice and I had gotten it correct.
Yes. Because both equals 1 whole.
Answer:
<h2>n>8</h2>
Step-by-step explanation:
Step one:
given data
needed amount= $80
the amount already saved= $8
earnings per hour= $9
let the number of hours worked be n
and let y represent the total
the situation represented linearly is
y=mn+c
Step two:
substituting our data to find n
9n+8>80
9n>80-8
9n>72
divide both sides by 9
n>72/9
n>8
Therefore he must work a minimum of 8houees
6^(x - 3/4) = 6^(1/2)
since 6 is the base on each side:-
x- 3/4 = 1/2
x = 1/2 + 3/4
x = 5/4 (or 1 1/4)
