Answer:
Step-by-step explanation:
P = $295
r =7%
t = 270 days = 270/365
Interest = Prt
= $ 15.28
Amount = 295 + 15.28
Amount = $310.28
<u>STEPS:</u>
1) set up an equation. use x as a variable
2x + 3x = 25
2) solve the equation for x:
5x = 25
x = 5
3) Now that you know the value of x, substitute it into the expression for how any girls there are, which is "3x" (since the ratio of BOYS to GIRLS is 2:3):
3x
= 3(5)
= 15
So 15 is your answer, and there are <u>15 girls in the class.</u>
15.50+1.50x =26
1.50x = 10.50
x = 7
answer: he can ride 7 in one day
Answer:
c) 25 degrees
Step-by-step explanation:
85 - 30 - 30 = 25
answer:
the number is one
work:
let's analyze the question.
15 times a number is..
so, right away we have 15n.
.... decreased by eight...
we are subtracting 8, so 15n - 8
...the result is 17.
so, 15n - 8 will equal 17.
Find the number.
now, we solve for n.
15n - 8 = 17 (add 8 to both sides)
15n = 15 (divide both sides by 15)
n = 1
so, the number is one. hope this helps, have a great day!
