Answer:
5 : 6
Step-by-step explanation:
The ratio is ...
girls : boys = 20 : 24
By removing a common factor of 4 from each of these numbers, the ratio can be reduced to lowest terms:
girls : boys = 5 : 6
Answer:
x= -8
Step-by-step explanation:
Hope this helps my guy
- 4 = 25
First, simplify
to
/ Your problem should look like:
- 4 = 25
Second, multiply both sides by 5. / Your problem should look like: 3p - 20 = 125
Third, add 20 to both sides. / Your problem should look like: 3p = 125 + 20
Fourth, simplify 125 + 20 to get 145. / Your problem should look like: 3p = 145
Fifth, divide both sides by 3. / Your problem should look like: p =
Answer as fraction: p =
Answer as decimal: 48.3333
Answer:
2
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (4, - 6)
d =
=
=
= = = × = 2
So this translates to:
5e + 5n = 25.95
2e + 6n = 22.38
One way to solve that is to multiply the top equation by 2, and the bottom equation by 5:
10e + 10n = 51.90
10e + 30n = 111.90
Then subtract the top from the bottom to get:
20n = 60
and divide by 20 to get
n = 3
So you know that note paper costs $3. Substituting that into the top equation you get:
5e + 5*3 = 25.95 or
5e + 15 = 25.95
Subtracting 15 from both sides you get:
5e = 10.95
Dividing by 5 you get:
e = $2.19
