Answer:
The score that separates the top 59% from the bottom 41% is 31.68
Step-by-step explanation:
3/2 = 2q
q = 3/2 ÷ 2
q = 3/2 × 1/2
q = 3/4
Answer:
what i would do is just divide each of the fractions until you get 0.6.
for example if you divide 2/3 you get 0.6
which is your answer, or B
Step-by-step explanation:
First you need to find the slope, which is (y2-y1)/(x2-x1)
Plug the points in as (1-4)/(-1-1) -> -3/-2
The slope is 3/2, or 1.5
Point slope form is y-y1 = m(x-x1)
Plug in the slope (m) and the first point
y-4 = 1.5(x-1) <-- That's point slope form
To get standard form (ax+by=c), you can use point slope form
y - 4 = 1.5(x - 1)
y - 4 = 1.5x - 1.5
y = 1.5x + 2.5
-1.5x + y = 2.5 <-- Standard Form
Answer:
S = x + 10
R = 2x + 10
Step-by-step explanation:
If R is Roberto's age, and S is his sister's age, then:
R = S + x
R − 10 = 2 (S − 10)
Solve with substitution.
S + x − 10 = 2 (S − 10)
S + x − 10 = 2S − 20
S = x + 10
R = 2x + 10
