A bag contains white marbles and red marbles, 16 in total. The number of white
Sonbull [250]

Answer:

11

Step-by-step explanation:

Let's call the white marbles w and the red marbles r. We can write:

w + r = 16 (1)

w = 3r - 4 (2)

3r - 4 + r = 16 (3) (Substitute (2) into (1))

4r = 20 (simplify)

r = 5 (divide by 4) which means w = 16 - 5 = 11

A unit rate is a value compared to how many units
Aloiza [94]

Answer:

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour

Step-by-step explanation:

Ex: If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

120/3 = 40/1

The unit rate of 120 students for every 3 buses is 40 students per bus. You could also find the unit rate by dividing the first term of the ratio by the second term.

2/3 (x - 7) = -2 what does x equal<br><br> (2/3 is a fraction not dividing)
ozzi

Answer:

x = 4

Step-by-step explanation:

Given

\frac{2}{3}(x - 7) = - 2

Multiply both sides by 3 to clear the fraction

2(x - 7) = - 6 ← distribute left side

2x - 14 = - 6 ( add 14 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4
