If r(x) = 3x - 1 and s(x) = 2x + 1, which expression is equivalent to (r/s)(6)?

zavuch27 [327]

Answer:

17/13

Step-by-step explanation:

r(6) = 3(6) - 1 = 17 and s(6) = 2(6) + 1 = 13.

Then (r/s)(6) = 17/13.

If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?

Zina [86]

Answer:

18

Step-by-step explanation:

First, you would do a proportion

$\frac{3}{50}$ = $\frac{x}{300}$

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

Find the measures of an interior angle 48° + X + (X -44°)

Sliva [168]

Answer:

X = 88°
(X-44°) = 44°

Step-by-step explanation:

We assume the given sum is the sum of interior angles of a triangle, so is equal to 180°.

48° +X +(X -44°) = 180°

2X +4° = 180° . . . . . . . . . . collect terms

X +2° = 90° . . . . . . . . . . . .divide by 2

X = 88° . . . . . . . . . . . . . . . subtract 2°

Then the other interior angle is ...

(X -44°) = 88° -44° = 44°

The unknown interior angles are ...

X = 88°
X-44° = 44°
