Part A: 1 solution

Part B:
4(3d −7) = −52

(4)(3d) + (4)(-7)= -52

12d + -28 = -52

12d - 28 = -52

12d - 28 + 28 = -52 + 28

12d = -24

12d/12 = -24/12

d = -2

The Ratio of men to women in a certain factory is 3 to 4. There are 198 men. How many workers are there?

klemol [59]

So 3:4::198:?. 3 is to 198 as 4 is to ?. You're solving for ? so you want that on the top of the fraction. 4/3=?/198. Multiply both sides by 198. ?=(4/3)(198)=264 women. Then add the men. 264+198=462 workers.

Theresa has an umbrella stand at the beach. - All of them are blue, except for six. - All of them are yellow, except for six. -

Dmitry [639]

Answer:

3 Blue Umbrellas

Step-by-step explanation:

Given

$B \to Blue$

$Y \to Yellow$

$R \to Red$

From the question, we have:

$Y + R = 6$ ---- i.e. 6 are not blue

$B + R = 6$ ---- i.e. 6 are not yellow

$B + Y = 6$ ---- i.e. 6 are not red

Required

The number of blue umbrellas

Make B the subject in: $B + Y = 6$

$B = 6 - Y$

Substitute: $B = 6 - Y$ in $B + R = 6$

$6 - Y + R = 6$

Collect like terms

$R - Y = 6 - 6$

$R - Y = 0$

Rewrite:

$R = Y$

Substitute $R = Y$ in $Y + R = 6$

$Y + Y = 6$

$2Y = 6$

Divide both sides by 2

$Y=3$

Recall that: $B = 6 - Y$

$B = 6 - 3$

$B = 3$

How many 1/6 cup serving of rice and in 2/3 cup of rice

jok3333 [9.3K]

Answer:

4 serving cups

Step-by-step explanation:

Given

$Serving\ cup = \frac{1}{6}$

$Rice\ cup = \frac{2}{3}$

Required

The number of serving cup (n)

This is calculated by dividing the rice cup by the serving cup

$n = \frac{Rice\ cup}{Serving\ cup}$

$n = \frac{2/3}{1/6}$

Rewrite as:

$n = \frac{2}{3} \div \frac{1}{6}$

Change to multiplication

$n = \frac{2}{3} * \frac{6}{1}$

$n = \frac{12}{3}$

$n=4$
