X = - 21/4

2/3x - 4 1/2 = - 8
2/3x = - 8 + 4 1/2

- 8 + 4 = - 4. Then do - 4 + 1/2 = - 3 1/2

2/3x = - 3 1/2

- 3 1/2 is the same as = - 7/2

2/3x = - 7/2

Flip the coefficient on the variable and multiply both sides by it.

(3/2)(2/3)x = - 7/2(3/2)

x = - 7/2(3/2)

x = - 21/4

WILL MARK BRAINLIEST!!!!PLZ HELP!!!! An expression is shown below: 3pf2 − 21p2f + 6pf − 42p2 Part A: Rewrite the expression by f

Lesechka [4]

Answer:

See below.

Step-by-step explanation:

So, we have:

$3pf^2-21p^2f+6pf-42p^2$

PART A:

Find the GCF. Notice that we have a 3 in every term and a p in every term. Thus, the GCF is 3p:

$3p(f^2-7pf+2f-14p)$

This is the most we can do.

PART B:

Continue from where we left off. Factor the entire expression:

$3p(f^2-7pf+2f-14p)\\3p(f(f-7p)+2(f-7p))\\3p((f+2)(f-7p))$

If a bag contains 12 quarters, 6 dimes, and 18 nickles, what is the part-to-whole ratio of nickles to all coins?

gladu [14]

There are 18 nickels and 36 total coins
18:36 is your original proportion, but we can simplify.
Divide by 2
9:18
Divide by 9.
1:2 is your final answer.
A.) is correct.

In the triangle ABC if angle A is 20 degrees, angle B is 35 degrees and the side between (side C) them is 100, what is the appro

docker41 [41]

Answer:length of side a is 42

Step-by-step explanation:

The given triangle ABC is shown in the attached photo. The length of side BC is a. The length of side AC is b and the length of side AB is c = 100

The sum of the angles in a triangle is 180 degrees. Therefore.

Angle A + angle B + angle C = 180. Therefore,

20 + 35 + angle C = 180

55 + angle C = 180

Angle C = 180 - 55 = 125 degrees. To determine the length if a, we would apply the sine rule which is expressed as

a/SinA = b/SinB = c/SinC

Therefore,

a/Sin20 = 100/Sin125

aSin125 = 100sin20

a × 0.8192 = 0.342 × 100

0.8192a = 34.2

a = 34.2/0.8192

a = 41.75

Approximately 42
