Solve for k. 9(3-2x)=2(10-8x)

Mathematics
1 answer:
GrogVix [38]3 years ago
3 0

Answer:

Step-by-step explanation:

9(3−2x)=2(10−8x)

Step 1: Simplify both sides of the equation.

9(3−2x)=2(10−8x)

(9)(3)+(9)(−2x)=(2)(10)+(2)(−8x)(Distribute)

27+−18x=20+−16x

−18x+27=−16x+20

Step 2: Add 16x to both sides.

−18x+27+16x=−16x+20+16x

−2x+27=20

Step 3: Subtract 27 from both sides.

−2x+27−27=20−27

−2x=−7

Step 4: Divide both sides by -2.

−2x −2  =  −7 /−2  

x= 7/ 2

Answer:

x= 7/ 2

Stephanie spent 50% of x hours at her part-time job. What is x if 50% of x is about 46 hours? Explain how you estimated and whic
Liono4ka [1.6K]

Answer:

92 hrs

Step-by-step explanation:

Given 50% of x = 46 hrs

Then

50% /100% x X = 46

0.5 x X = 46

0.5x = 46

Divide both sides by 0.5

0.5x/0.5 = 46/0.5

x = 92

x is 92 hrs

Question 4
PIT_PIT [208]

Answer:

C = 23.5 in

Step-by-step explanation:

θ = 43°

The length of the side opposite to θ = 16 in.

Hypotenuse = DK

Apply trigonometric ratio, thus:

sin(θ) = opp/hyp

Plug in the values

sin 43 = 16/DK

Multiply both sides by DK

DK*sin 43 = 16

Divide both sides by sin 43

DK = 16/sin 43

DK = 23.5 (nearest tenth of an inch)
