Answer:

A proportional relationship is written as:

y = k*x

where k is the constant of proportionality.

A general word problem that represents one of these relationships can be:

If each burger costs $1.50, what would be the cost of buying x burgers?

The cost of x burgers will be x times $1.50, so if we define y as the total price, we will have the relation:

y = $1.50*x

Which is a proportional relationship where the constant of proportionality is $1,50

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

GrogVix [38]

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

Hello and Good Morning/Afternoon

Let's tale this problem step-by-step:

What does the problem want:

$\hookrightarrow \text{the unemployment compensation}$

Employment compensation =55% of the average of the last 26-week salary

$\hookrightarrow \text{Average of Natalia's salary} = (\text{all the salaries added up}) / (\text{number of weeks})\\\hookrightarrow \text{Average of Natalia's salary} = 18940 / 26 = 728.46 \text{ (Rounded down)}$

⇒ 55% of that average

$\hookrightarrow \frac{55}{100} *728.46 = 400.65$

Answer: $400.65

Hope that helps!

How many cubic centimeters is 5 cubic meters.

tresset_1 [31]

The key to solving this question is first knowing how many cubic cm are in one cubic m:

The ratio is always 1000000 cubic cm in 1 cubic meter.

Knowing this, we calculate how many cubic cm are in 5 cubic meters!

1000000 cubic cm = 1 cubic m
x cubic cm 5 cubic m

x = 1000000 cubic cm x 5 cubic m ÷ 1 cubic m
x = 5000000 cubic cm

Hope this helps!
