What equation is equivalent to 5(2p - 6)= 40

Answers

A. 10p-30=40 would be the answer
First you simply both sides of the equation , add 30 to both sides, and divide both sides by 10. Then p=7
=2p-6=40/5
Divide 40 by 5 to get 8
= 2p-6=8
Move 6 with 8 then add them you will get 14
=2p=8+6
Divide both sides by 2
=2p=14
=p=14/2
Divide 14 by 2 to get 7
The final answer is
P=7

Turn y=1/2x + 3/2 into standard form ​

Answers

Answer:  x - 2y = -3

=============================================

Work Shown:

y = (1/2)x + 3/2

2y = x + 3 .... multiply every term by the LCD 2

2y-x = 3 ... subtract x from both sides

-x+2y = 3

x-2y = -3 ... multiply both sides by -1

The last step is done so that the x coefficient is positive

The equation is in the form Ax+By = C with

A = 1B = -2C = -3

You could have your answer as -x+2y = 3, since that is also in standard form. But many math textbooks make A > 0.

Individuals of the same approximate weight running 6 mph or 1 mile every ten minutes have a calorie use factor of 62% of their weight; i.E., calories burned = (weight)(0.62). If they run an 8-minute mile, the factor is 65%. A man weighs 180 lb. He jogs a mile in 8 minutes. How many calories has he used up?

Answers

Answer: He has used up 117 calories.

Step-by-step explanation:

Given, For 62% as factor, calories burned (E)= (weight)(0.62).

Also, if they run an 8-minute mile, the factor is 65%.  [given]

Then, calories burned (E)= (weight)(0.65). [65%=0.65]

Weight of man = 180 lb

Then, calories burned (E)= 180 x (0.65).

= 117

Thus , he burned 117 calories.

So, he has used up 117 calories.

Answers

Answer:

Scarce demand / inflation

Inflation is the term used when a price increases in the market.

HELP PLS find measure of w in this trapezoid

Answers

Answer:

m<w= 36°

Step-by-step explanation:

Step 1) Applying geometric and algebraic knowledge, the two angles to the left are both 90, and equal to 180. If you add those two angles and the 146°, you will be given 326 in total.

90+90= 180 +146 = 326

Step 2) With knowledge that the sum of all interior angles inside of a quadrilateral add up to 360, subtract 326 from this.

360-326=36

Final product: m<w=36°

5% commission rate of 14.98 is what?

Answers

Answer:

$0.75

Step-by-step explanation:

To find the answer we simply multiply the amount of money earned by the percentage.

So the total amount of money = $14.98

And the percentage = 5%

But I order to calculate this we must first turn the percentage into a decimal. To do this we decide the number of the percentage by 100

In this case that is 5/100=0.05

We can now multiply this by the amount of money to get 0.05*14.98=0.749

We then round our answer to two decimal places (because money can not go past two) to get $0.75
