Answers

3 (2y-5) + 15 =12
6y-15+15=12
6y=12
y=2

To find value of y:-

________________________________

Step 1:

3 ( 2y - 5 ) + 15 = 12

Right the equation

________________________________

Step 2:

6y-15+15=12

open the brackets and multiply 3 with 2y - 5

________________________________

Step 3:

6y=12

Subtract 15 with 15 to get 0

________________________________

Step 4:

y=12÷6

divide 12 with 6 to get value for y

________________________________

Step 5:

y=2

Value of y comes 2

________________________________

Confermimng :

3(2×2-5)+15=12

3(4-5)+15=12

3(-1)+15=12

-3+15=12

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.

Answers

Answer:

Down Below :))

Step-by-step explanation:

This is quite simple.

Take a look at both of the numbers, see how their both 29?

Subtracting 29 - 29 = 0

Explanation: The average temperature was 0 because when subtracting 29 - 29, it gives you 0.

The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.

Toby is installing a new storage building in the back of his yard. The building measures 10 ft. x 12 ft. He’ll need a 10 foot long, 12 foot wide, and 4 inch deep slab for the project. Help him estimate the cost of his concrete project.

Answers

Answer:

Not sure if this is correct but i believe the price would be $20,000

Step-by-step explanation:

Yoour perimeter is 120ft and it is 1/3 of a foot. So i did 120/3 and i got 40. The 40 is how many square feet you will need. you do 40x500 and i got $20,000. Sorry if this is wrong as i was kind of confused for a moment

The required cost of the concrete project is given as $740.7.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of the slab is given as,
= length × width × height
= 10 × 12 × 4/12
= 40 cubic feet,

Now,
The cost of a concrete slab is given by
= Total volume (cubic foot) x $500/27
= 40 × 500 / 27
= $740.7

Thus, the required cost of the concrete project is given as $740.7.

First solve 2(5m-8)

2x5m= 10m 2x(-8)= -16


Now it looks like this


16+10m-16-m=36


Cancel 16 with the -16

10m-m=36
