five times a certain number, minus 5 is equal to 7 more than three times the number

Answers

Answer 1
let’s start with putting the unknown to x, in this case it is the number.

5x-5=7+3x, so now we just solve this equation.

5x-3x=7+5
2x=12
x=6

the number is 6
Answer 2
Final answer:

To solve the equation, we can set up the equation as '5x - 5 = 3x + 7' and solve for x using algebraic manipulations.

Explanation:

Let's solve this equation step by step. Let's assume that the number we are looking for is 'x'.

According to the question, 'five times a certain number, minus 5' can be represented as 5x - 5. And 'seven more than three times the number' can be represented as 3x + 7.

So, we can write the equation as 5x - 5 = 3x + 7. Now, let's solve for x.

Subtract 3x from both sides: 5x - 3x - 5 = 3x - 3x + 7.

Simplify: 2x - 5 = 7.

Add 5 to both sides: 2x - 5 + 5 = 7 + 5.

Simplify: 2x = 12.

Divide both sides by 2: 2x/2 = 12/2.

Simplify: x = 6.

Therefore, the solution to the equation is x = 6.

Emanuel is planting trees along a new city sidewalk. He plants the same number of trees on each city block. After 3 blocks, he has planted 15 trees. After 5 blocks, he has planted 25 trees. At what rate is Emanuel planting trees?

Answers

Answer:

Every 1 Block he is planting 5 tree's.

Step-by-step explanation:

There are multiple ways you can do it but the easiest I prefer is just to divided The Tree's by the Blocks.

Ex: 6 Blocks is 30 trees, Divide 30 by 6 and you get 5 for every block.

Final answer:

Emanuel is planting trees at a rate of 5 trees per block. This is determined by dividing the total number of trees by the total number of blocks planted.

Explanation:

Emanuel is planting trees at a consistent rate. To find this rate, we can set up a simple ratio.

He planted 15 trees in 3 blocks, which simplifies to 5 trees per block. This can be confirmed by looking at the second part of the problem. After 5 blocks, he had planted 25 trees. If we divide the total number of trees by the total number of blocks (25 trees / 5 blocks), we also get 5 trees per block.

Therefore, the rate at which Emanuel is planting trees is 5 trees per block.

320 cubic inches

128 cubic inches

448 cubic inches

Step-by-step explanation:

Step 1:

Given,

Dimensions of the first rectangular prism = l * b * h = 16*5*4

[length is 16 as the total length is 20 and the width of the 2nd prism till the dotted line is 4]

Dimensions of the second rectangular prism = l * b * h = 4*4*8

We need to determine  volume of the 2 prisms and the whole figure. The volume of  rectangular prism can be obtained by multiplying the length breadth and the height.

Step 2:

Volume of the first prism = l * b * h = 16*5*4 = 320 cubic inches

Volume of the first prism = l * b * h = 4*4*8 = 128 cubic inches

The volume of the whole figure is the sum of the 2 rectangular prisms = 320 + 128 = 448 cubic inches

"and six" relates to "sum".

So when you put these together it would be 5x+6=3

5(x+6)=3.
You need the sum first. So the number and 6 need to go in the parenthesis. Then put the 5 outside of the parentheses like the question asks. It says five times the sum so after the sum you need to multiply by 5.

Type the correct answer in each box. Use numerals instead of words.
The domain of this function is {-12, -6, 3, 15}.



Complete the table based on the given domain.

Answers

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15

Solution:

The function is [tex]y=-\frac{2}{3} x+7[/tex].

The domain of the function is {–12, –6, 3, 15}.

Substitute x = –6 in the function to find y.

[tex]$y=-\frac{2}{3} (-6)+7[/tex]

y = 4 + 7

y = 11

Substitute y = 5 in the function to find x.

[tex]$5=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$-2=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = 3

Substitute x = 15 in the function to find y.

[tex]$y=-\frac{2}{3} (15)+7[/tex]

y = –10 + 7

y = –3

Substitute y = 15 in the function to find x.

[tex]$15=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$8=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = –12

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15
