solve for t

7t–8=10+2t

Answers

Answer:

t=18/5

Step-by-step explanation:

7t-8=10+2t

+8 on both sides

7t-8+8=10+2t+8

combine like terms

7t=18+2t

-2t on both sides

7t-2t=18t+2t-2t

combine like terms

5t=18

divide by 5

5t/5=18/5

t=18/5

Add 8 to both sides:

7t=18+2t

Subtract 2t from both sides:

5t=18

Divide both sides by 5:

t=18/5

t=3.6

F. 8

G. x/2-7
H. x - 8

Answers

Brown Eyes: 1/2x - 1
Blue Eyes: 1/2x-6

Let the students who have green eyes be y.

1/2x-1+1/2x-6= x-y (Because the RHS is the students with brown and blue eyes and hence x-y on the LHS)
x-7=x-y
-y=-7

4. Chris and Keith went to a carnival. Chris started with 80 tickets and spent x tickets at the carnival, Keith started with 140 tickets and spent 2x tickets at the carnival. At the end of the night, they had the same number of tickets left over. How many tickets did Chris spend at the carnival?​

Answers

Answer: x=20

Step-by-step explanation:

3x+80=140

3x=60

x=20

Answer: Chris spent 60 tickets at the carnival.

Step-by-step explanation:

At the end of the night, both Chris and Keith had the same amount of tickets, so:

80 - x = 140 - 2x

Now, solve the equation. Start by bringing the -2x to the left side.

80 - x + 2x = 140

Bring the 80 to the right side so the variables are isolated.

-x + 2x = 60

Add like terms.

x = 60

Check the work.

Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20

Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20

So, Chris spent 60 tickets at the carnival.

2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Will works at a shoe store. For every 2 pairs of striped shoes he sells, he sells 3 pairs of neon shoes. Will sold 12 pairs of striped shoes. How many pairs of neon shoes did he sell?

Answers

Answer: 18 pairs of neon shoes

Step-by-step explanation: It's a ratio.

2/3 = 12/x. Cross Multiply

2x =12(3). 2x=36 Divide by 2

x = 18

The required number of pairs of neon shoes sold is 18 corresponding to 12 striped shoes.

Given that,
For every 2 pairs of striped shoes he sells, he sells 3 pairs of neon shoes. when selling 12 pairs of striped shoes. How many pairs of neon shoes did he sell is to be determined.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Let the number of neon shoes for the corresponding 12 pairs of striped shoes be x,
According to the question,
2 / 3 = 12 / x
x = 36 / 2
x = 18

Thus, the required number of pairs of neon shoes sold is 18 corresponding to 12 striped shoes.

Find the x- and y- intercepts of this two-variable equation:

y = 5 + x

Answers

To find the x-intercept, we set y = 0 and solve for x:

0 = 5 + x

Subtracting 5 from both sides:

x = -5

Therefore, the x-intercept is -5.

To find the y-intercept, we set x = 0 and solve for y:

y = 5 + 0

Simplifying:

y = 5

Therefore, the y-intercept is 5.

The x-intercept is (-5, 0).

The y-intercept is (0, 5).

Answer:

x: -5,0
y: 0,5

Step-by-step explanation:

2/3 of the pens in a box are blue. 1.2 of them are black. The rest of them are red. There are 36 more blue pens than red pens. How many pens are there altogether? Also explain please, will make brainliest on the best answer.

Answers

Answer:

Option B. For every 5 red pens, there are 15 blue pens.

Step-by-step explanation:

The statement expressed the ratio of the red pens to the total as 1 : 4.

This means that for every red pen in the box, there are 4 blue pens.

So, statement A is correct.

Let's skip B an look at other statements as well:

For C, the ratio will be 15 : 60 which translates to 1 : 4. So C is true.

Let's look at D.

This is an interesting one. The problem defines 18 as blue. So it means that 24 - 18 = 6

6 pens will be blue. Again 6 : 24 gives us 1 : 4. So D is true.

B gives us 5 : 24 which is not true.

For every 5 red = to 15 blue 5:15
