Answer: 6

Step-by-step explanation:

2(x-3)+7=13

simplify both sides of the equation

(2)(x) + (2)(-3) + 7 = 13 (distribute)

2x + -6 + 7 = 13

(2x) + (-6+7) = 13 (combine like terms)

2x + 1 = 13

subtract 1 from both sides

2x + 1 - 1 = 13 - 1

2x = 12

Divide both sides by two

2x/2 = 12/2

x = 6

Write the equation (in point-slope form) for the line parallel to y = x + 4 and passes

Tanya [424]

Answer:

$y = x-7$

Step-by-step explanation:

Step 1: Write the equation in point-slope form

Point Slope Form: $y-y_{1}=m\left(x-x_{1}\right)$

Plug in the numbers and solve

$y - (-2) = 1(x - 5)$

$y + 2 = x - 5$

$y + 2 - 2 = x - 5 - 2$

$y = x-7$

Answer: $y = x-7$

11 1/2 and 13 3/4 is?

Tpy6a [65]

This would depend on what you are asking for.

If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.

You get this by finding a common denominator. In this case, that can be 4.

Turn 1/2 in to 2/4.

Next, you add 11 and 13 to get 24.

Then, you’ll add 2/4 and 3/4. You will get 1 1/4

Add 24 and 1 1/4. You have your answer of 25 1/4

(T+10.5) + 2t + 90 = 180

Masja [62]

Answer:

x = 26.5

Step-by-step explanation:

Step 1: Write equation

(t + 10.5) + 2t + 90 = 180

Step 2: Solve for t

Combine like terms: 3t + 100.5 = 180

Subtract 100.5 on both sides: 3t = 79.5

Divide both sides by 3: t = 26.5

Step 3: Check

Plug in x to verify it's a solution.

Substitute: (26.5 + 10.5) + 2(26.5) + 90 = 180

Parenthesis: 37 + 56 + 90 = 180

Add: 180 = 180

∴ x = 26.5
