What is the answer to 8x-2=-9+7x
Answers
Well I don't know !
Let's get together and figure it out. Are you with me ?
You said that 8x - 2 = -9 + 7x
Add 2 to each side: 8x = -7 + 7x
Subtract 7x from each side: x = -7
Now that wasn't so bad, was it ?

90% percentage of the total deliveries has Lamar completed.
What do percentage means?
- a relative number representing the hundredth part of any quantity One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.
- The most fundamental use of percentages is to compare one number to another, with the second number rebased to 100.
- Percentage simply means "per hundred," and the sign for percentage is%. One percent (or 1%) is one hundredth of a total or whole number and is computed by dividing the whole or entire number by 100.
Total deliveries = 40
completed = 36
percentage of the total deliveries has Lamar completed
= 36/40 * 100 = 90%

Answer:
61 cm for each book shelf.
Step-by-step explanation:
First it gives you the width of the boxes so you add them together
132 + 108 + 94 = 334
so 334 cm has already been used out of 456 cm.
Next you will 456 - 334 = 122 cm left over
if they are building 2 book cases you with take what cm's you have left and divide it by 2
122 / 2 = 61
So that means each book case will be 61 cm's wide

Step-by-step explanation:
We have been given a system of equations. We are asked to find the solution of our given system.
Equate both equations:
Split the middle term:
Use zero product property:
Now, we will substitute both values of x, in our given equation to solve for y.
One solution:
2nd solution:
Therefore, option A is the correct choice.
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = x² - 4x + 8 → (1)
y = 2x + 3 → (2)
Since both express y in terms of x we can equate the left sides, that is
x² - 4x + 8 = 2x + 3 ( subtract 2x + 3 from both sides )
x² - 6x + 5 = 0 ← in standard form
(x - 1)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 5 = 0 ⇒ x = 5
Substitute these values into (2) for corresponding values of y
x = 1 : y = (2 × 1) + 3 = 2 + 3 = 5 ⇒ (1, 5)
x = 5 : y = (2 × 5) + 3 = 10 + 3 = 13 ⇒ (5, 13)
Solutions are (1, 5) and (5, 13)
