Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
First you need to add the prices to get 85.55. Then 100 - 85.55 is 14.45.
She will have $14.45 leftover
The number of batches she can make is = 5 batches
<h3>Calculation of total number of batches</h3>
The amount of dough used to make each batch = 12oz
The total amount of dough she has= 60oz
Therefore, the number of batches she can make from the total dough available = b
Using the equation:
(dough for one batch) × (number of batches) = (total amount of dough)
which is = 12× b = 60
b= 60/12
b= 5 batches

Answer:
The solution for y is y = 2x + 1
Step-by-step explanation:
* <em>Lets explain how to solve an equation for one of the variables</em>
- We need to solve the equation 16x + 9 = 9y - 2 x for y
- That means we want to find y in terms of x and the numerical term
- the equation has two sides, one side contains x and numerical term
and the other side contains y and x
- We need to separate y in one side, and other term in the other side
* <em>Lets do that</em>
∵ 16x + 9 = 9y - 2x
- Add 2x to both sides to cancel -2x from the right side
∴ 16x + 2x + 9 = 9y - 2x + 2x
- Add like terms in each side
∴ 18x + 9 = 9y
- Divide each term by the coefficient of y ⇒ (÷9)
∴ (18 ÷ 9)x + (9 ÷ 9) = (9 ÷ 9)y
∴ 2x + 1 = y
- Switch the two sides
∴ y = 2x + 1
* The solution for y is y = 2x + 1
