Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

Mrs. Crosland asked students to factor the expression 282

Solnce55 [7]

Well formatted version of the question can be found in the picture attached below :

Answer:

Both Carlos and Irene

Step-by-step explanation:

Given the expression (28x - 8)

Carlos : 2(14x - 4)

Danny : 7(4x - 1)

Irene : 4(7x - 2)

The factored expression Given by Carlos, Irene and Danny can be expanded to check if it gives the same expression as that Given in the question :

Carlos :

2(14x - 4)

2*14x - 2*4

28x - 8

Danny :

7(4x - 1)

7*4x - 7*1

28x - 7

Irene :

4(7x - 2)

4*7x - 4*2

28x - 8

From.the expanded solutions obtained ;

Both Carlos and Irene's solution corresponds to the factored form of the original equation and are Hence correct

Step-by-step explanation:

$\frac{\frac{2x-1}{x+2}}{\frac{7}{x^{2}-12}}=\frac{2x-1}{x+2}*\frac{x^{2}-12}{7}\\\\\\=\frac{(2x-1)(x^{2}-12)}{7(x+2)}$

Last year, Josh had $20,000 to invest. He invested some of it in an account that paid 7% simple interest per year, and he invest

Ilya [14]

Answer: $12000 was invested at 7% while $8000 was invested at 9%.

Step-by-step explanation:

Based on the information given in the question, let the amount that was invested at 7% be n.

Therefore,

0.07n + 0.09(20000 - n) = 1560

0.07n + 1800 - 0.09n = 1560

-0.02n = 1560 - 1800

-0.02n = -240

n = 240/0.02

n = 120

Therefore, $12000 was invested at 7% while $8000 was invested at 9%.

Which of these statements is true? A. The interior angles of both a regular and irregular pentagon have a sum of 540o. B. The in

Varvara68 [4.7K]

Answer:

Option A is the correct answer.

Step-by-step explanation:

The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.

The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.

For a pentagon n =5.

Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°

Option A is the correct answer.
