Answer:

(x - 1)

Step-by-step explanation:

Given

8x² - 15x + 7

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 8 × 7 = 56 and sum = - 15

The factors are - 8 and - 7

Use these factors to split the x- term

8x² - 8x - 7x + 7 ( factor the first/second and third/fourth terms )

= 8x(x - 1) - 7(x - 1) ← factor out (x - 1) from each term

= (x - 1)(8x - 7) ← in factored form

The missing factor is (x - 1)

Juliette is making fruit salad. She purchased 9 2/3 ounces each of 6 differnt fruits. How many ounces of fruit did she purchase?

Dafna11 [192]

Answer:

58 bounces of fruits did Juliette purchased

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 4 feet per second or 6 miles per hour, they are called unit rates.

As per the given statement: Juliette is making fruit salad. She purchased $9\frac{2}{3}$ ounces each of 6 different fruits.

Unit rate per fruits = $9\frac{2}{3}=\frac{29}{3}$ ounces.

Number of fruits = 6

Then;

$\text{Total number of ounces of fruit} = \text{Unit rate per fruits} \times \text{Number of fruits}$

Substitute the given values we get;

$\text{Total number of ounces of fruit} =\frac{29}{3} \times 6 = 29 \times 2 = 58$

Therefore, 58 ounces of fruits did she purchased

vampirchik [111]

Answer: $1\frac{3}{5}$ hrs

<u>Step-by-step explanation:</u>

1st painter: $\frac{1}{2}$

2nd painter: $\frac{1}{8}$

1st + 2nd = Together

$\frac{1}{2}$ + $\frac{1}{8}$ = $\frac{1}{x}$

$\frac{1}{2}(8x)$ + $\frac{1}{8}(8x)$ = $\frac{1}{x}(8x)$

4x + x = 8

5x = 8

x = $\frac{8}{5}$

= $1\frac{3}{5}$
