Answer:

Simplifying

6 + -8x = 7x + -9x + -36

Reorder the terms:

6 + -8x = -36 + 7x + -9x

Combine like terms: 7x + -9x = -2x

6 + -8x = -36 + -2x

Solving

6 + -8x = -36 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

6 + -8x + 2x = -36 + -2x + 2x

Combine like terms: -8x + 2x = -6x

6 + -6x = -36 + -2x + 2x

Combine like terms: -2x + 2x = 0

6 + -6x = -36 + 0

6 + -6x = -36

Add '-6' to each side of the equation.

6 + -6 + -6x = -36 + -6

Combine like terms: 6 + -6 = 0

0 + -6x = -36 + -6

-6x = -36 + -6

Combine like terms: -36 + -6 = -42

-6x = -42

Divide each side by '-6'.

x = 7

Simplifying

x = 7

Use rounding to estimate the product

sdas [7]

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

whole number as it and cancel the fraction

- Ex: If the mixed number is $2\frac{3}{4}$ , 3 is more than

half 4 then we will add 2 by 1 and cancel the fraction part, the

mixed number $2\frac{3}{4}$ after rounding is 3

- Ex: If the mixed number is $5\frac{1}{4}$ , 1 is less than

half 4 then we will keep 5 as it and cancel the fraction part, the

mixed number $5\frac{1}{4}$ after rounding is 5

* Lets solve the problem

∵ In the part $4\frac{3}{4}$ 3 is more than half 4

∴ The rounding value of $4\frac{3}{4}$ is 5

∵ In the part $7\frac{2}{17}$ 2 is less than half 17

∴ The rounding value of $7\frac{2}{17}$ is 7

∴ $4\frac{3}{4}*7\frac{2}{17}=5*7=35$

* <em>The estimate of the product is about 35</em>

Kamila [148]

This question is incomplete

Complete Question

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

The entire little league division that The Hawks belong to has the same ratio of redheads to everyone else.

What is the total number of redheads in that division if the total number of players is 126?

Answer:

18 red heads

Step-by-step explanation:

We are told:

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

Hence, we have the ratio

7: 5: 2

Adding up the ratios together

7 + 5 + 2

= 14

The total number of players is 126

Hence, the total number of redheads in that division is

2/14 × 126

= 18 red heads.

Step-by-step explanation:

step 1. x = .484848 . . . repeats

step 2. 100x = 48.48484848 . . . (multiply by 100)

step 3. subtract x from 100x : 99x = 48

step 4. x = 48/99 (now add the 2 back in)

step 5. answer: 2-48/99.
