Answer:

Step-by-step explanation:

10 - 4m + 7m = m - 10

Simply both sides:

10 + -4m + 7m = m + -10

Combine like terms:

( -4m + 7m) + (10) = m - 10

3m + 10 = m -10

3m + 10 = m - 10

Subtarct m from both sides:

3m + 10 - m = m - 10 - m

2m + 10 = -10

Subtract 10 from both sides:

2m + 10 - 10 = -10 - 10

2m = -20

Divide both sides by the 2:

2m/2 = -20/2

m = -10

Answer =====> m = -10

Hope that helps : ) -P-

The food bank has 1774.4 oz of chicken.If 12.6 oz is 2 servings,how many servings of chicken does this provide?

diamong [38]

Answer:

281 servings

Step-by-step explanation:

From the table attached,

We will apply the unitary method to solve this problem.

∵ 12.6 oz of chicken represents number of servings = 2

∴ 1 oz of chicken will represents number of servings = $\frac{2}{12.6}$

∴ 1774.4 oz of chicken will make the total servings = $\frac{2}{12.6}\times 1774.4$

= 281.65

≈ 281 servings

Therefore, total number of servings provided = 281

If y varies directly as x, and y = 25 when x = 5, find y when x = 25.

zimovet [89]

A.125
Because to get from 5 to 25 you need to multiply by 5 so 25 times five equals 125

Topic: Parallel and Perpendicular Lines

Eddi Din [679]

Answer:

Step-by-step explanation:

an equation perpendicular to the equation given will have a slope of -1, because a perpendicular slope is opposite and reciprical. if it goes through the point 4,-1 and has a slope of -1, the y intercept has to be 3. y = -x + 3

parallel lines have to have the same slope of 3.

Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they w

matrenka [14]

Answer:

1.15p + 285 = 5.84

Step-by-step explanation:

This problem has two equations. Total cost and Total pounds. The cost and the pounds

p = apple pounds

b = banana pounds

Cost

1.90p + .75b = 5.84

Pounds

p + b = 3.8

Now we use the substitute method for system of equations to solve

p + b = 3.8

b = -p + 3.8

Now that we know what b equals, substitute is for b in the cost equation.

1.90p + .75b = 5.84

1.90p + .75(-p+3.8) = 5.84

distribute / multiply .75 by (-p+3.8)

1.90p + -.75p + 2.85 = 5.84

Combine the p values

1.15p + 285 = 5.84
