-4x + 7 = 11 help me please!

Answers

Answer 1

Answer: -4x + 7 = 11

First, subtract 7 from both sides. / Your problem should look like: $-4x = 11 - 7$
Second, subtract 11 - 7. / Your problem should look like: $-4x = 4$
Third, divide both sides by -4. / Your problem should look like: $x = (4)/(-4)$
Fourth, change the fraction to a negative. / Your problem should look like: $x = -(4)/(4)$
Fifth, cancel 4 out. / Your problem should look like: $x = -1$

Answer: x = -1

Answer 2

Answer: you want to get "x" by its self.

-4x+7=11 (subtract 7 on both sides)
-4x=4 (divide -4 on both sides)
x=-1

Cherries cost $5 for two pounds and $7.50 for 3 pounds. a. What is the cost per pound? b. Is it constant? c. If you were to graph this situation, would you put weight or cost on the x-axis? Which one would you put on the y-axis? d. Plot the two points described e. How much would 5 pounds of cherries cost? What did you do to solve this problem?

Answers

It is Constant. The cost per pound is 2.50 dollars. two would be on the x-axis, and 5 dollars would be on the y-axis. likewise, 3 would be on the x-axis, and 7.50 dollars is on the y-axis. 5 pounds would cost : $12.50

The flow rate of the gas pump is 2/3of a gallon in 1/9 of a minute,compute the unit rate

Answers

Answer:

The unit rate is 6 gallons per minute.

Solution:

Given, The flow rate of the gas pump is 2/3 of a gallon in 1/9 of a minute,

We have to compute the unit rate?

We know that, a unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity

Here first quantity is gas and the second quantity is time

$\text { Now, unit rate }=\frac{\text { first quantity }}{\text { second quantity }}$

$=\frac{(2)/(3) \text { of gallons of gas }}{(1)/(9) \text { minute }}=((2)/(3))/((1)/(9))=(2)/(3) * (9)/(1)=2 * 3=6$

Hence, the unit rate is 6 gallons per minute.

Answer:

6 GALLONS PER MINUTE

Step-by-step explanation:

Suppose you earn $6 per hour at your part time job what will your new rate be after a 2.5% raise

Answers

2.5% means 0.025 .
After an increase of 2.5%, the new rate is (1.025) x (the old rate).

1.025 x $6.00 = $6.15 per hour.

If you work a full 40 hours in some week, you will be blessed with
a full $6 more for the week of toil than you would have collected
at the old rate.

You were not overpaid before the raise, and you must not allow
your boss to act as if you should kiss his ring or prostrate yourself
before him in return for 2.5% . It was not too long ago that 2.5% was
tantamount to being shown the way to the door, and a tacit suggestion
that you consider following in the way of the arrow.

One angle is 10 less than four times another angle. If the two angles are supplementary what is the measure of each angle? Find the correct equation one can use to solve this problem.Question 6 options:

a)

(x−10)+x=180

b)

(4x−10)+x=180

c)

4x+10=180

d)

x+(4x−10)=90

Answers

Supplementary angles must add up to 180. Let x equal "another angle." "One angle" is ten less than four times x. This would look like: 4x-10. 4x-10 and x must add up to 180: (4x-10) + x =180. This is choice B.
