SELECT ALL the expressions that are equivalent to -2(4 - 3x) + (5x - 2)

A.) 2x - 10

B.)11x - 10

C.)-8 + 11x - 2

D.)-8 - 11x - 2

E.) -8 + 6x + 5x - 2

F.)-8 - 3x + 5x - 2

Answers

Answer:

option B

Step-by-step explanation:

-2(4 - 3x) + (5x - 2)=

-8+6x+5x-2= 11x -10

-8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is -2(4 - 3x) + (5x - 2)

We have to find the equivalent expression

x is the variable in the expression

Equivalent expressions are expressions that work the same even though they look different.

Let us apply distributive property

-8+6x+5x-2

Combine the like terms

11x-10

Hence, -8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

Nate has $50 to spend at the grocery store. He fills his shopping cart with items totaling $46. At checkout he will have to pay 6% sales tax on all items in the cart. does he have enough money to buy everything in his cart? Explain

Answers

Sales tax =0.06 so if you’re adding that to 46 then you have to do 46x1.06 which gives you the answer to how much Nate spends in total. Then you should be able to answer the question.

You multiply .06 times 46 then add it to 46 and see what the total is. If it’s more than 50 he won’t have enough

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83

Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.

Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.

Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?

Answers

Answer:

92.5

Step-by-step explanation:

1 is actually the mean of the group that did study is 92.5

2 is the MAD 5.2.

3is there are ten scores that are within the one MAD of the mean.
