Which of the following is equivalent to 5 · (7 · 4)? *
A. 35
B. (5 · 7) · 4
C. 5 · (4 · 4)
D. 5 + (7 + 4)

Answers

Answer 1
B because you multiply 7 times 4 that’s 28 then times 5 that’s 140 so for b you do 5 times 7 that’s 35 then times 4 that’s 140 so b is the correct answer, hope it helps

what is the solution set to the inequality - 3x + 2 > 17

Answers

The answer would be x<-5

Explanation
You have to move 2 over to the 17 to get the x by itself so since it’s a positive 2, you would subtract 2 which would give you -3x>15. THEN you would divide the 15 by negative 3 which gives you -5 BUT since you are dividing by a negative you would flip the sign.

{y=6x+14
{2x-y=2



thanks bud lol

Answers

y = 6x + 14

2x - y = 2

so
2x - (6x + 14) = 2

2x -6x - 14 = 2

-4x - 14 = 2

-4x = 2+14

-4x = 16

x = -4

y = 6(-4) + 14

y = -24 + 14

y = -10

(x,y) = (-4,-10)

Find the measure of each acute angle.

Answers

(11x - 2) + (6x + 7) = 90

17x + 5 = 90

17x = 85

x = 5

11(5) - 2 = 55 - 2 = 53

6(5) + 7 = 30 + 7 = 37

53º and 37º

Hope this helps! :)

The measures of two acute angles are 53 degrees and 37 degrees.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

The given triangle is a right angle triangle.

The sum of two acute angles is equal to a right angle

(11x - 2) + (6x + 7) = 90

Add the variable terms and constants

17x + 5 = 90

Subtract 5 on both sides

17x = 85

Divide both sides by 17

x = 5

So 11(5) - 2 = 55 - 2 = 53

and 6(5) + 7 = 30 + 7 = 37

Hence, the measures of two acute angles are 53 degrees and 37 degrees.

The circle graph shows how Tremaine divided his time on the computer last week.

Tremaine used the computer a total of 30 hours last week. How many more hours did Tremaine use the computer to play games than to do research?

A. 1.5 hours

B. 20 hours

C. 6 hours

D. 7.5 hours

Answers

Answer:

A:1.5 hours

Step-by-step explanation:

all you have to do is figure out 5% of 30 which is 1.5

The required number of hours more, Tremaine uses the computer to play games than to do research is 6 hours.

What is the percentage?

The percentage is the ratio of the composition of significant value to the overall composition of significance value multiplied by 100.

Here,
As mentioned in the question Tremaine used the computer for a total of 30 hours last week.

So from the circle graph:
Hour spend on games = 25% of 30
                                  = 0.25 * 30

                                  = 7.5 hours

Hours spend on research = 5% of 30
                                        = 1.5 hours

Thus, the required number of hours more, Tremaine uses the computer to play games than to do research is 7.5 - 1.5 = 6 hours.
