Answer:

-1/2x-2

Step-by-step explanation:

Distribute the negative sign from the right side to make the equation positive

1/4x - 7 + (-1)(3/4x) + (-1)(-5)

(basically multiplying -1 to 3/4x and -5 to eliminate it)

1/4x - 7 + -3/4x+ 5

Make the equation similar

(1/4x + -3/4x) + (-7 + 5)

combine like terms

1/4x + -3/4x = -2/4x --> Simplifies to -1/2x

Do the other integers

-7 + 5 = -2

Put it together

-1/2x-2

the division problem is 7 divided by 15. this can be written as 7/15. to do this, you first know that 15 doesn't go into 7, so you add a decimal point, and make the 7 70. 15 goes into 70 4 times. 15 times 4 is 60. 70-60 is 10. 15 doesn't go into 10, so you add another 0 and bring it down. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. 15 doesn't go into 10, so you bring down another 0. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. at this point, you can probably guess that the 6 will go on for a while. this means it is repeating. this means your answer is "a".

pia is planting flowers. The number of tulips she plants is 4 more than half the number of daisies

Answers

It’s number A because it shows the number of tulips she plants is 4 more than half of the number of daises

The expression that represents the number of tulips Pia planted is option A. x/2 + 4.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

 

Given that,

Number of daisies planted is represented by x.

Number of tulips planted is 4 more than half the number of daisies.

Half the number of daisies is x/2.

4 more than half the number of daisies is x/2 + 4.

Hence the number of tulips planted is given by the expression x/2 + 4.

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?

Answers

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120

A tortoise moves at a speed of 26 inches in 9 seconds. What is its average speed in feet per hour?
≈ 780 ft/h
≈ 867 ft/h
≈ 855 ft/h
≈ 936 ft/h

Answers

Answer:

867 ft/h

Step-by-step explanation:

26 inches = 2.17 feet

9 seconds = 0.15 of a minute = 0.0025 of an hour

2.17 / 0.0025 = 867

867 ft/h
EXPLANATION
26 in=2.17ft
9 sec = 0.0025 hr
2.17/0.0025 = 867

which expression means “6 more than the quotient of a number and 5”

Answers

The answer is B because I did the the test you are doing

x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.

Here,

The expression that means "6 more than the quotient of a number and 5" can be written as:

(x / 5) + 6

In this expression, "x" represents the unknown number.

Let's break down the expression and explain it step by step:

(x / 5):

This part of the expression represents the quotient of "x" and 5.

It means that we divide "x" by 5.

(x / 5) + 6:

his means we take the quotient obtained in step 1 and add 6 to it.

It represents "6 more than the quotient of a number and 5."

Hence, x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.
