A.

x/7 + x/7 =4

Calculate the sum

2/7x=4

multiply both sides of the equation by 7/2

x=14

b. 2x/3 - x/3 =4

Multiply both sides of the equation by 3

2x-x=12

collect like terms

x=12

c. 4x/5 - 2x/5 =7

Multiply both sides of the equation by 5

4x-2x=35

Collect like terms

2x=35

Divide both sides of the equation by 2

x= 35/2

d. x/6 + x/4 =3

Multiply both sides of the equation by 12

2x+3x=36

Collect like terms

5x=36

Divide both sides by five

x = 36/5

e. -x/-5 + x/4 =2

Multiply both sides by 20

-4x+5x=40

Collect like terms

x=40

f. x/3 - x/6 = 5

Multiply both sides by six

2x-x=30

Collect like terms

x=30

hope this helps!!

What is the volume of a block of ice measuring 3 meters long, 1.5 meters wide, and 2 meters high? A. 900 cu. m B. 12 cu. m C. 9
lutik1710 [3]
To find volume of a rectangular prism, you simply need to multiply length times width times height. We know from the text that our block of ice is 3 meters long, 1.5 meters wide, and 2 meters high. So all we need to do is multiply:

3 * 1.5 = 4.5

4.5 * 2 = 9

The block of ice has a volume of 9 cubic meters.
Choice C is your correct answer.
Hope that helped! =)

What is the value of x? <br><br> Enter your answer in the box.<br><br> x =___
Zanzabum

Answer:

x = 12

Step-by-step explanation:

The diagram shows an equilateral triangle (because all angles are congruent). All sides in equilateral triangle are congruent, so

4x-10=5x-22=3x+2

Solve the equation

4x-10=5x-22\\ \\4x-10-4x=5x-22-4x\\ \\-10=x-22\\ \\-10+22=x-22+22\\ \\12=x

Check this value:

4x-10=4\cdot 12-10=48-10=38\ units \\ \\5x-22=5\cdot 12-22=60-22=38\ units\\ \\3x+2=3\cdot 12+2=36+2=38\ units

Thus, x=12

Find the midpoint between −18 and 52.
Mama L [17]
Finding the midpoint between two points on a line involves three steps:

1. Find the distance between the two points
2. Find half of that distance
3. Either add that half to the lowest point, or subtract it from the highest point.

To find the distance between 52 and -18, we can take the absolute value of their difference. The reason we take the absolute value is to force the sign to be positive, since distances can never be negative. -18 - 52 = -70, and |-70| = 70.

Second, we find half of that distance, which in this case would be 70/2 = 35.

Finally, we add that value to -18 to find a midpoint of -18 + 35 = 17.
