Answer:

x+7=19-x

Move the x to the other side by adding it,

2x+7=19

Now move the 7 to the other side by subtracting it

2x=12

Lastly divide both sides by 2 to get x alone

x=6

The dictionary is 3 inches thick. What is the volume of the dictionary

Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

If the dictionary is a square ( all sides are equal ) the the volume is

V = Length * Length * Length = $L^{3}$

V = 3 * 3 * 3 = 27 $inch^{3}$

while if its rectangular ( all side are not equal ) shaped

V = Length * Width * Height (thickness)

V = L * W * 3 = 3LW $inch^{3}$

You can buy 3 pounds of strawberries for 3.99 at Kroger knowing this what is the unit rate per pound of strawberries and how muc

Varvara68 [4.7K]

Answer:

1.33 per pound
6.65 for 5 pounds

Step-by-step explanation:

To find cost per pound, divide cost by pounds.

3.99/(3 lb) = 1.33/lb . . . . cost per pound

The cost of 5 pounds will be found by multiplying that by 5:

(1.33/lb)(5 lb) = 6.65 . . . cost of 5 pounds

Leyla drops a penny from a height of 150 m.

gizmo_the_mogwai [7]

When the penny hits the ground, h will = 0.

So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m

Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.

We can use only the positive root, as we're measuring time.

t = 5.5 sec (answer)
