Simplifying
5y + 4 = 4y + 5

Reorder the terms:
4 + 5y = 4y + 5

Reorder the terms:
4 + 5y = 5 + 4y

Solving
4 + 5y = 5 + 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.
4 + 5y + -4y = 5 + 4y + -4y

Combine like terms: 5y + -4y = 1y
4 + 1y = 5 + 4y + -4y

Combine like terms: 4y + -4y = 0
4 + 1y = 5 + 0
4 + 1y = 5

Add '-4' to each side of the equation.
4 + -4 + 1y = 5 + -4

Combine like terms: 4 + -4 = 0
0 + 1y = 5 + -4
1y = 5 + -4

Combine like terms: 5 + -4 = 1
1y = 1

Divide each side by '1'.
y = 1

Simplifying
y = 1

A 3-gallon tub of ice cream yields about 90 scoops of ice cream. There are roughly 3785 cubic centimeters in 1 gallon. Determine
ASHA 777 [7]

Answer:

The radius of the scoop is r = 3.1 cm

Step-by-step explanation:

Since 3 gallons yields 90 scoops, and 1 gallon = 3785 cm³.

3 gallons = 3 × 3785 cm³ =  11355 cm³

So we have 11355 cm³ in 3 gallons which is also the volume of 90 scoops.

Since 90 scoops = 11355 cm³, then

1 scoop = 11355 cm³/90 = 126.2 cm³

Now, if each scoop is a sphere, the volume is given by V = 4πr³/3 where r is the radius of the scoop. Since we need to find the radius of the scoop, r, making r subject of the formula, we have

r = ∛(3V/4π)

Substituting V = 126.2 cm³, we have

r = ∛(3× 126.2 cm³/4π)

= ∛(378.6 cm³/12.57)

= ∛30.13 cm³

= 3.1 cm

So, the radius of the scoop is r = 3.1 cm

The length of a rectangle is 10 meters more than the width. If the perimeter is 184 meters, what are the length and the width?
Brilliant_brown [7]
Perimeter = (2 × Length) + (2 × Width)

If the length is dependent on the width (because the length is 10 more than the width), we can say that L = W + 10.

To find the answer to the Peri, we have to find out what the W is first.

184 = 2(W + 10) + 2W
184 = 2W + 20 + 2W
184 = 4W + 20
184 - 20 = 4W = 164
164 ÷ 4 = W
41 = W

We have found out width. Our length is W + 10, so L = 41 + 10 = 51

W = 41 and L = 51

What is the equation of a line that is parallel to −x+3y=6 and passes through the point (3, 5) ?
oksian1 [2.3K]
3y=6+x
y=(6+x)/3
y=2+x/3
y=mx+b
y=x/3+b
so m(slope) is 1/3
use the point (3, 5), sub this for x and y
5=3/3+b
5-1=b
b=4
therefore, y=x/3+4
or y=(1/3)x+4 (you can write it like this as well)
