Help solve for r algebra

Mathematics
1 answer:
bija089 [108]4 years ago
6 0

Answer:

\frac{20}{7}

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

7r=4(5)

Simplify: 7r=20

Divide both sides of the equation by 7 to get: r=\frac{20}{7}

Carlos uses a 3-D printer that melts plastic to produce custom action figures. The growth shows the amount of plastic it melts O
IceJOKER [234]

Answer and Step-by-step explanation:

It be more than 2 ounces and less than 1.5 ounces

The amount of plastic that is melted in 5.7 minutes is 1.71

To find this, you would use the point on the graph. Divide both of those numbers by 4.

(4, 1.2)

4/4 = 1.

1.2/4 = 0.3.

So, for every minute, 0.3 of an ounce of plastic is melted.

We then multiply 0.3 by 5.7 to get 1.71.

Nataliya [291]

I’m pretty sure the answer is 160 because the rectangle on the top has a volume of 64(16 x 4) and the rectangle on the bottom has a volume of 96(2 x 4 x 12). Add those together and you get 160 cubed inches. Hope this helped :)

Andrej [43]

The value of x is 4.

Step-by-step explanation:

Consider a Rectangle ABCD

AB as Top

CD as Bottom

AB = -1 + 4x

CD = 3x + 3

To Find:

x = ?

Solution:

In a Rectangle ABCD

Opposite sides of rectangle congruent,

AB = CD

Top = Bottom

on substituting we get

-1+4x=3x+3\\\\4x-3x=3+1\\\\x=4\\\therefore x =4

The value of x is 4.
