Let side B = X

Then side A = 2x

Side C = 2x +1

Mow you have x + 2x + 2x+1 = 76

Simplify:

5x +1 = 76

Subtract 1 from both sides:

5x = 75

divide both sides by 5:

x = 75 /5

x = 15

Side A = 2x = 2*15 = 30 cm

Side B = x = 15 cm

Side C = 2x +1 = 2*15 +1 = 30+1 = 31 cm

For the situation, write and solve an equation. Then, explain what your solution means. If you get stuck, try drawing a diagram
Bess [88]

Answer:

5r + (5 x 6) = 84

looking for rice per pound.

Step-by-step explanation:

5r + (5 x 6)  = 84

This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.

5r + (5 x 6)  = 84

5r + (30)  = 84

5r = 84-30

5r = 54/5

r  = 10 4/5  

r  =  10.8 pounds

What is the point-slope form of a line with slope -5 that contains the point (2, -1)?
Arisa [49]
Point slope formula: 
y-y_1=m(x-x_1)
We know that:
y1=-1
x1=2
m=-5 
So we plug those into the formula
y-(-1)=-5(x-2)
negative + negative= positive so.. 
Final answer:
<span>y+1=-5(x-2)</span>

A solid aluminum cube has sides each of length l . A second cube of the same material has sides four times the length of the fir
timofeeve [1]
The formula to find the volume of cube

cube = s^3

Therefore volume is equal to I^3

The second cube has 4x the First cube

4 × (I^3) = 4 ×I^3

Total volume of the second cube= 4I^3 cm3

Fact: the density(mass ÷ volume) of aluminium is 2.40g/cm3

Making mass the subject of the formula:

D = M ÷ V
(Times volume to remove deno minator)

Mass = Density × Volume

Mass = 2.40 × 4I ^3

Mass = 8.40I^3

By physics

weight= m × g

where
M = mass
g = acceleration due to gravity (= 9.8)

W = 8.40 I^3 × 9.8

Weight of aluminium = 82.32I^3
