The formula of a volume of a cuboid:

$V=lwh$

l - length

w - width

h - height

We have:

l = (x + 4) cm

w = (x + 1) cm

h = 3 cm

Substitute:

$V=(x+4)(x+1)(3)$ <em>use distributive property</em>

$V=(x+4)(3x+3)$

$V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)$

$V=3x^2+3x+12x+12$ <em>combine like terms</em>

$\boxed{V=3x^2+15x+12}$

2x=160, can you help me with this, and show steps?

Mars2501 [29]

Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80

What is the solution to the proportion 3/5=x/10

Savatey [412]

x is 6.

3 / 5 = 6 / 10

Where 10 / 5 = 2 then 2 * 3 = 6.

6 / 10 simplified by dividing both numerator and denominator by 2 will result to 3 / 5.

A student bought a juice pouch forn$2.50 and 3 bags of chips. The total cost was $5.05.Write and solve an equation to determine

Oksana_A [137]

Answer:

The cost of a bag of chips is $c=\$0.85$

Step-by-step explanation:

Let

c ----> the cost of a bag of chips

we know that

The cost of a juice pouch ($2.50) plus the cost of 3 bags of chips must be equal to $5.05

The cost of 3 bags of chips is equal to multiply 3 by its cost c

The linear equation that represent this situation is

$2.50+3c=5.05$

solve for c

Subtract 2.50 both sides

$3c=5.05-2.50$

$3c=2.55$

Divide by 3 both sides

$c=2.55/3$

$c=\$0.85$
