Answer:

The expression could be written as:  3L-5.

Step-by-step explanation:

We are asked to find an variable equation/ expresssion for the following world problem:

" Five less than three times the length L".

for this we have to firstly take '3' times the length 'L' (i.e. 3L) and then subtract that expression by 5 to make it five less than three times the length 'L' and hence obtain our required expression.

Hence, the expression is represented as: 3L-5

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

Sarah received $55 for her birthday. She used some of that money to buy 3 shirts priced at m dollars each.

jolli1 [7]

Answer:

$55 - 3m$

Step-by-step explanation:

Sarah has $55

Her expenses are 3 shirts priced at $m each.

Total cost of 3 shirts at $m each would be the multiplication of each:

3 * m = 3m

The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:

Remaining Money = 55 - 3m

Starks sculpture 30 cubed is a cube with sides 30 inches long. Whats its volume

Zolol [24]

Answer: $27000\text{ cubic inches}$

Step-by-step explanation:

Given : Starks sculpture 30 cubed is a cube with sides 30 inches long.

We know that the volume of a cube is given by :-

$\text{Volume}=(side)^3$

Then , the volume of Starks sculpture 30 cubed will be :

$\text{Volume}=(30)^3\text{ cubic inches}$

$\text{Volume}=30\times30\times30\text{ cubic inches}$

$\text{Volume}=27000\text{ cubic inches}$

Hence, the required volume = $27000\text{ cubic inches}$
