Pablo folds a straw into a triangle with side lengths of 4x2 – 3 inches, 4x2 – 2 inches, and 4x2 – 1 inches. The perimeter of the triangle is 12x2 – 6 inches. If x = 1.5, what was the length of the straw before it was folded?

Answers

The perimeter is the sum of the lengths of the traingle. So,
P = 12x2 - 6
Plugging in the given value of x,
P = 12 (1.5)^2 - 6
P = 21 inches

Assuming that the ends of the straw are not overlapping in forming the triangle, the perimeter is just equal to the original length of the straw.

7-3y=y-6(2+1/2y) how do I solve for y

Answers

-3y + 7 = y - 6(¹/₂y + 2)
-3y + 7 = y - 6(¹/₂y) - 6(2)
-3y + 7 = y - 3y - 12
-3y + 7 = -2y - 12
+ 3y + 3y
       7 = y - 12
      + 12     + 12
      19 = y

Step-by-step explanation:

a gasoline pump delivers 4 2/5 gallons of gas per minute. how many minutes will it take to fill a gas tank that holds 16 1/2 gallons?

Answers

The number of minutes will it take to fill a gas tank that holds $16(1)/(2)$ gallons is $3 (3)/(4)$ .

Given that, a gasoline pump delivers $4 (2)/(5)$ gallons of gas per minute.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

A gas tank that holds $16(1)/(2)$ gallons

Time taken to fill the gas tank

= $16(1)/(2) / 4(2)/(5)$

= 33/2 ÷ 22/5

= 33/2 × 5/22

= 3/2 × 5/2

= 15/4

= $3 (3)/(4)$

Therefore, the number of minutes will it take to fill a gas tank that holds $16(1)/(2)$ gallons is $3 (3)/(4)$ .
