Answer:

perimeter = 9x + 4

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides.

perimeter = 2x + 3x - 1 + 4x + 5

Collect like terms.

The sum of two consecutive odd integers is 128. find the two integers.
Basile [38]
 <span>Call the first odd number x. 
That means the next odd number would be x+2. 
For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay? 

So then, x+x+2=128 
2x+2=128 
2x=126 
x=63 
x+2=65 
Thus, the two consecutive odd numbers are 63 and 65. 

Hope I helped :)</span>

 Amy​'s car holds at most 19 gallons of gas. Now it has 9 gallons. Use pencil and paper. Explain how to find the amount of gas s
Kazeer [188]

Answer:

10 gallons

Step-by-step explanation:

Amy​'s car's maximum capacity to hold gas = 19 gallons

present amount of gas  = 9 gallons

As the car's capacity is 19 gallons and present amount in tank is 9 gallons, so we can fill it as much as so that the amount in tank becomes 19 gallons.

let assume she fills x gallons

then x gallons and 9 gallons present earlier should be equal to 19 gallon, as the tank can not hold more than that.

lets write it mathematically

x + 9 = 19

subtracting 9 from both side

x + 9 - 9 = 19 - 9

=> x = 10

Thus, 10 gallons of gas is needed to fill the gas tank.

Find the sum of QR<br> 4x+33
12345 [234]

Answer:

Step-by-step explanation:

Simplifying

4x + 5 = 33

Reorder the terms:

5 + 4x = 33

Solving

5 + 4x = 33

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + 4x = 33 + -5

Combine like terms: 5 + -5 = 0

0 + 4x = 33 + -5

4x = 33 + -5

Combine like terms: 33 + -5 = 28

4x = 28

Divide each side by '4'.

x = 7

Simplifying

x = 7
