What is the answer to 4x-5x+9=5x-9?
fiasKO [112]

Answer:

x=3

Step-by-step explanation:

First, combine like terms on the left side

4x-5x+9=5x-9

-x+9=5x-9

Subtract 9 on both sides

-x=5x-18

Subtract 5x on both sides

-6x= -18

Divide by -6 on both sides

x=3

Hope this helps! :)

Algebra work need help<br> please show working
Nastasia [14]

Expand the left side:

(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2

Then a = 15 and b = 13, so a - b = 2.

What is the volume of a cone-shaped popcorn cup that is 8 inches tall and 6 inches across at the base?
Alina [70]

The volume of cone shaped popcorn cup is 75.36 cubic inches.

According to the given question.

The height of the popcorn cup = 8inches

And the diameter of the cup = 6 inches

⇒ Radius of the popcorn cup = 6/2 = 3 inches

As we know that, the volume of cone is calculated by the formula

volume of cone = (πr^2h)/3

Therefore, the volume of cone shaped popcorn cup

= 3.14((3)^2)(8)/3

= 3.14(3)(8)

= 75.36 cubic inches

Hence, the volume of cone shaped popcorn cup is 75.36 cubic inches.

A first alloy contains x pounds of 55% silver. It is mixed with a second alloy containing 30% silver to make 60 pounds of an all
Ann [662]

Answer:

"24 pounds" is the appropriate answer.

Step-by-step explanation:

According to the question, the equation will be:

⇒ x+y=60...(equation 1)

or,

⇒ \frac{55}{100}x+\frac{30}{100}y=\frac{40}{100}\times 60

      55x+30y=2400...(equation 2)

Now,

By multiplying (equation 1) by 55 and (equation 2) by 1, we get

⇒ 55x+55y=3300...(equation 3)

⇒ 55x+30y=2400...(equation 4)

From equation 3 and 4, we get

⇒ 25y=900

       y=\frac{900}{25}

          =36

By putting the values of "y" in equation 1, we get

⇒ x=60-36

       =24

Thus the value of x be "24 pounds".
