What two numbers add up to 18 and multiply to 80
mestny [16]

Answer:

8 and 10

Step-by-step explanation:

First, let's look at the factors of 80.

1 • 80 = 80

2 • 40 = 80

4 • 20 = 80

5 • 16 = 80

8 • 10 = 80

Look at each pair and evaluate their sum.

1 • 80 = 80

  • 1 + 80 = 81

2 • 40 = 80

  • 2 + 40 = 42

4 • 20 = 80

  • 4 + 20 = 24

5 • 16 = 80

  • 5 + 16 = 21

8 • 10 = 80

  • 8 + 10 = 18

Our last pairing multiplies to 80 and adds up to 18. Therefore, your answer is 8 & 10.

Hope this helps!

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! :)

An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters abov
Hoochie [10]

Answer:

After 3 seconds

Step-by-step explanation:

Given

h(t) = -5t^2 + 14t + 3

Required

Time the drop will hit the ground

When the drop hits the ground,

h(t) = 0

So, we have:

0 = -5t^2 + 14t + 3

Rewrite as:

5t^2 - 14t - 3 = 0

Expand

5t^2 + t - 15t - 3 = 0

Factorize

t(5t + 1) -3(5t + 1) = 0

Factor out 5t + 1

(t -3)(5t + 1) = 0

Split

t -3 = 0 or 5t + 1 = 0

Solve for t

t = 3 or 5t = -1

Time cannot be negative.

So:

t = 3
