Let's solve this problem step by step.

1. First of all we have this equation:

3(x + 4y) + 5(2x - y)

2. Let's apply distributive property:

3x+12y + 10x - 5y

3. Let's order this expression according to the variables:

3x + 10x + 12y-5y

4. Let's sum equal terms:

13x + 7y

SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t
lara [203]

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

h= -16(t-1.5)(t+1)

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in h= -16(t-1.5)(t+1)

0= -16(t-1.5)(t+1)

Divide both sides by -16

\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}

\frac{0}{-16} =(t-1.5)(t+1)

0 =(t-1.5)(t+1)

(t-1.5)(t+1)=0

Split

t - 1.5 = 0 or t + 1 = 0

Solve for t

t = 1.5 or t = -1

But time (t) can not be negative.

So:

t = 1.5

Hence, the diver will hit the water at 1.5 seconds

Cuantos múltiplos de 9 hay entre 60 y 100
slega [8]

Answer: 5 multiples of 9

Step-by-step explanation:

First take the difference between 100 and 60.

100-60=40

Then divide the difference by 9.

40/9=4.44

4.44 rounded up is 5 ==> 5 multiples of 9

Primero toma la diferencia entre 100 y 60.

100-60=40

Luego divide la diferencia entre 9.

40/9=4,44

4.44 redondeado es 5 ==> 5 múltiplos de 9
