1. The combined volume of all the tanks at the aquarium is written in Scientific notation. Keeping this on mind, you can write it as following:

(1.25)(10^{6})=1,250,000gallons

2. Now, you must sum the combined volume of all the tanks and the volume of  the new tank to calculate the total volume of all of them:Vt=1,250,000gallons+250,000gallons\\Vt= 1,500,000gallons

3. Now, you can write the result in Scientific notation, as following:

Vt=(1.5)(10^{6}) gallons

The answer is: (1.5)(10^{6}) gallons

X=17-4y<br> y=x-2<br> answer by substitution
sashaice [31]

Answer:

x=5,y=3

Step-by-step explanation:

the first step is to decide whether you want to substitute y and find x, or substitute x and find y.

(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).

for example, let's substitute y into the first equation:

x=17-4*(x-2)

so now,we will organize the equation:

x+4x=17+8

5x=25/(÷5)

x=5

now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:

y=5-2

y=3

Answer:

The answer to your question is FJ = 18

Step-by-step explanation:

Data

FG = 30

FH = 12

HE = 8

JH ║GE

These triangles are similar, so we can use proportions to find the length of FJ.

                            \frac{FJ}{FH} = \frac{FG}{FH + HE}

Substitution

                          \frac{FJ}{12} = \frac{30}{12 + 8}

Simplification

                         \frac{FJ}{12} = \frac{30}{20}

Solve for FJ

                        FJ = 12 \frac{30}{20}

Result

                        FJ = 18

Y = (x + 9)(x-4)<br><br>Now we need to multiply our binomials​
MA_775_DIABLO [31]

Answer:

x^{2}+5x-36

Step-by-step explanation:

To multiply binomials there are 2 ways. F.O.I.L., or the box method.

I will use the box method, and I hope it helps you!

After looking at the picture, this is not the answer quite yet.

x^{2}+9x-4x\\-36

Subtract 4x from 9x.

9x-4x=5x

So, the answer will be x^{2}+5x-36
