This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.

15.37
× 5
---------
76.85

15.37 times 5 is 76.85

Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85

I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?

Hey, there!

In order to solve decimals you should LINE them up.

15.37
× 5
_____
76.85

That means, "76.85" would be your result

I couldn't show you how I fully got my answer because I am on my laptop..

(2x-6)(x +11)<br> What is the answer?

ycow [4]

Answer:

2x^2+16x-66

Step-by-step explanation:

Use FOIL (First, Outside, Inside, Last)

(2x-6)(x+11)

F- 2x*x=2x^2

O-2x*11=22x

I--6*x=-6x

L--6*11=-66

2x^2+22x-6x-66

Combine like terms

2x^2+16x-66

Which situation represents a proportional relationship?

Natalka [10]

Answer:

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y=kx$

The ratio between the two variables is a constant called constant of proportionality k

$k=y/x$

<u><em>Verify each case</em></u>

A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

$\frac{4}{12}=\frac{9}{25}$

Multiply in cross

$4(25)=9(12)\\100\neq108$

Is not true

therefore

The situation not represent a proportional relationship

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

$\frac{5}{25}=\frac{8}{40}$

Multiply in cross

$5(40)=8(25)\\200=200$

Is true

therefore

The situation represent a proportional relationship

C) Larry packed 24 apples in 6 boxes and 46 apples in 9 boxes

$\frac{24}{6}=\frac{46}{9}$

Multiply in cross

$24(9)=46(6)\\216\neq276$

Is not true

therefore

The situation not represent a proportional relationship

D) Allie put 14 pieces of candy in 2 bags and 30 pieces of candy in 4 bags

$\frac{14}{2}=\frac{30}{4}$

Multiply in cross

$14(4)=30(2)\\56\neq60$

Is not true

therefore

The situation not represent a proportional relationship

What is the simplified form of the following expression? (5 points)

jek_recluse [69]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Simplify ⇨ (n⁵)(n²)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\tt \: ( n ^ { 5 } ) ( n ^ { 2 } )$

To multiply powers of the same base, add their exponents.

$\tt \: n ^{5 + 2} \\$

Add 5 and 2 to get 7.

$= \boxed {\boxed{\bf \: {n}^{7} }}$

The first option <em><u>n⁷</u></em><em><u> </u></em>is the correct answer.
