Step-by-step explanation:

Answer:

m = 0.28571428571

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29

Answer:

I know that 2 is 18

Answer:

Step-by-step explanation:

16 = - 4y - 12

Bringing like terms on one side

16 + 12 = - 4y

28 = - 4y

28/-4 = y

-7 = y

Answer:

3.675 × 10^18

Step-by-step explanation:

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

[tex]4\text{ quarts}=1\text{ gallon}[/tex]

[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]

[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]

Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.

Answer:

x= 13.5

Step-by-step explanation:

f(x) = 2x + 9

f(x) = 36

Set the 2 equations equal to each other;

2x + 9 = 36

Subtract 9 from both sides;

2x = 27

Divide both sides by 2;

x = 13.5

Check:

f(x) = 2x + 9

f(13.5) = 2(13.5) + 9= 27 + 9 = 36

Answer:

8/3=48/x

Step-by-step explanation:

times both sides by 3 8=144/x

times x by both sides 8x=144

x=18

there are 18 techers

Answer:

y= 2/5-1

Step-by-step explanation:

You get the 2/5 because you go 2 to the right and go 5 up, the -1 is because the x-int is at -1.

Answer:

red

Step-by-step explanation:

The complete question is as follows;

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts

Solution;

The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams

Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams

So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts

Answer:

1. f(n+1) = f(n) + 0.09

2. The correct answer is 403 = x. The student’s error is that she did not cancel out properly the constant by the inverse add ended to find the answer of the variable.

Answer:

Actually, it's C multiplication Cutty you can't be giving Wrong answers.

Step-by-step explanation:

It's C Multiplication because Were using the PEMDAS technique and this stands for

P- Parenthesis

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction

So if you see in the Pemdas technique It will be C Multiplication.

Answer:

Step-by-step explanation:

Given Katiyln and lewis share sweets in the ratio =7:1

katliyn gets= 21 sweets

share of katiyln sweet =7x

share of Lewis sweet =X

So 7x=21 given

X=21/7

X=3

So Lewis gets x =3 sweets.

Answer:

(30, 0) and (0, 50)

Step-by-step explanation:

( 0 , y ) are coordinates of y-intercept.

( x , 0 ) are coordinates of x-intercept.

25x + 15y = 750

25(0) + 15y = 750 ⇒ y = 50

( 0 , 50 ) are coordinates of y-intercept.

25x + 15(0) = 750 ⇒ x = 30

( 30 , 0 ) are coordinates of x-intercept.

Answer:

You have a rectangular pool 15 X 30 X 5 feet

The floor of the pool is 15X30 = 450 ft2

Two sides are 5X15 = 2(75) = 150 ft2

Two sides are 5X30 = 2(150) = 300 ft2

Total area to be painted: 900 ft2

(900 ft2)/(250 ft2/gal) = 3.6 gallons

Since we can't purchase .6 gallons we

must purchase 4 gallons of paint

The volume of the pool is 15X30X5 = 2250 ft3

1 ft3 = 7.48 gallons

2250(7.48) = 16,830 gallons of water

Answer: DE is 15 and AB is 6

Step-by-step explanation:

Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).

Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.

So, to find DE, just multiply the corresponding side, BC, by 300%.

5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?

For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.

Answer:

1. the perimeter of the first question is 22.5

2. true

5. 16.25

these are the only ones i remember how to do!

sorry :(

Hopefully someone fills in the rest of the answers!!!

Answer:

Question 1:

8/12 = 4/6 = 3/x

0.6 = 0.6 = 3/x

It is a similar triangle, therefore 3/x = 0.6

x = 5 because 3/5 = 0.6

Question 2

You did that correct :)

Question 3:

"Check all that apply"

B

D

Question 4

You got question 4 wrong since similar triangles have similar ratio.

8/10 = 8/10 = 10/14

0.8 = 0.8 = 0.7

Correct answer for question 4 is B("No they are not similar because the ratios are not equal")

Question 5

The Quadrilaterals are similar. Therefore:

22.4/14 = 12.8/8 = 12/7.5 = 26/x

1.6 = 1.6 = 1.6 = 26/x

Meaning 26/x = 1.6

x = 16.25

Because 26/16.25 = 1.6

Hope that helps :)

Step-by-step explanation:

Answer:

k = 3 + 6x

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]

Given

27 × [tex]9^{3x}[/tex]

= 3³ × [tex](3^{2}) ^{3x}[/tex]

= 3³ × [tex]3^{6x}[/tex]

= [tex]3^{3+6x}[/tex]

= [tex]3^{k}[/tex] → with k = 3 + 6x
