Answer:

18-Yes 19-No 20-yes 21- yes

Step-by-step explanation:

18

1 to 4, 5 to 20

Yes, this is correct

WE can multiply 1*5 and 4*5 to get 5 to 20

19

Wrong

3 to 11, 1 to 3 isn't correct

For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)

So, no

20

2/3 is 2 to 3

14/21 is 14 to 21

If we multiply 2*7 and 3*7, we get 14 to 21

21 25 to 30 is  equal to 35 to 42

They just added 7 to both numbers

if we divide ratio 1 by 5, we get 5:6

if we divide ratio 2 by 7 we get 5 to 6

Answer: 3

Step-by-step explanation: Figure B has side measures 16, 20, and 9. Figure A has side measures 48, 27, and 60. The ratio of each of the corresponding sides is 1:3 (16:48, etc). Therefore, the scale factor of Figure B to Figure A is 3.

Answer:

250%

Step-by-step explanation:

Hi there!

In order to solve this problem, we have to divide 200 by 80.

When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.

Now we have the 0.5

A half is equivalent to 50%, so we add those two percentages together to get 250%.

I hope this helps!

 - We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.

Equation at the end of Step 1:

 - We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.

Equation at the end of Step 2:

 - We do this because we need one number left over to get a simplified version of this equation.

Answer:

-10/9

Step-by-step explanation:

do y2-y1/x2-x1 to find it

Given:

[tex]f(x)=4x-7[/tex]

[tex]g(x)=4x[/tex]

To find:

The expression for f(f(x)).

Solution:

We need to find f(f(x)).

[tex]f(f(x))=f(4x-7)[/tex]                             [tex][\because f(x)=4x-7][/tex]

[tex]f(f(x))=4(4x-7)-7[/tex]                             [tex][\because f(x)=4x-7][/tex]

Using distributive property, we get

[tex]f(f(x))=4(4x)+4(-7)-7[/tex]

[tex]f(f(x))=16x-28-7[/tex]

[tex]f(f(x))=16x-35[/tex]

Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].

Answer:

2750 chocolates

Step-by-step explanation:

Find how much she has bought already:

1,125(2)

= 2,250

Then, subtract this from 5,000

5000 - 2250

= 2750

So, she still needs 2750

Answer:

2,750

Step-by-step explanation:

2 cases of 1,125 chocolates = 2,250 chocolates

5,000 - 2,250 = 2,750 more chocolates needed

(that's also 3 cases of chocolates needed :p)

Step-by-step explanation:

58+78=131

180-131=49

10(5)-1

=5

Answer:

x=5

Step-by-step explanation:

A triangle= 180

53+78+10x-1=180

Combine like terms

130+10x=180

Subtract by 130 on both sides

10x=50

Divide by 10 on both sides

x=5

Answer:

-10 1/2, -8 1/2, -4 1/2, 4 1/2

Step-by-step explanation:

Basically to get the answer, its easiest to convert the fraction to a decimal then put it on a number line. 1/2=0.5.

Answer:

-10 1/2, -8 1/2, -4 1/2, 4 1/2

Step-by-step explanation:

Something that helps is a number line, put 0 in the middle and put positive numbers on and negitive numbers so you can see what is smaller. For example:

least to greatest

4

Step-by-step explanation:

:)

Answer:

4

Step-by-step explanation:

Given that :

Total fraction of paint Carin has = 2/3 bottle

Fraction used to paint a model airplane = 1/6

Number of model. Airplanes 2/3 of a bottle could paint ;

Total fraction of paint / fraction used to paint a model airplane

(2/3) ÷ (1/6)

2/3 * 6/1

= 12 / 3

= 4 model airplanes

Answer:

Step-by-step explanation:

Answer:

[tex]x = 25[/tex]

Step-by-step explanation:

[tex](4x) + (5 + 3x) = 180[/tex]

[tex]4x + 5 + 3x = 180[/tex]

[tex]7x + 5 = 180[/tex]

[tex]7x = 180 - 5[/tex]

[tex]7x = 175[/tex]

[tex] \frac{7x}{7} = \frac{175}{7} [/tex]

[tex]x = \frac{175}{7} [/tex]

[tex]x = 25[/tex]

Answer:

4 * a  = 4

a = 1

b * 6

4 * 6

24b

2 a * 4 = 8

b * 5 = c *7

7 * 5 = 35

b = 17.5

C = 17.5

17.5+17.5 = 17.5 * 2 +4a+ b5

So your answer is 54a

Answer: Weight of sand in each bag = 3.17 lb.

Step-by-step explanation:

Given : Total weight of sand = 63.4 lb

Total small bags = 20

Weight of sand in each small bag = (Total weight of sand ) ÷ (Total bags)

Weight of sand in each small bag = ( 63.4) ÷ (20)

Weight of sand in each small bag = 3.17 lb

Hence, the weight of sand in each small bag = 3.17 lb.

Answer:

3.17lb
