solve for x
a) 2
b) 8
c) -2
d) -8

Answer:

x = 9 3/13 cm

Step-by-step explanation:

area = (length)( width)

20 cm² = (x)(2 1/6 cm)

x = 20 cm²/2 1/6 cm = (20)/(13/6) = (20)(6/13)

x = 9 3/13 cm

Area = 20 cm²

Breadth = 13÷6

Length = x

Area = l × b

20 = l × 13÷6

Therefore: l = 20 × 6 ÷ 13

                 l = 9 3/13

Therefore x in the figure = 9 3/13

Answer/Step-by-step explanation:

How many total fish is Dr. Howser planning on buying?

BOTH tanks hold 120 gallons

Tank A :

3 every 10 --> 120/10 ---> 12

So multiply 3 and 12 ----> 36

36 fishes in tank A

Tank B:

6 every 40 -----> 120/40 ----> 3

So multiply 6 by 3 ----> 18

18 fishes are held in tank B

Add them together:

18 + 36 ----> 54

ANSWER : Dr. Howser is planing on purchesing 54  fish all together.

What will be the ratio of the number of small fish he buys to the number of large fish that he buys

Small --->  36 fish

Large ---> 18 fish  

Small : Large  ----> 36:18

ANSWER: 36:18

Answer:

17a - 16

7b

Step-by-step explanation:

Given the following expressions

3a+4(5a - 4)=

Expand

3a + 4(5a)- 4(4)

= 3a + 20a - 16

= 17a - 16

For the expression

5b -2(5a -b) + 10a

Expand

5b - 2(5a)-2(-b) + 10a

5b - 10a  + 2b + 10a

= 5b + 2b -10a + 10a

= 7b + 0

= 7b

Step-by-step explanation:

A pizza is in the shape of a circle.

Since the perimeter is 10 inches, we have to find the radius. This will be:

2πr = 10

πr = 10/2

πr = 5

3.14r = 5

r = 5/3.14

r = 1.5924

Area = πr²

= 3.14 × 1.5924²

= 7.96 inches

= 8 inches approximately

Answer:

(- 8, 8 )

Step-by-step explanation:

Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then

- 4x - 8 = 24 ( add 8 to both sides )

- 4x = 32 ( divide both sides by - 4 )

x = - 8

Thus solution is (- 8, 8 )

Answer:

Look at the image.

Step-by-step explanation:

If 12 is 24%, then half of the percent is the actual number.

36% = 18

24% = 12

18% = 9

22% = 11

18 + 12 + 9 + 11 = 50

Answer:

a. 30 student in all

b. 8 more people

c. 1/3

d. 3/10

Step-by-step explanation:

Answer:

A) the graph represents 30 students in total because 9+10+6+5=30

B) 8 students prefer action or comedy over drama or sci-fi because if you add action and comedy together you get 19 and if you add drama and sci-fi together you get 11 and if you subtract 19-11 you would get 8

C) 1/3 of the students prefer comedies because the denominator (The bottom number) would be the total amount of students, which is 30, and the numerator (the top number) would be the students who like comedy, which is 10, so we put that into a fraction (10/30)- now both parts of the fractions are divisible by 10 so, 10 ÷ 10= 1 and 30 ÷ 10 = 3, so your final fraction would be 1/3

D) 3/10 of the students prefer action movies so we would do the same thing we did before for C, the total number of students in the denominator and the students who like action in the numerator to get 9/30, then 9 and 30 are divisible by 3 so 9÷3=3 and 30÷3=10 to get 3/10

Answer:

5

Step-by-step explanation:

We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.

This implies that she divide the garden was divided into 20 parts.

To determine the fewer number of parts she can divide her garden into, simply ⁸/20.

Thus:

8/20 = (2*4)/(5*4)

= ²/5 (4 cancels out 4)

Therefore, this implies that the least number of parts she can divide her garden into is 5.
