Answer:
Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30
treat the inequality sign as an equal sign, that should help
The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?
A. Group A, because a child in the group has the least forearm length of 10 inches.
B. Group A, because four children have a forearm length longer than 12 inches.
C. Group B, because no child in the group has a forearm length longer than 12 inches.
D. Group B, because five children in the group have the least forearm length of 10 inches.

What is the surface area of the square pyramid?
6 square meters
16 square meters
28 square meters
49 square meters
Answer:
16 sq meters
Explanation
Surface area is the area of the figures combined. Find area of base and triangles then add.
2×2=4
2×3÷½=3
since there are 4 triangles you do 3×4
12+4= 16

Solve for x: 24 = -2(r + 9)
HELP
Answer:
r = -21
Step-by-step explanation:
-2(r + 9)
-2 (-21 + 9)
-21 + 9 = -12
-2(-12)
= 24
Answer:
-21
Step-by-step explanation:
Detailed explanation:
24 = -2(r + 9)
First, I did distributive property
24 = -2r -18
Now I will add 18 to both sides
42 = -2r
Now I will divide both sides by -2
-21 = r

Answer:
10,500
Step-by-step explanation:
See this as 2 rectangles: a box of water (28cm), and another box with the height you want (35cm)
Area of Rectangle = lwh
For the water;
50 x 30 x 28= 42000
As for the needed volume:
50 x 30 x 35 = 52500
To find how much more water, subtract the smaller volume from bigger volume.
10500 should be the final answer
One afternoon, Dillon and 3 friends visit the zoo. They split the cost of parking the car evenly. Then each person buys a ticket to enter the zoo. By the end of the afternoon, each person has also purchased 2 bottles of water.

3 x 7/12 do not simplify pls
Answer:
21/12 this is your answer.
Step-by-step explanation:
you add a 1 under the three to make it a fraction, then you multiply straight across 3 times 7 is 21 and 1 time 12 is 12. so you answer is 21/12.
the simplifyed answer is 7/4

How is finding the area of composite two-dimensional figures similar to finding the surface area of three-dimensional figures?
Answer:
If you find the area of a 2D shape (ex-square) you would multiply the area by the amount of faces with the shape (that are the same shape)
8th grade linear functions, will give brainliest if the steps are listed and explained :)))
Get the slope of the line using the two known points:
slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3
Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,
y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4
Then for some given value of x, the third point has y-coordinate 3x + 4.
"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.

Ahat is the area of this quadrilateral?
A,B,C,D
Answer:
A. 12 square feet
Step-by-step explanation:
So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.

22,064 ÷ 394 equals what?
Answer:
the correct answer is 56
Step-by-step explanation:
22064÷394=56
The solution is : 22,064 ÷ 394 equals 56.
Here, we have,
given that,
22,064 divided by 394
Given the following mathematical expression;
22,064 / 394
We would apply the law of division for fractions.
22,064 / 394
= 22,064 ÷ 394
= 56
the result of the division.
Hence, The solution is : 22,064 ÷ 394 equals 56.
