Answers
Answer:
6
Step-by-step explanation:
first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.

-ilovejiminssi♡
a(8x + 7) = 4x + 3.5
8ax + 7a = 4x + 3.5
equating coefficients of x : 8a = 4 so a = 1/2
also 7a = 3.5 so a = 1/2
The value of a is 1/2

Part B:
Using the formula you wrote for Part A, what is the volume of Maria's new fish tank?
I'm giving out Brainliest!
Answers
Step-by-step explanation:
step 1. V = LWH. L = length. W = width. H = height.
step 2. V = (912)(312)(612) = 174,140,928 in^3.
The volume of Maria's new fish tank is 174,140,928 cubic inch.
It is required to find the volume of Maria's new fish tank.
What is cuboid?In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.
Given :
Maria has a new fish tank for her goldfish.
The fish tank is in the shape of cuboid.
length=912 inches
width=312 inches
Height=612 inches
Part A
The formula of volume of her new fish tank
Volume=length ×width × height.
Part B
Volume=length ×width × height.
By the use of formula we have,
V = (912) ×(312) ×(612)
V= 174,140,928 cubic inch.
Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

Sonya infers that, on average, most seventh graders use the Internet a little more than 7 hours each week. Based on the dot plot, which number is the median of Sonya's data?

Hope that his helps you :-)
The median and mean of the data is 7.5
What is Arithmetic Mean?The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.
Given:
According to box plot the mean is
= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26
= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26
= 195 / 26
= 7.5
Hence, the mean is 7.5.
Also, the median = (7+8)/2 = 7.5

The statements that are true are;

Step-by-step explanation:
Given that function 1 has the table;

5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.

Answers
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog

Create an equation modeling the scenario. Use the equation to solve for the missing number. In your final answer, include the equation and all necessary calculations. Twice the sum of a number and seven is three times the number.
Answers
Answer:
2(n+7)=3n
Step-by-step explanation:
"A number" is unknown so just create a variable in this case I made it "n."
We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.
