Two times the cost of a burger and fries is $10. If the fries are $1 how much is the burger?
Answer:
Step-by-step explanation:
b = cost of 1 burgerf = cost of fries$1 = the cost of fries2(b+f) = 10
2b + 2f = 10
2b + 2(1) = 10
2b + 2 = 10
- 2 - 2
2b = 8
/2 /2
b = $4 <== the cost of each burger
Check your answer:
2(b+f) = 10
2(4+1) = 10
8 + 2 = 10
10 = 10
This statement is correct

Answer:
390m^2
Step-by-step explanation:
The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area
a = 5m
b = 12m
c = 13m
L = 11m
First, we need to find the base area...
base area = (a*b)/2
(5*12)/2 = 30 m^2
Next, find the surface area
A = 11(5 + 12 +13) + 2*30 = 390 m^2

A 12-sided solid has faces numbered 1 to 12. The table shows the results of rolling the solid 200 times. Find the experimental probability of rolling a number less than 3 .
Answer:
3/20 or 0.15 or 15%
Step-by-step explanation:
The experimental probability is
amount of wanted outcomes/total amount of outcomes
Less than 3 is 1 and 2.
1= 14 times
2= 16 times.
Add, get 30.
30 is the amount of wanted outcomes, and the total is 200.
30/200 is either 3/20, 0.15, or 15%, because of different formats.

Answer:
Write the absolute value equations in the form
x−b
=c (where b is a number and c can be either number or an expression) that have the following solution sets.
Chapter Reference
a
Two solutions: x=2, x=14.
Step-by-step explanation:
The absolute value equations in the form |x-b|=c is 6.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Two solutions are x=2 and x=14
Now,
To write an absolute value equation that has these solutions, we need to find a common value of b and c that satisfy the property above. One possible way to do this is to find the midpoint and the distance between the two solutions. The midpoint is the average of the two solutions, and the distance is half of their difference. The midpoint will be the value of b, and the distance will be the value of c.
Using this method, we get:
b = (2 + 14) / 2 = 8
c = (14 - 2) / 2 = 6
Therefore, by the given equation the answer will be 6

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.
We know that;
The volume of prism is,
⇒ V = B × H
Where, B is the area of the base and h is the height of the prism.
Hence, We get;
The volume of prism is,
⇒ V = 12 × 3 × 3.5
⇒ V = 126 yards²
Thus, The volume of prism is,

The answer to number 4 would be 576cm^3
Step-by-step explanation:
Number 4:
The formula for volume would be V=B·h
to find B your going to find the base of the triangle which would be B=1/2·8·9 so B=36
Then you find the height which is 16 because it connects the two bases of the triangular prism
Next you multiply B·h so 36·16
Lastly, add your units and cube the number because you are foinding volume.

Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 37 times. The results are shown below:
A strawberry chew was selected 8 times.
A cherry chew was selected 12 times.
A watermelon chew was selected 17 times.
Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a decimal to the nearest hundredth.
Answer:
32.43%
Step-by-step explanation:
Since there are a total of 37 tests and cherry was selected 12 times, the probability would be 12/37.
12(100/37)
32.43
The probability that it will be a cherry or watermelon is; P(Cherry or water melon) = (12 + 17)/37 = 0.51
How to find the Probability?
We are told that Ryan performs the experiment a total of 37 times.
From the experiment he got;
Strawberry = 8 times
Cherry = 12 times
Watermelon = 17 times
Thus, probability that it will be a cherry or watermelon is;
P(Cherry or water melon) = (12 + 17)/37 = 0.51
