The ages of John and Sam are 47.34 and 17.66 years respectively.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.
Let, The age of Sam be 'x'.
Therefore, 2x + 12 + x = 65.
3x = 53.
x = 17.66.
So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.

There are 15 sedans on a used car lot, along with 54 other vehicles.
What is the probability that a randomly selected vehicle will be a sedan?
Write your answer as a fraction or whole number.
Answer:
5/23
Step-by-step explanation:
54+15=69
15/69=5/23
The Probability of selecting a sedan is 22%.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The degree to which something is likely to happen is basically what probability means.
Given that there are 15 sedans and 54 other vehicles, the total number of vehicles on the lot is:
Total number of vehicles
= Number of sedans + Number of other vehicles
= 15 + 54
= 69
So, the Probability of selecting a sedan
= Number of sedans / Total number of vehicles
= 15 / 69
= 5/23
= 0.22
= 22%

Carmela mixes 3/4 kilograms of walnuts, 1/2 kilograms of almonds,and 1/4 kilograms of pecans together. She divides the mixed nuts into 3/10 kilogram bags. How many bags of mixed nuts does she have. PLEASE HELP DUE TOMORROW.
Answer:
5 bags of mixed nuts.
Step-by-step explanation:
First, we add the amount of nuts together.
3/4 + 1/4 = 1
1 + 1/2 = 1 1/2
1 1/2 = 3/2 as an improper fraction.
Then we divide 3/2 by 3/10
To divide fractions, use "Keep, Switch, Flip"
Keep the first number, switch the sign, and flip the second fraction.

shown below. For which flowerbeds does Eric have enough fencing? Color in all the
possible answers.
A.
length = 30 yards
area = 300 square yards
B.
length = 20 yards
width = 5 yards
C.
width = 12 yards
perimeter = 48 yards
D.
length = 26 yards
width = 22 yards
E.
length = 16 yards
width = 14 yards
F.
width = 9 yards
area = 162 square yard
Answer:
Step-by-step explanation:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B
(20 + 5) ·2 = 25 · 2 = 50 yd (ok)
C
perimeter is 48 yd (ok)
D
(22 +26) · 2 = 48 · 2 = 96 yd (no)
E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)
F
length = 162 : 9 = 18 yd
(18 +9) · 2 = 27 · 2 = 54 yd (ok)
Answer:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B

E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)

2 distributed to each term inside 2(m + 2) looks like this:
2m + 4
first multiply 2xm, then 2x2

Step-by-step explanation:
Dan is cutting 4.75-foot lengths of twine from a 249-foot spool of twine. He needs to cut 42 lengths and says that 40.5 feet of twine will remain. Show that this is reasonable.
To show that Dan's statement is reasonable, we can set up an equation to represent the situation. Let's let x represent the number of feet of twine that Dan has cut.
We can then set up the following equation: [tex]4.75x = 249 - 40.5[/tex]
Solving for x, we find that x = 42. This means that Dan has cut 42 lengths of twine, which is what he said he would do.
Since the number of lengths of twine that Dan has cut and the amount of twine that will remain match what Dan said, his statement is reasonable.

Describe a math tool you could use to determine if a relation is a function. Explain how you would use it. Select all that apply.
Multiple select question
A)
I could use a mapping diagram. If more than one arrow points from an input value to the output values, I know it is not a function.
B)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held vertically, I know it is not a function.
C)
I could use a table. If I see that there is more than one output for an input, then the relation is a function.
D)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held horizontally, I know it is not a function.
E)
I could use a mapping diagram. If more than one arrow points from an output value to the input values, I know it is not a function.
Answer:
C, Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
