Maggie = X
Brother = 2X-3 <--- 3 years younger than twice her age.
2x - 3 + x = 24 <--- the sum of their ages is 24
3x - 3 = 24
3x = 27
x = 9
Maggie is 9.
Brother is 2*9 - 3 = 18 - 3 = 15
Answer:
15

1 number in the ratio is 5 years
Simplify 18.03 – 3(12.7 + 8.06) ÷ 2.
Answer:
−13.11
Step-by-step explanation:
Simplify the expression.
− 13.11
Answer:
-13.11
Step-by-step explanation:
Remember: Please Excuse My Dear Aunt Sally (PEMDAS)
You use the parentheses first, so it is 18.03-3*(20.76)÷2
So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14
Then, you subtract from left to right, which gives you: -13.11

-1/3(9-24x)= 2x +3
a x=-1
b x=3/10
c x=-1
d x=-3/10
Answer:
First, you have to distribute the 1/3. To do this, you can either multiply everything in the parentheses by 1/3 or you can divide it all by 3. I will use the division method, so 24x/3 is 8x and -9/3 is -3, so now the expres

Consider a sequence given by the formula a n = a n -1 − 5, where a1 = 12 and n ≥ 2.
Create an explicit formula of the sequence. Use the explicit formula to find of the
sequence. Give your answer in the answer space.
a100
Answer:
a= n+6 n
Step-by-step explanation:
n=an−1−5
Step 1: Flip the equation.
an−6=n
Step 2: Add 6 to both sides.
an−6+6=n+6
an=n+6
Step 3: Divide both sides by n.
an n = n+6 n a= n+6 n
Over the course of a year, a tractor-trailer commutes 160,000 miles across America.
a. Assuming a trucker changes his tires every 40,000 miles, and that he starts with a brand new set of tires, how many sets of tires will he use in a year?
b. If the trucker changes the oil every 10,000 miles, and he starts the year with a fresh oil change, how many times will he change the oil in a year?
Answer:
a. 4 sets of tires in a year.
b. 17 times a year.
Step-by-step explanation:
a. I just divided 160,000 by 40,000 to get 4 sets a year.
b. I divided 160,000 by 10,000 and then added 1 to get 17 times a year. I added one because the problem said that the trucker changes the oil in the beginning of the year.
Amanda makes 3 biscuits in 2 minutes. How many biscuits can she make in 30 minutes?
Amanda makes 45 biscuits in 30 minutes which is determined by the ratio.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that Amanda makes 3 biscuits in 2 minutes.
Let the number of biscuits would be x
To determine the number of biscuits can she make in 30 minutes.
According to the given question, we can write the ratio as:
3 biscuits : 2 minutes = x biscuits : 30 minutes
⇒ 3 / 2 = x / 30
Apply the cross-multiplication operation
⇒ x = (30 × 3) / 2
Apply the multiplication operation
⇒ x = 90 / 2
Apply the division operation,
⇒ x = 45
Therefore, she makes 45 biscuits in 30 minutes.

Runner 3 does not get a head start. He runs 750 meters every 3 minutes. Write an equation to represent Runner 3’s distance y for x minutes.
A. y=3x+250
B. 750x+3
C. 250x+3
D. 250x
Answer:
I think it is D!
Step-by-step explanation:
I'm not exactly for sure so if I'm wrong I'm sorry! But when writing an equation they don't have + or - and my conclusion is if you divide 750 by 3 it equal out to be 250 per minute. But I'm not for sure:(

Suppose U = {1, 2 , 3, 4, 5} is the universal set and A = {1, 5}. What is A' ?
A. A' = {1, 2 , 3, 4, 5}
B. A' = {2 , 3, 4}
C. A' = {1, 2 , 3, 4}
D. A' = {2 , 3, 4, 5}
A will be equall to {2 3 4}
The value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.
What is a set theory?The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.
Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,
U = {1, 2, 3, 4, 5
A = {1,5}
A' = {2,3,4}
Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Answer: Hexagon goes on the left, regular hexagon goes on the left, regular pentagon goes on the left, isosceles triangle goes on the left, triangle goes on the left, and square goes on the left.
Step-by-step explanation: A hexagon has six sides and six angles. A regular pentagon has five sides and five angles. A regular hexagon has six sides and six angles. An isosceles triangle has three sides and three angles. A triangle has three sides and three angles. A square has four sides and four angles. Hexagon: the prefix hexa- means six. Regular pentagon: the prefix penta- means five. Regular hexagon: the prefix hexa- means six. Isosceles triangle: the word tri-angle literally means three-angle, and all triangles have three sides. Triangle: the word tri-angle literally means three-angle, and all triangles have three sides. Square: a square is a Quadrilateral, which means it has four sides and four angles.

Solve for G
9+3.5g=11-0.5g
G=_______
Answer:
g = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9+3.5g=11−0.5g
9+3.5g=11+−0.5g
3.5g+9=−0.5g+11
Step 2: Add 0.5g to both sides.
3.5g+9+0.5g=−0.5g+11+0.5g
4g+9=11
Step 3: Subtract 9 from both sides.
4g+9−9=11−9
4g=2
Step 4: Divide both sides by 4.
g= 1/2
