Answer:
I don't know the options, but you would find the lowest common denominator as possible, in this case it's 40. so, you figure out how you get from the original denominator to the common one, and then do the exact same thing to the numerators.
[tex]\frac{5}{8} =\frac{25}{40}[/tex] and [tex]\frac{3}{10} = \frac{12}{40}[/tex]
and then take the two new fractions and subtract the numerators to get what the answer is:
[tex]\frac{25}{40} - \frac{12}{40} = \frac{13}{40}[/tex]= 0.325
normally you would simplify, but this fraction is already in it's simplest form. so you could convert to a decimal, but only if the directions say to.
please help me, it would rlly be appreciated <3

Domain
We see from the graph that our x-values span from -3 to 2. Since both are closed dots, they are inclusive:
[-3, 2] or -3 ≤ x ≤ 2
Range
We see from the graph that our y-values span from -2 to 4. Since both are closed dots, they are inclusive:

Solve the following problems. Remember that all reasoning must be explained, and all steps of math work must be shown!
Answer:
see below
Step-by-step explanation:
1) Length of side OQ can be solved by using Pythagorean
OQ² = 3² + 4²
= √25
= 5
2) Length of side PQ can be solved by using Pythagorean
13² = 5² + PQ²
PQ² = 13² - 5²
= √144
= 12
3) Length of side RS and SQ can be solved by using Pythagorean
RS² = 13² - 6²
= √133
= 11.5
SQ² = 8² - 6²
= √28
= 5.3

Answer:
OQ = 5.0PQ = 12.0RS = 11.5, SQ = 5.3Step-by-step explanation:
A tangent meets the radius at right angles at the point of tangency. The triangles here are all right triangles, so the Pythagorean theorem can be used to find the missing side lengths.
__
1. a² = 3² +4² = 25
a = √25 = 5 = OQ
__
2. 5² +a² = 13²
a² = 13² -5² = 144
a = √144 = 12 = PQ
__
3. a = √(13² -6²) = √133 ≈ 11.5 = RS
b = √(8² -6²) = √28 ≈ 5.3 = SQ

A county fair has different ticket prices for adults and children. The expression 6a + 5c represents the total cost in dollars of tickets for a adults and c children.
The Patel family spends $38 on tickets. How many adult tickets and child tickets do they buy?
Already solved, okay then. T4TP.
The no. of adults and children in Patel's family is 3 and 4 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, A county fair has different ticket prices for adults and children.
The expression 6a + 5c represents the total cost in dollars of tickets for 'a' adults and 'c' children.
The Patel family spends $38 on tickets, which is,
6a + 5c = 38.
Now no. of adults and children which is a ≥ 0 and c ≥ 0 whole numbers.
So, 6×3 = 18 is, and 5×4 = 10 sums to 38 and satisfies our equation.
So, In Patel's family, there are 3 adults and 4 children.

What is the value of n in the equation - {(2n + 4) + 6 = -9 +4(2n + 1)
Answer:
n = 2.5 or n = (5/2)
Step-by-step explanation:
(2n+4) +6 = -9 + 4(2n+1)
first distribute the 4 to the (2n+1)
(2n+4) +6 = -9 + (8n+4)
then add 9 to both sides to cancel out the -9 on the right side
(2n+4) +15 = (8n+4)
next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract
15 = 6n
then divide 15 by 6 to get your final answer
n = 2.5
or
n = (5/2)
Solve for x: 0.75x + 3 = 6 (x - 3
I need to show my work
Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75x+3=6(x−3)
0.75x+3=(6)(x)+(6)(−3)(Distribute)
0.75x+3=6x+−18
0.75x+3=6x−18
Step 2: Subtract 6x from both sides.
0.75x+3−6x=6x−18−6x
−5.25x+3=−18
Step 3: Subtract 3 from both sides.
−5.25x+3−3=−18−3
−5.25x=−21
Step 4: Divide both sides by -5.25.
−5.25x/-5.25 = -21/-5.25
Answer: x=4
The value of x from the given equation is 4.
The given equation is 0.75x + 3 = 6 (x - 3).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solve for x as follows:
0.75x + 3 = 6x - 18
⇒ 6x-0.75x = 3+18
⇒ 5.25x=21
⇒ x=21/5.25
⇒ x=4
Therefore, the value of x from the given equation is 4.

Answer:
There were 48 ounces of milk left
Step-by-step explanation:
∵ Lessils used 25% of half a gallon of milk
→ Assume that the total amount of the milk is 25%
∴ The amount of milk left = 100% - 25% = 75%
∵ Half gallon = 64 ounces
→ That means the amount of milk left is 75% of 64 ounces
∴ The amount of milk left = 75% × 64
→ Divide 75% by 100 to change it to decimal
∵ 75% = 75 ÷ 100 = 0.75
∴ The amount of milk left = 0.75 × 64
∴ The amount of milk left = 48 ounces
∴ There were 48 ounces of milk left

The student council held a car wash to raise 200$ for the childrens hospital. In the first hour, they washed 2 cars. Each hour after that, the number of cars they washed increased by 2. How many cars did they wash by the end of 6 hours.
Answer:
Number of cars washed at the 6th hour = 12 cars
Sum of all cars washed in 6 hours = 42 cars
Step-by-step explanation:
First term, a = 2 cars
Common difference, d = 2 cars
6th term = a + 5d
= 2 + 5(2)
= 2 + 10
= 12 cars
Sum of the 6th term = n/2{2a + (n-1) d}
= 6/2{2*2 + (6-1)2}
= 3{4 + (5)2}
= 3{4 + 10}
=3(14)
= 42 cars

Write the standard form of the equation y−6=3/4(x−5).
9514 1404 393
Answer:
3x -4y = -9
Step-by-step explanation:
Multiply by 4 to clear the fraction.
4(y -6) = 3(x -5)
Subtract the left-side term to get variables on the same side, with a positive x-coefficient.
0 = 3(x -5) -4(y -6)
Eliminate parentheses and collect terms.
0 = 3x -15 -4y +24
0 = 3x -4y +9
Subtract 9 and swap sides to get standard form.
3x -4y = -9
