Solve these multi step equations. Show your work. Justify each of your steps. 3(x-8)=10x+18
Answer:
The answer is x= -6
Step-by-step explanation:
3(x-8)=10x+18
3x-24=10x+18
3x-24=10x+18
Both side +24
3x=18+24+10x
Both side -10 x
3x-10x=42
-7x= 42
Both side divided by 7
x= -6
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Which equation models the cost for having Fernando clean a pool for x hours and how much will a 3-hour cleaning cost?
A. y=25x+15;90
B. y=(25+15)+x;43
C. y=15x+25;70
D. y=(25+15)x;120
Explanation:
Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".

what are the 2 reasons that the Louisiana purchase caused a debate in the usa
It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.

craig likes to collect records. last year he had 10 records in his collection. now he has 15 records. what is the percent increase of his collection?
Answer:
His collection increased in a 20%.
Step-by-step explanation:
If 100% represents 10 records, what percentage would be for 12 records?
x = 12 100% / 10 = 120%
So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

Step-by-step explanation:
10(p-7)=180 solve for p
Answer
The answer is p=25
Answer:
p = 25
Step-by-step explanation:
Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
~
First, divide 10 from both sides of the equation:
(10(p - 7))/10 = (180)/10
p - 7 = 180/10
p - 7 = 18
Next, add 7 to both sides of the equation:
p - 7 (+7) = 18 (+7)
p = 18 + 7
p = 25
25 is your answer for p.

Find the circumference of
A circle with a diameter
Of 13.2
Answer:
C= 41.45
Step-by-step explanation:
The circumference is given by C = 2[tex]\pi[/tex]r, since the diameter is 13.2 then the radius is half of that so r = 6.6
So C = 2(3.14) (6.6) =41.448
The measures of two angles are 2x⁰ and (3x + 20)⁰. What is the measure of each angle if x = 14?
A. 48⁰, 42⁰
B. 28⁰, 62⁰
C. 36⁰, 62⁰
D. 48⁰, 28⁰
Answer:
b 28 and 62
Step-by-step explanation:
X is equal to 14 so other angle is 2x which is.2multiplied to X which gives 28degrees
X is equal to 14 and the other.angle is 3xplus 20 so 3x is 42 plus 20 gives 62

he ratio of trucks to cars is 6 to 2. If there are a total of 24 trucks, how many cars are there?
Answer:8
Step-by-step explanation:
Truck:car
6:2 or simplified to 3:1, which means 3 trucks for every 1 car.
24 trucks divided by 3 gives you 8.
Answer:
8 cars
Step-by-step explanation:
Set up a proportion to model this situation. First, write and simplify the given proportion.
trucks to cars;
6 : 2
Simplify,
3 : 1
Assuming that the rate at which trucks and cars are present in the parking lot is constant, one can make the expression,
trucks : cars
3 : 1 = 24 : x
Where (x) represents the unknown amount of cars. One can use cross products to solve this proportion,
3 : 1 = 24 : x
24 = 3x
Inverse operations,
24 = 3x
8 = x

8. Two coins are flipped. What is the probability that both of the coins land heads up?
Answer:
1/4
Step-by-step explanation:
1/2 x 1/2
Step-by-step explanation:
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
