How to solve 2-step equations
Answer/Step-by-step explanation:
1) First, add or subtract both sides of the linear equation by the same number.
2) Secondly, multiply or divide both sides of the linear equation by the same number.
3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.

write an equation that can be used to represent this situation?
Answer:
Step-by-step explanation:
You rent a 35 dollar jet ski and per hour plus a 20 dollar rental fee. Your bill came to 90 dollars.If 35 and 20 dollars equal to 55 that means you had payed something that was 1-35 dollars. 35 + 20 = 55
Darius sees a new store advertising 10 of the same packs of paper clips for $41.50. Which statement best describes the strategy Darius should use to get the best price for each pack?
Answer:
$4.150/packStep-by-step explanation:
Given the price of 10packs as $41.50, we can express it as;
10 packs = $41.50
To get the equivalent price of 1 pack, we will say;
1 pack = $x
Solving both equalities for x;
10 packs = $41.50
1 pack = $x
cross multiply
10 * x = 1 * 41.50
10x = 41.50
Divide both sides by 10
10x/10 = 41.50/10
x = 4.150
Hence the price for each pack is $4.150
Choose the statement that best describes a solution of a system of linear inequalities.(1 point)
A solution of a system of linear inequalities is an ordered pair that satisfies at least one of the inequalities in the system.
A solution of a system of linear inequalities is an ordered pair that satisfies the intersection of the border of each inequality.
A solution of a system of linear inequalities is an ordered pair that satisfies neither inequality in the system.
A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Answer: A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Step-by-step explanation:
A system of linear inequalities can be written as:
y < a*x + b
y < c*x + d
or
y ≤ a*x + b
y ≤ c*x + d
In the first case, the borders are not included in the solutions, and in the second case, the borders are included.
Where the solutions will be points like (x, y), where these points must be solutions for both inequalities.
Then the only option that is correct for a general system of inequalities is:
A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Answer:
A solution of a system of linear inequalities is an ordered pair that satisfies at least one of the inequalities in the system.A solution of a system of linear inequalities is an ordered pair that satisfies the intersection of the border of each inequality.A solution of a system of linear inequalities is an ordered pair that satisfies neither inequality in the system.A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.

A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?
0.10
0.21
0.35
0.40
Answer:
Okay so!
Step-by-step explanation:
for a cut that's .87 and for a color that is .24 so you multiply them together to get the probability for the color which is
.35 or C on edge
The probability that a randomly selected customer gets their hair cut and colored is .
What is probability?Probability is the chance of happening an incident or event. A probability is calculated by the ratio of the possible outcomes to total number of outcomes.
Given, the probability of he customer get a hair cut is = P(A) = 87% = 0.87.
The probability of he customer get their hair colored is = P(B) = 40% = 0.4.
Therefore, the probability of a randomly selected customer get hair cut and hair color is = P(A) × P(B) = 0.87 × 0.4 = 0.35
Therefore, 35% of the total customer get hair cut and color.

Step 1: Define inequality
-36x - 24 ≤ -6(5x + 12)
Step 2: Solve for x
Distribute -6: -36x - 24 ≤ -30x - 72Add 36 on both sides: -24 ≤ 6x - 72Add 72 on both sides: 48 ≤ 6xDivide both sides by 6: 8 ≤ xRewrite: x ≥ 8Here we see that any number x greater than or equal to 8 would work as a solution.
Students plan to pay back half the debt now though fundraising, and the rest after the harvest. Write an equation to represent the debt they will repay through fundraising. Use a negative integer to show debt. Use "D" to represent the debt that will be repaid by through fundraising.
Answer:
D = [tex]\frac{-d}{-2}[/tex]
Step-by-step explanation:
The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2 in order for the total to be positive.
D = [tex]\frac{-d}{-2}[/tex]
Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser

Answer:
D. 181.7 miles
Step-by-step explanation:
If the odometer can read to the nearest 0.1 miles, then you don't want to use A because its not as precise. You don't want to use B because its rounded up to the nearest hundreds. You don't want to use C because we don't know whats in the hundredths place, if the odometer only reads to the nearest 0.1 miles then it could be 181.3, or 181.9, we don't know that. Your answer is D.
This morning, Mai's car had 15.25 gallons of fuel. Now, 1.9 gallons are left. How much fuel did Mai use?
Answer:
13.35
Step-by-step explanation:
Just subtract. 15.25-1.9 gives you the difference.
Mai used 13.35 gallons of fuel.
Unitary method is a process by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
To calculate the fuel Mai used, we can subtract the remaining fuel from the initial amount of fuel.
This can be done as follows:
Initial amount of fuel = 15.25 gallons
Remaining amount of fuel = 1.9 gallons
Fuel used = Initial amount of fuel - Remaining amount of fuel
Therefore, Fuel used = 15.25 - 1.9
Fuel used = 13.35
Therefore, We can conclude that Mai used 13.35 gallons of fuel.

If f(x) = (2x + 1)2 – 3 and g(x) = 2(2x2 + 3), which statement is true?
A. f(-5) = g(4)
B. f(3) = g(0)
C. f(1) = g(1)
D. f(-3) = g(-2)
Answer:
d
Step-by-step explanation:
becasuse when you multiply all that stuff since x is the is y fancy way o f saying
From the calculations, we can see that the true statement is f(-3) = g(-2): Option D is correct.
Given the following functions
f(x) = (2x + 1)²– 3 and g(x) = 2(2x² + 3),
According to the last option.
f(-3) = (2(-3) + 1)²– 3
f(-3) = (-6+1)² - 3
f(-3) = (-5)² - 3
f(-3) = 25 - 3
f(-3) = 22
For g(-2)
g(-2) = 2(2x² + 3),
g(-2) = 2(2(-2)² +3)
g(-2) = 2(8+3)
g(-2) = 2(11)
g(-2) = 22
Hence from the calculations, we can see that the true statement is f(-3) = g(-2)
