What is the answer 3x-5=2x-1
Answer:
x=4
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
3x - 5 = 2x -1
Add 5 to both sides
3x - 5 + 5 = 2x - 1 + 5
3x = 2x + 4
Subtract 2x form both Sides
3x - 2x = 2x - 2x + 4
x = 4
A type of electric car can travel 3 miles on 1 kilowatt hour of electricity. How many kilowatt hours of electricity would it take to drive electric car to 's house and back? Lives miles from .
Answer:
Question is incomplete so I'll use a reference.
Assume the person whose house the car went to is 21 miles away.
The car would have had to go back and forth so the total distance spent would be:
= 21 + 21
= 42 miles
The car uses 1 kilowatt hour to go 3 miles. Now it has to go 42 miles.
The number of kilowatt hours it will need are:
= Distance / distance per kilowatt hour
= 42 / 3
= 14 kilowatt hours

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.
Write an equation to represent Steve's situation.
Answer:
[tex]250 - 20x=y[/tex]
Step-by-step explanation:
As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.
Steve's saving would be equal to his initial value, minus his expense, in essence;
[tex]250 - 20x=y[/tex]
The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
Answer:
y=250-(20x)

What are the steps to solving the equation: -3w+9= -12
Answer:
Simplify each side of the equation by removing parentheses and combining like terms.
Use addition or subtraction to isolate the variable term on one side of the equation.
Use multiplication or division to solve for the variable.
Step-by-step explanation:
Answer:
Solution
= −7
Step-by-step explanation:
3 + 9 = − 12
3 + 9 − 9 = − 12 − 9
Subtract the numbers
Subtract the numbers
3 = − 21
Divide both sides of the equation by the same term
3 = − 21
3/3 = −21/3
Solution
= −7

a. Solve 2x + 6 < 10.
b. Solve - 2x + 22 < 18.
Answer:
2
Step-by-step explanation:
1 Subtract 66 from both sides.
2x=10-6
2x=10−6
2 Simplify 10-610−6 to 44.
2x=4
2x=4
3 Divide both sides by 22.
x=\frac{4}{2}
x=

4
4 Simplify \frac{4}{2}

to 22.
x=2
x=2
Done
2x+22=18
We move all terms to the left:
2x+22-(18)=0
We add all the numbers together, and all the variables
2x+4=0
We move all terms containing x to the left, all other terms to the right
2x=-4
x=-4/2
x=-2

Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
Answer:
16 meters
Step-by-step explanation:
Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
The formula to solve for the above question is:
Diagonal² = Width² + Length²
34² = 30² + L²
Collect like terms
L² = 34² - 30²
L = √34² - 30²
L = √(256)
L = 16 meters
Therefore, the length of the ceiling is 16 meters

A university president believes that over the past few years, the mean age of students attending his university has decreased. To test this hypothesis, a study is conducted in which the age of 150 students who have been randomly sampled from the student body is measured. The mean age is 21.5 years. A complete census taken at the university a few years prior to the study showed a mean age of 23.5 years, with a standard deviation of 8.5. Test using a 1% level of significance.

What is the limit?
The limit is a value that a function (or sequence) approaches as the input (or index) approaches some value.
A parabola opens up approaches StartFraction pi Over 2 EndFraction, has vertex (0, 1), and approaches StartFraction pi over 2 EndFraction. The parabola flips over the x-axis at every measure of pi.

How many packages of diapers can you buy with $40 if one package costs $8?
Write and solve an equation for the above situation. Use "p" as the variable
Answer:
Step-by-step explanation:
Im not sure about the first two about fraction bars, a fraction bar looks like this 1/10 or 4/9, maybe the question is asking you to make a fraction of each side so that they both equal the same thing using common denominators.
In that case #2 would be 21/3= 21/7
still not sure about #1
X+32=40
subtract 32 on each side
x+32-32=40-32
x=8
At a restaurant, Mike and his three friends decided to divide the bill evenly. If the total bill was $51.24, how much did each person pay?
Write and solve an equation for the above situation. Use "b" as the variable
4b=51.24
divide each side by 4
4b/4= 51.24/4
b=12.81
Each friend spent $12.81 on the bill.
How many packages of diapers can you buy with $40 if one package costs $8?
Write and solve an equation for the above situation. Use "p" as the variable
8p=40
divide each side by 8
8p/8=40/8
p=5
You can buy 5 packages of diapers with $40
