Solve the system of equations using elimination.
3x-2y=5
x+2y=3
Answer:
x = 2
y = 1/2
Step-by-step explanation:
3x - 2y = 5
x + 2y = 3
We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.
4x = 8
x = 2
Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.
2 + 2y = 3
2y = 1
y = 1/2
Now we figured out y. I hope I helped!
Games Galore Super Store buys the latest video game at a wholesale price of $30.00. The markup rate at Game's Galore Super Store is 40%. You use your allowance to purchase the game at the store. How much will you pay, not including tax and explain your reasoning. *
Answer:
$42Step-by-step explanation:
By definition, Markup is the difference between a product's selling price and cost as a percentage of the cost.
For example, if a product sells for $125 and costs $100, the additional price increase is ($125 – $100) / $100) x 100 = 25%.
Given data
firstly let us solve for 40% of $30
=40/100*30
=0.4*30
=$12
therefore the sale price will be the markup rate plus the initial price
Hence the you will have to pay 12+30=$42

There were 43 cars in the race. They all finished the 265 miles of the race and they each used about 1 gallon of gas to go 5 miles. About how many gallons og gas did the cars use altogether to finish the race?
Answer:
2,279 gallons of gas.
Step-by-step explanation:
Given;
total number of cars in the race, t = 43 cars
total distance traveled by each car, d = 265 miles
5 miles ---------------- 1 gallon of gas
265 miles ------------ x gallon of gas
x = 265 / 5
x = 53 gallons
Total gallons of gas used by the 43 cars in the race is given as;
Total gallons of gas = 53 gallons x 43 cars
Total gallons of gas = 2,279 gallons of gas.
Therefore, the toal gallons of gas the cars used altogether to finish the race is 2,279 gallons.
Solve the system of linear equations by substitution.
1/2x +y=-4
y = 2x + 16
Answer:
y = 0
x = -8
Step-by-step explanation:
1/2x + y = - 4
y = 2x + 16
1/2x + (2x + 16) = - 4
1/2x + 2x = - 4 - 16
5/2x = -20
2/5 x 5/2x = -20 x 2/5
x = -40/5
x = -8
y = 2x + 16
y = 2(-8) + 16
y = -16 + 16
y = 0
Check:
1/2x + y = - 4
y = 2x + 16
1/2(-8) + (0) = -4
-4 + 0 = -4
-4 = -4
y = 2x + 16
(0) = 2(-8) + 16
0 = -16 + 16
0 = 0
What is the 5th term of an arithmetic sequence of 20 terms with first and last terms of 2 and 59, respectively
Answer:
14
Step-by-step explanation:
aₙ = a₁ + (n-1)*d
59 = 2 + (20-1) * d
59 = 2 + 19d
19d = 59-2 = 57
d = 3

Anthony has 15 coins, all of which are quarters and dimes. In all, they're worth $3.60. How many of each kind of coin does Anthony have?
Answer:
1 Dime
14 Quarters
Step-by-step explanation:
d + q = 15
0.10d + 0.25q = 3.60
d = 15 - q
0.10d + 0.25q = 3.60
0.10(15 - q) + 0.25q = 3.60
1.5 - 0.10q + 0.25q = 3.60
0.15q = 3.60 - 1.5
0.15q = 2.1
0.15q/0.15 = 2.1/0.15
q = 14
d = 15 - q
d = 15 - 14
d = 1

The high school students who attend Washington Preparatory Academy choose their elective classes according to their majors. Students are 37% likely to major in Performing Arts; 43% likely to choose Science and Technology; 82% likely to major in Business and Management; and 63% likely to select Humanities. Many students choose multiple majors. For example, some Science and Technology students also major in Business and Management because they want to be managers in technical companies. Students have equal probabilities of being freshmen, sophomores, juniors, or seniors.
What is the probability of the union of majoring in either Performing Arts or the Humanities?

Given that Students are 37% likely to major in Performing Arts; 43% likely to choose Science and Technology; 82% likely to major in Business and Management; and 63% likely to select Humanities. Therefore, the probability of the union of majoring in either Performing Arts or the Humanities is,
P(Humanities ∪ Arts) = P(Humanities) + P(Arts) - P(Humanities)(Arts)
= 0.63 + 0.37 - (0.63 x 0.37)

A school district has decided that students in grades 7 through 12 should receive 400 minutes of physical education every 10 school days. A gym teacher at one of the schools believes that his students are not meeting this criterion. She randomly selects 50 students and it is found that her students have a mean of 385 minutes and a standard deviation of 55 minutes. Is this evidence to support her claim?
Answer:
Yes
Step-by-step explanation:
Based on the information provided we can say that Yes, this is enough evidence to support her claim. Since the 50 students were randomly selected and the physical education criteria applies to all of the students in that grade range then these 50 students perfectly represent the total population. That being the case, the results gathered to show that with a standard deviation of 55 minutes some students are surpassing the requirement by very little but others are falling very far from that requirement. When it is a requirement for all of the students in that grade range. Therefore, it is enough to support her claim.

Jess earns 10 per hour babysitting. Her friend Sam earns $12.50 per hour. If Jess started with $5, how many hours will both friends need to work before they have the same amount of money.
Answer:
they have to work 2 hours
Step-by-step explanation:
Jess has a $5+ x*$10
Sam has x*$12.5
where x-is number of hour worked
after x=1 hour
Jess has a $5+ 1*$10=$15
Sam has 1*$12.5= $12.5
