Answer 1

Answer:

1.) x = 3/2 y - 1 y =2/3 x + 2/3

Step-by-step explanation:

Answer 2

Answer:

(-1,16)

Step-by-step explanation:

You can use the elimination method...

Make 2x -3y = -2 negative by multiplying by -1.

Then add both equations together, since you made the first one negative, you were able to cancel out both 2x. You're left with 4y = 16.

Next divide by 4 on both sides ---> 4y/4 and 16/4 to get an answer to the Y- coordinate of 16. So since you have Y=16, you can just plug it in to one of the original equations and solve for X.

So then you end up with x as -1 and y as 16.

Stephen bought enough powdered juice mix to make 834gallons of juice. If his kids go through 125gallons of juice per week, how many week’s worth of juice did he buy?

Answers

I think the answer would be around 6.672

Answer:

Read explanation so you can learn

Step-by-step explanation:

Divide the total amount of juice with the amount of juice the kids drink per week, 834/125 and you will get 6.672, So it will take about 6.6 weeks for the kids to drink all of the juice.

If 35 people going to the movie bought popcorn and that was 20% of all the people at the movie how many people were at the movie

Answers

Answer:

Im pretty sure it would be 700 but im most likely wrong.

The correct answer is 175

If 35 people is 20% of all people, we can assume that 35 is 1/5 of all the people at the movie since 20% is 1/5 of 100%

All we have to do is multiple 35 by five.

I can prove my answer by dividing 175 by 5 which would give me 20% of 175

What must be true of the side lengths in order to build a triangle with only two angles the same size?

Answers

Answer:

A triangle with two angles of the same size is an isosceles triangle. So two of its sides are going to have the same measure and the third different. The length of the sides will depend on the height of the measure of the given angles.

Step-by-step explanation:

Isosceles triangles can be classified into an isosceles right triangle, isosceles obtuse, isosceles acute depending on the measurements of its internal angles.

A person wants to purchase a pair of shoes and some pairs of socks. He has less than $121 to
spend. If a pair of shoes costs $30 and each pair of socks costs $8, what is the maximum
number of pairs of socks he can purchase?

Answers

the answer is 11

first you need to subtract 30 from 121 since you want one pair of shoes

then to know how many socks you can have divide 91 (the result) and 8 (the price of the socks)

and you can only buy 11

(the more detailed answer is 11.375)

A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population after x years.

Answers

Answer:

f(x) = 300,000(1.05)^x

Step-by-step explanation:

Use the exponential growth equation:

f(x) = a(1 + r)^x

Plug in 300,000 as a, since it is the original population:

f(x) = 300,000(1 + r)^x

The city's population is growing at 5% each year, so plug in 0.05 as r:

f(x) = 300,000(1 + 0.05)^x

f(x) = 300,000(1.05)^x

So, the function for the population growth is f(x) = 300,000(1.05)^x

Find the median of the following numbers:
95, 113, 95, 105, 86, 122

Answers

Answer:

100

Step-by-step explanation:

First, order the numbers from least to greatest.

86, 95, 95, 105, 113, 122

Second, look for the middles numbers, if you have an even amount of numbers you will have to find the mean of the two middle numbers.

86, 95, 95, 105, 113, 122

Thirdly, add 95 and 105 together and then divide by two because two is the total amount of numbers you have.

(95 + 105) / 2 = 100.

So the median is 100

Ivan and Tanya share £150 in the ratio 4:1
Work out how much more Ivan gets compared to Tanya.

Answers

Given: Ivan and Tanya share £150 with a 4:1 ratio.

Let x represent the variable amount of money.

Ivan: 4x
Tanya: x

4x + x = £150
5x = 150
x = 30

Ivan = 4(30) = £120
Tanya = £30

£120 - £30 = £90

Therefore Ivan gets £90 more than Tanya, which is four times more than Tanya.
