solve the systems using substitution
1. y=10x
2x+y = 12
2. x=y+1
x+3y = 9

Answers

Answer 1
??? I don’t get this question
Answer 2
1. Plug in the y= problem to 2x problem. You should get 2x + 10x = 12, 2x + 10x is 12x so the new problem is 12x = 12 divide both sides by 12 and x = 1. Now, plug 1 in for x in y=10x which 10 x 1 = 10 so y is 10. X = 1, Y = 10

2. Same steps different numbers and you plug in x this time instead of y. So, y + 1 + 3y = 9, simplified is 4y + 1 = 9, subtract 1 form both sides. 4y = 8. Divide both sides by 4, y = 2. Plug y in, x = 2 + 1, x = 3. X = 3, Y =2

Ryan is a wrestler trying to make weight. He currently weighs 200 lbs. If he cuts 2 lbs. per week, how many weeks will it take him to weigh less than 175 lbs.?

10 points

Answers

Answer:

12.5 weeks

Step-by-step explanation:

Let's make a equation: 175=200-2x

rearrange it: -2x+200=175

subtract 200 from both sides

-25=-2x

divide both sides by -2

x=25/2

25/2=12.5

Answer:

12.5

Step-by-step explanation:

he wants to weigh 175lbs so he wants to lose 25 pounds,

25/2 = 12.5

Answer:4/5

Step-by-step explanation:

1/5 is closer to zero than 4/5 so we know it can't we that one.

4/8 is equal to 1/2, and 4/5 is closer to 1 than 1/2 is

2/3 multiplied by 5  is 10/15, while 4/5 multiplied by 3 is 12/15

by getting the same denominator we can see that 4/5 is the closest fraction to zero.

The answer is b 4/5 is closer to 1

I’m pretty good with functions, all the numbers in the domain can only have one range ☝ so if for example, 3 had a arrow going to 5 and 7.

Fabiola’s basketball team practices 4.25 hours each week basketball season is 14 weeks long .how much time does Fabiola’s spend in practice during the season? and show how to do the problem

Answers

Answer:

59.5 hours

Step-by-step explanation:

Since Fabiola has basketball practice for 4.25 hours each week and we need to find how much she practices for 14 weeks, you have to multiply.

4.25 x 14 = 59.5

In order to determine the total time, we simply need to multiply 4.25 hours by 14, since the length of time is dependent to the number of weeks.

= (14)(4.25)

=59.5

Final answer:
Fabiola's team spend 59.5 hours in 14 weeks.

Drag and drop one set of parentheses into the expression below so that it's value when simplified is 31. Where would these ( ) go? _2_*4^2_+_square root36_-_13_

Answers

Answer:

2 * (4^2 + squared root of 36) - 13

since the space where the _ are, that's where the parenthyeses would be placed. If you place these around 2, you get 25, is around 4^2, it's also 25, if placed around square root of 36, it will also be 25, but if placed around -13, it's -46. But place then around 4^2 + the square root of 36, then you will get your answer of 31 simplified.

The answer is 2* (4^2 + squared root of 36) - 13
