Question

PLzz just one question

Answer 1

Solve the system using substitution.
x = 2y + 6 y = -3 and x =0
x + y = 12 x = 0and y = 12
10) Solve the system using elimination.
3x – 9y = 18 x = 9 and y = 1
x + 2y = 1
x = 1 and y = 0

Answer 2

Let me see what I can do??

Answer 3

@Pianolover03 can you help with this question

Answer 4

Are these two questions or 1?

Answer 5

Answer 9

my brain is messed up today I already did that one here is the question

A test has twenty questions worth 100 points. The test consists of True/False questions worth 3 points each and multiple choice questions worth 11 points each. How many multiple choice questions are on the test? There are 5 and 15 true/false

Answer 10

... now? or in forty minutes? lol :3

Answer 11

Not that it matters... again, it looks like you've already done it :P

Answer 12

Let T be the number of true/false questions and let M be the number of multiple choice questions. Since there are 20 questions, we have

T + M = 20

Our second equation is based on the points,

3T + 11M = 100

Solve the first equation for T,

T = 20 - M

Plug into the second equation,

3(20 - M) + 11M = 100

60 - 3M + 11M = 100

8M = 40

M = 5

T = 20 - M = 15

So we have 15 true/false questions and 5 multiple choice questions

Answer 13

Yep, lol =)

Answer 14

yeah im seing if it is right

Answer 15
