11 9/10 First you have to add 10 3/5 and 12 1/2. You get 22 11/10. That is an improper fraction. There are one 10 in 11. So you add 1 1/10 to 22. You get 23 1/10. Now you have to subtract 23 1/10 and 35. You get 11 9/10

Solve the system using any method.<br> y = 3x + 2<br> y = 7x - 10
Marysya12 [62]

Answer:

x=3

y=11

Step-by-step explanation:

y = 3x + 2   equation 1

y = 7x - 10   equation 2

using equation 1 in equation 2 we have:

3x + 2   = 7x - 10

2=7x - 3x -10

2 = 4x -10

2+10 = 4x

12= 4x

12/4 = x

we have:

x= 3

using equation 1:

y = 3x + 2

y= 3(3)+2

y=9+2

y=11

Plz help I am giving away 20 points!!!!!!!!
vova2212 [387]

Okay, so on number one I have no idea. I keep getting 20 because 14 - (-3)2 = 14- (-6) which is really 14 + 6=20.

Number 2 is r+15=61

Number 3 I didn't get any of those answers because you have to solve what is in the parenthesis first so3*5= 15+1=16 then you multiply that by two giving you 16*2=32 and 42-32=10

Able, Ben and Cal each played a game able's score was six times ben's score, Cale score was a hird time of Able's score write do
Svetradugi [14.3K]

Answer:

Abel to Ben: 6

Abel to Carl: 3

Ben to Carl: 0.5

Step-by-step explanation:

First we formulate the problem in equations:

Abel = 6 * Ben

Cale = Abel / 3

If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.

If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)

So, the ratio between all scores are the following:

Abel to Ben: 6

Abel to Carl: 3

Ben to Carl: 0.5

The drama club sold bags of candy and cookies to raise money for the spring show. Bags of candy cost $5.50 and bags of cookies c
vaieri [72.5K]

Let's assume

the number of bags of candy =x

the number of bags of cookies =y

There were 5 more bags of cookies sold than candy

so, we get

y=x+5

Bags of candy cost $5.50

so, total cost of candy is

=5.50x

bags of cookies cost $3.50

so, total cost of cookies is

=3.50y

so,

total cost = (total cost of candy)+(total cost of cookies)

we get

total cost =5.50x+3.50y

so, we can plug

5.50x+3.50y=53.50

now, we can plug y

5.50x+3.50(x+5)=53.50

5.5x\cdot \:10+3.5\left(x+5\right)\cdot \:10=53.5\cdot \:10

55x+35\left(x+5\right)=535

55x+35x+175=535

90x+175=535

90x+175-175=535-175

90x=360

x=4

now, we can find y

y=x+5

y=4+5

y=9

so,

the number of bags of candy =4

the number of bags of cookies =9............Answer
