Answer:

Tim is correct

Answer:

Tim is correct

Step-by-step explanation:

Since we are given an expression, we will use the clue (y = 8) to solve the expression and evaluate who is correct. Lets get started!

8y + 2y

=> 8(8) + 2(8)                                                                                             [y = 8]

=> 64 + 16

=> 80

After solving the expression with 6 as our y value, we got 80 as our answer. Now lets see who is correct.

Randi says 74, but 74 is not equaled to 80. So Randi is wrong.

Tim says 80, and 80 equals 80. So Tim is right.

Marco says 28, but 28 is not equaled to 80. So Marco is wrong.

Sandi says 32, but 32 is not equaled to 80. So Sandi is wrong.

After checking everyone's answer, we found that Tim was right. Therefore, Tim is the answer.

Please give me brainliest :D

Omg help me please like I just can't right now <br><br> 2x-6y= -12 <br> x+2y=14
steposvetlana [31]

here,

2x-6y= -12

2(x-3y)= -12

x-3y = -6...........eq1

x+2y=14............eq2

we can subtract the above two given equations

we get,

x - 3y =  - 6 \\ x + 2y = 14

___________

- 5y =  - 20

so,

y=4

now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2

we get,

x + 2y = 14 \\ x + 2 \times 4 = 14 \\ x + 8 = 14 \\ x = 14 - 8 \\ x = 6

<h3>so,</h3><h3> x=6,y=4</h3>

Sarafina and Katie have between $105 and $420 dollars to spend on jewelry for Christmas presents for their friends. If they buy
algol13

Answer:

66

Step-by-step explanation:

105+420=525   (Total Money)

7x3.25=22.75   (Cost of all bracelets)

8x11.74=93.92   (Cost of all necklaces)

93.92+22.75=116.67   (Cost of all Christmas presents)

525-116.67=408.33   (Total money - Cost of all Christmas presents)

408.33/6.15=66.39...   (Amount of necklaces)

since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!
