1.$11.78 2.3x-2 3. Number line graph with closed circle on 120 and shading to the right. 4.yes ,because the total will be$3.27

5.x 0 2 4

and y 0 24 48

6.x= 14

7.x=4

8.4.2

9.y= 4x

10.y=12x

Step-by-step explanation:

1.Lacey has total money for spend=$36 cost of 1 pair of sunglasse=$14.89

cost of a hat=$9.33 spend money =$14.89+$9.33=$24.22

Lacey has remaining money for buying scarf=$36-$24.22=$11.78 2. If kim's age = x years given that sam's age is 2 years less than 3 times kim's age therefore the expression best shows sam's age is $3x-2$ 3. A group of students must collect at least$150 to organise a science fair.

they have already collected money=$30 now remaining money =$120

hence ,the graph is number line graph with closed circle on 120 closed circle and shading to the right  which represents all remaining amounts of money.

4.Cost of a sticker=$0.35 Cost of an eraser=$0.99

Cost of pencil=$0.59 cost of 2 stickers =2*0.35=$0.70

cost of 2 erasers=2*0.99=$1.98 total cost including 2 stickers ,2 erasers and one pencil=$3.27

hence minni can buy 2 stickers and 2 erasesrs.

5. y= 12x

put x=0 in given expression y=12x then we get y=0

now put x=2 in this expression then y=24

and now put x=3 in this expression  then we get y= 48.

6.x+7.5=21.5

x =21.5- 7.5=14

8.$1/24*x=1/6$

x=24*1/6=4.

8.x+2=6.2

then x =6.2-4=4.2

9.A store sold copies of a magazine =60

cost of 60 copies of magazines =\$240

hence , cost of magazines is four times the number of magazines .

therefore , the expression is y= $y=4x$( if number of magazines x)

y=4x; (1,4),(2,8),(3,12)

10.y is 12 times x therefore the relation between x and y is $y=12x$

4.2 Because if you subtract 6.2 and 2 thats what you get.

4.2

Step-by-step explanation:

I took the test and got it right

5. Playboycxm says:

1)11.78
2)3x-2
4)yes becouse the total will be 3.27
6)x=14
7)x=4
the last one )y=12x

6. sallabar2496 says:

4.2) 6.2-4.2= 2
Any of the other answers do not make an applicable equation.

Hello,

Hope this helps (:

8. smeeden says:

4.2 because 4.2
+2.0

6.2

9. airrish says:

The number 4.2 from the set will make the equation x+2=6.2 true.
