2 answers:
Answer:
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
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.
x=24*1/6=4.
8.x+2=6.2
then x =6.2-4=4.2
hence answer is 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= ( 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
