Can someone please help me with this? Thank you!

Answers

Answer:

2 1/2

Step-by-step explanation:

5/8 / 1/4
5/8 x 4/1
cross cancel 4 and 8 to get 5/2 x 1/1
answer 5/2 or 2 1/2

5/8 divided by 1/4 equals 5/8 times 4/1

that equals 5/2 which becomes 2 1/2

Answers

so y=mx+b
the 'm' part means the slope which is found by 'rise/run'
a. y=2x+3 or y=2x+3
b. y=-1x+6
c. i'm not sure what this part means
d. this means 'what values will work for x and y in both equations at once so
y=-x+6 and y=2x+3
y=-x+6
add x to both sides
x+y=6
subtitute 'y=2x+3' for y in x+y=6
x+(2x+3)=6
collect like terms
3x+3=6
subtract 3 from both sides
3x=3
divide both sides by 3
x=1
sibtitue into x+y=6
1+y=6
subtract 1 from both sides
y=5

Describe two methods for finding the sale price of an item that is discounted 30%. which method do you prefer? Explain.

Answers

Answer:

1. Find the value of the discount amount, and subtract from the original.

2. Find the value of the item after discount by using 100%-30%.

I prefer the second, as it is faster.

Step-by-step explanation:

1. Find the value of the discount amount, and subtract from the original.

Say y is the amount you pay after the discount, and x is the original price, the calculation will look like this:

The value of the discount is 30% of x, which is equal to 0.3x.

subtract that from the original value to find y:

y = x - 0.3x

2. Find the value of the item after discount by using 100%-30%.

The amount left over after subtraction thirty % is 70%

Thus,

y = 0.7 x

one can take the price of the item before the discount is applied and subtract that from the percentage off and get the cost of the item.

I find this is the most effective way.

another method could be if one turned the percentage into a decimal it could be subtracted from the cost of the item.

Mick paid $2.94 in sales tax on a item that cost $42.00 before tax. At tthat rate, how much would he oay in slaes tax for an item thyat costs $58.00 before tax?

Answers

Sales Tax Rate = 2.94/42 x 100 = 7%

Item = $58

Sales Tax = 7% of $58 = 0.07 x 58 = $4.06
