Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?
Answers
Answer:
$20.30
Step-by-step explanation:
Original price = 100% of the price
100% = $29
1% = 29 ÷ 100 = 0.29
Sale percentage = 30%
30% = 0.29 x 30 = 8.70
Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.
29 - 8.70 = 20.3

4) A dozen cookies cost $18.75. Twenty cookies cost $25.50. Which has the lower unit price?
ROUND YOUR ANSWER TO THE NEAREST HUNDREDTHS. *
Answers
Answer:
Twenty cookies deal
Step-by-step explanation:
A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.

have a great day!!!
If two ratios are similar we called the ratios to be in proportion.
The length of side x is 6 cm.
What is proportion?If two ratios are similar we called the ratios to be in proportion
We have,
Two shapes:
Consider the bigger shape width = 15 cm and length = 10 cm.
Consider the smaller shape width = 9 cm and length = x cm.
Let the ratio of bigger shape:
= Width / length
= 15/10
Let the ratio of smaller shape:
= Width / length
= 9/x
If the two figures are mathematically similar we can say that the two figures are in proportion.
We can write it as:
15/10 = 9/x
3/2 = 9/x
x = 6
Thus the length of side x is 6 cm.

82% of what number is 492?
Answers
answer
600
Step-by-step explanation:
Step 1: If 82% of a number is 492, then what is 100% of that number? Setup the equation.
492/82%=Y/100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
82Y = 492 x 100
82Y = 49200
Y=49200100=600

Step-by-step explanation:
When solving 8x-8≤-72, first add 8 to both sides of the inequality.
This leaves you with 8x≤-64.
Divide both sides by 8: 8x/8 and -64/8
This leaves you with x≤-8 as your solution.

need help with 2 look at the Photo
Answers
Answer:
x = 15
Step-by-step explanation:
x + 2y = 37
x - y = 4
x + 2y = 37
2x - 2y = 8
3x = 45
x = 15
Steps:
1. Isolate y in the equation x - y = 4
x - y = 4
-y = 4 - x
y = 4 - x / -1
2. Substitute value of x (15) into the new equation y = 4 - x / -1
y = 4 - 15 / -1
y = -11 / -1
y = 11
3. Plug in your y value (11) and x value (15) into the equation x + 2y = 37
15 + 2(11) = 37
15 + 22 = 37
37 = 37 ✅
4. Plug in your y value (11) and x value (15) into the equation x - y = 4
15 - 11 = 4
4 = 4 ✅
both equations are true with the value of x being 15 therefore your answer is
(4) x = 15
