An equation is formed when two equal expressions. Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let x be the number of volleyballs and y be the number of basketballs. Therefore, the total number of balls can be written as,
x + y = 45
x = 45 - y
Each volleyball costs $8 and each basketball costs $11. Also, Ms. Kilicoglu has only $435, therefore,
8x + 11y = 435
8(45 - y) + 11y = 435
360 - 8y + 11y = 435
3y = 75
y = 25
Substitute the value of y in the first equation,
x + y = 45
x + 25 = 45
x = 20
Hence, Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.

Answer:
a. Feelings about weight is the response (dependent) variable. Sex is the explanatory (independent) variable. The feelings about weight depend on the sex
b. Summary of observed counts
Women Men Total
Overweight 38 18 56
Right weight 99 35 134
Underweight 6 25 31
Number 143 78 221
c. Percentage of the 143 women responding in each category:
1. Overweight = 38/143 = 26.6%
2. Right weight = 99/143 = 69.2%
3. Underweight = 6/143 = 4.2%
d. Percentage of the 78 men responding in each category:
1. Overweight = 18/78 = 23.1%
2. Right weight = 35/78 = 44.9%
3. Underweight = 25/78 = 32%
e. Summary of feelings about weight:
Women Men
Overweight 26.6% 23.1%
Right weight 69.2% 44.9%
Underweight 4.2% 32%
Step-by-step explanation:
a) Data:
Sample size = 221
Women Men Total
Overweight 38 18 56
Right weight 99 35 134
Underweight 6 25 31
Number 143 78 221
b) To obtain the percentage of feelings about weight for each category, the number of those who feel overweight, right weight, or underweight is divided by the total number of women or men. The value obtained, which is in decimal form, is then converted to percentage by multiplying with 100.

Answer:
x = 7
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so ...
11x +6 = -6x +125
17x = 119 . . . . . . . . . add 6x-6 to both sides
x = 7 . . . . . . . . divide by 17
Two is less than three which is also less than 5.
When put into a number line from 0 to 10, it shows that 2 is closest to 0 while 5 is closest to 10 and three, will be in between 2 and 5. This shows that as you go from 2 to 3, the number increased and, it continues to increase when you go from 3 to 5. This shows that 2 is less than 3 and 3 is less than 5.
Answer:
5.95%
Step-by-step explanation:
Bond 1:
I = 250(.05)5
I = $62.50
Bond 2:
62.5 = 350(3)r
62.5 = 1050r
r = 62.5/1050
r = 5.95%
