My brainy brother and sister added their ages together and got 15. When they multiplied their ages together, they got 54. How old is the older one between the two of them?
Given:
Sum of ages of brother and sister = 15
Product of their ages = 54
To find:
How old is the older one between the two of them?
Solution:
Let x be the age of brother and y be the age of sister.
Sum of ages of brother and sister = 15
[tex]x+y=15[/tex]
[tex]x=15-y[/tex] ...(i)
Product of their ages = 54
[tex]xy=54[/tex]
[tex](15-y)y=54[/tex] [Using (i)]
[tex]15y-y^2=54[/tex]
[tex]0=54-15y+y^2[/tex]
Splitting the middle term, we get
[tex]54-15y+y^2=0[/tex]
[tex]54-9y-6y+y^2=0[/tex]
[tex]9(6-y)-y(6-y)=0[/tex]
[tex](6-y)(9-y)=0[/tex]
Using zero product property, we get
[tex](6-y)=0\text{ and }(9-y)=0[/tex]
[tex]y=6\text{ and }y=9[/tex]
If [tex]y=6[/tex], then using (i), we get
[tex]x=15-6[/tex]
[tex]x=9[/tex]
If [tex]y=9[/tex], then using (i), we get
[tex]x=15-9[/tex]
[tex]x=6[/tex]
Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.

Toby and Ahmed are eating pizza. Toby eats 1/2 of the pizza and Ahmed eats 1/4 of the pizza. How much of the total pizza have they eaten? 1 point
Answer:they have eaten 3/4 of the total pizza
Step-by-step explanation:
Let the whole pizza =1whole
Amount eaten by Toby =1/2
Amount eaten by Ahmed =1/4
Total Amount eaten by both of them =1/2 +1/4 = 2+1/ 4=3/4
Therefore, they have eaten 3/4 of the total pizza

Triangle ABC has vertices A(-2,0), B(2,5), C(3, 1). The reflection of the image of triangle ABC is triangle A'B'C' with vertices A(-2,0), B12, -5), C73.
-1). What is a rule that describes the reflection?
Answer: Reflection about x-axis
Step-by-step explanation:
Given
Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]
After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]
It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.
For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).
So, here reflection is being done about the x-axis.

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
y = 75.2
By = 52
C y = 2
Dy = 152
Answer:
one board game cost 15 dollars
75/5=15
15y
y = number of board games and 15= the price of each board game
so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.

Find the median and mean of the data set below:
9,10,38,0,26,35,8
Answer:
Median = 10
Mean = 18
Step-by-step explanation:
1) Median equals the middle number of a set.
To find median, place the numbers from least to greatest. So that’ll turn to be:
0, 8, 9, 10, 26, 35, 38
The middle number is 10.
2) Mean is the average of all the numbers.
To find mean, add all the numbers together. So 0+8+9+10+26+35+38 = 126
Then, divide the sum by the amount of numbers you added. We added a total of 7 numbers to get 126. 126/7 = 18. The average is 18.
Answer:
The median is 10 and the mean is 18 . Hope it help
Step-by-step explanation:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest
A man bought some story books for 5 Ghana Cedis each from a bookshop
15 of the books got missing. He then sold the rest at 8 Ghana cedis each and made a profit of 90 Ghana cedis. How many books did he buy?
Answer:
70
Step-by-step explanation:
Let the no of books bought be x
The cost price of 1 book is 5x
No of the missing book is 15
The remaining book is x-15
The selling price of 1 book is 87
Selling price of (x-15) book is 87
Hence the number of books can be calculated as follows
8(x-15)-5x= 90
8x-120-5x= 90
8x-5x= 90+120
3x= 210
x= 210/3
= 70
Hence the number of books bought is 70

Number of people who voted for dogs:
12
Number of people who voted for fish:
4
We find the difference between the 2:
12 - 4 = 8
Answer:
8 students voted for dogs than fish.
Step-by-step explanation:
so if we look at the graph 12 students voted for dogs and 4 students voted for fish. so now we have to subtract both of these numbers to find how many more students voted for dogs than fish.
12 - 4 = 8
