Answer:
How many apples did Mr. Rozario buy?
16 apples
How many oranges did Mr. Rozario buy? 40 oranges
Step-by-step explanation:
From the question, we know that:
The ratio of the number of apples to the number of oranges are 2:5.
We represent the total number of fruits as x
Let
The number of apples he bought be represented as 2x
The number of oranges he bought be represented by
= 5x
He gave 3/4 of the apples to his sister and 34 oranges to his brother.
This means now, the number of apples he has left =1 - 3/4(2x) = 1/4(2x)
The number of oranges he has left = 5 - 34
The ratio of the number of oranges to the number of apples that he has now is 2:3.
1/4(2x) : 5x - 34 = 2:3
x/2:5x - 34 = 2:3
= x/2/5x-34 = 2/3
Cross Multiply
(x/2)3 = 5x - 34(2)
3x/2 = 10x - 68
Cross Multiply again
3x = 2(10x - 68)
3x = 20x - 136
20x - 3x = 126
17x = 126.
x = 126/17
x = 8
Hence:
The number of apples he bought be represented as 2x
So: 2 × 8 = 16 apples
The number of oranges he bought be represented by
= 5x
so: 5 × 8 = 40 oranges
Therefore, the number of Apples Mr Rosario bought is 16 apples
The number of oranges Mr Rosario bought is 40 oranges

You are planning a skating party at a rink that charges a basic fee of
$10.00 and $6.00 per person for catered parties. You don't want to spend
more than $52.00. Write and solve an inequality to find the number of
friends you can invite.
a. 6x + 10 < 52; x< 7
6. 6x + 10 > 52; <> 7
C. 6% + 10 > 52; 2 >7
d. 6x + 10 < 52; x < 7
Answer:
y = 6.50x + 6 or 71 = 6.50x + 6
10 people are the max you can invite
Step-by-step explanation:
We have the simple equation
y = 6.50x + 6
6.50x because it it per person
6 because it is a flat one time charge
We want the max to be 71 so that will be our y
71 = 6.50x + 6
We are now going to solve for x
65 = 6.5x
x = 10

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?
If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(
Answer:
80%
Step-by-step explanation:
100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.
Answer:
80% are left.
Step-by-step explanation:
So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.
Solve the system of equations:
y= -x + 9

Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer
Answer:
no
Step-by-step explanation:
y = -2x + 16
-2 = -2(10) + 16
-2 = -20 + 16
-2 = -4
which is wrong
Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.
y = -2x + 16 > -2 = -2(10) + 16
Now, solve.
-2 = -2(10) + 16 > -2 = -20 + 16 - Start by multiplying out parenthesis.
-2 = -20 + 16 > -2 = -4 - Add.
-2 = -4
The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.
