Answer: the price of each apple is $2.25 and the price of each mango is $1.25
Step-by-step explanation:
Let x represent the price of one apple.
Let y represent the price of one mango.
Cameron went into a grocery store and bought 4 apples and 7 mangos, costing a total of $17.75. This means that
4x + 7y = 17.75 - - - - - - - - - - - - 1
Gavin went into the same grocery store and bought 2 apples and 5 mangos, costing a total of $10.75. This means that
2x + 5y = 10.75 - - - - - - - - - - - - -2
Multiplying equation 1 by 1 and equation 2 by 2, it becomes
4x + 7y = 17.75
4x + 10y = 21.5
Subtracting, it becomes
- 3y = - 3.75
y = - 3.75/ - 3
y = 1.25
Substituting y = 1.25 into equation 2, it becomes
2x + 5 × 1.25 = 10.75
2x + 6.25 = 10.75
2x = 10.75 - 6.25 = 4.5
x = 4.5/2 = 2.25
Answer:
I wish I could help
Step-by-step explanation:
I will try finding the answer
Step-by-step explanation:
For problem 1,
Let the required number be x,
2 x/4 = 11/4
or, (8+x)/4 = 11/4
or, 8+x = 44/4
or, 8+x = 11
or, x = 11-8
so, x = 3
For problem 2,
Let the required number be y,
y/10 = 4/5
or, 5y = 40
or, y = 40/5
so, y = 8
Hello!
You can plug the answers in for x and see if it is right
x^2 + 8x = 33
-11^2 + 8(-11) = 33
121 - 88 = 33
3^2 + 8(3) = 33
9 + 24 = 33
So the answer is the first one
Hope this helps!
