Answer: 24/25
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:
Step-by-step explanation:
The sum of angles in any triangle is 180°.
(x +45) +(2x +95) +(3x +48) = 180
6x +188 = 180 . . . . . . . . collect terms
6x = -8 . . . . . . . . . . . subtract 188
x = -4/3 . . . . . . . . divide by 6
Then the angles are ...
x +45 = -4/3 +45 = 43 2/3°
2x +95 = 2(-4/3) +95 = 92 1/3° . . . . the obtuse angle
3x +48 = 3(-4/3) +48 = 44°
