Answer:
Option B: 3x + 3y - 3
Step-by-step explanation:
In an isosceles triangle, the two congruent sides are equal.
We are told the base is; x - y - 2 units
Now let each of the congruent sides be represented as A.
Thus the perimeter equation will be;
P = 2A + x - y - 2
Now, we are told that the perimeter is; 7x + 5y - 8 units
Thus;
7x + 5y - 8 = 2A + x - y - 2
Rearranging gives;
7x - x + 5y + y - 8 + 2 = 2A
2A = 6x + 6y - 6
Divide through by 2 to give;
A = 3x + 3y - 3 units
Your answer is 3/2 i know for a fact
He bought 3 scoops, each costing $1.19
The cost of the three scoops= 3*1.19= $3.57
Total cost of scoops and toppings is $4.55
Cost of toppings only= 4.55-3.57= $0.98
Each topping costs $0.49
Therefore number of toppings bought= 0.98/0.49= 2
Answer: 2 toppings
Hi there! The answer is C.
Explanation:
We have the following equation:

To solve this type of equation (with an x in the denominator of a fraction) we must cross-multiply the numerator and the denominator.

Multiply

Divide both sides by 15.
