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
Answer:
96 ounces of lime
Step-by-step explanation:
12 ounces of lime to 10 ounces of water
80 ounces of water means the amount of water increased 8 times
so you have to increase the amount of lime 8 times as well
12 ×8 =96
When in doubt, draw a picture. The vertex of the equation is at (3,0) and the y-intercept is at (0,4.5). The answer is D
<span>Simplifying
4n + -19 = 13
Reorder the terms:
-19 + 4n = 13
Solving
-19 + 4n = 13
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '19' to each side of the equation.
-19 + 19 + 4n = 13 + 19
Combine like terms: -19 + 19 = 0
0 + 4n = 13 + 19
4n = 13 + 19
Combine like terms: 13 + 19 = 32
4n = 32
Divide each side by '4'.
n = 8
Simplifying
n = 8</span>
