Answer:
$34.29
Step-by-step explanation:
1.08 ( (3 * 8.5) + (5 * 1.25) ) = T
1.08 (25.5 + 6.25) = T
1.08 (31.75) = T
T = 34.29
In A x=64 bc alternate interior angles are congruent and 128/2= 64. In B x=75 bc alternate exterior angles are also congruent and (151-1)/2 = 75. In C x=12 bc consecutive interior angles are supplementary. 7x+24+72=180 180-72-24=84 84/7=12
Answer:
the answer is 4.2 .................
x = - 3
y = -2
Step-by-step explanation:
3x - 8y = 7
x +2y = -7
We standardize the coefficient of one variable such that it addition will result to zero;
3x - 8y = 7
(x +2y = -7)4
Then multiply the one equation with a constant (this case 4) to get;
3x – 8y = 7
4x + 8y = - 28
We add the two equations;
3x – 8y = 7
+
4x + 8y = - 28
=
7x = - 21
x = -21 / 7
x = - 3
Now we evaluate y by replacing the value of x with -4 in one of the equation;
x +2y = -7
-3 +2y = -7
2y = -7 + 3
2y = - 4
y = -2
