Answer:
x = 1
Step-by-step explanation:
It is given that,
∠A and ∠B are vertical angles.
∠A = (5x – 4) and ∠B = (2x – 1)
We need to find the value of x.
We know that, the vertical angles are equal. So,
∠A=∠B
(5x – 4)=(2x – 1)
Taking like terms together,
5x-2x = 4-1
3x=3
x = 1
So, the value of x is equal to 1.

Amy bought some shirts and skirts for $168. Each shirt cost $17, and each skirt cost $22. She
bought a total of 9 items. How many shirts did Amy buy
Answer:
3 shirts and 6 skirts
Step-by-step explanation:
lets call number of shirts x and number of skirts y
so x+y=9
17x+22y=168
multiplying the first equation by 17 we get
17x+17y=153
17x+22y=168
subtracting we get
5x= 15
x=3
and we know x+y=9 so y=6
so 3 shirts and 6 skirts

Enter the value for x that makes the equation true.
Answer:
Step-by-step explanation:
⅔(x-6) = ¾(x+16)
Multiply both sides by 12
8(x-6) = 9(x+16)
8x - 48 = 9x + 144
x = -192
