Answer:
x = 4.
Step-by-step explanation:
These are exterior alternate angles which are congruent.
So 21x + 6 = 90
21x = 84
x = 4.
Answer:
<STP=105°
Step-by-step explanation:
two interior angles equal one opposite exterior angle therefore
7x+6+7x+1=15x
group like terms
6+1=15x-7-7
7=15x-14x
7=x
for 15x
15 will multiply 7 and that is 105

Answer:
Option C is correct.
Step-by-step explanation:
Given Equation:

To find: Solution of the Equation.
Consider,





b² = 0 ⇒ b = 0
b - 4 = 0 ⇒ b = 4
Therefore, Option C is correct.
Answer:
$1.35
Step-by-step explanation:
x: quarter=$0.25
y: dime=$0.10
z: nickel=$0.05
so total amount of changes
= (0.25*x)+(0.10*y)+(0.05*z)
x=3, y=5, z=2
substituting into the eqn
total = (0.25*3)+(0.10*5)+(0.05*2)
= 0.75 + 0.5 + 0.1
= $1.35
