Answer:
<A =21
<B = 84
<c = 75
Step-by-step explanation:
<A =x
<B = 4x
<C =5x-30
The sum of A+B+C = 180
x+ 4x + 5x-30 = 180
Combine like terms
10x -30 = 180
Add 30 to each side
10x-30+30 = 180+30
10x = 210
Divide by 10
10x/10 = 210/10
x= 21
Since x =21 we can find the value of the angles
Substituting x into the equations for angles A, B and C
<A =21
<B = 4x = 4*21 = 84
<C = 5x-30 = 5*21-30 = 105-30 = 75
Answer:
No
Step-by-step explanation:
6a + 12 =? 3(3a + 4)
Distribute
6a+12 =? 3*3a + 3*4
6a+12 =? 9a +12
No
The expressions are not equivalent
Answer:
D
Step-by-step explanation:
when there are exponents with same bases multiplied by each other, keep the base and add the exponents
4^(3)+4^(5)=4^8
4^8 is D in this question
Answer:
9.2/5= C
Step-by-step explanation:
7.2- 3C = 2C -2 First, add the 2 on the other side to isolate 2C on one side
+2 +2
9.2 - 3C = 2C Next, add 3C to the other side
+3C +3C
9.2 = 5C Finally divide both sides by 5 to find the value of C
9.2/5= 5C/5
9.2/5 = C by dividing by 5 the 5 cancels out and you're left with the C value
