Is should be c and a if not just c
Answer:
B. False, they could be vertical angles
Step-by-step explanation:
Supplementary just mean when two angles form 180° (a straight line).
So ∠F and ∠G must form a straight line, and ∠G and ∠H must form a a straight line.
I drew the image out below and as you can see, angle F and H forms a vertical angle. A vertical angles is when two lines cross, the opposite angles from each others are called vertical angles.
Answer:
17.5% of 360 = 63
Step-by-step explanation:
We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.
17.5% can be break down as 10% + 5% + 2.5%
Thus,
STEP 1 : Find 10% of 360 , we get,

STEP 2 : find 5% of 360, we get,

STEP 3: find 2.5% of 360 , we get,

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360
⇒ 17.5% of 360 = 36 + 18 + 9
⇒ 17.5% of 360 = 63
Answer:
-52 / 5
Step-by-step explanation:
3 9/10 * -8 / 3 = 39 / 10 * -8 / 3 = -52 / 5
Answer:
Adult ticket: $7
Child ticket: $2
Step-by-step explanation:
Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:
2a + 3c = 20
a + 4c = 15
Solve by elimination by multiplying the bottom equation by -2:
2a + 3c = 20
-2a -8c = -30
Add them together:
-5c = -10
c = 2
Now, we can plug in 2 as c to find the value of a:
2a + 3c = 20
2a + 3(2) = 20
2a + 6 = 20
2a = 14
a = 7
