Dont mind this its just to ask a question
∠6 is vertical to ∠5 and ∠7 is vertical to ∠8. If ∠6=∠7 then ∠5=∠8
Answer:
Option E
Step-by-step explanation:
We know that
√25 = 5
√36 = 5
√30 lies between √25 and √36.(5 and 6l
Hence, Option E is correct
Answer:
42
Step-by-step explanation:
If we suppose the value is constant,
Divide 30/5 we get 6.
so now we know for every 1 x we get 6 y.
Multiply 6 times 7 = 42.
The value of y = 42 when x = 7.
Answer: 8 First class tickets
Step-by-step explanation:
You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.
