Step-by-step explanation:
By substituting x = 0.4 in equation 7 + (-3x^2)
= 7 - 3 (0.4)^2
First solving o.4^2 as per the rule of BODMAS
= 7- 3 (0.16)
Now multiplying -3 with 0.16
= 7 - 0.48
= 6.52 THIS IS THE ANSWER
John sold 18 general admission tickets and 11 VIP tickets.
Step-by-step explanation:
Given,
Cost of each general admission = $50
Cost of each VIP ticket = $55
Total tickets sold = 29
Total revenue generated = $1505
Let,
x represent the number of general admission tickets sold
y represent the number of VIP tickets.
x+y=29 Eqn 1
50x+55y=1505 Eqn 2
Multiplying Eqn 1 by 50
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 5
Putting y=11 in Eqn 1
John sold 18 general admission tickets and 11 VIP tickets.

Answer:
At 25 weeks Quert will have more pibs than Gespil.
The measure of the smaller angle is 30 degrees.
The measure of the larger angle is 150 degrees.
What I did:
supplementary angle=180 degrees.
<span>An angle is five times its supplement=180/6=
30
30*5=150
150+30=180
