x=number of talk mnutes
Sage uses 7 minutes = x-7
Tom uses 4 and 3 minutes = x-4-3 = x-7
First of all, 2400=0.6x is the equation
Now, we use cross multiplication
2400/1 = 3/5x
2400*5 = 3x
12,000 = 3x
12000/3= 4000
<u>The total fundraiser goal is $4,000.</u>
The equation of a circle:
(h, k) - a coordinates of the center
r - a radius
A diameter d = 2r
We have
Answer: d = 2 · 10 = 20
The number of people who bought £4 tickets are 139.
<h3>How to illustrate the equation?</h3>
Let £4 tickets be x
Let £5 tickets be y.
Therefore based on the information given, this will be:
x + y = 223 ..... i
4x + 5y = 936 ..... ii
From equation i
x = 213 - y
Put this into equation ii
4x + 5y = 936
4(213 - y) + 5y = 936
852 - 4y + 5y = 936
Collect like terms
y = 84
This implies that the number of £5 tickets is 84.
Recall that x + y = 223
x + 84 = 223
x = 223 - 84
x = 139
The number of £4 tickets is 139
