45 adult tickets were sold.
adult tickets = a
childrens tickets = b
a + b = 65
6a + 3.5b = 340
Subtract a from the equation on top to get b = 65 - a
Substitute into the second equation 6a + 3.5(65 - a) = 340
Simplify to make 6a + 227.5 - 3.5a = 340
6a - 3.5a = 340 - 227.5
Combine like terms so that 2.5a = 112.5
Divide both sides by 2.5 to isolate the variable a
Your final answer is a = 45
Answer:
Step-by-step explanation:
25x = 300
Rearrange to solve
x = 300 divided by 25 = 12
Hope this helps
Answer:
y = 2x +5
Step-by-step explanation:
1. use slope intercept for y2 - y1 / x2 - x1 --> 7-(-12) / 1-(-5)
2. solve --> 7-(-12) / 1-(-5) = 2
3. put in slope (2) and a coordinate into equation --> y = mx + b --> 7 = 2(1) + b
4. solve --> 7 = 2(1) + b --> b = 5
5. put the equation together --> y = 2x + 5
H=k/t where k is the constant of proportionality
2=k/70
k=140
The possible value of y are 16, 32 and 64
<h3>How to find the values of an
exponential table?</h3>
The table above is an exponential table.
Therefore, let's confirm the ratio of the y axis.
8 / 4 = 2
4 / 2 = 2
Therefore, the other y axis can be gotten as follows:
y = 8 × 2 = 16
y = 16 × 2 = 32
y = 32 × 2 = 64
y = 64 × 2 = 128
Therefore, the possible value of y are 16, 32 and 64
