Let x equal the # of child tickets
Let y equal the # of adult tickets
x + y = 84
3x + 5y = 360
Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.
x + y = 84
x = 84 - y
Now substitute the resulting expression into the other equation and solve for y.
3( 84 - y ) + 5y = 360
252 - 3y + 5y = 360
Combine like terms
252 + 2y = 360
Subtract 252 from both sides
2y = 108
Divide by 2 on both sides
y = 54
Substitute the value of y into the equation that we solved for x, x = 84 - y
x = 84 - 54
x = 30
Therefore the answer should be, 30 childrens tickets sold and 54 adult tickets sold.
Nine hundred thousands place
Answer:
d=100
Step-by-step explanation:
.99d=10 + .89d
subtract .89d from both sides
.1d=10
divide by .1 on both sides
d=100
to check plug in 100 in place of d
The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.
More about the domain and range link is given below.
