Answer:
<em>Henson: 3x + y = 163</em>
<em>Garcia: 2x + 3y = 174</em>
<em>adult ticket price: $45</em>
<em>child ticket price: $28</em>
Step-by-step explanation:
Henson Family:
3 adults + 1 child; total $163
3x + y = 163
Garcia Family:
2 adults + 3 children; total $174
2x + 3y = 174
Now we solve the system of equations.
Solve the first equation (Henson Family) for y.
y = 163 - 3x
Substitute 163 - 3x for y in the second equation (Garcia Family).
2x + 3<em>y</em> = 174
2x + 3(<em>163 - 3x</em>) = 174
2x + 489 - 9x = 174
-7x + 489 = 174
-7x = -315
x = 45
Now substitute 45 for x in the first original equation and solve for y.
3x + y = 163
3(45) + y = 163
135 + y = 163
y = 28
adult ticket price: $45
child ticket price: $28
Answer:
5 + 40 d
Step-by-step explanation:
Hey there,
To simply this you have to multiply each term in the brackets by 5.
<u>Further explanation</u>
5 ( 1 + 8 d )
5 × 1 + 5 × 8 d
5 +40 d
Hope this helps you.

Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question
example: So let we are given a polynomial function as:
and we are aksed to evaluate this polynomial at 
Then the value of the polynomial will be:
Hence on evaluating the polynomial function f(x) at we get the value of the polynomial function as 
.
Answer:
Answer is y =400(2x)
Step-by-step explanation:
If the tax rate is 8%, we need to find 108% of the price, or 330 times 1.08, which is $356.4
