Answer:

18x

Step-by-step explanation:

Since all 3 are monomial terms with the same variable, we can add them together:

5x + 3x = 8x + 10x = 18x

Answer: 18x

Explanation: The three parts of this expression, +5x, +3x, and +10x are called terms and the numbers in front of the variables, +5, +3, and +10 are called coefficients.

Because the variables, x, x, and x are identical,

the three terms in this problem are called like terms.

Like terms can be added together

by simply adding their coefficients.

So in this problem, since 5 + 3 + 10 is 18, 5x + 3x + 10 is simply 18x.

The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher

Romashka [77]

Answer:

$y = -0.1x^2 + 250 ft$

Step-by-step explanation:

Because this quadratic equation would have the curve-down form of:

$y = -ax^2 + b$

where a and b are positive coefficient.

If we let the peak (250 ft) of the curve be at x = 0. Then

$y = -a0^2 + b = 250$

$b = 250$

Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have

$-a(\pm 50)^2 + 250 = 0$

$-a2500 = -250$

$a = 250/2500 = 0.1$

Therefore, the model quadratic equation of our path would be

$y = -0.1x^2 + 250 ft$

Cedric and Josh both ordered the same size pizzas at Marco’s Pizzeria; however, they ordered different toppings. Marco’s charges

Oksanka [162]

Let
C---------> the cost of a pizza
t----------> number of toppings

we know that
$15.74-3t=$14.49-2t
15.74-14.49=3t-2t-------------> t=1.25

the cost of one topping is $1.25
and the cost of one pizza without topping is
15.74-3*1.25--------> $11.99

then
an equation for the cost of a pizza, C, as a function of the number of toppings, t ordered is
C=11.99+1.25t

the answer is
C=11.99+1.25t
