Answer:

36.5

Step-by-step explanation:

y= -x²+73x-520

which can be represented as ax²+bx+c

a= -1, b= 73, c = -520

for maximum value of y,

the formula is

c - (b² / 4a)

= -520 - (73² / 4×(-1))

= -520 - (5329 / -4)

= -520 + 1332.25

= 812.25

Solving for x,

812.25 = -x²+73x-520

or, x²-73x+ 1332.25 = 0

Solving,

x= 36.5

marishachu [46]

Given:

The given term is 3x.

To find:

The like terms.

Solution:

Like terms are the terms which contain same variable and degree.

In the given term 3x, the variable is x and its degree is 1.

The variable in 4y is y and, 8 and 0.257 are constant. So, 4y, 8, 0.257 and 3x  are not like terms.

On 10 has variable x and degree 1. So, 3x and 10x are like terms.

Therefore, the correct option is B.

Help!!!!!!! Thank you!!!!!!!
kvasek [131]

Answer:

D

Step-by-step explanation:

The ratio of yellow paint to blue paint is 4:3. We can make the largest amount of green paint by using all of the 20 quarts of yellow paint so we have to solve for x in 4:3 = 20:x, since 4 * 5 = 20, 3 * 5 = x so we use 15 qts of blue paint, therefore we will have 20 + 15 = 35 qts of green paint.
