Answer:

c(-10)

Step-by-step explanation:

move all terms to left

(C)(c)-(2.5c+15)=0

get rid of perentheses

c-2.5c-15=0

we add numbers together and all variables

-1.5c-15+0

we move all terms containing c to the left all other terms to the right

-1.5c=15

c=15/-1.5

c=-10

Komok [63]
Y-y1 / x-x1 to get slope
5 - 1 / 9 - 4
m (slope) = 4/5
plug in one point to get b
1 = 4/5(4) + b
1 = 16/5 + b
b = -15/5
y = 4/5x - 15/5

Write a mathematical sentence that expresses the information given below. Use b as your variable name. If necessary:
ra1l [238]

The number of books owned by frank is represented as b < 150

<h3>What is inequality?</h3>

Inequality represents the form of writing expressions where the left hand side of the expression is not exactly equal to the right hand side of the expression

<h3>How to represent the required expression</h3>

Information gotten from the data include

Emily has 300 books

Frank were to double the number of books that he now owns, he would still have fewer than Emily has.

Let the number of books owned by frank be b and from the information we have that:

2b < 300

b < 150

hence the number of books owned by frank, b less than 150

Ac-ab=2 solve for a. please someone can help me . thanks
vazorg [7]
Ac - ab = 2

Factor out a

a(c-b) = 2

Then divide the expression by c-b to solve for a.

Do this on both sides.

a(c-b)/(c-b) = 2/(c-b)

a = 2/c-b

The solution is a = 2/c-b.
