1/2(10x +5) what is the value of the expression when x=1.4

Mathematics

Anon25 [30]3 years ago
3 0

Answer:

19.2

Step-by-step explanation:

Rewrite 1/2(10x +5)  as  (1/2)(10x +5) for clarity.

Next, substitute 1.4 for x:

(1/2)(10[1.4] +5)

According to rules of operation, work inside parentheses must come before all else.  Thus we obtain:

(1/2)(14+5), or (1/2)(19).  Finally, this simplifies to 19/2.

How do you write 16x-3y=3 in slope intercept form
serg [7]
Y=16/3 x -1

First, you minus both sides by 16x. This will get you -3y = 3 - 16x

Then, you divide both sides by -3. Hence on the right hand side you will get 3 - 16x over -3, which can be split into (-16x/-3) + (3/-3). By simplifying this you can get 16/3 x - 1.
