Answer:
x=1.3288 or -1.1288
Step-by-step explanation:
Given 
Subtract 4x from both sides
Since we can factor out 2 from whole equation, let's factor out 2.
Divide with 2 on both sides
We got the quadratic equation, we can solve for x using quadratic formula.
the answer is B because to get the total cost, first divide 450 by 50. This gives us 9. We then multiply 9 by $600 to get a total of $5400.
Answer:
54.26
Step-by-step explanation:
0.4+0.86= 1.26
51+2= 53
53+1.26= 54.26
Can't without a picture :/
I assume you are asking one of three things, so I will answer all of them.
if you are asking what is 1/2 of 312, then multiply 312 by 1/2. 312 is really just 312/1, so
we multiply fractions by multiplying straight across
if you were asking what part of 3 1/2 is 1/2 then we have to recognize what 3 1/2 is as an improper fraction. to do this, we convert 3 into halves. how many halves of pizza are there in 3 whole pizzas? 6. so we have 6 halves and one half, which is a total of 7 halves.
now, we do the same thing as the first problem
if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply
