95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
Answer:
1 and two-thirds x + 35 minus 1 and one-half x + 12
1 and one-third x + 35 minus 1 and one-half x minus 12
One-sixth x + 47
Step-by-step explanation:
The original expression in the problem is
We need to expand this expression. First, we apply the distributive property and we multiply each of the numbers outside the bracket by each term in the brackets:
Now we can rewrite this expression in several ways. For instance, we can rewrite the two fractions as mixed fractions, and we get:
Also as
And now we add together the similar terms (those in x and those without x), and we find:
So the three options are
1 and two-thirds x + 35 minus 1 and one-half x + 12
1 and one-third x + 35 minus 1 and one-half x minus 12
One-sixth x + 47
Expression of volume = 1/3 × pi × radius
(squared ) × height
radius = diameter / 2
Answer:
SAS
Step-by-step explanation:
Sas states that if two sides and the angle of one triangle are congruent to two sides and the include angle of another triangle, then these two triangle are congruent.
