Answer:

1/10

Step-by-step explanation:

There are three simple fractions in this problem: 3/5, -1/4 and 7/10. Rules of order require that the division (-1/4) divided by 7/10 be carried out first; the correct product is -10/28, or -5/14. Then we have 3/5 + (-5/14).

Here the LCD is 70. Then 3/5 + (-5/14) becomes 42/70 - 35/70, which simplifies to 1/10.

Solve the system of equations by substitution

r-ruslan [8.4K]

We have y=2x and y=x+2
They both equal y, so substitute the first equation for y in the second equation.
2x=x+2
Let’s get x to one side. Let’s subtract x from both sides.
X=2
Since x=2, just plug in 2 for x.
2+2=4
So,
X=2
Y=4

Clayton Road is 2.35 miles long. Wood Pike Road is 1.7 miles long. Draw a quick picture to find the combined length of Clayton R

marysya [2.9K]

Answer:

4.05 miles.

Step-by-step explanation:

See the attached diagram. (not in scale)

Let AB is the Clayton Road and its length is 2.35 miles and BC is the Wood Pike Road and it is 1.7 miles long.

So, the combined length of Clayton Road and Wood Pike Road is AC (= AB + BC)

So, the length of AC will be (2.35 +1.7) miles = 4.05 miles. (Answer)
