Answer:

[6x] + [-7y] + [-4]

Step-by-step explanation:

There are only two like terms in this expression "4x" and "2x." Since they are like terms we can combine them by adding the coefficients and keeping the variable attached. Therefore we can combine 4x and 2x into 6x. Since there are no more like terms, this expression can be simplified to 6x - 7y - 4.

Answer:

6x - 7y - 4

Step-by-step explanation:

4x - 7y + 2x - 4

Combine like terms (by either subtracting or adding a number with the same variable)

4x + 2x = 6x

Thus, only one like term so the final answer is

6x - 7y - 4

Find the perimeter of this semi-circle with diameter, d = 18cm. Give your answer as an expression in terms of pi.

OLga [1]

Answer:

The perimeter of the given semi-circle in terms of $\pi$ is

$P=9\pi$ cm

Step-by-step explanation:

Given that the diameter of the semi-circle is 18cm

That is d=18cm

Therefore radius $r=\frac{d}{2}$

$r=\frac{18}{2}$

Therefore radius r=9cm

To find the perimeter of the semi-circle :

perimeter of the semi-circle $P=\pi r$

$P=\pi\times 9$ cm (where r=9 cm )

$P=9\pi$ cm

The perimeter of the given semi-circle in terms of $\pi$ is

$P=9\pi$ cm

A map of a highway has a scale of 2 inches equals 33 miles. The length of the highway on the map is 6 inches. There are 11 rest

vfiekz [6]

Answer:

The answer is "0.975"

Step-by-step explanation:

Please find the complete question in the attched file.

Find the remaining distance inside the original map

$\to \frac{9}{6}=1.5 \ in$

Dividing the value by 6 because there are 7 rest stop:

$\to \frac{2 \ inches}{39 \ inches} =\frac{1.5 \ inches}{x \ miles}\\\\\to x=39 \times \frac{1.5}{2}\\\\\to x=29.25 \ miles$

Finding the diatance of the rest stop in the new map

Using proportion:

$\to \frac{1 \ inches}{30 \ miles} =\frac{x \ inches}{ 29.25 \ miles}\\\\\to x= \frac{29.25}{30}\\\\\to x=0.975 \ in$

If 2s +10r = 2(2s-5r) = 42, then what is the value of r?

Lesechka [4]

R=7/5
You can list two equations:
2s+10r=42 and 4s-10r=42.
Then try to delete S, you will get r
