Hi there.

10a - 35 = -8a + 1; get the variable to one side, so add 8 to both sides.

18a - 35 = 1; add 36 to both sides so we can isolate the variable.

18a = 36; divide both sides by 18 to solve for the variable.

a = 2

I hope this helps!

First start with combining and collecting like terms on different sides. So 10a+8a=35+1. 18a=36. Divide a=36/18. a=2.

Answer:

B. 236.3

Step-by-step explanation:

Population density can be found by dividing the number of people by the area of the land.

number of people / land area

The population is 20,510 people and the area is 86.8 square miles.

20,510 people / 86.8 square miles

Divide 20,510 by 86.8

236.290323 people /square mile

Round to the nearest tenth. The 9 in the hundredth place tell us to round the 2 to a 3 in the tenth place.

236.3 people/ square mile

There are 236.3 people per square mile and B is correct.

jamie wants to run a total of 9 miles thid week. so far, she has run 4 5/8 miles. use the equation 4 5/8 + r = 9. please help m

____ [38]

Answer:

$r=4\frac{3}{8}$

Step-by-step explanation:

Given the following question:

$4\frac{5}{8} +r=9$

<u>Rewrite the expression to find the value of r:
</u>
$9-4\frac{5}{8}$

<u>Subtract by finding the common denominator:</u>
$9-4\frac{5}{8}$
$9=\frac{9}{1}$
$4\frac{5}{8} =8\times4=32+5=37=\frac{37}{8}$
$\frac{9}{1} -\frac{37}{8}$
$\frac{9}{1} \times8=\frac{72}{8}$
$\frac{37}{8} \times1=\frac{37}{8}$
$\frac{72}{8} -\frac{37}{8}$
$72-37=35$
$=\frac{35}{8}$
$\frac{35}{8} =35\div8=4\frac{3}{8}$
$r=4\frac{3}{8}$
$4\frac{5}{8} +4\frac{3}{8} =9$

Hope this helps.

Can I make a right angle by drawing an acute angle and and an obtuse angle that share a common ray?

Trava [24]

Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
