Answer:

-35

Step-by-step explanation:

Adding 13 to both sides, you get:

35+4a= 3a

Then, you can subtract 4a from both sides to get:

35=-a

Finally, you need to multiply both sides by -1:

a=-35

Hope this helps!

How would I work this question? x+10y= -9 and x=5y+21

MatroZZZ [7]

Answer:

what you do is you want to get the x by it self so you would subtract the x and put it on the other side. like this: 10y=-9-x. OK so you would subtract -9 and put it on the other side like this: 9 + 10y=-x. but you can't have a negative x so u would do -9 + 10y=x.

Georgia [21]

Answer:

There are 68 dogs in the pound.

Step-by-step explanation:

Number of pit bull dogs in a pound = P = 23

Number of chihuahuas dogs in a pound = C = 17

Number of mutts dogs in a pound = M = 28

Total number of dogs in a pound = T

$T = P+C+M=23+17+28=68$

There are 68 dogs in the pound.

Please help me idk this

First take the fractions and find their common denominator:
$\frac{1}{2}$ x 4 = $\frac{4}{8}$

Now you can add the fractions:
$\frac{4}{8} + \frac{1}{8} = \frac{5}{8}$

Now add your whole numbers and the fraction:
1+1= 2 >> 2+ $\frac{5}{8}$ = 2 $\frac{5}{8}$ yards

Now subract 2 $\frac{5}{8}$ from 5:
5-2 $\frac{5}{8}$ =2 $\frac{3}{8}$ yards
