C-7=7
Cancel out the -7 so add 7 to both sides
C-7=7
+7=+7
C=14
M-7=-7
Same thing
M-7=-7
+7=+7
M=0
X+5=-10
-5=-5
X=-15
Y+8=3
-8=-8
Y=-5
9k=-18
This time divide 9 on both sides
9k=-18
\9=\9
K=-2
-3v=-7
/-3=/-3
V=7/3
5n=-15
/5=/5
N=-3
T/2=-6
*2=*2
T=-12
D/-4=-2
*-4=*-4
D=8

Step-by-step explanation:

1/2 represents every fraction, where the denominator (bottom part) is twice the numerator (top part).

like 4/8 or 6/12 or 128/256 or ...

what do we need in the denominator to calculate with 15/16 ?

the same : 16.

and what is half of 16 ? 8.

so, we need the 1/2 based on 16th = 8/16.

so, the dog ate 8/16 (1/2) of the original 15/16.

what was left was

15/16 - 8/16 = 7/16 pound

the perimeter of a rectangular field is (16a+8b-6c) units and one of its side is (5a+3b-4c) find the other side
Jet001 [13]

3a+b+c


The perimeter is two times one side (to account for the opposite) and two times the adjacent side. So if the sides would be x and y, the perimeter would be 2*x + 2*y.

So, knowing that the sum is 16a+8b-6c, if we subtract the given side 5a+3b-4c from this, what remains is two times the "other" side:

16a+8b-6c - 2*(5a+3b-4c) =

16a+8b-6c -10a-6b+8c =

6a+2b+2c

half of that is

(6a+2b+2c)/2 = 3a+b+c

I don’t know how to simplify this equation
yanalaym [24]

Answer:

7^5

Step-by-step explanation:

According to the Product Rule for Exponents, \frac{a^m}{a^n} = a^{m-n}

a = 7

m = 9

n = 4

So,

\frac{7^9}{7^4} = 7^{9-4} = 7^5

So, the answer is 7^5.

Hope this helps!!!
