It's D)
you can subsitute any number you want for x and it'd still be a soloution to y=
<span>x=y+2
2y=x-1
substitute </span>x=y+2 into 2y=x-1
2y=x-1
2y=y+2 -1
2y - y = 1
y = 1
<span>x=y+2
</span><span>x=1+2
x=3
answer
x = 3 and y = 1</span>
Given :
Three points , P(4, 3, 4), Q(2, 1, 3), R(2, 7, 0) .
To Find :
The length of sides .
Given :
We know , length of two points P(x,y ,z) and Q(a,b,c) is given by :

Length of PQ :

Length of QR :
:
Length of RP :

Hence , this is the required solution .
Answer:
The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode. The largest value in the list is 7, the smallest is 1, and their difference is 6, so the range is 6.
Step-by-step explanation:
give that other guy a brainliest
Dory = 11 x Carly
Together => d + c = 156
11c + c = 156
12c = 156
C = 156 : 12
C = 13
Carly biked 13 miles
Dory = 11 x c = 11 x 13 = 143 miles
Prove
143 + 13 = 156 miles together
