Step-by-step explanation:
Answer:
0.9x
Step-by-step explanation:
you just subtract the two
Answer:
The sum of all the sides to this quadrilateral will equal a total of 20 inches, so you set up the equation:
2 + 2x + 7 + x + 2 = 20
Solve for x by combining like terms;
(2 + 7 + 2) + (2x + x) = 20
Which simplifies to;
11 + 3x = 20
Get rid of constants;
-11 -11
3x = 9
Isolate x by getting rid of it's coefficient;
/3 /3
<u>x = 3</u>
Now, to find the length of PQ, we plug in the value of x(3) into the equation that contains the line PQ.
x + 2
<u>3</u> + 2
= <u>5 inches.</u>
Now, to find the length of RS, we plug in the value of x(3) into the equation that contains the line RS.
2x
2(3)
= <u>6 inches.</u>
Answer:
d + c = 122
d - 5 = 2c
so same as saying
2d + 2c = 244
we plug in for 2c
2d + d - 5 = 244
2d + d = 249
3d = 249
d = 249 / 3
d = 83
since d - 5 = 2c
83 - 5 = 2c
78 = 2c
c = 39
there are 39 cats and 83 dogs
39 + 83 = 122
