number 3 is not congruent but number 4 is because #4 is basically the same thing but you cant really multiply something to question #3 to get those answers.
Answer:
9
Step-by-step explanation:
The equation is
9x + 1.50 = 82.50
You must isolate the 9x , to do so you have to subtract 1.50 from both sides.
9x + 1.50 = 82.50
-1.50 -1.50
9x = 81
isolate the variable (x), to do so you have to divide both sides by 9
9x = 81
/9 /9
=
x = 9
Is this the full question? I’m confused.
Answer:
5.6
Step-by-step explanation:
let ‘x’ denotes the weight of smaller dog.
“1.4″ + x” be weight of larger dog
combined weight = 12.6
smaller dog weight =
x+x+1.4 = 12.6
2x + 1.4 = 12.6
2x = 12.6–1.4
2x = 11.2
x = 11.2/2
x = 5.6
Answer:
Volume of square and rectangle:
L*W*H
square:
12*6*12 = 864 inches
rectangle:
18*8*10 = 1,440 in
Add
1,440 + 864 = 2,304 in^3
