Since there are four suits, with each having a 4 and 5, we have 2+2+2+2=2*4=8
Here, 3t - 7 = 5t
5t - 3t = -7
2t = -7
t = -7/2
Then, 6t = 6(-7/2) = 3(-7) = -21
In short, Your Answer would be -21
Hope this helps!
If 24 students went on a field trip, and 24 students represented eight tenths of the class, then

.
First, multiply by 10 on both sides.
240 = 8x
Divide by 8 on both sides.
x = 30.
The class has 30 students in all.
This is, however, only the equation way to solve.
The last graph. This is because he can’t fold a paper a negative number of times, it’s impossible. Hope this helped :)
Answer:
2.
x=3 y=3
Step-by-step explanation:
3-3=0
3+3=6
If 3x-3y equals 0, then what's x+y. It concluded to 6
