Answer:
x=2
Step-by-step explanation:
7x - 3 = 11
Add 3 to each side
7x - 3+3 = 11+3
7x = 14
Divide by 7
7x/7 = 14/7
x = 2
0.674 means that it 674/1000
which mean that if the model consists of 1000 squares, you have to shade 674 of the squares.
If the model consists of 500 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)
The correct answer is 66.
Xt-3=y
Move three to the other side as a positive number
xt=3+y
Divide everything by x
t=3+y divided by x
