The awer is 3 because the clock will be
Answer: x= 12 and MNQ= 25 degrees
3x - 11 + 65 = 90
3x + 54 = 90
3x = 36
x = 12
plug in the value of x to get MNQ
3(12) - 11
36 - 11
25
Answer:
since Sonia saved 45$ in 5 weeks and 70$ in 10 weeks. we are to find the amount she saved up in x weeks.
let's make the amount y
so x= y
5 = 45 cross multiplying the values
we then have 45x= 5y
y= 7x
x=y
10=70
10x = 70y
y= 7x = y=5x+ 20, y = 20x+5
