Answer: x=20
Step-by-step explanation:
63-x=2x+3
-x-2x+63=3
-x-2x=3-63
-3x=3-63
-3x=-60
-3x/3=-60/3
X=20
please mark me brainliest!!
Hi
The formula starts with x=9. So the formula would be x-3, than you get a different number and you fill x with that number do this over and over and you will get to -3 or even lower
Let x be quarters, and y be nickels.
0.25x + 0.05y = 11.50
x + y = 66
x= 66 - y
0.25(66-y)+0.05y=11.50
16.5 -0.25y+0.05y = 11.50
16.5-0.2y=11.50
-0.2y=11.50-16.5
-0.2y=-5
-0.2y/-0.22=-5/-0.2
y=25
x+y=66
x+(25)=66
x=66-25
x=41
So there are 41 quarters, and 25 nickels.
It's A) to find the slope.
The resulted equation is in slope-intercept form which gives the slope (-A/B).
