9x + 36 = 8x - 3
solve for x.
x + 36 = -3
x = -39
2 = 25%. 25% also means 1/4. So, it is a quarter of something. So. So find 100%, you have to multiply 2 by 4. 2 * 4 = 8. Roman has 8 pencils in his backpack.
Y=mx+b
y=-2/12x-8
Simplify:
y=-1/6x-8
Slope intercept is really easy. m is the slope. All you have to do is find 2 points and use rise/run. Rise is how many up or downs (numerator). Run is left or right (denominator). We are given 2 points in the graph. So I counted, 2 down, 12 left. So 2/12. Now remember if the line is going down from left to right, it’s a negative slope. So -2/12. To find the y intercept, just find where the line meets at the y intercept, here it’s -8. So y=-2/12x-8. y=-1/6x-8
Answer:
$28.82
Step-by-step explanation:
Since we are adding a 13% tax, we multiply 25.50 by 1 plus .13:
25.50(1 + 0.13)
25.50(1.013)
28.815
Alternatively, we could multiply 25.50 by 0.13 and then add the results:
25.50(0.13) = 3.315
25.50 + 3.315 = 28.815
