1/2 + 1/3 = 3/6 + 2/6 = 5/6
we have 5/6 so 15 is 1/6 of the entire group
15 × 6 = 90
Answer:
x = 3.8
Step-by-step explanation:
0.18(5x – 4) = 0.5x + 0.8
→ Expand out 0.18(5x – 4)
0.9x - 0.72 = 0.5x + 0.8
→ Multiply everything by 100 to get rid of the decimals
90x - 72 = 50x + 80
→ Minus 50x from both sides to collect the x terms
40x - 72 = 80
→ Add 72 to both sides to isolate 40x
40x = 152
→ Divide both sides by 40 to isolate x
x = 3.8

Answer:
y -2 = 1/4(x +3)
Step-by-step explanation:
Process: find the negative reciprocal of the slope of the line shown and put the appropriate values into the point-slope equation.
__
The slope of the given line can be found as the ratio of rise to run between the marked points.
m = rise/run = -8/2 = -4 . . . . counting grid squares
The desired line has a slope that is the opposite reciprocal of this:
m' = -1/m = -1/-4 = 1/4
The point-slope equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Then the desired line with slope 1/4 through point (-3, 2) has equation ...
y -2 = 1/4(x +3)
