<span>1x + 2x = 15
3x = 15
3x/3 = 15/3
x = 5
Gemma = 1x, Zak = 2x therefore Gemma = 5 and Zak = 10</span>
Answer:
20
Step-by-step explanation:
0.4x = 8
0.4x/0.4 = 8/0.4
x = 20
Answer: y=1/2 - 3
Step-by-step explanation:
what they want you to find is the slope and y-intercept, and put that into slope-int form, which is y=mx+b. the point that is located on the y intercept is (0, -3), which gives you your b, which is -3. the other point on the graph helps you find the rise/run, or slope, which is m=2/4. simplified is m=1/2. so, y=1/2 - 3
