Answer:
x = 7
Step-by-step explanation:
The proportion is
14/6 = 21/(3x - 12) Cross Multiply
14*(3x - 12) = 6*21 Remove the brackets and combine
42x - 168 = 126 Add 168 to both sides
42x = 126 + 168
42x = 294 Divide by 42
x = 294/42
x = 7
Answer: y=2x+4
Step-by-step explanation:
From the graph, we already know what the y-intercept is. The line crosses the y-axis at (0,4). Therefore, 4 is our y-intercept.
For the slope, we can take any 2 points on the graph and then use the formula to find slope. Let's use (1,6) and (2,8).
Now that we know the slope, we can fill in our slope-intercept equation.
y=2x+4
Toby should choose Project B because since there are equal number of the four colors of beads, you simply divide the total number of beads by four to get the number of one color of bead(re. green). 1020/4 = 255. Since Toby wants to use the project that uses an amount of beads under 260, Project B is the right choice.
