70 is 40% of what number? ________ 16 is 25% of what number? ________ 18 is what percent of 60? ________ 12 is what percent of 96? ________ 5% of what number is 25? ________ 20% of what number is 90?________ What percent of 55 is 22? ________ What percent of 75 is 15?________ 24 is 60% of what number? ________ 30% of what number is 4?________ Review: Graph.Solve for x. x > -2 3x - 3 = 15
Answer:
I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.
Step-by-step explanation:
A line passes through the point (4.3) and has a slope of 3/2.
Find the equation of the line
A. y = -3/2x - 3
B. y = -3/2x - 9
C. y = 3/2x -3
D. y = 3/2x - 9
Answer:
The y-intercept is positive 15
Step-by-step explanation:
Answer: y=3/2x-3, Option C
Step-by-step explanation: First off, plug this information in to the point slope form equation: y-y1=m(x-x1) then solve for y. The m would be the slope, 3/2. The point (4,3) the x1 = 4, the y1 = 3. So plugged in the equation would be: y - 3 = 3/2 (x - 4). Then distribute and add 3 to both sides to solve for y.
