Answer:
Step-by-step explanation:
Estimating a sum by rounding to get the best estimate is the goal of this lesson. Notice that we try to estimate. We don't need to have an exact answer!
Notice that for numbers with two digits, there can only be one estimate because you can only round to the tens place.
Estimate the following sums: 36 + 21, 74 + 15, and 85 + 24
36 + 21 = 40 + 20 = 60
74 + 15 = 70 + 20 = 90
Answer:
Some number divided by 4
Step-by-step explanation:
The y stands for an unknown number, aka some number. The slash indicates division, so it would be some number divided by 4.
Answer:
I can't post a graph, but I will explain how to do it.
Step-by-step explanation:
The y intercept is 3, so we know we can place a point at the coordinates (0,3). The y intercept is the point where your line crosses the y axis.
The slope is -3, which is the same as -3/1. The top number is the y axis, the bottom number of the slope is the x axis. This tells us that for every 1 space we move on the x axis, we move -3 spaces on the y axis. You should therefore have a second point located at (1,0).
You should end up with a line with a point at (0,3) and (1,0) which slopes down from left to right. Hope that helps.
