Explain hovevou could estimate 22% of 78 to check if your answer is reasonable.

Mathematics
1 answer:
fomenos2 years ago
8 0

Answer:

78 rounds to 80, so find 10% of 80 and double it. 10% of 80 is 8. So, 20% of 80 is 16. Then, 22% of 78 is a little more than 16.

78 rounds to 80, and 22% is a little less than 25%. 25% (or one-fourth) of 80 is 20. So, 22% of 78 is a little less than 20.

Here is a system of linear equations:
marysya [2.9K]
5x+4y=16 y=3/5x-3

y=mx+b <------ slope-intercept form

5x+4y=16
-5x       -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4

Slope is -5/4
y-intercept is 4

y=3/5x-3

slope is 3/5
y intercept is -3

I can't do the graph but I'm sure you can figure it out!
Hope I helped.
