The answer is 20x + 5y = 50
If u move the 20x over u get:
5y=-20x + 50
Solve for y by divided by 5
This gets y=-4x + 10
Now the answer is in slope intercept form: the -4 is the slope and 10 is the y-intercept
4.15, 6.3, 8.45, 10.6, 12.75
You just subtract 4.15 from 6.3 and you get a difference of 2.15. Then you add it to 8.45 giving you the answer of 10.6 and then you add 2.15 to that getting 12.75.
1. 56 : 35 = 1.6
2. 1.6* 100 = 160
3. The answer is 160
375 g. You have to set up a proportion and cross multiply.
Only a sample of the blue jay population was measured because it would be impossible to measure the entire population. The population of blue jays is all of the blue jays in the world. It would not be possible to measure all of them.
