Answer:
(nearest tenth)
Step-by-step explanation:
Given the distance formula, , distance between (-4, 5) and (4, 0) is calculated as follows:
Let
(nearest tenth)
It's a simultaneous equation:
Steps:
1.Number the equations..
a+b=77 -1
a-b=13 -2
2. Choose what variable you want to use. In this case I would use the "b". Since the signs in front of the "b's" are different, add the two equations together
a + b = 77
+ + +
a (-b) = 13
Which gives;
2a = 90
Then solve to find a:
2a=90
a= 90/2
a=45
3.Then plug the "a" value into any of the original equations to find the "b" value. I would use equation 1 since the all the variables are positive.
a + b = 77
(45) + b = 77
b=77-45
b=32
4.Solution
a=45
b=32
Answer:
P=8h
Step-by-step explanation:
P is the total amount of dollars that Keith will make, while h is the number of hours he will work for. If you multiply the number of hours he works for and how much he makes in an hour which is 8. You will get the total amount.
Answer:
There is no image.
Step-by-step explanation:
Can you add a image or something because You did not give a "line below"
You can divide both numbers by 6 to get 2/15 (which cannot be simplified anymore)
2/15 is the simplified form
