Answer:

A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875

Step-by-step explanation:

Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:

What is y=1/2x +2 y= -x +5 using subsitution
horsena [70]
Y=1/2x+2
y=-x+5
subsitute since they both equal y
1/2x+2=y=-x+5
1/2x+2=-x+5
subtract 2 from both sides
1/2x=-x+3
multiply both sides by 2
x=-2x+6
add 2x to both sides
3x=6
divide both sides by 3
x=2
subsitue
y=-x=5
y=-2+5
y=3

x=2 and y=3
solution in (x,y) form is (2,3)

(x-9) (x+3)

Then equal the parts of the binomial to zero


x - 9 = 0

x + 3 = 0
