Answer:
63 / 0.9 = 70
Answer: The total point is 70
Step-by-step explanation:
Let x represent the total point of the test
90% of x = 63
90/100 × x =63
90x / 100 = 63
cross multiply
90x = 6300
Divde bothside by 90
90x / 90 = 6300/90
x = 70
Therefore the total possible mark is 70
The answer is 3+(-6) = -9, because -9 is 6 units to the left of 3.
87.5% are pennies
7/8 = 87.5%
Hope this helps!!
slope is y2-y1/x2-x1
-3-4=-7
-1-4=-5
now that you have -7/-5, or negative seven fifths, simplify.
you get -0.4, or -2/5 as your slope
