(2,11) would be the points where they intersect
Answer:
Step-by-step explanation:
we can use reciprocals to solve this
(5/32)/(25/4) = (5/32)*(4/25) = 20/(32*25) = 20/800 = 2/80 = 1/40 = .025
rewrite
so reciprocals is a method in which division can be turned into fractions which can be turned into multiplication
heres an example
x/2=0.5x
y/4=0.25y
so 0.5x/0.25y would be the same as (x/2)/(y/4) which can be converted to a reciprocal where it would look like (x/2)*(4/y) which makes our answer 4x/2y which we can simplify to 2x/y
same concept for (5/32)/(25/4), first we can make it into a reciprocal (note, reciprocal means just flipping one of the fractions and replacing the division sign as multiplication) by writing (5/32)*(4/25)
now we multiply numerator by numerator to get 20
and we multiply denominator by denominator to get 800
20/800 = 2/80 = 1/40
The probability is 0.1429.
The probability that the first person chosen is a boy is 5/7. The probability that the second is a boy is 4/6; the third, 3/5; and the fourth, 2/4. Both the numerator and denominator decrease every time, because you lose a boy to choose from and you lose a student to choose from as well. This gives us:
5/7(4/6)(3/5)(2/4) = 120/840 = 0.1429.
Answer:
y=-3 x=4
Step-by-step explanation:
y=3x+3
y=3x+3 y=x-1
+<u>1</u><u> </u><u> </u><u> </u><u> </u><u>+</u><u>1</u>
y+1=x
y=3(y+1)+3
y=3y+3+3
y=3y+6
<u>-3y=-</u><u>3y</u>
-2y=6
-y=3
<u>y=</u><u>-</u><u>3</u>
3=x-1
