Answer:
Step-by-step explanation:
2) 8=n+3/-2
we cross multiply
n+3=8*(-2)
n+3= -16
n= -16 - 3
n= -19
lets check if we are correct
8=-19+3/-2
8= -16/-2
-16/-2=8
4) 9=x/2+6
we first calculate the fraction
x/2+6
L. c. m is 2
x/2+6/1=4x + 8/2=12x/2
2 times 2=4 plus x = 4x
2 times 1 =2 plus 6= 8
thats how i got 4x + 8/2
back to the question
9=12x/2
cross multiply
12x=9*2
12x=18
x=18/12
we will use 2 to divide it
9/2
3 will divide
3/2
x=3/2
A) 20.93%
B) 20%
C) 59.07%
Explanation
A) The total area of the rectangle is 6(10) = 60 ft². The area of the circle is 3.14(2²) = 12.56. This makes the probability of hitting the circle is 12.56/60 = 20.93%.
B) The total area of the rectangle is 60. The area of the trapezoid is 1/2(2+4)(4) = 12 ft². This makes the probability of hitting the trapezoid 12/60 = 20%.
C) The areas of the circle and trapezoid together are 12+12.56 = 24.56. This makes the rest of the area 60-24.56 = 35.44. This gives us the probability of not hitting the circle or trapezoid 35.44/60 = 59.07%
You have to plug in 7 for f and 8 for k making it look like -5(7)-2+8-3(8), now multiply to get the further more, -35-2+8-24, now add or subtract to get -53
Hope this helps
Answer: Our required answer will be

Step-by-step explanation:
Since we have given that

We need to get the difference:
1) We first open the second bracket and make appropriate change in signs :

2) Gather the like terms together :

Hence, our required answer will be

625 because 1250 divided by 2 is 625
