Answer:
18 and 11/16
Step-by-step explanation:
I converted the two numbers into improper fractions which leaves me with
71/8+157/16
I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:
142/16+157/16
I can now add the 2 numbers together and I get:
299/16
now we just need to convert the number into a mixed number by dividing, and I am left with:
18 and 11/16
Answer:b
x=3-y/7
Multiple 7
7x=3-y
Subtract 3
7x-3=-y
Times both sides by negative 1
-7x+3
To find x:
Subtract 10 on both sides.
10 + 2x = 90
-10 -10
Divide 2 on both sides.
2x = 80
--- ---
2 2
This would get x alone.
x = 40
Check:
10 + 2(40) = 90
10 + 80 = 90
90 = 90
The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
Answer:
y = - 3/2x
Step-by-step explanation:
point (x , y)
point (2 , -3)
m = y/x
m = -3/2
Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
