For the first one a=4 cuz 4x4=16
Answer:
x=3
Step-by-step explanation:
If k is between J and L, then
JK + KL = JL
2x+11 + (3x) = 13x-13
Combine like terms
5x +11 = 13x -13
Subtract 5x from each side
5x-5x+11 = 13x-5x-13
11 = 8x-13
Add 13 to each side
11+13 = 8x-13+13
24 = 8x
Divide by 8
24/8 = 8x/8
3 =x
3(4)+6
12+6
The answer is 18
25 times 8.14 is $203.50 so there’s your answer
1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10
so it's 25m^2/10minutes
now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours)
25*12=300
answer is 300m^2
hope this helped
