The length is 17 and x=5
13 times 3x+2 = 221 so solve by dividing 221 by 13= 17.
Now we know that 3x+2= 17 so 3x= 15
x=5
One number is 26 the other is 23
x+y=49
Y=x+3,X (now substitute it in the equation)
x+3+x=49
2x+3=49
2x=46. X=23
Y=x+3. Y=23+3 =26 for checking 23+26=49
Answer:
50% head and 50% tails.
Step-by-step explanation:
A coin only has two sides to flip on and is equally probably flip heads or tails. If you flipped the coin 20 times you could expect to flip 10 heads and 10 tails.
Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides
