Answer:
youngest 17
middle 19
oldest 21
Step-by-step explanation:
Three sisters have ages that are consecutive odd integers
youngest = x
middle = x + 2
oldest = x + 4
--------------------
The sum of the age of the youngest
x
and three times the age of the oldest
+ 3(x + 4)
is five less than five times the middle sister’s age
= 5(x + 2) - 5
-----------------------
x + 3(x + 4) = 5(x + 2) - 5
Distribute
x + 3x + 12 = 5x + 10 - 5
Combine like terms
4x + 12 = 5x - 5
Subtract 4x from both sides
12 = x - 5
Add 5 to both sides
17 = x
youngest x = 17
middle x + 2 = 19
oldest x + 4 = 21
17x(1-2y)
17x-34xy
because both expressions have a x, it would be easier to factor out the x first. but because 17 is a factor of 34 you can simply divide 34 by 17 and get 2. so you put it together to this,
17x(1-2y)
Because, 17x times 1 is 17x but 17x times -2y would be -32xy.
Answer:
y=-2x+4
Step-by-step explanation:
y=mx+b
y=-2x+b
4=-2(0)+b
4=0+b
4=b
y=-2x+4
First, you need to find the unit rate. To find the unit rate, divide 105 by 3. (105<span>÷3=X) Then, take the variable X and multiply it by 11, because X tells us how far the Antelope can go in 1 hour. X x 11 = Y. To get the problem right, write, "The Antelope can travel Y (but put the number Y is equal to) </span> miles per hour (or mph)
