R=3*S
in 6 years ⇒R+6=2*(S+6)
3*S+6=2*S+2*6
3S+6=2S+12
3S-2S=12-6
S=6
R=3*6=18 ( Ralph 's age now)
in 6 years Ralph's age will be 3*x+6
Answer:
The answer is C
Step-by-step explanation:
There are 2 X's therefore there will be two sets of quotations with one X in each. Then find the multiples of 50.
Try -5 and +5 go in with the x which makes the answer C
X / 100 = 51.82....multiply by 100 on both sides
x = 51.82 * 100
x = 5182 <== sum of all 100 numbers

Answer:
Step-by-step explanation:
Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."
So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.
w = 112 +8t
176 = 112 + 8t
64 = 8t . . . . . . . subtract 112
8 = t . . . . . . . . . divide by 8
The input for an output of 176 is 8.
__
Ordered pairs are always written as ...
(input, output)
So, (4, 144) means the output is 144 for an input of 4.
