Answer is YES
Because
2 ones = 2 x 1 = 2 and 20 tenths = 20 x 0.1 = 2
So if you let x and y be the two numbers...
the sum of the two means you add them together... so you get:
x+y=56 : the difference means you subtract them.. so
x-y = 16
now you have two equations and two unknowns... which you can solve with a variety of methods... you can use elimination, substitution, or trial and error.
x+y=56
x-y = 16
I will use the elimination method: Because there is a plus y and a negative you cancel that out and you add the 2x's. Therefore:
2x=72
x=36
Now, you can plug in 36 into one of your original equation:
36+y=56
y=20
Those are your two numbers!
Divide the amount of money earned by the amount she got from every house.
780 / 5 = 156
156 out of 278 houses payed money. Subtract to see how many did not pay money
278 - 156 = 122
Hannah did not collect money from 122 of the houses in her neighborhood.
Answer:
8x = 32
8/8x = 32/8
x = 4
Step-by-step explanation:
Right now we have:
5kx + 6 = 7kx
First, divide both sides by k to eliminate that variable:
5x + 6 = 7x
Then subtract 5x from each side:
6 = 2x
Lastly, divide each side by 2 to solve for x:
3 = x
Hope this helps!
