Answer:
Pretend that x and y represents the 2 numbers that we need to find.
According to the information, we know that:
x + y = 21
6x = y
Replace y in the first equation with 6x (because they are equal to each other according to the second equation):
x + y = 21
x + 6x = 21
7x = 21
x = 21/7 = 3
Now have two ways to find y, both will give us the same result:
3 + y = 21 ⇔ y = 21 - 3 = 18
6 · 3 = y ⇔ y = 18
So the numbers that we need to find are 3 and 18.
Answer:
709,007
Step-by-step explanation:
Look at the place values.
In 700, 000, the thousands column is in the third digit. Therefore add nine to that place.
In 700, 000 the ones column is the last digit. So add 7 to that place.
The question is asking to choose among the following choices that states the value of the point e if the ration of ce to cd is 3/8, base on that and on my further calculation, I would say that the value of point e is -1. I hope you are satisfied with my answer and feel free to ask for more
Eight hundred sixty three and 1 hundred 41 thousandths
Solve each system by substitution. Check your solution. Writing How do you know that substitution gives the answer to a system of equations? ... You Would solve the second equationfor y and then substitute back into the first equation.
