Answer:
7 and 9
Step-by-step explanation:
Variables:
x = smaller number
y = larger number
We can set up two equations with the information given:
5x + 3y = 62
and
y = x + 2
We get the second equation with the information that the two numbers are consecutive and both odd. therefore the smaller number is two less than the larger number, and the larger number is two greater than the smaller number.
Next, we need to replace our y in the first equation with the y in the second:
5x + 3y = 62
5x + 3 (x+2) = 62
5x + 3x + 6 = 62
8x = 56
x (smaller number) = 7
Finally, we solve for the larger number by placing it back into the second equation:
y = x + 2
y = 7 + 2
y (larger number) = 9
I hope this helps!

Answer:
F=121.61 gr,
Step-by-step explanation:
we see that it is a problem of proportion, so then if the total mass of the sample is the sum of M plus fluorine
the sample weighs 1.38gr M + 0.71gr F = 2.09, where M y F represent :
M=1.38*100/2.09 = 66.02% and
F=0.71*100/2.09 = 33.97%, also
in 358 gr. * 0.3397F = 121.61 gr F
If you divide 8 from 140 you'll get 17.5 or 1120<span />
Answer: The equation would be 59.50 = 30 + .25x. You would solve by subtracting 30 from 59.50, and you get 29.5. Then dividing .25 by that, and you get 118. So you sent 118 texts. i think this is the answer good luck :D
