subtract 5 from both sides. -1.6r=-5 divide both sides by-1.6. r=-5/-1.6 simp;ify-5/1.6 to 3.125. r =3.125
Answer:
8/21
Step-by-step explanation:
1- 2/7 - 1/3 = 21/21 - 6/21 - 7/21 = 8/21
The solution is D.
By plugging the x value, 5, into the equation:
6*5=30
30+1=31
y=31
the x value is 5 and the y value is 31
(5, 31)
hope that helps!
Answer:
Let the original number be x
Successor is defined as the number which comes immediately after a particular number.
also, the successor of a whole number is the number obtained by adding 1 to that number.
Then, the successor of a number x is, x+1
As per the given condition :
we have;
![5(x+1)+x =83](https://tex.z-dn.net/?f=5%28x%2B1%29%2Bx%20%3D83)
Using distributive property on LHS (i.e,
)
Then, we have
5x+5+x=83
Combine like terms;
6x+5=83
Subtract 5 from both the sides we get;
6x+5-5=83-5
Simplify:
6x=78
Divide both side by 6,
![\frac{6x}{6} =\frac{78}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%20%3D%5Cfrac%7B78%7D%7B6%7D)
Simplify:
x =13
Therefore, the original number x is, 13
