X+x+2= 156
<span>2x+2=156 </span>
<span>2x= 154 </span>
<span>x= 77 </span>
<span>1st number = 77 </span>
<span>2nd number = 79</span>
Step-by-step explanation:
6+6=12
As, 6 x 2 = 12
An example = 6 books were in ur classmates desk, and u had 6 book as well in ur desk
U wanted to build a tower of books
So merged them together
And put them on each other until all books are done
Which now u will simply add the 6 books of ur classmate and urs
Which will be 12 book
Factor 36 and add them, make sure both are negatie
1+36=37, nope
2+18=20 nope
3+12=15,nope
4+9=13, nope
6+6=12, nope
the closest one is 20
I hope you meant adds to -20, because if you did, then answer is -2 and -18
if you did mean 36 and adds to -21, then the numbers are
and
, aprox -19.1168 and -1.8831
K = Kevin's age
D = Daniel's age
K = 3D
K - 4 = 5(D - 4)
Plug in 3D for the K values in the second equation.
3D - 4 = 5(D - 4) Use the Distributive Property
3D - 4 = 5D - 20 Add 4 to both sides
3D = 5D - 16 Subtract 5D from both sides
-2D = -16 Divide both sides by -2
D = 8
Now, plug that D value into the original equation.
K = 3D Plug in the D value
K = 3(8) Multiply
K = 24
Finally, you can double check your math.
4 years ago, Daniel would've been 4 and Kevin would be 20, so Kevin would've been 5 times as old as Daniel. And 8 x 3 = 24.
So, Kevin is 24.
