Answer:
x = 111
Step-by-step explanation:
1.) x + (x + 1) + (x + 2) = 336
2.) x + x + 1 + x + 2 = 336
3.) 3x + 3 = 336
4.) 3x = 333
4.) x = 111
Check Work:
1.) 111 + (111 + 1) + (111 +2) = 336
2.) 111 + 111 + 1 + 111 + 2 = 336
3. ) 222 + 1 + 111 + 2 = 336
4.) 222 + 114 = 336
5.) 336 = 336
Answer:
(2 × 16) - 1
Step-by-step explanation:
31 = 2n - 1
31 + 1 = 2n
32 = 2n
16 = n
therfore, 31 can be written as :-
<h3>31 = (2 × 16) - 1</h3>
Short answer 8x1
Because 2x4=8
And 8x1=8
So they are equivalent
Answer:
a =5
Step-by-step explanation:
-26a-3+20a=27
Combine like terms
-6a -3 = 27
Add 3 to each side
-6a -3+3 =27+3
-6a = 30
Divide each side by -6
-6a/-6 = 30/-6
a =5
X = 1.5 times (150-x)
x = 225 -1.5x
2.5 x = 225
x= 90
The more expensive book was $90
Check your answer:
x = 1.5 times (150-x)
90 = 1.5 times (150-90)
90 = 1.5 x60
90=90
