Answer: Weight of the remaining block of wood =400g
Step-by-step explanation:
Total Weight of five(5) blocks = 3kg = 3000g
Weight of 4 out of the 5 blocks = 650x 4= 2600g
Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks
= 3000g-2600g
=400g
The sum of 38 and twice a number x is 124. The value of "x" is 43
- 2x - 5 is equal to – 91.
<u>Solution:</u>
Given that , The sum of 38 and twice a number x is 124.
We have to find what is - 2x - 5?
Now, according to given information, 38 + 2 × x = 124
2x + 38 = 124
2x = 124 – 38
2x = 86
x = 43
So, the value of x is 43
<em><u>Now, Evaluating - 2x – 5 </u></em>
Substitute "x" = 43 to evaluate
- 2(43) – 5
- 86 – 5 = - 91
Hence, the required answer is – 91.
