Answer:
38.8 litres
Step-by-step explanation:
22.6 + 18.7 = 41.3

38.8 litres
Answer:
x = 8
Step-by-step explanation:
since it's a collinerar
or, AB+BC=AC
or, 3x+5x+10 = 74
or, 8x = 74-10
or, 8x = 64
or, x = 64/8
x = 8
The equation -21t - 4 = 10 - 2t has only one solution
<u>Solution:</u>
Given, equation is – 21t – 4 = 10 – 2t
We have to find how many solutions does the above given equation have
Now, let us solve the given equation to find the number of solutions it has.
Then, - 21t – 4 = 10 – 2t
Taking like terms to one side of the equation we get,
- 21t + 2t = 10 + 4
![\begin{array}{l}{-19 t=14} \\\\ {19 t=-14} \\\\ {t=-\frac{14}{19}}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B-19%20t%3D14%7D%20%5C%5C%5C%5C%20%7B19%20t%3D-14%7D%20%5C%5C%5C%5C%20%7Bt%3D-%5Cfrac%7B14%7D%7B19%7D%7D%5Cend%7Barray%7D)
here we can see only one value of t.
Hence, the given equation has only one solution.
