Question

please answer the question it is very important for me​

Answer 1

Answer:

v) 2x + 3% of 5x = 86 is 2

vi) 5t-6% of 10t= 176/5 is $\frac{880}{111}$

Step-by-step explanation:

v) 2x + 3% of 5x = 86

to convert % into fraction, divide the given number by 100

2x + (3/100) 5x = 86

2x + 15x/100 = 86

2x + 3x/20 = 86

multiplying and dividing 2x by 20,

$\frac{2x X 20}{20} + \frac{3x}{20} = 86$

$\frac{40x}{20} + \frac{3x}{20} = 86$

$\frac{40x + 3x}{20} = 86$

$\frac{43x}{20} = 86$

multiplying by 20 on both sides,

$\frac{43x X20}{20} = 86X20$

860x = 1720

dividing by 860 on both sides,

860x/860 = 1720/860

x=2

vi) 5t-6% of 10t = 176/5

5t - (6/100)t = 176/5

5t- 6t/100 = 176/5

5t- (3t/50) = 176/5

multiplying and dividing 5t by 50,

$\frac{5tX50}{50} - \frac{3t}{50}= \frac{176}{5}$

$\frac{225t}{50}-\frac{3t}{50}=\frac{176}{5}$

$\frac{225t-3t}{50}= \frac{176}{5}$

$\frac{222t}{50}=\frac{176}{5}$

multiplying and dividing RHS by 10,

$\frac{222t}{50}=\frac{1760}{50}$

multiplying both sides by 50,

222t = 1760

$t=\frac{1760}{222}$

$t=\frac{880}{111}$
