U+6y=32 U+3y=17
Solve U+6y=32 for u
Add -6y to both sides
U+6y-6y=32-6y U= -6y+32
Substitute -6y+32 for U in U+3y=17 U+3y=17 -6y+32+3y=17
Simplify both sides of the equation -3y+32=17
Add -32 to both sides -3y+32-32=17-32 -3y=-15
Divide both sides by -3 -3y/-3 = -15/-3 Y=5
Substitute 5 for y in U=-6y+32 U= -6y+32
U= (-6)(5)+32 u= -30 +32 U= 2
Answer : U= 2 and Y=5
I hope that's help and have a great night !
The required number is 238.88 and 18% of it would be 43.
The percentage is defined as a ratio expressed as a fraction of 100.
The % formula is used to calculate a percentage of a whole in terms of 100. Calculating percentages indicated above can be readily computed using the formula below:
Percentage = (Value/Total Value) × 100
Let's the unknown number would be x.
According to the given question, we have to determine the evaluation of 18% of x = 43.
⇒ 18% of x = 43
18% is expressed as 18/100 in fractional form
⇒ (18/100)x = 43
18/100 is expressed as 0.18 in decimal form
⇒ (0.18)x = 43
⇒ x = 43/(0.18)
Apply the division operation, and we get
⇒ 238.88
Therefore, 18% of 238.88 would be 43.
