Answer:
5
Step-by-step explanation:
-x + 3y= 18
X= 3
-(-3)+3y =18
3 + 3y= 18
Subtract 3 from both sides.
3y = 15
Divide by 3 on both sides.
Y= 5
Answer:
Step-by-step explanation:
0.2³ + (1/5 × 3/4) - 1/12
According to my syllabus, we use BODMAS. i.e <em>Brackets, Of, Division, Multiplication, Addition </em>and <em>Subtraction</em> in that order.
0.2³ + 3/20 - 1/12
0.008 + 3/20 - 1/ 12
Change the decimal to a fraction and work out the rest.
Answer:
D is your answer
Step-by-step explanation:
The missing reason is (d) Add the fractions together on the right side of the equation
<h3>How to complete the missing reason?</h3>
From the statements, we have the following equation:
x^2 + b/a x + (b/2a)^2 = -4ac/4a^2 + b^2/4a^2
Next, we add the fractions on the right-hand side of the equation.
This gives
x^2 + b/a x + (b/2a)^2 = [-4ac + b^2]/4a^2
The above means that the last statement is gotten by adding the fractions on the right-hand side of the equation.
Hence, the missing reason is (d) Add the fractions together on the right side of the equation
