Answer:
the selling price of the goods is ₹6,00,000
Step-by-step explanation:
The computation of the selling price of the goods are shown below:
As we know that
Selling price = Cost price + profit
= 5,00,000 + 5,00,000 × 0.20
= 5,00,000 + 1,00,000
= ₹6,00,000
Hence, the selling price of the goods is ₹6,00,000
Answer:
1200 students at the school
Step-by-step explanation:
Let x be the total number of students at the school
50% ride the bus
600 students ride the bus
x*50% = 600
Changing to decimal form
.50x = 600
Divide each side by .5
.50x/.5 = 600/.5
x =1200
1200 students at the school
Dude I don’t think using this for an exam is it but ok
Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
