Answer:
500 and 900
Step-by-step explanation:
3(x - 300) + 2(x + 100) = 3300 ← distribute parenthesis
3x - 900 + 2x + 200 = 3300
5x - 700 = 3300 ( add 700 to both sides )
5x = 4000 ( divide both sides by 5 )
x = 800
Then
cost of book = x - 300 = 800 - 300 = 500
cost of pen = x + 100 = 800 + 100 = 900

Step-by-step explanation:
here you go mate
step 1
-2(-4x-1)-x+3=−30 equation/Question
step 2
-2(-4x-1)-x+3=−30 distribute
7x+5=-30
step 3
7x+5=-30 subtract 5
7x=-35
step 4
divide
answer
x=-5
Answer: just follow these simple steps!
Step-by-step explanation:
1. Estimate the quotient.
2. Perform the division. Remember to place a zero in the quotient when the divisor is larger than the dividend. ...
3. Compare your estimate with your quotient to verify that the answer makes sense.
Basically plug in 2 where y is and 5 where X is
3(5)(2) - 4(2) , the parentheses are there to multiply
30-8
22
If the diameter is given in a problem, area is computed as
A = (π/4) × D<span>2 where </span><span>π is equal to 3.14</span>
<span>If D (diameter) of one circular table is 6 ft its Area is 28 sq ft.</span>
If D of another circular is 8 ft its Area is 50 sq ft.
<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>
