Answer:
If 2/5 are apples, 2/5 x 8.9 kilos = 0.4 x 8.9 = 3.56 kilos of apples
pears = 8.9 - 3.56 = 5.34 kilos
if apples are 2/5, then pears are 3/5. 3/5 x 8.9 = .6 x 8.9 = 5.34 kilos of pears
Answer:
x = 8
Step-by-step explanation:
We can use PEMDAS to solve algebraic equations:
Parentheses
Exponents
Multiplication/Division
Addition/Subtraction
First, we have parentheses in this equation, so distribute
3(11x) + 3(5) = 279
Next, because there are no exponents, multiply
33x + 15 = 279
To isolate x, subtract 15 from both sides
33x + 15 - 15 = 279 - 15
33x = 264
Then divide both sides by 33
x = 8
