Answer:
The area left to build is 
Step-by-step explanation:
The question in English is
The area of a property in square meters, measures 704/5. A house is built that occupies 5/6 of the total area. Half of the remaining area is used to build a terrace, how much area is left to build?
we know that
The total area represent the fraction 6/6
A house represent the fraction 5/6 of the total area
The remaining area represent the fraction (6/6)-(5/6)=1/6 of the total area
If half of the remaining area is used to build a terrace
then
the area of the terrace represent the fraction (1/6)/2=1/12 of the total area
therefore
The area left to build represent the fraction 1/12 of the total area
so
Answer:
-31
Step-by-step explanation:
First let's plug in the value of z into the expression as it looks easier than expanding,
6(-1) + 5(-2(-1)-7)
Now we follow the order of PEMDAS,
6(-1) + 5(2-7)
6(-1) + 5(-5)
-6 - 25
-31
Answer:
Step-by-step explanation:
Let x equal the first mile marker. Then x + 1 represents the second mile marker.
Then x + (x + 1) = 561, or
2x + 1 = 561, or
2x = 560, and so x = 280
Then the first mile marker reads 280 and the second mile marker reads 281.
Answer:
<u>The sum of their ages now is 13</u>
Step-by-step explanation:
Dally's age = x
Dilly's age = x - 7
In 4 years time Dilly will be half Dally’s age, therefore:
Dilly's age plus four equals to half of Dally’s age plus four,
replacing with the values and variables we know:
x - 7 + 4 = (x + 4) /2
x - 3 = (x + 4) /2
2x - 6 = x + 4 (Multiplying by 2 at both sides)
2x - x = 4 + 6 (Like terms)
x = 10 ⇒ x - 7 = 3
<u>The sum of their ages now is 13 (10 + 3)</u>
Answer:
-42
Step-by-step explanation:
negative * negative = positive
positive * negative = negative
negative * positive = negative
(-6)(-7)(-1) =
= 42(-1)
= -42
