Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
For this case we have the following equation:

From here, we must clear the value of x.
Adding By on both sides:

Then, dividing both sides by A we have:

Answer:

x equals the quantity B times and plus C all over A

Answer:
30÷5=6.
Step-by-step explanation:
Quotient means to divide, 30÷5 is 6 since 5x6 or 6x5 is 30.
Answer:
<h2>
43°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is 180°, so the measure of the ohter acute angle:
180° - 90° - 47° = 43°
