The marked angles are opposite angles, and as such they have the same measure. So, we have
Subtract 2a and 11 from both sides to get
Divide both sides by 4 to get
Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:
30 bags of flour + 4 bags of sugar = 42.6 kg
each bag of sugar weighs 0.75 kg
each bag of flour weighs x kg = ?
If you would like to know what is the weight of each bag of flour, you can calculate this using the following steps:
30 * x + 4 * 0.75 kg = 42.6 kg
30 * x + 3 kg = 42.6 kg
30 * x = 42.6 kg - 3 kg
30 * x = 39.6 kg /30
x = 39.6 kg / 30
x = 1.32 kg
Result: Each bag of flour weighs 1.32 kg.
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches
It is 1/5 because it is 1 difference on the top and a 5 difference on the bottom number
