Hello there!
Based from this question above, what this is asking is to find how much does 17% goes into 400 marbles.
We want to know how many marbles are in this 400 marbles. (This would be the key point)
We do (17% x 400).
By putting the "%" symbol this allows us the understand that we are trying to find out how many blue marbles they're going to be.
By multiplying them both together, we got our answer as (68) marbles.
Your correct answer would he 68.
I hope this helps you!
Answer:
Step-by-step explanation:
By the triangle sum theorem, the sum of angles in a triangle is equal to 180°. Therefore, m∠A + m∠B + m∠C = 180°. Using the Substitution property
(6x)° + 90° + (x+6)° = 180°
To solve for x, first combine the terms to get (7x + 96) = 180°
Using the Subtraction property of equality,
7x = 84.
Then using the division property of equality x = 12.
To find the measure of angle A,
Use the subtraction property to get m∠A = 6(12)°.
Finally simplifying the expression gets m∠A = 72°.
Answer:
£63
Step-by-step explanation:
when we subtract 15 from 48 ,we get 63 which is the answer.
