<u>Answer:
</u>
One number is 10 more than twice another.Their sum is 1.The numbers are -3 and 4
<u>Solution:
</u>
Given that one number is 10 more than twice the other.
Let us consider the two numbers as “x” and “y”
First number = x
Second number = y
From question, consider “y” is 10 more than twice the “x”. This can be represented
y = 10 + 2x – eqn 1
given that the sum of numbers is 1. Hence we get
x + y =1
substituting the value of “y” we get
x + 10 +2x = 1
3x +10 = 1
3x = -9
x = -3
substitute x = -3 in eqn 1 to get the value of “y”
y = 10 +2(-3)
y=10 – 6 = 4
hence the two numbers are -3 and 4

Answer:
2 candies to each friend
Step-by-step explanation:
This is a division problem. You would do:
10/5 as there are 10 candies to share and 5 friends to give them to. This would yield a result of 2 candies per friend.
Answer:
The radius is 9.9 units
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
In the right triangle of the figure ABC
Applying the Pythagorean Theorem
substitute the given values
solve for AB
Remember the the side AB of right triangle represent the radius of the circle
therefore
The radius is 9.9 units
Answer: y =21; x = 7√3
have: cos 60° = x/(14√3) = 1/2 => x = 1/2. (14√3) = 7√3
sin 60° = y/(14√3) = (√3)/2 => y = (√3)/2 . 14√3 = 21
Step-by-step explanation:
