What is the sum of 8 and 7 doubled in a numerical expression
Answers
Answer:
2(8+7)
Step-by-step explanation:
sum is addition so add 8+7 then its doubled so u put parenthesis and double by 2
Final answer:
The sum of 8 and 7, doubled, is calculated by first adding 8 and 7 to get 15. Then, the 15 is doubled resulting to 30.
Therefore, the numerical expression that represents the sum of 8 and 7 doubled is 30.
Explanation:
The question asks for the sum of 8 and 7, doubled. We first do the operation within parenthesis, then double (multiply by 2) the result. Here's the step-by-step process:
- Add 8 and 7 to get 15.
- Double the result of 15 by multiplying it by 2. So, 15 x 2 equals 30.
Therefore, the numerical expression that represents the sum of 8 and 7 doubled is 30.

Answer: x=6/k
Step-by-step explanation:
kx + 12 = 3kx and subtract k from both sides
12=3kx-kx then simplify
12=2kx, now divide both sides by two
12/2=kx simplify again
6=kx divide next
6/k=x finally, switch sides to get x=6/k

Remember:complimentary angles add up to 90 while supplementary angles add up to 180.
Final answer:
The two angles are 13 degrees and 77 degrees respectively. Since they are complementary, they add together to make a total of 90 degrees.
Explanation:
In this question, we are seeking the measure of two angles. These angles are complementary, meaning together they add up to 90 degrees. Let's denote the first angle as 'x' and the second angle (which is 64 degrees more than the first) as 'x+64'.
Since they are complementary, this indicates that:
x + (x + 64) = 90
This simplifies into:
2x + 64 = 90
We can then subtract 64 from both sides, giving:
2x = 90 - 64, so 2x = 26
Therefore, if we divide both sides by 2 to isolate 'x', we get:
x = 13
So, the first angle measures 13 degrees. The second angle, as specified in the question, is 64 more than the first angle, so it measures:
x + 64 = 13 + 64 = 77 degrees
Result:
The first angle measures 13 degrees and the second angle measures 77 degrees.
