Draw the given answers to determine the correct solution.
ΔABE is correct because it is a right triangle through a diagonal
ΔABD is incorrect because it does not go through diagonals.
ΔADH is incorrect because it does not go through diagonals.
ΔACE is incorrect because it does not go through the interior of the cube.
Answer: ΔABE
Okay. So 90 yds was cut from the 230 yd yarn. 230 - 90 = 140. 1/2 of 140 is 70. 230 - 70 = 160. The yellow yarn was 160 yds longer than the blue yarn at first.
Answer:
99x78=7722
123x56=6888
98x172=16856
900x38=34200

Hi there!
There are two steps to take when solving this equation, but before we even think about that, let's start by rewriting the equation.
5a + 17 = 47
Step 1) Subtract 17 from both sides.
5a + 17 - 17 = 47 - 17
5a = 30
Step 2) Divide both sides by 5.
5a/5 = 30/5
a = 6
So, your final answer therefore is
a = 6
Hope this helps!
TIP - This method can be used when solving any equation with 1 variable. :D
The equation for finding the equation of an arithmetic sequence is an=a1+(n-1)d, where n is the input for the sequence, a1 is the first term, and d is the difference between each term.
a1= 1/4
d= 1/4
an= 1/4 + (n-1)(1/2) - First you need to distribute the 1/2 to both the n and -1 to get: an= 1/4 + 1/2n -1/2.
Then you need to add like terms (1/4-1/2) to get an=1/2n-1/4. Hope this helps!
