Answer:
I am pretty sure it is A
Step-by-step explanation:
Answer:
5(2x + 6) = -4(-5 -2x) + 3x
10x + 30 = 20 + 8x + 3x
10x + 30 = 20 + 11x
Applying the additive inverse property, we get,
10x + 30 - 10x - 20 = 20 + 11x - 10x - 20
10 = x
Answer:
18.
∠2 = 40
∠3 = 140
∠4 =140
19.
∠1 = 134
∠2 = 46
∠3 = 134
∠4 = 46
Step-by-step explanation:
18. Using vertical angle theorem, 1 is equal to 2 and 3 is equal to 4. Therefore 2 is equal to 40 degrees. Then since 2 and 3 are supplementary adjacent angles or a linear pair, they equal 180 when combined. 180-40 equals 140. 3 and 4 are also vertical angles so 3 = 4 and they are both 140.
19. Angles 1 & 3 and 2 & 4 are vertical angles because they are directly across from each other and share the same bisectors. You can use what you know about special angle pairs to find the measure of each angle because since 1 & 3 are vertical angles and 2 & 4 are also vertical angles, 1 is equal to 3 and 2 is equal to 4. So, since the angle formed at the right is angle 2, we can confirm that angle 4 is equal to it and therefore angles 2 and 4 are 46 degrees. Then since angles 1 & 2 and 3 & 4 are linear pairs, we can say that angle 1 + angle 2 is equal to 180 and the same for angles 3 & 4. So subtract 180 - 46 and you get 134. Therefore angles 1 and 3 are equal to 134 degrees.
<span>Let x be the number. By the given above, the relationship between the numbers and the newly-introduced variable is expressed as (2/5)(x) = 14. To determine the value of x, divide 14 by 2/5. This will give us the answer which is equal to 35. Hence, the answer to this item is 35. </span>
The amount of necklaces she can make is 56
To work this out, you would divide 1799 by 32, to get 56 necklaces with 7 beads left over.
Hope this helps!
