Answers:
- DH is <u>correct</u> because a line is connecting the two points D and H as shown in the image, forming a <u>line segment</u>.
- ED is <u>correct</u> because a line is connecting the two points D and E, forming another <u>line segment</u>, as shown in the drawing.
- EH is <u>incorrect</u> because in the drawing shown, there is no line connecting the two points E and H, so there would be <u>no line segment</u> formed between these two points.
- CD is <u>correct</u> because there is another line connecting the two points C and D, forming another <u>line segment</u> in the drawing.
<u>Therefore, lines DH, ED, and CD are all line segments.</u>
Answer:
Step-by-step explanation:
You can either substitute (8, 3) into both equations as a test, or you can find the solution yourself.
Rewrite
- x + 4y = 4
- x + 3y = 1
as
- x + 4y = 4
+ x - 3y = -1
and combine like terms. The result is y = 3. Then -x + 4(3) = 4, or 8 = x.
Yes, (8, 3) is a solution of this SYSTEM.
Given a number of tablespoons, find the number of cups:
Since he needs 2 cups, he can use 2×16=32 tablespoons.
Since he needs 12 cup, he can use 12×16=8 tablespoons.
He needs 114 cups. 1 cup is 16 tablespoons. 14 cup is 14×16=4 tablespoons. So altogether he needs 16+4=20 tablespoons.
Given a number of cups, find the number of tablespoons:
20 tablespoons is 114 cups. So for 28 tablespoons an additional 8 tablespoons, or an additional 12 cup. 114+12=134, so 28 tablespoons gets him 134 cups. (Alternatively, we might say that 1 tablespoon is 116 cups. 116×28=2816, which we can rewrite as 11216 or 134.)
Notice that to convert from tablespoons to cups, Divide by 16. 6÷16=616, which we can write as 138. (Alternatively, 1 tablespoon is 116 cups. 116×6=616, which we can rewrite as 138.)
Here is your answer:
1 1/2 = 3/2
7 × 3 = 21
8 × 2 = 16

<--- Real answer:
The reason why she multiplied her answer wrong, she also "kept her original numerator and denominator."
Hope this helps!
