simplify: -2(4 -3y) + 5 (4y - 1)
- 13 + 26y
Answer:
1 is 10x - 8,( 2 is 14n + 15,( 3 is 20y +11,( 4 is -5x - 17,( 5 26y - 13
Step-by-step explanation:
1 you use distributive property so 2 * 5x and 2 * 4, 2 you use distributive property again and add 10n and 4n, 3 you use distributive property and since you multiplying with 2 negatives it makes them positive, 4 you use distributive property and subtracting -15 by two becomes -17, 5 you use distributive property on both and add the rest together.

a 5'10 man weighs 175 pounds. a 6'2 man weighs 200 pounds. do theses men have an equivalent height to weight ratio. Explain ur answer
Answers
Answer: No.
Step-by-step explanation:
5' 10 in inches is 70 inches, 6' 2 in inches is 74 inches
Therefore, the ratio of the first man is 70/175
Dividing by 35 on top and bottom we get 2/5
The ratio of the second man is 74/200
Dividing by 2 on the top and bottom we get 37/100
Since 37/100 does not equal 2/5, these men do not have an equivalent height to weight ratio.

Answer:
For one of them, it will be B=(4.5, 1.5). The sides would each be 3.54 long.
For the second, B=(1.5,5.5). Lines AB and CB are also going to be 3.54 long.
Step-by-step explanation:
My thought process was all over the place, to be honest with you. I drew out the points on some graph paper and found out the length of AC, which is 5. Then I thought I could use the law of sines since we know that the other two angles are both 45 degrees. Anyways, I got the lengths as 3.5. I was a bit off, but I found that out later. I thought of using a compass to try to see where a point would meet if there is a distance of 3.5, but I don't have a compass, so I went searching for online ones. I couldn't find one with a graph in it, so I used an online graphing system. From the beginning, I knew that it was probably going to be something .5, so I kept on trying to find a spot that had a length of 3.5 on both sides, and got really close, but they were still off. I checked where B was graphed, and it was a really long decimal, so I just put it to .5 on both the y and x and voila, I got 3.54 on both lines AB and CB. I, of course, checked my answers and found that the angle was in fact 90 degrees and I felt very pleased with myself. I did a simpler version for the other angle.
I hope this is correct! Please let me know, this was really fun anyways!

What was the percent increase from Day 2 to Day 3?
Enter your answer in the box.
Answers
Answer:
75% or 25%
Step-by-step explanation:
because if you times 0.25 (which is 25%) to 3 it is 0.75 which is 75% so it will increase by 25%.
i don't know honestly, if this is right if it is either 75% or 25%
2 cars started to move from C and from D, towards one another. The car that starts at point C moves twice as fast as the car that starts at point D. How far from boston will those two cars meet?
Answers
Answer:They meet at 92 miles from C or 46 miles from D.
Step-by-step explanation:An object is said to have constant speed if it travels the same distance at the same time. The ratio between the distance x and the time t is the speed and is given by
Solving for x
The car starting from C has double speed as the car starting from D. this means
When both cars meet, they travel these distances
The sum of both distances is x = 256 - 118 = 138 miles.
Or, equivalently
Using the relations of the speeds:
Solving for t
The distance traveled by the car from c is
The distance traveled by the car from d is
There is no reference of where Boston is located, thus we can only refer the distances respect to C or D, as shown above

a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm
8.125/2 = 4.0625 x 192 = 780 cm
5/2 = 2.5 x 192 = 480 cm
Actual dimensions: 780 cm by 480 cm
Divide by 100 to convert to meters:
780/100 = 7.8 meters
480/100 = 4.8 meters
b: area of a triangle = 1/2 x base x height
area = 1/2 x 480 x 780 = 187,200 square cm
1/2 x 7.8 x 4.8 = 18.72 square meters
