5 ten is equal to 50.
So, then what is 50 + 50
100
There's no need to get into an ethical morass over math homework.

M is 20% less than N means
M is 100-20=80% of N
M=0.80 N
M/N = 0.8 = 4/5
Ratio: 4/5

When we know <em>a, </em>the average, and <em>n, </em>how many numbers there are, we know the sum <em>s</em>, because <em>a=s/n </em>so <em>s=na.</em>
So the sum of our six numbers is 6(3.5)=21 so the sum of the seven numbers is 21+4.2=25.2 so the average is 25.2/7 = 3.6
Answer: 3.6

|2p + 4 | < 3
At p=-2 the absolute value is zero. As p gets more negative the absolute value argument (inside part) gets negative and the absolute value gets bigger, more positive. Eventually the inside will be exactly -3, when
2p +4 = -3
2p = -7
p = -7/2 = -3 1/2
So p=-4 will make the inequality false, and p=-3 is the smallest integer that makes the inequality true.
Answer: -3

The distance from the origin is given by the Pythagorean Theorem and this one is a 3/4/5 right triangle:

Answer: .5 or 1/2
Hi,
You can write your problem as:
x = 8 + 3y
x + y = 28
So
(8 + 3y) + y = 28
4y = 28 - 8
4y = 20
y = 20/4 = 5
x + y = 28
x + 5 = 28
x = 28 - 5 = 23
The numbers are 23 and 5.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
Answer:
Step-by-step explanation:
lateral area=πr²h=π×3²×6=54π sq. yards
surface area=2πr²+πr²h=2π×3²+54π=18π+54π=72π sq. yards
20% of 50 is 10
Half of 50 is 25
25 + 10 = 35
50 -35 = 15
15 of the backpacks were neither pink or blue
Hope this helps :)
