Answer:
Step-by-step explanation:
r=p(1+20/100)
r=p(120/100)
r=1.2p
6(x + 2) = 2(x + 10)
6x + 12 = 2x + 20
6x - 2x = -12 + 20
4x = 8
x = 8/4
x = 2
3(y - 4) + 2 = 5y - 28
3y - 12 + 2 = 5y - 28
3y -10 = 5y - 28
3y - 5y = 10 - 28
-2y = -18
y = -18/-2
y = 9
5(2z - 3) - 3z = 3(z + 3)
10z - 15 - 3z = 3z + 9
7z - 15 = 3z + 9
7z - 3z = 15 + 9
4z = 24
z = 24/4
z = 6
To determine the rate that an individual walks. Take each set values and put in the following formula to solve for the rate.
Rate = number of feet/ seconds
Person 1 = 60 feet / 10 seconds = 6 feet/sec
Person 2 = 25 feet / 5 seconds = 5 feet/second
Person 1 walks at a faster rate than person 2.
Answer:
70%
Step-by-step explanation:
there are 20 total marbles and only 14 are not blue so 14/20 = 7/10 = 70%
The next number is 31
There is a pattern
3+1=4
4+2=6
6+3=9
9+4=13
13+5=18
18+6=24
24+7=31
You just add the total you got by the next number up.
Hope this helps
