Answer:
P = 4x + 10
Step-by-step explanation:
perimeter of a rectangle = 2( width + length )
P = 2 ( x - 2 + x + 7 )
P = 2 ( x + x + 7 - 2 )
P = 2 ( 2x + 5 )
P = 4x + 10
3x+5y=11 answer : 3x+5y-11=0
Step by step explanation:
3x+5y=11
Move the constant to the left
3x+5y-11=11-11
Eliminate the opposite
3x+5y=11
5y+8y
So.... there are 10 crayons and 8 are yellow.
This means that 8/10 of the crayons are yellow.
So the chance of picking a yellow one is 80%.
To get this, you need to do 8/10 and make it over 100, which is 80/100. Then, you turn this number into a percent by just dropping the 100 and adding a % to 80 (it's this easy if the bottom denominator is 100)
The work should look something like this;
8:10
8/10
80/100
80%
So, there is an 80% chance that the crayon you pick will be yellow. Any questions?
