Answer:
Combining like terms is actually pretty straightforward, you just have to combine like terms. In the problem 5c+2c, it would equal 7c since c is a common variable in this equation.
In the next question 16p+5+p-3x+6-x, it would equal 17p-4x+11 because 16p+p is 17p, -3x-x is -4x, and 5+6 equals to 11.
In the third question 18p+3-8p-5 would equal to 10p-2 since 18p-8p equals to 10p, and 3-5 equals to -2.
In the last question 9u+11v-22u+12v, it would equal to -13u+23v because 9u-22u equals to -13, and 11v+12v is 23v.
I hope this helped you!
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
Answer: A 4 side dice.
Step-by-step explanation:
Benjamin has 4 possible homerooms with the same probability. This means that every homeroom has a 1/4 = 0.25 (or 25%) probability of getting chosen.
You could emulate this situation with a 4 sided dice (are like little pyramids) where each side of the dice would represent the selection of one of the homerooms.
The answer is 2/9. the other three are terminating decimals. just use a calculator to divide 2 by 10. and 22 by 100 and so on. you’ll see that 2 divided by 9 is .2222222
