Answer:
4g - 1
Step-by-step explanation:
4 and -5 are numbers
While, -6g and 10g are variables.
Add numbers and variable separately.
4 + -6g + 10g + -5
= 4 - 5 + 10g - 6g
= - 1 + 4g
= 4g - 1
Answer:

Step-by-step explanation:
We need to use the formula to calculate the probability of (A or B) where
A=Probability a student likes pepperoni
B=Probability a student likes olive
A and B =Probability a student likes both toppings in a pizza
A or B =Probability a student likes pepperoni or olive (and maybe both), a non-exclusive or
The formula is

Since 6 students like pepperoni out of 9:

Since 4 students like olive out of 9:

Since 3 students like both toppings out of 9

Then we have


Answer:

Step-by-step explanation:
Using the rule of exponents
×
⇔
, thus
4² ×
=
= 
First you subtract 9 from both sides, so you get -2x=26
Then you divide both sides by -2 which is x=-13
So your answer is -13.
Answer:
a < 42
Step-by-step explanation:
Question : 4a + 9a - 6a < 42
Answer :
4a + 9a - 6a < 42
Combine like terms.
13a - 6a < 42
7a < 42
Divide both sides by 7.
a < 42
