Answer:
1= 5x and 7x
2= 3x and 2x
Step-by-step explanation:
its hard to explain you just add them or minus them
Answer:
The probability of not rolling a 4 on the die and flipping heads on the coin is 5/6.
Step-by-step explanation:
Assuming the die is 6-sided, the probability of not rolling a 4 is 5/6, because all other possible values other than 4 can be rolled to make the probability true. 5/6
The probability of flipping heads on the coin is 1/2, considering there are 2 sides on the coin, heads, and tails.
To find the probability of both these events occurring, multiply both the probabilities together. (5/6) * (1/2) = 5/12.
Answer:
see below
Step-by-step explanation:
Since 2x appears on the left side of both equations, that term can be eliminated by subtraction, which is what the first choice suggests.
The result will be ...
3y = 7 -4y +5 . . . . . . . . . second equation subtracted from the first
7y = 12 . . . . . . add 4y
y = 12/7 . . . . . . divide by 7
__
However, the fact that 2x is by itself on the left side of the second equation suggest that <em>substitution</em> may also be a good option. Perhaps an equally good first step is to use the expression in the second equation to substitute for 2x in the first:
(4y -5) +3y = 7
Either way, the resulting equation is 2-step.
7y = 12 . . . add 5
y = 12/7 . . . divide by 7
___
The other suggested "first steps" do nothing useful.
The answer would be 15. You subsitute 26 for m. So it would be 26 - 11 = 15
