Answer:
Step-by-step explanation:
We need a system of equations here. The first equation is that 3L boxes + 5s boxes (L = large and s = small) = 88 kg so
3L + 5s = 88
12L + 2s = 235 according to the other information given.
Solve the first equation for either L or s. I'll solve for L, just because:
3L = 88 - 5s and
L =
and sub that into the second equation for L:
and if you distribute the 12 into the parenthesis you'll simplify it down a bit to
352 - 20s + 2s = 235 and combine like terms:
-18s= -117 so
s = 6.5 kg and plug that in to solve for L:
L =
and
L = 18.5 kg
There are two chances of getting one tails: if the first toss is heads and the second toss is tails OR if the first toss is tails.
The probability of the first toss to be head AND the second toss to be tails is 1/2 × 1/2, which equals 1/4.
The probability of getting a tails on the first toss is 1/2.
When dealing with probabilities, AND means multiply and OR means add. Therefore, this problem is: (heads AND tails) OR (tails). The probability of a coin landing on heads is 1/2 and the probability of a coin landing on tails is 1/2. Therefore, the equation is (1/2 × 1/2) + (1/2), which is 3/4.
One equation that represents this statement above me could be: <span>4r + 3 (10-r) = 37.
</span>How? R = Rollercoaster - B = Boat Rides
r + b = 10
37 tickets were spent so..
4*r + 3*b = 37
We just multiplied the number of rides on roller coasters and the boats with the price of both.
Now we have to express boat rides from the first equation:
b = 10-r, and express that in the second equation, now we get:
4r + 3(10-r) = 37, which is the answer.
No it is not. It increases by 1 more each time.
So it is an increase of 5, then an increase of 6, then an increase of 7. This means it is not arithmetic.
Answer:
x < −4
Step-by-step explanation:
Add 6 to both sides.
-5x> 14 + 6
Simplify 14+6 to 20.
-5x>20
Divide both sides by -5.
x<-20/5
Simplify
x<−4
