<span>Let the cost of 2-scoop cones be x, and the cost of sundaes be y.
The first statement tells us that 5x = 3y
The second statement tells us that 9x + 6y = 19.95
Then we need to calculate the value of y (the cost of a sundae).
From our first equation, y = 5x/3. Substituting this into the second equation:
9x + 6(5x/3) = 19.95
9x + 10x = 19.95
19x = 19.95
x = 1.05
Substituting back into the first equation: 5(1.05) = 3y
5.25 = 3y
y = 1.75
Therefore the cost of a sundae is $1.75.

Answer:
D
Step-by-step explanation:
x³ = 64/27
Take the cube root of both sides.
x = ∛(64/27)
Distribute the cube root to the numerator and denominator.
x = (∛64)/(∛27)
Take the cube root of the terms.
x = 4/3
Then he slept 9 times. Because every hour is 60 minutes, since 1/3 of an hour is 20 mins, it should be 3 times per hour. So using basic math, 3 times 3 equals 9
Answer:
12/25
Step-by-step explanation:
If you got 26 tails, that means you got 50 - 26 or 24 heads. The experimental probability can be represented by the desirable flips over the total number of flips. We are looking for heads, so the amount of heads is the amount of desirable flips, and the total is 50. From this, we get the fraction 24/50 which simplifies to 12/25.
You are subtracting -16-4
So I would assume your answer would be C
I hope this answer helps!
