The solution is D.
By plugging the x value, 5, into the equation:
6*5=30
30+1=31
y=31
the x value is 5 and the y value is 31
(5, 31)
hope that helps!
The answer is 15x + 15
Each person needs to pay x dollars per hour, and also 3 dollars for a helmet
Let us convert this into a pseudo-expression:
1 person = (x dollars) x (y hours) + 3 dollars
Now, it says that there are 5 people, so we need to multiply both sides by 5
5 people = 5 x (x dollars) x (yhours) + 3 x 5 dollars
Furthermore, it says that each person wants to go horseback riding for 3 hours:
5 people = 5(x dollars) x (3 hours) + 15 dollars
Now, we just need to convert this into an expression
5 people = 5(x)(3) + 15
5 people = 15x+15
They want the expression for cost, so we just need to give them
15x + 15
Answer:
4 number
Step-by-step explanation:
number of apples purchased to the cost of the apples
Let the walker’s speed be W, then the biker’s is W+1.5W=2.5W. Difference in speed is 1.5W. Distance=speed times time, so 12.5=1.5W×1.5=2.25W, and W=12.5/2.25=1250/225=50/9=5.56 mph. The biker’s speed is 2.5W=125/9=13.89 mph to 2 Dec places.
(Note: “1.5 times faster than a walker’s speed” could not reasonably mean the biker’s speed=1.5W because this would give W=16.67 mph, which is very fast for a runner, let alone a walker (!), and a biker’s speed of 25mph.)
Answer:
−4304
