Answer: The correct answer is Choice C.
Step-by-step explanation: The cost of the ride is .50 per mile, plus $3.00 for each ride. In order to calculate it, the correct formula is going to multiply the number of miles, represented by x, by .50, and then add $3 for the ride.
Choice C is doing just that. $.50x + $3
The mistake the student made in the second procedure is she tried to solve 3.7+2.6 the same way she solved 4.3+8.4, which that way doesn't always work. You have to understand how decimals work when it comes to adding them. The right way to solve 3.7+2.6 and be sure you are accurate is to line the numbers up. Then add the numbers behind the decimal which is 7+6. That equals 13. So you would out your 3 and carry your 1 over to the number in front of the decimal. So 3+2=5, plus the additional one you had to carry. Your final answer would be 6.3
Answer:
x = 15
y = 10
Step-by-step explanation:
ΔTUR is a 60°-60°-60° triangle because all angles are equal and 180/3 is 60
therefore, the angle adjacent to ∡R is 120 because it forms a straight line (which measures 180 degrees)
that means that angles T and S (which are both 3y°) plus angle R equal 180 so you can set up this equation to find y: 120 +6y = 180
6y = 60
y = 10
Because angles T and S are the same we know that TR and TS are also the same, so RT is 15
ΔTUR is equiangular which means it is also equilateral; so if RT is 15 then UT and UR are 15 also
If UT = 15, we can write this equation: x - 5 = 15 and find that x = 20
