Answer: 4
Step-by-step explanation: 2 + 2 = 4
The desired answer is probably that
2x + 1 = 67
is the equation that can be used to solve the problem. In this case, x represents the smallest integer.
_____
I like to work problems in consecutive integers by considering their average. Here, it is 67/2 = 33.5. The two consecutive integers whose average is 33.5 are 33 and 34, the solution to the problem. For this, the first equation applies, where x is the value halfway between the two integers. (This answer (2x=67) would likely get marked wrong by your computer grading system.)
You can use estimation to find the product of two decimals by rounding both the decimal’s so the nearest tenth or tens place (depending on how long it is) and then multiplying the decimals.
for example, if you had 4.6 and 8.9, you have to round the 4.6 and 8.9. you round the 4.6 up to 5 because the 6 bumps the 4 up to 5) and then round 8.9 to 9 (because the 9 bumps the 8 up to 8.) then, multiply 5 and 9 and you get 45!
Answer:
18 miles
Step-by-step explanation:
Well, the problem did say a taxi ride costs $3 plus $2 for every mile. So, $39-3=$36, then, 36÷2=18 miles
Answer:
C.
Step-by-step explanation:
Let's solve your equation step-by-step.
25x2=16
Step 1: Divide both sides by 25.
