A race car travels 1,212 kilometers in 4 hours. what is the car's rate of speed?
Answers
Answer 1
Answer:
The car's rate of speed is precisely 1,212 km per 4 hours.
If you're more comfortable with a unit rate, then simply
perform the division:
1,212 / 4 = 303
1,212 / 4 km/hr = 303 km/hr
The car's rate of speed is precisely 1,212 km per 4 hours.
If you're more comfortable with a unit rate, then simply
perform the division:
1,212 / 4 = 303
1,212 / 4 km/hr = 303 km/hr
Answer 2
Answer:
The car's rate of speed is 303 kilometers per hour.
1,212 kilometers/4 hours / 4/4 = 303 kilometers/1 hour
1,212 kilometers/4 hours / 4/4 = 303 kilometers/1 hour

On the number line you would start with 2 and end at 20 so your space would be 10 and your number sentence is 2×10=20

the answer is x=4. you have to use the distributive property on both sides then begin solving for x.
Use the distributive property to get 10x+20=5x+40. Subtract 5x from both sides to get 5x+20=40. Subtract 20 from both sides to get 5x=20. Divide 5 from both sides to get x=4.
x=4
x=4

it would be 429 because 5 or more go next door for or less home is best. and 8 is greater then 5
Since you're rounding to the nearest whole number, you use the tenths place to determine how to round it. 6 ≥ 5 so the ones place is rounded up, making 429 your answer.

I would estimate it as (300 x 7) = 2100
Then I would subtract (11 x 7) + 77 from that to get the exact answer of 2023

I didn't use a calculator or paper. The 'trick' is to notice that 289 = (300 - 11)

I didn't use a calculator or paper. The 'trick' is to notice that 289 = (300 - 11)
I was taught to round it up to the nearest ten, then multiply it like this,
289, rounded up is 290, then seperate the number, (200 + 90)
200 X 7 = 1400 (multiply the numeral, then add the zeros)
90 X 7 = 630 (repeat the same process)
1400 + 630 = 2030 (actual answer = 2023)
