Let h represent the number of hours Liam must ride to beat his record.
distance-ridden + distance-to-ride ≥ record-distance
distance-ridden + (speed × time-to-ride) ≥ record-distance
4 +7h ≥ 32 . . . . . . . . an inequality representing the distance Liam wants
7h ≥ 28 . . . . . . . . . . subtract 4
h ≥ 4 . . . . . . . . . . . . . divide by 7
He must ride for more than 4 hours.
Answer:
60
Step-by-step explanation:
ratio: 12/6 =1/2 x/30=1/2 x=60
Answer:
Multiply/divide both sides by the same non-zero constant
Step-by-step explanation:
5x = 20
Divide each side by 5
5x/5 = 20/5
x = 4
Answer:
x=1.6
Step-by-step explanation:
.40=.25x
you move .25 to the other side which would look like this .40/.25=x and then you solve for x, which you would get 1.6.
Answer:
The redaction does not explain the situation. If we assume that 15 balloons were used to make one ballon poodle and three giraffes, then the answer would be 7,5 balloons for 1 poodle, and 2,5 balloons for a giraffe
Step-by-step explanation:
With 15 balloons we make 1 poodle and 3 giraffes. This means that 7,5 balloons were used to make 1 poodle, and other 7,5 balloons were used to make 3 giraffes.
If we divide 7,5 balloons between 3, we obtain 2,5. This means that with 2,5 balloons we make 1 giraffe
