Answer:
I think ots 15/8 or 1 7/8 mph
Step-by-step explanation:
if they walked it in 1/5 per hour then jist multiply 3/8 by 5/1 to get 15/8 mph
Look at the picture.
The triangle ADC and the triangle CDB are similar.
Therefore corresponding sides are all in the same proportion:
Answer: 4√3
Answer:
12 ≤ x - 7
Step-by-step explanation:
let "x" represent the number
The term decreased means subtraction.
The problem indicates that 12 cannot be greater than a number decreased by 7. Use ≤ which means less than or equal to.
≤ less than or equal to 12 means that 12 is the maximum value.
Step-by-step explanation:
as we can see that the sides are in the ratio of 2:1 and are consecutive
so
a;b=2:1
a=4
b=8
If you would like to calculate (a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1, you can do this using the following steps:
(a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1 = a^2 + 2 * a + 1 * a + 2 - (a^2 - 2 * a + 1 * a - 2) - a - 1 = a^2 + 3 * a + 2 - a^2 + 2 * a - 1 * a + 2 - a - 1 = 3 * a + 3
The correct result would be 3 * a + 3.
