Answer:
Infinite
Step-by-step explanation:
3(4x + 1) - 2
= 12x + 3 - 2 (Multiply the sum in the bracket by 3)
= 12x + 1 (Simplify)
This means that:
12x + 1 = 3(4x + 1) - 2
is the same as
12x + 1 = 12x + 1
Hence, anything that is used to substitute x is correct.
Let the variable n represent the number
- Less eleven means subtract eleven from the variable
<u>➪</u><em>Thus, The equation is (n-11)</em>
1/50 of a mile is the distance the snail goes in 50 minutes. To get an hour, the snail must move for another 10 minutes (60-50=10).
Dividing 1/50 mile by 5 gives us 0.2/50 mile, which would be what the snail travels in 10 mins.
This can be added to 1/50 to give 1.2/50 mile as the answer
OR
You can take 0.2 and times it by 6 (to get 60 minutes from 10 minutes) to give the same answer as above.
Either way, the snail has gone 1.2 miles after the hour has passed.
B) right angle triangle
angles in a triangle add up to 180 degrees
31+59=90
180-90=90
90 degrees is a right angle
