A would equal 4 because you would first convert the mixed numbers into improper fractions, then move the constant to the right, and finally add the factions
a-2(1/2)=1(1/2)
a-(5/2)=(3/2)
a=(3/2)+(5/2)
a=4
Hope this helps! sorry if it is kind of dark
Answer:
3, 8, 13, 18, 23
Step-by-step explanation:
The recursive definition tells you the first term is 3, and that each successive term is 5 more than the one before. 5 terms are ...
3, 8, 13, 18, 23
at a map scale of 1:1500, 12 centimeters on the map is equivalent to 1.8 kilometers on the ground.
step-by-step
since the scale is 1 to 15,000 you simply multiply it by the 12 cm
12cm × 15,000 = 180,000
but you still have to convert it to kilometers (the measurement on the ground).
to go from centimeters to kilometers move the decimal 5 place values to the left.
<u>final</u><u> </u><u>answer</u>
1.8 kilometers
You would do 56 centimeters times 1 inch per 2.54 centimeters times 1 foot per 12 inches.
Mathematically, it will look like (56 * 1) / (2.54* 12) = approximately 1.837
In sentence form: There are approximately 1.837 feet in 56 centimeters.
