Answer:
<u><em>16 : 2 + 3 </em></u> (remember pemdas)
Step-by-step explanation:
Zoe is 16 years old. Her brother, Luke, is 3 years more than half her age. Write a numerical expression for Luke's age.
16 : 2 + 3 = 11
Answer: 17.5 or 35/2
Step-by-step explanation:
(If you change 4/5 to a decimal, it makes this easier. 4/5 would be 0.8.)
23.6 = (12 + x)*0.8
23.6 = 9.6 + 0.8x
14 = 0.8x
17.5 = x
17.5 as an improper fraction would be 35/2.
I think you are right but i am not sure
9 1/4
= 37/4
Therefore the reciprocal will just be the inverse which is...
=4/37
For this problem, we plug in the <em>numbers for t</em> and the <em>appropriate letters for e</em> to the equation <em>e = 300 - 10t</em>.
a) a = 300 - 10(-2)
simplify: a = 300 + 20
simplify: a = 320 ft.
But, this is not a viable point because when t≤0, she doesn't move anywhere, thus, should consistently be 300 ft.
b) b = 300 - 10(3.5)
simplify: b = 300 - 35
simplify: b = 265 ft.
c) c = 300 - 10(30)
simplify: c = 300 - 300
simplify: c = 0 ft.
