Answer:
Equation: y = 15.5x
Step-by-step explanation:
Given that:
Time earns $31 for 2 hours
$46.5 for 3 hours
$62 for 4 hours
We will find unit rate first.
Unit rate = = $15.5 per hour
Now,
Let,
x be the number of hours
y be the total money earned by Tim
Total earning = Per hour rate * Number of hours
y = 15.5x
Hence,
Equation: y = 15.5x
Answer: 1/3x + 1/2
Step-by-step explanation: combine like terms. 1/3x + 2/3x - 2/3x = 1/3x
3/4 - 1/4 = 1/2
Therefore, the answer is 1/3x + 1/2
Answer:
9
Step-by-step explanation:
x² − 36 = 5x
x² − 5x − 36 = 0
(x − 9) (x + 4) = 0
x = 9 or -4
The answer is 30+70+5 and that is distributive property. Good Luck! Brainly Team
Height of the lamp post is 2.5 ft.
<u>Step-by-step explanation:</u>
AB = lamp post
CD = Julia
CE = Shadow
AC = 2 ft , CE = 5 ft , ∠AEB = 20°
AE = AC+ CE = 2+ 5 = 7 ft
Considering ABE as a right triangle, we can write the tan ratio as,
tan ∠AEB = opp/adj = AB/AE
AB = AE × tan ∠AEB
= 7 × tan 20°
= 2.5 ft
So, height of the lamp post is 2.5 ft.
