I got y=4x+9. Hope this helped
Answer:
Step-by-step explanation:
7(p+5)
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)
Hope this helps!
Let M be the age of Maggie and B the age of her younger Brother:
Rewrite the problem from English language to Math's:
B = 2.M - 10 (1)
and M + B = 29 (Given) OR B = 29 -M (2)
Plug 2) into 1):
29 -M = 2.M -10
29 + 10 = 3 M →→3M = 39 and M = 39/3 = 13
Replace M by 13 and you will find B =6
Then Maggie = 13 year old and her brother B = 6 year old
1 dozen = 12........so 12 dozen eggs is (12 * 12) = 144 eggs
she sold 5/6 of the eggs.....so she sold : 5/6 * 144 = 720/6 = 120 eggs
she gave her friends (144 - 120) = 24 eggs
(a) 12x = 120.....with x being the number of dozens of eggs
x = 120/12
x = 10 <== she gave away 10 dozen eggs
(b) she sold a dozen for 4.50....
4.50x = E .......x = the number of dozens of eggs sold and E = total earned. She sold 10 dozen...so sub in 10 for x
4.50(10) = E
45 = E <=== she earned $ 45 from the eggs she sold
