Answer:
1.06x
Step-by-step explanation:
The original price of a carrot cake is represented by x.
Emily increased the price of carrot cakes at her bakery by 6%.
We need to find an expression that represents the price of a carrot cake after the increase.
Price = x+6% of x
![=x+\dfrac{6}{100}x\\\\=x+0.06x\\\\=1.06x](https://tex.z-dn.net/?f=%3Dx%2B%5Cdfrac%7B6%7D%7B100%7Dx%5C%5C%5C%5C%3Dx%2B0.06x%5C%5C%5C%5C%3D1.06x)
Hence, the required equation is "1.06x".
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66

Answer:
JK got 30 answers correct on a 50 item test.
Step-by-step explanation:
It is given that:
Total items on test = T = 50
Fraction of total items that were answered correctly = 3/5
We simply have to multiply the total number of questions by the fraction of correct answers.
So,
The correct answered number of items are:
![= \frac{3}{5} * 50\\=30](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3%7D%7B5%7D%20%2A%2050%5C%5C%3D30)
Hence,
JK got 30 answers correct on a 50 item test.
