105x=6.50 (first ride)
30x=9 (second ride)
105x+30x=6.50+9
Answer:
Class 7A collected 4.8 ounces of pure gold.
Step-by-step explanation:
<u>Key skills required are: Percentages, Multiplication</u>
<u />
- We only need the information about Class 7A. They collected 40 oz that contains 12% gold.
- In other words, this means that 12% of that 40 oz gold sand is pure gold.
Here we have to do 12% x 40 to find the number of oz of pure gold. We first have to convert 12% into a decimal. Divide it by a 100 (or move the decimal point 2 places to the left) and you will get 0.12.
<em>Do 0.12 x 40 and you will get 4.8</em>
Therefore, there are 4.8 oz of pure gold in Class 7A's gold sand
Answer:
C. Scalene triangle
Step-by-step explanation:
What I would do is add all of the angles to 180 and then solve for x.
6x + 10 + 7x + 15x + 2 = 180
28x + 12 = 180
28x = 168
x = 6
Then, plug in 6 for each expression to find each angle
6(6) + 10 = 46
7(6) = 42
15(6) + 2 = 92
Since none of the angles are equal and one of the angles is over 90 degrees, triangle GFH is a scalene triangle
A - avocados, G - grapes, K - kiwis.
We know that: A = 3G, K = A - 0.75
So: G = A / 3
A + G + K = 16.75
A + A/3 + A - 0.75 = 16.75
7/3 A = 16.75 + 0.75
7/3 A = 17.50
A = 17.50 : 7/3
A = $7.50
G = 7.50 : 3 = $2.50
K = 7.50 - 0.75 = $6.75
Answer:
Prices of the fruits are A = $7.50, G = $2.50 and K = $6.75.
