Answer:
6 ÷ (2 ÷ 3)
Step-by-step explanation:
Use division in both.
6 ÷ (2 ÷ 3)
6 × (3 ÷ 2)
18 ÷ 2
9
Answer:
x=17
Step-by-step explanation:
7x and 2x+27 are supplementary meaning they add up to be 180 degrees.
so, 7x + 2x + 27 = 180
9x + 27 =180
9x = 153
x = 17
hope this helped
Answer:
$138
Step-by-step explanation:
Let the money with Raymond be $y
Let the cost of 1 tshirt be $x
then cost of 8 tshirt = cost of 1 t-shirt*8 = 8x
Raymond wanted to buy 8 t-shirt but he was short of $8.10
It means that 8x is equal to money he had plus $8.10
thus,
y + 8.10 = 8x
y = 8x - 8.10
Next situation
cost of 5 t-shirt = 5x
. instead he bought 5 T-shirt and had $12.60 left,
it means cost of 5 T-shirt plus $12.60 = total money Raymond had
y = 5x + 12.60
comparing y in both the equation
y = 8x - 8.10 and y = 8x - 8.10
5x + 12.60 = 8x - 8.10
=> 8x-5x = 12.60+8.10
=> 3x = 20.70
=> x = 20.70/3 = 6.9
Thus, cost of 1 T-shirt = $6.9
cost of 20 T-shirt = 20*$6.9 = $138 (Answer)
quadrant 3 I believe. I hope so at least dudski

The geometric mean of two numbers has us do two steps in this order
- Multiply the values
- Apply the square root
The geometric mean can be applied to more than two values. Regardless of how many values you have, you always multiply them out. However, the number of values will tell you what kind of root you'll take (eg: 3 values leads to a cube root; 4 values means you'll take a fourth root, etc).
