Answer
x+3=17
Step-by-step explanation:
B - 13
Okay, we know that Mark brought 1 notebook and the totally is 6.91 while one pencil costs $0.42.
x= number of pencils he brought.
we know the price of 1 notebook + the cost of pencils times the numbers of pencils he brought = total cost.
So the equation will be:
1.45 + 0.42x = 6.91 subtract 1.45 on both sides.
0.42x = 5.46 Then we solve for x by dividing both sides by 0.42
x= 13
So the number of pencils he brought is 13.
3.17 is the answer and u can’t round to the nearest 10 cause it’s not necessary
Answer:
The value of sin X = 12 / 13
Step-by-step explanation:
Given
- The side opposite to angle ∠X = 12
To determine
sin X = ?
We know that the trigonometric ratio involving sin Ф such as
sin Ф = opposite / hypotenuse
Here:
- The side opposite of Angle X = 12
so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation
sin Ф = opposite / hypotenuse
sin X = 12 / 13
Therefore, the value of sin X = 12 / 13
C.I think its C because the 2 power is called square or 4 power.
