4. Probability
Answer:
Step-by-step explanation:
3(0.5x-4)=3/2x-1.2
We simplify the equation to the form, which is simple to understand
3(0.5x-4)=3/2x-1.2
Reorder the terms in parentheses
+(+1.5x-12)=/2x-1.2
Reorder the terms in parentheses
We move all terms containing x to the left and all other terms to the right.
0=0
We simplify left and right side of the equation.
0=0
0=0
This equation is an identity, so all real numbers are solutions.
Answer:
$22
Step-by-step explanation:
17.99 round up so 18
a second large pizza is 14 dollars off of the original price of 18 so 4
18+4 is 22
so 2 large pizzas would cost $22
Step-by-step explanation:
Find 1 pack of pencil:
1 pack = 10 ÷ 5 = $2
9 packs = 2 x 9 = 18
Answer: $18
The arc length is the product of the angle measure in radians and the radius.
... s = r·θ
So, the angle in radians is the ratio of arc length to radius.
... θ = s/r
To convert from radians to degrees, multiply by the conversion factor 180°/(π radians).
... y = s/r·(180°/π)
Then the angle is between
... 15/20·180/π ≈ 42.97
and
... 16/20·180/π ≈ 45.84
Suitable integers in this range are 43, 44, and 45.
One possible integer value of y is 44.
