Answer:
Yes
Step-by-step explanation:
The answer is x=1.
Step one is Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
-2x + 2 = -2 • (x - 1)
Step two is
Equations which are never true :
<span> 2.1 </span> Solve : -2 = 0
Step three
Solving a Single Variable Equation :
<span> 2.2 </span> Solve : x-1 = 0<span>
</span>Add 1 to both sides of the equation :<span>
</span> x = 1
One solution was found :
<span> x = 1</span>
Answer:
13 quarters must be tails.
Step-by-step explanation:
Number of quarters = 40% of 50 coins
Number of quarters = 40/100 * 50 = 20 coins which are quarters.
35% of these 20 quarters on heads. We can proceed in 2 ways from here.
We can actually find the number of quarters that are on heads.
35/100 * 20 = 7 quarters are showing heads.
Since the other quarters must be tails 20 - 7 = 13 quarters must be tails.
The other way to do it is to realize that if 35% of the coins are heads, 65% of the coins must be tails 20 * 65/100 = 13 which is a bit more direct.
To compare decimals, start by looking at the whole numbers (the number to the left of the decimal). Since the number for both is zero, next move to the other side of the decimal, the tenths place. Both numbers are still zero, so now move to the next place over, the hundredths place. We have a 6 in the hundredths place for one of the numbers and a five in the hundredths place for the other one... We can stop right there... 6 is greater than 5 so the number with the 6 in the hundredths place is the larger number.

Answer:
80°
Step-by-step explanation:
Arc CB has the same measure as the central angle intercepting it. Angle COB measures 80°, so arc CB measures 80°.
