  • The actual cost of the sweater is $18

The question says to evaluate the cost of four dollars less than the cost of a sweater.

To do this, what we have to do is to create a mathematical equation of it.

Less than always insinuates that we are to subtract, and as such, we are going to subtract four dollars from the cost of the sweater to get our final answer.

Four dollars less than the cost of a sweater that costs $22 is

22 - 4 = $18

The Miller family likes to paddle along the North River.
miss Akunina [59]

Answer:

4.7 miles per day.

If number two is meaning to add 4.7(.5)= 2.3(3) plus the original 14 miles over a three day travel from number one. Then the total distance for the six day trip would be 14+ 2.3(3)= 20.9

If it is meaning a total of 6 days traveling at half the speed

4.7÷2= 2.3 2.3 × 6= 13.8 miles

Answer by macston (5194) About Me  (Show Source):

You can put this solution on YOUR website!

If 37% get less than 8 hours of sleep, 100%-37%=63%

63% get 8 hours or more per night:

(0.63)(2200)=1386

ANSWER: You would expect 1386 to get 8 or more hours of sleep per night.

   This is an equation! Solutions: x=1.

   Graphical form: Equation 3%2Ax-x%2B2=4 was fully solved.

   Text form: 3*x-x+2=4 simplifies to 0=0

   Cartoon (animation) form: simplify_cartoon%28+3%2Ax-x%2B2=4+%29

   For tutors: simplify_cartoon( 3*x-x+2=4 )

   If you have a website, here's a link to this solution.

Solve for x<br> 45 degrees<br> 90 degrees<br> 65 degrees<br> 85 degrees
Mrrafil [7]

Answer:

x = 45

Step-by-step explanation:

x and (90 - x) are alternate exterior angles and are congruent , then

x = 90 - x ( add x to both sides )

2x = 90 ( divide both sides by 2 )

x = 45

Amir and Marvin continue until they each flip a coin
Ahat [919]

We are told that each person flips a coin 200 times. We know that a coin has two options when heads or tails fall, therefore, the results between Amir and Marvin are compared with the number of heads and the number of tails that each one obtained.

The theoretical probability says that out of 200 times a coin is flipped by having 50% heads or tails come out, 100 must be heads and 100 must be tails, theoretically obviously speaking.

Therefore with these values it would be the comparison.
