Answer:
The coefficient of
is 3.
Step-by-step explanation:
The coefficient of an equation is the number that is multiplied by the varible. In this equation,
is being multiplied by 3, so the coefficient is 3.
Answer:
See example below.
Step-by-step explanation:
The image of a triangle will be 5/6 the size. It will be slightly smaller than the original. For example, if the side measurement of the triangle on one side is 12 then the image of the triangle after a dilation will be 12*5/6 = 60/6 = 10.
The new side length is 10 slightly smaller than 12.
Please see the attached image for a visual representation of our scale factor. We can set up this proportion by taking the DVD cover and poster values and placing them in fractions. Cross multiply and divide to solve for x.
Answer: third one
Step-by-step explanation: if you do the equation you will see the result and will be equivalents to numbers higher or exact to 0.
Answer:
<h2>Frank speed = 37mi/h</h2><h2>Gregory speed = 59mi/hr</h2>
Step-by-step explanation:
Let the speed of Frank be x and speed of Gregory be y. If Gregory drives 22 miles per hour faster than Frank, then y = 22+x. SInce they they are 216miles apart after 2.25 hours,
Speed = Distance/Time
Total time travelled by them = 2.25hours
Total distance = 216 hours
Total speed = x+y = x+22+x
Substituting this parameters into the formula given to get x we will have;
x+22+x = 216/2.25
2x+22 = 96
2x = 96-22
2x = 74
x = 74/2
x = 37
<em>Hence the speed of Frank is 37miles per hour while that of gregory is 37+22 = 59miles/hour</em>
