First you know that at 6 it was 75 degrees. Now it’s noon and the temperature is 18 degrees warmer. So when you add 75 and 18 you get 93 degrees. When the storm rolls in at 4 it says that your temperature dropped 21 degrees. So you need to subtract 21 from 93 (93-21) which will get you at 72 degrees at 4pm
Answer:
Option A: Madison, (1.2,-1.6) is the correct answer.
Step-by-step explanation:
Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4
While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)
So <u>Madison's solution is wrong. </u>
Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)
The value of x=1.2 is correct, we have to find the value of y
So,
Putting the value of x=1.2 we get,
The solution of given system of equations is (1.2,-1.6)
Hence,
Option A: Madison, (1.2,-1.6) is the correct answer.
Okay, so your scale rectangle has a length of l = 8.2 cm. The actual triangle has a length of L = 41 cm. What is the scale factor? You find out by dividing the scale rectangle l from the actual rectangle L.
41 cm / 8.2 cm = 5
The scale factor is 5. That means the actual rectangle is exactly 5 times bigger than the scale rectangle. Now finding the width is easy! If the width of the scale rectangle is 2.1 cm and the scale factor is 5, you just multiply them together!
2.1 cmx 5 = 10.5 cm
The width of the actual rectangle is 10.5 cm! Hope that helps!

Yes frist you add 3x+8+62 = 5x+50
Answer:
Jim's statement is correct for positive numbers
Explanation:
Flooring means that we will take the number before the decimal point. This number should be the whole number that precedes the given decimal.
Now, let's check:
1- positive numbers:
Take 3.5 for example:
Taking the number directly before the point ......> we would have 3
The whole number that directly precedes 3.5 is .......> 3
Since they are both the same, therefore, Jim's statement is true
2- negative numbers:
Take -3.5 for example:
Taking the number directly before the point ......> we would have -3
The whole number that directly precedes 3.5 is .......> -4
Since they are both not the same, therefore, Jim's statement is false
Hope this helps :)
