Okay so here to find the answer you have to solve for any one by setting them in y=mx+b form 
y=-3x+7               x=-2y-16
2y=-x-16              6=-2y-16
x=6                      22=-2y
                           -11=y

Can someone please help me with 4 and 5 ???
Montano1993 [528]

Answer:

4. D  

A: -25.5=a

B: b=-4

C: c=12

D: d=8

Step-by-step explanation:

4.Between a and d they are the 2 bigger values but D was the greatest out of all of them. - divided by a - will result as a positive and 7/9=0.77 and 19/12 *I looked for the least common factor and multiplied numerator and denominator to 12 depending on the denominators value. Ex: since one of my denominators was 4, I multiply the whole fraction by 3 to get 9/12 and the other was 5/6 times 2 is 10/12 and just add 10/12 by 9/12 which is 19/12.

5.

A: All I did was multiply 8.5 and -3 and get -25.5=a.

B: I add 7 on both sides of the equation and -7 and 7 get canceled off and -11+7=-4. b=4.

C: I multiplied - to -3 and got 3, now I can subtract -3 on both sides. 15-3=12 so c=12.

D. I had to divide by 4 on both sides to get d by itself. 32/4=8 so final answer would be d=8.

Find the circumference of a circle whose area is 452.16 square meters ( ue 3.1416 as the value of
IrinaVladis [17]
Area of circle, πr² = 452.16

πr² = 452.16

r² = 452.16/π,            π ≈ 3.1416

r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997

Circumference  = 2πr

C = 2*3.1416*11.997

C ≈ 75.38

Circumference is ≈ 75.38 m.

Hope this helps.

What mixed number is equivalent to 18/8
sukhopar [10]
The mixed number to 18/8 is 2 and 1/4
To find this out you multiply 8 to get to 18, yet 8 only goes to 16 before going over 18, so 8 can multiply 2 times.
The 2 will be your whole number 
and since there is 2 numbers left (18-16=2) that would be the numbers left over giving you 2 2/8.
yet the 2/8 can be simplified to 1/4 giving you 2 1/4 as your answer.
Hoped this helped!
