The equation you would use is 
mean= Test1+test2+test3+test4+test5+Test6+x/Total number of tests

so 83=89+78+69+81+89+90+X/7
First mutiple both sides by 7 so 
581=496+X
you then substract the 496 and get 85
so she would need a 85 on the 7th test

Somebody please help me with my geometry
RSB [31]

Answer:

AB + BC = AC

BC = AC - AB

5x + 6 = 37 - (2 x + 3) = 37 -2 x - 3 = 34 - 2 x

7 x = 34 - 6 = 28

x = 4

BC = 5 x + 6 = 5 * 4 + 6 = 26

Check:

AB = 2 x + 3 = 2 * 4 + 3 = 11

AB + BC = 26 + 11 = 37

What is the value of g?<br> -5+7g=3g+ 9
Xelga [282]

Answer:

g = 7/2

Step-by-step explanation:

-5 + 7g = 3g + 9

~Add 5 to both sides

7g = 3g + 14

~Subtract 3 to both sides

4g = 14

~Divide 4 to both sides

g = 14/4 or g = 7/2

Best of Luck!

Thank you sooooooooooooo. Much
Maksim231197 [3]

Answer:

24 inches

Step-by-step explanation:

Similar to the question you asked earlier, this question also has 3 small rectangles and we can combine it to make it a one big rectangle. The equation for the perimeter is this:

2W + 2L = P

We know W and P (the width of the small rectangles times 3), thus plugging in those values would give us:

2(30*3) + 2L = 324

180 + 2L = 324

2L = 144

L = 72

We need to divide this number by 3 to get the length of the small rectangle, which would give us 72/3 or 24.
