Answer:
x=5.5
Step-by-step explanation:
Perimeter of ABCD=85
The perimeter is everything around the outside added together.
Form an equation:
3x+4+4x+6x-11+5x-7=85
Collect the like terms:
Like terms are terms that have the same powers and coefficient.
3x+4x+6x+5x=18x
4-11-7= -14
Put it back into an equation:
18x-14=85
Do inverse operations to find out what x is:
85+14=99
18x=99
99÷18=5.5 (we divide because, in algebra, when a number is next to a letter, it means times and as we want the inverse, you would have to divide)
x=5.5

Answer:
Expanded, the answer would be 10b + 40
Step-by-step explanation:
Just multiply 8 to 2b and 8
Answer:
A-
First we do 72/88 to get the percentage. When the math is done you get 81.81% so that means that Will got an 81.81% on the test.
B-
Now we will do 81/88 to get the percentage because Cheng got 81 points. When that math is done we see that Cheng got a 92.04% on the test.
C-
To get Rob's percentage we need to do 75/88 because Rob got 75 points. When we calculate that we recieve 85.23% meaning he got that on the test.
D-
Now to figure out who got the highest percentage and who got the lowest is simple. The max points doesn't change so it varies on who got the highest and lowest points. We can see that Cheng received the highest with 81/88 (92.04%) and Penny received the lowest with 68/88 (77.27%).
Where is the rest of the problem
