Answer:
5.14
Step-by-step explanation:
The way i solved this was i found the length of the line by taking the 2 (Width and also "A") and the 7 (The height and also "B"), squared both of them and added them together. Then found the square root. Sense i suck at explaining things this is what the equation should have looked like. 
÷ 2. (Side wait for someone else to answer because i'm 70% sure this is right.
3/4(-10+2/5)
first do parenthesis
factor out -1 inside the parenthesis
3/4 * (-1*(10-2/5))
borrow from the 10
3/4 * (-1*( 9 5/5-2/5))
3/4 * -1(9 3/5)
change the mixed number to an improper fraction
3/4 * -1 ((5*9+3)/5)
3/4 * -1(48/5)
3/4 * (-48/5)
-144/20
divide by 4
-36/5
-7 r 1
-7 1/5
Answer:
The answer is C
Step-by-step explanation:
Answer: 20 6-cents, 30 8-cents, 10 10-cents and 2 20- cents
Step-by-step explanation:
6 cent = x+10
10 cent= x
8 cent= 3x
20 cent=2
6x+60+10x+24x+40
400 divided by 40=X
x=10.
10+10=20/ 6 cents
3x10=30/ 8 cents
x=10/ 10 cents
20 cents= 2.
