The questions that are 1-6 above:
Use the term
P- Parenthesis
E- Exponents
M-Multiplying
D-Dividing
A- Addition
S-Subtraction
Do the equations from that order doing Parenthesis first, Exponents second, etc.
If there's none of one of the operations, skip to the next one. Remember to solve the equation starting from parenthesis and then going down the order.
Sorry I can't help you with the bottom 1-6 Good luck
5. a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse
7^2 + 10^2 = c^2
49 + 100 =c^2
149 = c^2....take square root of both sides, eliminating the ^2
sq rt 149 = c
12.21 = c.....so the approximate length of 3rd side is 12 m
6. x = number of books bought
7. m < 2 + m < 8 = 180
8. 1000 = 400 + 24x
1000 - 400 = 24x
600 = 24x
600/24 = x
25 = x <=== 25 months he will have spent $ 1000
Is this the original question or?
B. 107 bc 26.5+34.2= 60.7+45.8= 106.5 round that to be 107.
11,513 is the answer I really don't know how to write it all out sorry
