Answer:
x= 7
y=9
z=90
Step-by-step explanation:
8x = (9x-7)
8x = 9x-7
8x - 9x= -7
-x= -7
<em>(multiply -1 to each side to make it positive)</em>
x= 7
(5y-11)+(9x-7)=90
5y-11+9(7)-7=90
5y-11+63-7=90
5y+63-18=90
5y+45=90
5y=90-45
5y=45
y=45÷5
y=9
(5y-11)+8x+z=180
5y-11+8x+z=180
5(9)-11+8(7)+z=180
45-11+56+z=180
34+56+z=180
90+z=180
z=180-90
z=90
<u>Answer:</u>
3 miles 26 yards
<u>Step-by-step explanation:</u>
We are to perform subtraction on the following:
8 mi 133 yd 2 ft – 5 mi 107 yd 2 ft
We have to divide the amount of miles from miles, yards from yards and feet from feet. So a good idea is to write it this way in order to avoid any confusion:
8 mi 133 yd 2 ft
- 5 mi 107 yd 2 ft
_______________
3 mi 26 yd 0 ft
_______________
So we are left with 3 miles 26 yards.
Answer:
Step-by-step explanation:
Good question. It is important to know the answer.
The 9 means that there are a total of 20 objects. You want to select just 9 of them.
The situation is well described by C.
I might be wrong but, I would say about 32.6 miles a day. This could be wrong.
