Answer:
<u>Length of 1 piece= Length of total divided by 8</u>
Step-by-step explanation:
Length of total= 5.24 feet long
Width of total= 1.34 feet wide
Width is divided by 1 line so, there are 2 parts.
Width= 1.34 divided by 2
Width= 0.67 feet wide
Length is divided by 7 lines, so there are 8 parts.
Length= 5.24 divided by 8
Length=0.655 feet long
They are asking for formula to find the length of each piece
<u>Length of 1 piece= Length of total divided by 8</u>
<u></u>
Hope that helps!
Answer:
The correct answer is A. 167 milliliters of 7% solution and 333 milliliters of 4% solution and here is how:
If x is the number of milliliters of the 7% saline solution and y is the number of milliliters of the 4% saline solution then add up to 500 milliliters total, so x + y = 500.
and if we do
x + y = 500
x = 500 - y
0.07x + 0.04y = 25 (substitute 500 - y for x)
0.07(500 - y) + 0.04y = 25
35 - 0.07y + 0.04y = 25
-0.03y + 35 = 25
-0.03y = -10
y = 333.333...
y = about 333
x = 500 - y = 500 - 333 = 167
Then you know why the answer is A.

Step-by-step explanation:
treat it as a normal equation
Answer:
x/2 + 11
Step-by-step explanation:
"half a number", implies that you are dividing by 2, or "halving the number".
"11 more", implies that you are adding 11.
