Answer:
proportional bc all of them are 1 shirt = 12.95
Hello!
The sum of 5/6 and 1/2 is 1 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
The difference of 5/6 and 1/2 is 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 - 1/2 = 1/2
Hope this helps!

Answer:
The value of x is 2 and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- -7x + y = – 19
- -2x + 3y = – 19
<h3><u>To </u><u>Find</u>;</h3>
<h3><u>B</u>y<u> </u><u>Usin</u>g<u> </u><u>Elimination</u><u> </u><u>Method</u>;</h3>
First name the equation
- -7x + y = – 19 ...(1)
- -2x + 3y = – 19 ...(2)
Now, Multiply equation (1) by 3 we get,
3 × (-7x + y = – 19)
-21x + 3y = – 57
Now, Eliminate
-21x + 3y = – 57
-2x + 3y = – 19
<u>+</u><u> </u><u> </u><u> </u><u> </u><u>–</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+</u><u> </u><u> </u><u> </u><u> </u>
-19x = -38
x = -38/-19
x = 2
Now, Put the value of x in equation (2) we get the value of y.
-7x + y = – 19
-7(2) + y = – 19
-14 + y = -19
-14 + 14 + y = -19 + 14
y = -5
Thus, The value of x is (-5) and the value of y is 2.
<h3>
<u>For </u><u>Verification</u>;</h3>
-7x + y = – 19
-7(2) + (-5) = – 19
-14 – 5 = – 19
-19 = -19
-2x + 3y = – 19
-2(2) + 3(-5) = – 19
-4 – 15 = – 19
-19 = -19
Here, L.H.S = R.H.S
Hence Verified!

In 1 meter there are 1,000 millimeter.
When you go from small (mm) to big (m) you always divide the small (mm) by what the equivalent of 1 big (m) but in terms of the small (mm)
^^^That's a bit confusing so I will work it out so it makes more sense...
^ this is the equivalent to 1 meter (the big in this case)
3 m = 3,000 mm
Hope this helped! Let me know if there is anything else that I can do!
-3x from both sides so it looks like 2x=20 and divide by 2 and x=10
