Answer:
A is the answer
12 in
first substitute the variables
then 78=1/2h(5 + 8)
this makes it an equation
add similar terms which equals to
78=1/2xhx13
then divide both sides by 13
6=1/2xh
lastly divide both sides by 1/2
12=h
Step-by-step explanation:
proof
A=1/2x12(5 + 8) then
A=1/2x12x13 then
A=6x13 then
A= 78in^2
Change pounds to ounces.
1 pound = 16 ounces.
4 x 16 = 64 + 6 = 70 total ounces of clay.
Now divide by 10:
70 / 10 = 7
Each part was 7 ounces.
13 x 6 = 78 you cant multiply anymore so that's how many times it can go in 80.
Answer:
-3/2, -1
Step-by-step explanation:
Each coordinate contains one
value and one
value,
.
If we work out the midpoint of each of these individually, it makes it much easier to find the midpoint of the line.
Let's take the
values first. Our first
value is -4 and our second
value is 1. Imagine the integers between -4 and 1 laid out in a sequence:

If you take the middle value of this sequence, you get the midpoint of the
values.
In this case, the middle is between values -2 and -1, leaving us with a midpoint of -1.5. This as a fraction is
.
Now let's look at the
values. Our first
value is 2 and our second
value is -4. Again, let's imagine those numbers laid out in a sequence:

Here, the middle of these values is -1, and this is the midpoint of the
values.
So if we put these two values in a coordinate, we get the midpoint of the line.
In this case, we get
.
-4a - 6 = -12
-4a = -12 + 6
-4a = -6
a = -6/-4
a = 6/4
a = 3/2
a = 1 1/2
The answer is c
