SOLUTION:
Step 1:
In this question, we are given the following:
What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?
A. (-3.5, 1)
B. (1.5,-4)
C. (-4,1.5)
D. (1.-3.5)
Step 2:
The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

Flour to sugar....u have 3 1/2 cups of flour and 1 1/4 cups of sugar (not sure if u mean brown or granulated...but either way, they are the same)...so ur ratio can be 3.5 cups to 1.25 cups.....or it can be 7/2 cups to 5/4 cups...depends on if u want it in decimals or fractions.
to compare the 2 quantities....um...3 1/2 cups flour > 1 1/4 cups sugar
======================
how many cups of flour do u need for each egg....
3 1/2 cups of flour.....and 2 eggs
(7/2) / 2 =
7/2 * 1/2 =
7/4 or 1 3/4.....so u need 1 3/4 cups of flour per egg <==
========================
I am having trouble reading ur rate table....but if 3 dozen (36 cookies) requires 2 teaspoons, then....
cookies : 6 12 18 24 30 36 180
vanilla : 1/3 2/3 1 1 1/3 1 2/3 2 10
the strategy used was a proportion : 36/2 = (number of cookies) / x...I just subbed in number of cookies and solved for x (number of teaspoons).
=======================
How many cookies do u need to sell to earn at least 60% of 120 ? and 40% of 120 ?
so if this relates to ur other question....then u r selling ur cookies at 1.60 for 4 cookies.....that means 1.60/4 = 0.40 per cookie
60% of 120 = 0.60(120) = 72
0.40x > = 72
x > = 72/0.40
x > = 180.....u would have to sell at least 180 cookies
40% of 120 = 0.40(120) = 48
0.40x > = 48
x > = 48 / 0.40
x > = 120....u would need to sell at least 120 cookies
Answer:
12
Step-by-step explanation:
For these problems you should use the pythagorean theorem: a^2+b^2=c^2
In this case, 13=c and 5=a
so:
5^2+x^2=13^2
25+x^2=169
subtract 25 from both sides
x^2=144
√144=12
missing side=12
Answer:
x=0
