Part A:
10p + 12v > 3200
p > 12000
v < 15000
(imagine they have the line underneath the symbols)
Part B:
at least 14,000 cups of plain yogurt
(make sure to convert the dollars to cents so that it is accurate)
math:
10p + 12(15000) > 320000
10p > 140000
p > 14000
Answer:
-3.4(2.7a-1.7)-1.2a= 47.3

Easy peasy
1.
d=number of dudes
l=number of ladies
total is 55 so
d+l=55
total cost is 75 so
2d+l=75
multiply first eeuqaiton by -1 and add to second
2d+l=75
<u>-d-l=-55 +</u>
d+0=20
d=20
sub
d+l=55
20+l=55
l=35

ratio and proportion
$87 is to 8 as is $x is to 5
87/8=x/5
times both sides by 5
435/8=x

around the edge
means perimiter
disregard how deep the pool is
60 feet long
x wide
P=2(L+W)
P=220
220=2(60+x)
divide 2
110=60+x
minus 60 both sides
50=x
it has to be 50 feet wide
4. monthly over 5 years

Answer: Let x = the measure of the larger arc and
let y = the measure of the smaller arc which is closest to the angle’s vertex. We know that x + y = 180 because that is given.
The secant-secant angle has a measure that is half the difference of the intercepts arcs. That means (1/2)(x - y) = 32 for this problem
We just need to solve the system
x + y = 180 and x - y = 64
Adding the equations you get 2x = 244 so x = 122 degrees and y = 58 degrees
