The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
If the temperature at 1:00 is x, then Jonestown's temperature at 3:00 is
x-10-8 (since it dropped 10 degrees then 8 more degrees)=x-18
Using x for Cooperville too, we get x-6-2 (since it drops 6 degrees then 2 more degrees) = x-8
Since -8 is greater than -18, Cooperville's temperature is warmer and Jonestown's temperature is lower aka colder<span />
This is simple multiplication
do 2*4 and 10*4
so you get f(x)=8 and x=40
if you wanna do it by doing division do
2=10
f(x)=40
cross multiply then divide
so do 2*40 to get 80
then do 80/10 to get 8
Answer:
1).Sugar used in 7 days = 61.25 pounds
2). Total cost of 9 cupcakes = $38.25
Step-by-step explanation:
1). Alani uses 8.75 pounds of sugar each day.
So, sugar used in 7 days = Amount of sugar used in one day × Number of days
= 8.75 × 7
= 61.25 pounds
2). Since, each cupcake costs $4.25
Number of cakes ordered = 9
Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes
= 4.25 × 9
= $38.25
The lines intersect at the point 
Explanation:
The given two equations are 
and 
We need to determine the whether that they intersect.
To determine the point of intersection, let us solve the equation by substitution method.
Let us equate both the equations.
Thus, we have,
Subtracting both sides by x, we get,
Simplifying, we have,
Dividing both sides by -3, we get,
Substituting in the equation , we get,
Thus, the lines intersect at the points and
Hence, the lines intersect at the point
