Answer:
Step-by-step explanation:
(7/8) to the negative power is 8/7
as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
There are many ways to work this out. One way could be:
Add up:
1/4 + 1/4 + 1/4 = 3/4
Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6
Find what's remaining:
8 - 6 = 2
So Mr.Greg has sandwiches left.

Answer:
Y = 3 - 2x
Step-by-step explanation:
The function j(x)=39x is the number of jumping jacks you can do in x minutes how many can you do in 5 minutes'?
This is asking you to evaluate the function when x is 5...so all you do here is substitute 5 for x and simplify.. since the question defines "x" as the number of minutes...and j(x) represents the number of jumping jacks.
j(x) = 39x
j(5) = 39(5)
j(5) = 195 <--- answer...
So you do 195 jumping jacks in 5 minutes
I really hope this helps :)
