Answer:
-4.7
Step-by-step explanation:
I like to reverse the equation like so:
7.3-2.6=(positive 4.7)
then i know this will be my answer but just in the negatives. hope my little trick helped you!
The answer is c. 2/4..
When you simplify 2/4 you will get 1/2 ..
Hope it helps !!!
The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
Answer:
x=3800, y=4400
Step-by-step explanation:
X+y=8200 equation 1
15x+25y=167000 equation 2
x=8200-y isolate x in equation 1
15(8200-y)+25y=167000 substitute value of x from equation 1 into equation 2
123000-15y+25y=167000
10y=44000
y=4400
solve for x by inserting y value into either equation.
x+y=8200
x+4400=8200
x=3800
Check answer:
15x+25y=167000
15(3800)+25(4400)=167000
57000+110000
167000=167000
Second one because it don’t talk about minus when it talks about the three
