6400 meters_>3500 + 230t
It's greater than or equal to because the minimum is 6400 so the altitude can be higher and the pilot is gaining 230 meters per minute which is 230t and he started at 3500
Answer:
The length is 56 and the width is 54.
Step-by-step explanation:
The perimeter of a rectangle is 2x+2y (width and length on both sides). so 2x+2y=220. Also x=y-2, because the width is 2 feet less than the length. Fill x=y-2 in 2x+2y=220 and we get 2(y-2)+2y=220. 2y-4+2y=220. 4y=216. y=54. Fill in y=54 in 2x+2y=220 and we get 2x+2(54)=220. 2x=220-2(54)=112. x=56.
Answer:
C = 48.9
Step-by-step explanation:
C= 5F-160 /9
C= (5F -160)/ 9
Put F =120
C = (5(120) - 160)/9
C= (600 - 160)/9
C = 440/9
C = 48.89≈ 48.9
Answer:
e= 60
Step-by-step explanation:
we know that triangles add up to 180
so 35+24+2e+1= 180
simplify: 60+2e= 180
subtract 60 on both sides: 2e= 120
divide both sides by 2: e=60
The answer is 3. -1/2 n + 1 1/2 n add the coefficients to get 1n or just n. then n-n is 0 what is left is 3.
