Since it went 8 floors in 6 seconds you divide. 8/6 is 1.333 or 1 1/3 floors per second. Hope this helps.
Answer:
A= 29
B=34
C=117
Step-by-step explanation:
<u>A triangle has three sides and a triangle always adds up to be 180</u>
A + B + C = 180
B = A + 5
C = 4A + 1
Plug in.
A + A + 5 + 4A + 1 = 180
6A + 6 = 180
6A = 174
A = 29
<u>Now since you found A, find the other two by plugging A in!</u>
C = 4(29) + 1
C = 117
<u>Plug in the B equation</u>
B = 29 + 5
B=34
Check your answers
29 + 117 + 34 = 180
15) x^2-2x-8=1/4x-1
x^2-2.25x-7=0
4x^2-9x-28=0
(x-4)(4x+7)=0
x-4= 0 or 4x+7=0
x=4 or x= -7/4=-1.75
16) answer hides in the f(x) equation
the trick is to think of the value that will make the (x-4) =0 and and the y value can be directly plugged off from the +c
therefore, ans is x=2 y= 4
(2,4)
Answer:
x = 4
Step-by-step explanation:
x * 5 = 20 * 1
x = 4
