-5(11-3t) = -6t -4
distribute -5 to the parentheses
-55+15t = -6t -4
isolate t; add -6t from both sides
-55+21t = -4
add 55 from both sides
21t = 51
divide t
t = 2.4 (rounded)
Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
Yes, very fun, not
ok
one way is table or
solutions amount x and y
x+y=500
x=25%
y=50%
0.25x+0.5y=0.35(500)
we have
x+y=500
0.25x+0.5y=0.35(500)
0.25x+0.5y=175
solve
multiply second equation by 100
25x+50y=17500
divide everybody by 25
x+2y=700
now we have
x+y=500
x+2y=700
multiply first equation by -1 and add to second equaiton
-x-y=-500
<u>x+2y=700 +</u>
0x+1y=200
y=200
sub
x+y=500
x+200=500
x=300
300L of the 25% and 200L of the 50%
