7) In this problem, we can see that both tangent lines to that circle come from the same point O.
So, we can write out the following considering that there is one secant line DO and one tangent line to the circle AO
Answer:
x=2
Step-by-step explanation:
1/2x+3=5/2x-1
1/2-5/2x=-1-3
-4/2x=-4
-2x=-4
x=-4/-2
x=2
Simple...
you have: 9u=10u-6
Isolate the variable-->>u
9u=10u-6
9u=10u-6
-10u -10u
-1u=-6
Now simply divide-->>
u=6
Thus, your answer.
2 consecutive integers.....x and x + 1
x + x + 1 = 61
2x + 1 = 61
2x = 61 - 1
2x = 60
x = 60/2
x = 30
x + 1 = 30 + 1 = 31
so ur 2 numbers are 30 and 31
Answer:
Money she have in 25 days = $2850
Money she have in 50 days = $5700
Step-by-step explanation:
Kristy earns each day = $134
Spends on breakfast & lunch = $8 + $12 = $20
Reaming about each day = $134 - $20
= $114
Money she have in 25 days = 25 x $114
= $2850
Money she have in 50 days = 50 x $114
= $5700
