Answer:5,-3
Step-by-step explanation:
If both triangles are congruent (that's what the sign means), then AD=CB, and CD=AB. Substituting what we are given into CD=AB,
6x-5=3x+10
Solving the equation:
3x=15
x=5
So we know that 2x+4 (the value of AD) becomes 2*5 +4, and you get 14. Since we know that AD=CB, then CB is also 14. No need to find y!
Answer: CB=14
Answer:
1.33
Step-by-step explanation:
7.98 divided by 6 = 1.33
6 goes into 7 once then 7-6= 1 bring down the 9. 6 goes in 19 3 times 19-18=1 bring the 8 down then 6 goes into 18 3 times.
(n+12)(n-7) = n^2 + 5n - 84
25% = 85 / 4 = $21.25 off
5% = 85 / 20 = $4.25
75% = 21.25 • 3 = $63.75
$63.75 + $4.25 = $68
Her total bill was $68
