Answer:
145
Step-by-step explanation:
75% of 200 = 150
75% + 15% = 90%
100% - 90% = 10%
10% of 200 = 20
10% of 150 = 15
150 + 15 - 20 = 145
145 friends attended the party.
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: F=bill for first shop=4S-$630; S=bill for second shop
.
F+S=$3265 Substitute for F
4S-$630+S=$3265
5S=$3895
S=$779 ANSWER 1: The bill for the second shop was $779
.
F=4S-$630
F=4($779)-$630
F=$3116-$630=$2486 ANSWER 2: The bill for the first shop was $2486.
.
CHECK:
F+S=$3265
$2486+$779=$3265
$3265=$3265
