Answer:
x = 23
Step-by-step explanation:
Δ ABC and Δ DEF are congruent by the SAS postulate, thus corresponding sides are congruent, that is
BC = EF, substitute values
x - 4 = 19 ( add 4 to both sides )
x = 23
Hello
DEF and IKL , equilateral =>
DE = 5x-12 = 3x-4
5x-3x= -4+12
2x= 8
x=4
DE = 5x-12 = 20-12 = 8
KL = 3x+24 = 10x+3
24 -3 = 10x-3x
21 = 7x
x= 21/7 = 3
KJ = 10x+3 = 30+3 = 33
Total number of loaves sold = 9360 + 2640 = 12000
Number of loaves of whole wheat bread = 2640
Percentage of loaves of whole wheat sold = 2640/12000 x 100 = 22%
Answer: 22%
I believe the answer is -10y - 4
Happy I could help!!
