Answer:$27,57
1)find out how much wallets cost in the first month:
24,50 -100%
х - 125%
х= 24,50*125/100 ≈ 30,63
2)we will find out how much the wallets cost after the price is reduced by 10%:
30,63 - 100%
х -90%
х=30,63*90/100 ≈ 27,57

Answer:
See explanation
Step-by-step explanation:
In ΔABC, m∠B = m∠C.
BH is angle B bisector, then by definition of angle bisector
∠CBH ≅ ∠HBK
m∠CBH = m∠HBK = 1/2m∠B
CK is angle C bisector, then by definition of angle bisector
∠BCK ≅ ∠KCH
m∠BCK = m∠KCH = 1/2m∠C
Since m∠B = m∠C, then
m∠CBH = m∠HBK = 1/2m∠B = 1/2m∠C = m∠BCK = m∠KCH (*)
Consider triangles CBH and BCK. In these triangles,
- ∠CBH ≅ ∠BCK (from equality (*));
- ∠HCB ≅ ∠KBC, because m∠B = m∠C;
- BC ≅CB by reflexive property.
So, triangles CBH and BCK are congruent by ASA postulate.
Congruent triangles have congruent corresponding sides, hence
BH ≅ CK.
Answer:
-1/2 to the third power
Step-by-step explanation:
first you look and see -1/2 times -1/2 times -1/2 which is the same as -1/2 to the third power.
then if you have -1/2 to the 3rd power you just simply take -1/2*-1/2*-1/2 which is the same as the expression
16 7/8
.......................................................
Combine like terms (x's go with x's and y's go with y's) take the sign in from of the value and combine 8x+16x =24x and -9y+12y=3y (combine only works if the variables have the same exponent ( u can combine x and x(because they have an understood exponent of 1) but not x and x^3)
