Answer:
∠ Y = 34°
Step-by-step explanation:
Since XY = ZY then the triangle is isosceles and the base angles are congruent, thus
∠ X = ∠ Y , that is
6x - 23 = 4x + 9 ( subtract 4x from both sides )
2x - 23 = 9 ( add 23 to both sides )
2x = 32 ( divide both sides by 2 )
x = 16
Thus
∠ Z = 4x + 9 = 4(16) + 9 = 64 + 9 = 73° = ∠ X
Hence
vertex angle Y = 180° - (73 + 73)° = 180° - 146° = 34°
When you write logarithm of 1 with base b = x, through logarithm properties, that would be x to the power of b equals 1.

Now, from the law of exponents, any number raised to the power of zero is 1. Thus logarithm of 1 with base b is truly zero.

The larger number is 7 more than the smaller. Three times the larger number is 5 more than 4 times the smaller number. Find the numbers.
Step-by-step explanation:
1 day = $ 26.95
3 days = 26.95 × 3
= $80.85
Remainder = $100 - $80.85
= $19.15
1 mile = $ 0.27
= $19.15 ÷ $0.27
= 71 miles
