If the unknown number is x then the equation is:
25x/45=-65
Solution
5x/9=65
5x=-65*9
5x=-585
5x/5=-585/5
x=-117
1) 300miles X $0.20 = $60
2) $50 + $60 = $110
They spent $110 for the car.
Answer: A. x ≤ -3
x/3 - x-1/2 ≥ 1 would make x ≤ -3
1.1x=17.85
x=16.227272727272727...
Round to $16.23
Answer:
The base angles are 36° each
Step-by-step explanation:
An isosceles triangle is a triangle that has two of its sides and base angles to be equal.
If an isosceles triangle has a vertical angle of 108°, then the base angles will share the remaining angle in the triangle equally.
Since the sum of angles in a triangle is 180°
The remaining angle in the triangle = 180°-108°
= 72°
Since the base angles are equal, this remaining two angles will share angle 72° equally.
The base angles = 72°/2
The base angles = 36°
This shows that the base angles are 36° each.
