Answer:
255
Step-by-step explanation:
total cost paid = fixed cost + total variable cost
total variable cost = distance travelled x variable cost per unit
two equations can be derived from the question
a + 10b = 105 equation 1
a + 15b = 155 equation 2
a = fixed cost
b = variable cost per unit
Subtract equation 1 from 2
5b = 50
b = 10
Substitute for b in equation 1
a + 10(10) = 105
a = 105 - 100 = 5
a = 5
cost of travelling a distance of 25km
5 + 10(25) = 255
Answer:
The inequality is 
Step-by-step explanation:
Given : The isosceles triangle with base and side 4x+3, 2x+7.
And the perimeter is at least 137ft.
To write : An inequality for x
Solution : Let the base
and sides 
The perimeter of Isosceles triangle is 
where s=side and b=base
Now, we have given that perimeter is at least 137 ft.
Therefore, the inequality form is



Answer:
- 0.5 - 1.7 = - 2.2
Step-by-step explanation:
We need to add two numbers using the number line.
Steps to Add Numbers on the Number Line:
When we add a negative numbers that we move the point to the left of the number line.
We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.
So, we get 2.2 on the left.
2.2 is left side it means sign is negative.
Final answer is -2.2
