Answer:

$65

Step-by-step explanation:

So we already determined that the total cost C to drive m miles is:

$C=0.25m+40$

And we want to find the total cost of driving 100 miles.

So, substitute 100 for m and solve for C:

$C=0.25(100)+40$

Multiply:

$C=25+40$

Add:

$C=\$ 65$

Therefore, it will cost $65 to drive 100 miles.

50 + 4x
while that of B is
30 + 6x

Equating these two expressions,
50 + 4x = 30 + 6x
The value of x from the equation is 10.

Igoryamba

Answer:

$y = 2g - 2$

$y + g = 16$

Step-by-step explanation:

Given

Let g represent the green marbles

Let y represent the y marbles

Required

Determine the relationship between both marbles

The question says that y is 2 less than twice of g

This implies that: $y = 2g - 2$

The question further states that, Sarah has a total of 16 marbles;

This implies that $y + g = 16$

So, the system of equation that defines the relationship between y and g are:

y = 2g - 2

y + g = 16
