Answer:
y= (100 - x) / 3 or y= (100/3) - (1x/3)
Step-by-step explanation:
1) subtract x
2) divide the entire equality by 3
3) Solve
The first car consumed 25 gallons of fuel while the second car consumed 30 gallons of fuel.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the first car consumption and y represent the second car consumption, hence:
x + y = 55 (1)
Also:
15x + 20y = 975 (2)
From both equations:
x = 25, y = 30
The first car consumed 25 gallons of fuel while the second car consumed 30 gallons of fuel.

Answer:
18
Step-by-step explanation:
If x = 2,
8x + 2
8 ( 2 ) + 2
= 18
Answer:
D
Step-by-step explanation:
using the definition of n
= 
where n! = n(n- 1)(n - 2)......× 3 × 2 × 1
here n = 7 and r = 4, hence
7
= 
= 
← cancel 3 × 2 × 1 leaving
7 = 7 × 6 × 5 × 4 = 840 → D
Answer:
(4,0,-7)
Step-by-step explanation:
The initial position was (0,0,0) since it was the origin
Now, we have a movement of positive x at a distance of 4 units, with a distance of z a total of 7 units(negative since downward)
The current position is thus;
(4,0,-7)
Thus correlates to (x,y,z) and our y has remained zero as there is no movement along the y-axis
