Answer:
x= -15/2 y=-33/2
Step-by-step explanation:
i dont know how you want to solve it but if it is "system of equations" then first solve for the first variable in on e of the equations, then substitute the result into the other equation.
The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:
3(20) + x = 79
x = 19 miles
The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

Answer: -4
Step-by-step explanation:
2.5x = -10
1. divide -10 by 2.5
2. x = -4
A ton weighs 2000 pounds, so if you were to take 6 tons, it will be 12000 pounds.
18. The shape is only shifted to a different location and orientation but remains the same size so this is congruent.
19 and 20 are both scaled to a different size so they are both similar.
