Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>The equations are:</u>
<u>Add up the equations to eliminate y and solve for x:</u>
- x - y + 2x + y = 2 + 13
- 3x = 15
- x = 15/3
- x = 5
<u>Now find the value of y:</u>
- y = x - 2
- y = 5 - 2
- y = 3
Answer:
Joey sold 6 cars
Step-by-step explanation:
Joey earns $350 per week + $200 per car he sells
The number of cars that he sold last week is unknown, so represent it with a variable, x.
Write an equation
$350 + $200x = $1,550
Subtract $350 from both sides of this equation
$200x = $1200
Divide both sides of the equation by 200
x = 6
Joey sold 6 cars
Hope this helps :)
<span> Start with the given equation
Subtract 6 from both sides.
Combine like terms.
Now let's graph </span>
Answer: Only one.
Step-by-step explanation:
We are given that in a triangle two side lengths of 10 centimeters and 8 centimeters. The angle between the sides measures 40°.
Suppose there is also a triangle with the same measures.
Then both the triangles are congruent by SAS congruence postulate.
Thus, every triangle with the given measurement are congruent to each other by SAS postulate.
Therefore, only one triangle can be possible with the given measurement.
