Answer:
x= -7/5 y=8/5
Step-by-step explanation:
1. choose a variable to eliminate (i chose 6)
2. multiply the first equation by 2 and the second equation by 3
3. now you have
-6x+6y=18
6x-21y=-42
and the x's can now cancel out when you add the equations together
4. after adding the equations, you get
-15y=-24
5. solve for y (y= 8/5)
6. now plug in 8/5 for the y in one of the original equations to solve for x. (i chose the first one)
7. -3x+3(8/5)=9
-3x+24/5=9
-3x=21/5
x= -7/5

Answer:
Step-by-step explanation:
an hour has 60 minutes, one third is 20 minutes, 2/3=40 minutes
Jordan bikes 8 2/3 mph or 26/3 mph
26/3 .......................60 minutes
?................................40 minutes
((26/3)*40)/60=52/9=5 7/9 miles in 40 min
<u>Answer:</u>
The area of the shape is 68 cm².
<u>Step-by-step explanation:</u>
We have to calculate the areas of the rectangle and triangle separately, and then add them together.
• Area of rectangle = length × breadth
= 30 cm × 2 cm
= 60 cm²
• Area of triangle = × base × perpendicular height
= × 2 cm × 8 cm
= 8 cm²
Adding the areas together = 60 cm² + 8 cm²
= 68 cm²
