Step-by-step explanation:
there might be parentheses but this is what the expression would look like
Total distance the rover need to travel is
.
<u>Step-by-step explanation:</u>
We have , Garne Problem med . A rover needs to travel mile to reach its destination traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that how much farther does the rover need to travel , Let's do it step by step:
First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :
⇒
, where d is distance left to cover .
Now, rover need to travel 5/8 miles more to reach destination :
⇒
, where d is distance left to cover , So
⇒
⇒ 
⇒ 
⇒ 
⇒ 
∴ Total distance the rover need to travel is
.
Answer:
5, 17
Step-by-step explanation:
For this problem, you need to create a system of equations.
We can name one number x and the other y.
First equation: 2x + 7 = y
Second equation: x + y - 10 = 12, or x + y = 22.
We know y = 2x + 7, so we can substitute that into the second equation.
x + 2x + 7 = 22.
3x = 15
x = 5.
Plug x back into the first equation:
2 · 5 + 7 = y.
y = 10 + 7
y = 17.
Answer:
Step-by-step explanation:
Area of rectangle = length * width
= (3x + 2)(4x + 10)
= 3x *(4x + 10) + 2*(4x + 10)
= 3x *4x + 3x *10 + 2*4x + 2*10
= 12x² + <u>30x + 8x</u> + 20 {Combine like terms}
= 12x² + 38x + 20
