Answer:
Step-by-step explanation:
Hello,
Pls post the full question next time so that we can make sure what is expected.
I assume that you want to solve for (x,y)
(1) 2x + 3y = 7
(2) 3x + 2y = 8
2*(2)-3*(1) gives
2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5
6x - 6x + 4y -9y = -5
-5y=-5
y = 1
and we can replace in (1)
2x + 3*1 = 7
2x = 7 - 3 = 4
x = 2
hope this helps
Answer:
Step-by-step explanation:
This is how to round 6.47 to the nearest tenth.
First note that 6.47 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

To round 6.47 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
Answer:
<h3>Minimum area: 6.75 km2, maximum area: 10 km2.</h3>
Step-by-step explanation:
We are given that a rectangle has length = 2km and width = 5km.
Formula for area is :
Area = Length × Width
Plugging values in above formula for area, we get
Area = 2km × 5km
On multiplying 2 and 5, we get 10.
Therefore,
So, the maximum area possible area is .
Therefore, you can choose correct option as:
<h3>Minimum area: 6.75 km2, maximum area: 10 km2.</h3>
