Answer:
15 sq. cm.
Step-by-step explanation:
Each of the full squares are 1 so each of the half squares are .5
There are 12 full squares and 6 half squares. If you add those half squares you will get 15 sq. cm.
Answer:
x = 3
y = -5
Step-by-step explanation:
It would be very easy to eliminate y by adding the two equations,
4x - 7y = 47
<u>6x + 7y = -17</u>
10x = 30
x = 3 4(3) - 7y = 47
12 - 7y = 47
-7y = 35
y = -5
Check: See if the values work in the second equation
6(3) + 7(-5)
= 18 - 35
= -17 It looks like they work, so we know we have the correct values
