5 the answer I took the test
Answer:
L=93
Step-by-step explanation:
Perimeter of a rectangle is 2(L+W)
So 2(L+83)=352
L+83=176
L=93
Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
It is 39
Because you have to count the little dots all the way till it is around the most age.
