A = 4.52 m²
Answer:
this equation would have one solution
Step-by-step explanation:
Because it has 2 different numbers before the variables.
First, convert both fractions into improper fractions:
-2 and 1/4= -9/4
-4 and 1/2= -9/2
Now we can find the product!
-9/4 x -9/2= 81/8
(Remember that when you multiply two negatives, the product turns positive)
And because 81/8 cannot be reduced, to find your final answer, just covert 81/8 into a mixed fraction!
81/8= 10 and 1/8
Hope this helps!
Answer:
x=9
y=2
z=1
Step-by-step explanation:
xx+yy=zyz
xx can be divided by 11
yy can be divided by 11
zyz can be divided by 11
3 digit multiples of 11
110
121
132...
121=zyz because z=1 and y=2
121-22=99
xx=99
x=9
z=1
y=2
