From the picture we can see that angles Z and X are the same because they are oposite angles of parallelogram and rule for it is that oposite angles are the same.
so we can write that equations for determining their size are the same
7x + 61 = 9x + 47
Now we just solve for x.
2x = 14
x = 7
If we implement this in formula for Z we find:
Z = 7*7 + 61 = 110
we implement value of x in the lenght of WY as well
WY = 84 - x = 84 - 7 = 77
Answer is C
Answer:5464
Step-by-step explanation:
Let
x---------> represents Martin's sister's age
y--------> represents Martin's age
we know that
--------> equation
--------> equation
Substitute equation in equation
therefore
<u>the answer is</u>
Part a) An inequality that can be used to represent this situation is
or
Part b) the oldest age Martin's sister can be is years old
Answer:
see the procedure
Step-by-step explanation:
we know that
so
The value of digit 8 in 1.8 is 0.8
The value of digit 8 in 486 is 80
Divide the numbers
80/0.8=100
therefore
The value of the digit 8 in 486 is 100 times greater than the value of digit 8 in 1.8
or
The value of the digit 8 in 1.8 is 100 times less than the value of digit 8 in 486
