Answer:
(a)
Given expression: 49% of 162
we can write 49% as
then;
Therefore, the estimate of the given expression is, 79.38.
(b)
Using mental math to calculate 49% of 162.
Mental math is used as a way to calculate an estimate quickly.
We can write 49% = 50% -1%
(50%-1%) of 162 = 50% of 162 -1% of 162
so,
50% of 162 =
and
1% of 162 =
Now, subtract these we get;
81 - 1.62 = 79.38
Therefore, by using mental math 49% of 162 is, 79.38

Answer:
Hi did I get it wrong last time.If I did sorry!! :(
Step-by-step explanation:
but the answer is 10 mark as Brainlist if you can
Y = -x+1 is in the form y=mx+b. To compare their slopes, let's get x+y=1 into y=mx+b form.
x+y=1
-x -x
-----------
y=-x +1
Both functions have a slope of -1, and both have the y-intercept of 1.
Since they are the same line, they will be on top of each other and have infinitely many solutions.
