Answer:
the total number of blocks is 69
Step-by-step explanation:
the way you can find this is by counting all the outside blocks on the closest side (23) and multiplying it by the the width of the blocks on the right side (3)
Answer:
C- all numbers less than 13.
Why these are incorrect:
A- If it was "less than or equal to" the sign would have to be "≤"
B- If it was 'greater than or equal to" the sign would have to be "≥"
D- If it was "greater than" the sign would have to be ">"
Answer:
x and y do not show direct variation.
Step-by-step explanation:
The formula for direct variation is
y = kx Divide each side by y
k = y/x
k should have the same value for every point except, of course, (0,0)
For the first point,
k = 2/(-1) = -2
For the third point,
k = 2/1 = 2
The values of k are different, so x and y <em>do not</em> show direct variation.
Answer: 28-6x
This is the same as -6x+28
===============================
To get that answer, you multiply each term inside the parenthesis by the outer term 2
14 * 2 = 28
-3x * 2 = -6x
So,
(14-3x)*2 = 14*2 - 3x*2 = 28-6x
----------
The distribution rule says
a(b-c) = ab-ac
which is the same as saying
(b-c)a = ba-ca
We can flip things around because we can multiply in any order.
