5x + 3y = 22
y = 2x
Substitute y=2x into the first equation
5x + 3(2x) = 22
5x + 6x = 22
11x = 22
x = 2
Hope that helps :)
Answer:
A2: 4*4*4 = 64 cm³; 6*6*6 = 216 cm³; etc...
B2: 7*4.5*4 = 126 cm³; 10.5*6*2 = 126 cm³; etc...
Step-by-step explanation:
So in A2 you have cubes, so l=b=h, and only one has to be given, called the "length of side".
In B2 they are different, hence there are 3 rows with l, b and h. But still you multiply them l x b x h
Answer:
B
Step-by-step explanation:
This is one of the photos I used to answer, I’m going to send the second one
The slope would be -1 since it’s the coefficient of -x
