Answer:
D
Step-by-step explanation:
there are infinite solutions because if the numbers are equal that means that both sides are equal
both sides have x too
therefore x can be any value and the equation will still be true
The expression can be estimated by , so the answer would be roughly 14 here. I'm not sure where you got that '1' from.
Directly below that problem, we have the expression which can be estimated by computing which simplifies to 63. The '1' is from rounding to the nearest whole number.
Other than that, everything else looks correct on your worksheet.
Answer: 8
Step-by-step explanation:
I think it's 8 but im not so sure
The area can be found out by multiplying the length and the breadth and also by adding the boxes.
Mathematically,
(4+5+4+7)× 10
or
L×B = r + g + w + b
or
L×B = 3r + w
therefore
L×B is a multiplication expression.
Total number of boxes along the length = L= 20= 4+5+4+7
Total number of boxes along the breadth= B= 10
Total area or total number of boxes = L×B= 20×10=200
Total number of boxes= N= 200
Number of red boxes = r = 46
Number of green boxes = g = 46
Number of blue boxes = b = 46
Number of white boxes= w= 62
Mathematically,
N= r+ g + w + b
but r = g = b
therefore
N= 3r + w
N= r + g + w + b
L×B= N
or
L×B = r + g + w + b
L×B = 3r + w
A multiplication expression is one which has variables or numbers being multiplied.
