Answer:
Here,
A factory produced 252 televisions in 9 hour
In 1 hour it produces 252/9 televisions
= 28
so the answer is it produces 28 televisions per hour or each hour.
Answer:
117 feet squared
Step-by-step explanation:
Multiply the height (9 feet) by the width (13 feet).
9 x 13 = 117
117 feet squared
Note: squared is added when describing area (it's used as an exponent in numbers)
Answer:
x ≤ -7
Step-by-step explanation:
Symbolically, we have 11 - 3x ≥ 32
and we can solve this for x as follows:
Add 3x to both sides. We get:
11 - 3x + 3x ≥ 32 + 3x
Then 11 ≥ 32 + 3x
Reversing the order, we get 3x + 32 ≤ 11
Subtracting 32 from both sides, we get:
3x ≤ -21
Finally, dividing both sides by 3 yields:
x ≤ -7
We can solve this by looking at pairs that equal 60.
6 and 10 get to 60 when multiplied. Let's see if it fits in as a perimeter.
12+20=32
So the width and length of the room is 6 meters and 10 meters.
x+y-z+w = 10--------(1)
x+3y-4z+5w=26------(2)
x+4y-7z+7w = 37-------(3)
x+2y-3z+6w = 22--------(4)
Subtract equation (1) from (2)
x+3y-4z+5w - (x+y-z+w) = 26 - 10
2y + -3z - 4w = 16-----------------------------(5)
Subtract equation (1) from (3)
