Multiple (5x+y= 28) by 6 giving you 30x +6y =168 and then you would add the two equations together, giving you 38x = 152, divide both sides by 38, giving you 4. after this, you would sub x=4 into one of the equations (i’m using the 5x+ y =28) which would give me 20 + y = 28, subtract 20 by both sides, giving you y= 8. so your answer is (4,8)
Answer:
665
Step-by-step explanation:
The tool bench which has the shape of a rectangle, a 4-sided shape with lengths and width.
The area of a rectangle A is given by the formula;
A = L × B
Where L is the length, B is the width
Given the bench is 35 inches long and 19 Inches wide
L = 35 inches, B = 19 inches
A = 35 × 19 = 665 square inches
The tool bench will cover 665 square inches of the basement floor .
Knowing it has to be perpendicular, the slope of the new line has to be -2.
y = -2x + b
Plug the coordinate pair into the equation.
10 = -2(7) + b
10 = -14 + b
24 = b
So the final equation for the line is...
y = -2x + 24
Answer:
the answer is 0
Step-by-step explanation:
a negative plus a positive is a positive
Answer:
8.3%
Step-by-step explanation:
In a simple way, we know that both are independent events, therefore, in the case of the dice it has 6 faces, therefore the probability of 3 coming out is 1/6 and in the case of the coin it only has two options, which means that the probability is 1/2.
Now the final probability is the multiplication of these events, that is:
1/6 * 1/2 = 0.083
Which means that the probability of these two events happening is 8.3%
