Answer:
It can be 5 or 3
Step-by-step explanation:
let x = that number
x * (x - 8) = -15
xx - 8x + 15 = 0
xx - 3x - 5x + 15 = 0
x(x - 3) - 5(x - 3) = 0
(x - 5)(x - 3) = 0
then x = 5 or x = 3
To solve this, we’ll have to use inverse operations.
Since addition is the inverse to subtraction, we’ll add 20 to 620.
20 + 620 = 640
From there, since division is the inverse of multiplication, we’ll divide .75 by 640.
640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.
Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)
Hope this helps! :)
It is A. When you try to get 20 divided by 5 it gives you 4. 5 times 4 is 20 therefore it gives you A
So,
First, we will find the surface area of the garden in feet.
(70)(45) = 3150 square ft.
Next, to find the surface area of the garden inches, we need to recall the conversion rate between feet and inches.
1 ft. = 12 in.
So, multiply 3150 by 12.
(3150)(12) = 37,800 square in.
To find the surface area of the garden in yards, we need to recall the conversion rate between yards and feet.
1 yd. = 3 ft.
So, divide 3150 by 3.
Area of the garden in inches: 37,800 square in.
Area of the garden in feet: 3150 square ft.
Area of the garden in yards: 1050 square yd.
Answer:
70 + (-30) + 2 + (-9) + 0.3 + (-0.1) = [70 + (-30)] + [2 + (-9)] + [0.3 + (-0.1)]
