Answer:
⅖ m = 40 cm
Step-by-step explanation:
1 meter = 100 cm
1 : 100 = 2/5 : y
1 × y = 100 × 2/5
y = 40
1 pound=16ouncees
1ounce =28 grams aprox
so 5 pounds times 16=80 ounces
80 ounces times 28=2240 grams aprox
Answer:
1) 2<x<10 (the first choice)
2) 17<u><</u>x<40 (the first choice)
3) x<u><</u>-1 or x<u>></u>2 (the second choice)
Step-by-step explanation:
1) 2<x<10...this is another way of representing x<10 and x>2 in an "and" inequality. If you look at 2<x<10 from left to right, it says 2 is less than x and x is less than 10.
2) 17<u><</u>x<40...this represents x<u>></u>17 and x<40 in an "and" inequality as well. If you look at 17<u><</u>x<40, it reads 17 is less than or equal to x and x is less than 40.
3) x<u><</u>-1 or x<u>></u>2...the signs are greater than or equal to because the dots are closed on the number line. Also, this is not an "and" inequality. This is actually an "or" inequality. You can mainly tell because the lines are shaded opposite ways and do not intersect.
I hope this helped!! Good luck on your assignment and have a wonderful day :3
Answer:
(4.449, 0.449) and (-0.449, -4.449)
Step-by-step explanation:
xy = 2
y = 
Vertical asymptote → x = 0
Horizontal asymptote → y = 0
Input-output values for the equation,
x -2 -1 1 2 4
y -1 -2 2 1 0.5
Input-output values of the equation,
x - y = 4
x -2 -1 0 1 2
y -6 -5 -4 -3 -2
Solutions of the system of equations → (4.449, 0.449) and (-0.449, -4.449)
Answer:
x = -2
Step-by-step explanation:
For this problem, we must simply solve for x. To do this, we will need equation operations, and the use of the distributive property.
Let's work this line by line until we have the value for x:
3{-x + (2x + 1)} = x - 1
3*-x + 3*(2x + 1) = x - 1
-3x + 6x + 3 = x - 1
3x + 3 = x - 1
2x = -4
x = -2
Now we can check our answer for x by plugging back into the original equation and see if the left hand side is equal to the right hand side:
3{-x + (2x + 1)} = x - 1
3{-(-2) + (2(-2) + 1)} ?= (-2) - 1
3{2 + (-4 + 1)} ?= -3
3{2 + (-3)} ?= -3
3{-1} ?= -3
-3 == -3
Thus, we have found the solution for x to be equivalent to negative 2.
Cheers.
