Have a nice day :)
Can you give me brainliest plz :)
Answer:
25/42
Step-by-step explanation:
You can get to 25/42 by finding the least common denominator, or in layman's terms, by seeing what the lowest number the two denominators can both EQUALLY go in to. in this case it's 42, as both 6 and 7 can go into 42 equally, and 42 is the lowest number that they both can go into. So after you find the least common denominator, you make that the denominator of both fractions, and multiply the two numerators by however many times you had to multiply the denominators by. for example, to get 7 to 42, you need to multiply it by 6, so you would then multiply the numerator, in this case it's 3, 6 times, netting you 18. you do the same thing with the other fraction, since the numerators 1, you multiply it by 7, since you had to multiply 6 by 7 to get 42. this leaves you with 18/42 + 7/42, which you can now normally add together to get 25/42, and since it can't be reduced, it stays this way. Hope this helps :)
why does -5/10 equal 5/-10 ? explain..
Answer:
-5/10 equals to 5/-10 because even though the numerator/denominator is negative, when you simplify -5/10 or 5/-10, it give you -1/2 and 1/-2.

what value of x makes the following equation true 4+3x=160
Answer:
x=52
Step-by-step explanation:
160=4+3x
Subtract 4 from both sides
156=3x
Divide 3 from both sides
x=52
-1/2 = m -7/4
solve for m
Answer:
[tex]\boxed {m = \frac{5}{4}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]m[/tex]:
[tex]-\frac{1}{2} = m - \frac{7}{4}[/tex]
-Switch sides:
[tex]m - \frac{7}{4} = -\frac{1}{2}[/tex]
-Add both sides by [tex]\frac{7}{4}[/tex] and the least common multiple of both [tex]2[/tex] and [tex]4[/tex] is [tex]4[/tex]. So, convert [tex]-\frac{1}{2}[/tex] to a fraction with denominator [tex]4[/tex]:
[tex]m - \frac{7}{4} + \frac{7}{4} = -\frac{1}{2} + \frac{7}{4}[/tex]
[tex]m = -\frac{2}{4} + \frac{7}{4}[/tex]
-Since both [tex]-\frac{2}{4}[/tex] and [tex]\frac{7}{4}[/tex] have the same denominator, then you would add the numerators:
[tex]m = \frac{-2 + 7}{4}[/tex]
[tex]\boxed {m = \frac{5}{4}}[/tex]
Therefore, the value of [tex]m[/tex] is [tex]\frac{5}{4}[/tex].
A number and its additive inverse, or opposite are considered what
additive inverse. and additive inverse of a number “a” is the number that, when added to “a”, yields 0. this number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

What is the equation of the line that is parallel to the
given line and passes through the point (-2, 2)?
O y=1/5x+4
Oy= 1/5x+12/5
O y = -5x + 4
O y=-5x +12/5
The equation of the parallel line that passes through the point (-2, 2) is y= (1/5) x + (12/5)
What is meant by line's slope?The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run." Choose two points on the line and calculate their coordinates. Determine the difference in y-coordinates between these two points. Determine the difference in x-coordinates between these two points. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).There are four types of slopes: negative, positive, zero, and undefined. as x grows The slope of a line can also be interpreted as the "average rate of change."Therefore,
The slopes of the two lines will be the same because it runs parallel to the line predicted by the equation.
The slope of the line is 1/5,
We know that the line is y= (1/5) x + c.
We can now find the y-intercept using the given point (-2,2).
[tex]$&\Rightarrow y=m x+c \\[/tex]
[tex]&y^2=\frac{1}{5}(-2)+c \\[/tex]
[tex]&\Rightarrow^2=\frac{-2}{5}+c \\[/tex]
[tex]&\Rightarrow c=2+\frac{2}{5}=\frac{10+2}{5}=\frac{12}{5} \\[/tex]
[tex]&\Rightarrow c=\frac{12}{5}[/tex]
Hence, The line's final equation will be [tex]y=\frac{1}{5} x+\frac{12}{5}[/tex]

Find the value of x so that the function has the given value.
k(x)=6x−1/2; k(x)=18
Answer:
x = [tex]\frac{37}{12}[/tex]
Step-by-step explanation:
Given k(x) = 6x - [tex]\frac{1}{2}[/tex] and k(x) = 18, the equate the right sides, that is
6x - [tex]\frac{1}{2}[/tex] = 18 ( multiply through by 2 to clear the fraction )
12x - 1 = 36 ( add 1 to both sides )
12x = 37 ( divide both sides by 12 )
x = [tex]\frac{37}{12}[/tex]

Answer:
The pool is 400 square meters
Step-by-step explanation:
To figure out the are of a slanted shape such as this, we must turn it into a shape that is non-slanted, like a rectangle or square (which is a type of rectangle). For this parallelogram, we can separate the shape into three parts: the two slanted bits on the outside, and a rectangle (7*2) in the middle (or on the inside).
We can see that each slanted part can take up half of two squares, and therefore one square. From here on out, we can do this one of two ways:
1. Figure out the area of the inside rectangle, then add the two slanted parts/two squares separately
OR
2. Since each slanted area equals one square, or since each is half of two square, we can add both sides together (for 1/2 + 1/2 = 1, or in this case, 1 +1 = 2), to make a full or complete rectangle, before figuring out the area of the shape as a whole (8*2).
8*2 = 16
Each square is 1 cm squared, which is in proportion to 25 meters squared (each cm is 5 meters (1:5), so the square, which is 1 cm by 1 cm, is proportionate to 5 meters by 5 meters).
16*25 = 400
The pool is therefore 400 square meters.
