) Erin owes her mom $25. She borrows another $15 from her mom. What is her balance now, that she owes her mom?
Answer:
$40
Step-by-step explanation:
she owed $25 at first then she borrowed $15 so now she owed her $40.
25+15=40
Answer:
40
Step-by-step explanation:
Once you add 25 and 15
5+5=10
so you put the 1 over the 2 than add 2+1 and add 1 from the 10.
So the answer is 40
Okay guys please help and explain it accurately and solve please so I can understand it. This is for 100 points!
-6a + 10 = -27
-6a + 10 = -27
First step: subtract 10 from both sides:
-6a = -37
Now divide both sides by -6:
A = -37/-6
Simplify:
A = 37/6
Answer:
a = 37/6
Step-by-step explanation:
-6a +10 = -27
Subtract 10 from each side using the subtraction property of equality
-6a+10-10 = -27-10
-6a = -37
Divide each side by -6 using the division property of equality
-6a/-6 = -37/-6
a = 37/6
Question 12
evaluate
Answer:
-12.8
Step-by-step explanation:
Replace the letters with the respective values ( a = 4, b = 2, c = 3).
So (-3a+4b)^3 would become (-3 (4) + 4 (2))^3 = (-12 + 8)^3 = -4^3 = -64
And the bottom part (2c -1) would become (2 (3) - 1) = 6-1 = 5
So the final result would be -64 / 5 which is approximately -12,8

Show your work and solve for x and y.
3x + y = 8
2x + 4y = 12
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
Answer:
[tex]\huge\boxed{\sf Solution Set = \{(2,2)\}}[/tex]
Step-by-step explanation:
3x + y = 8 ----------------------(1)
2x + 4y = 12 -------------------(2)
Multiply Eq. (1) by 4
4(3x+y) = 8*4
12x + 4y = 32 -----------------(3)
Subtract Eq. (3) from (2)
2x + 4y - (12x + 4y) = 12 - 32
2x + 4y - 12x - 4y = -20
2x - 12x = -20
-10x = -20
Divide both sides by -10
x = 2
Put x = 2 in Eq. (1)
3(2) + y = 8
6 + y = 8
Subtract 6 to both sides
y = 8 - 6
y = 2
Solution Set = {(x,y)} = {(2,2)}

If 8(x - 2y) = 16x, then what is x in terms of y?
Answer: y = -1/2x
8(x - 2y) = 16x
8x -16y = 16x
-16y = 16x-8x
-16y = 8x
-16y/-16= 8x/-16
y = -1/2x

30. f(x) = |x|; reflection in the y-axis followed by a
translation 3 units right
Answer:
[tex]g(x) = |x-3|[/tex]
Step-by-step explanation:
We are given the parent function:
[tex]f(x) = |x|[/tex]
And we want to find the equation after a reflection in the y-axis followed by a translation of three units right.
To reflect a function over the y-axis, we multiply the input by a negative. That is:
[tex]\displaystyle f(x) \rightarrow f(-x)[/tex]
In other words, a reflection over the y-axis will be given by:
[tex]f(-x) = |-x|[/tex]
To shift horzontally, we add if we are moving leftwards or subtract if we are moving rightwards. That is:
[tex]f(x) \rightarrow f(x-k)[/tex]
Where k is the horizontal translation.
Since we are translating three units rightwards, k = 3. Hence:
[tex]\displaystyle f(-(x-3)) = |-(x-3)|[/tex]
Recall that |ab| = |a||b|. Hence:
[tex]\displaystyle f(-(x-3)) = |-(x-3)| = |-1||(x-3)| = |x-3|[/tex]
Hence, f reflected over the y-axis followed by a translation of three units right is given by:
[tex]g(x) = |x-3|[/tex]

Answer:
Step-by-step explanation:
Perimeter = 2W + 2L
160 = 2W + 2L
width = 16 feet less than length
W = L - 16 ------------(I)
Finding the dimensions of the court:
2W + 2L = 160
2*(L-16) + 2L = 160 {from (I) }
2*L - 2*16 + 2L = 160 {Distributive property}
2L - 32 + 2L = 160
2L + 2L - 32 = 160 {Combine like terms}
4L - 32 = 160 {Add 32 to both sides}
4L = 160 +32
4L = 192 {Divide both sides by 4}
L = 192/4
L = 48
W = 48 - 16
W = 32
