Lin read for X minutes and Elena read for 5/8 more than that. Write an expression for the number of minutes elna read.only use decimals in your expression
Elena read X + 0.625 minutes.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
Lin read for X minutes and Elena read for 5/8 more than that.
That means,
the number of minutes Elena read,
= number of minutes Lin read + 5/8
= X + 5/8
= X + 0.625
Therefore, X + 0.625 is the required expression.

–7 – 3x + 5 – 6x
Answer:
-9x-2
Step-by-step explanation:
-7-3x+5-6x
=(-3x-6x) + (-7+5)
=(-9x)+(-2)
= -9x - 2
First, use the associative property of addition to reorder the terms in parentheses. Then, combine like terms and you will get your simplified answer of -9x - 2. Hope this helps!
The frequency vibrations for a certain guitar string When is blood can be determined by the equation below, Where F is the number of vibration per second and T is measured in pounds.If the frequency of the vibrations is 600 vibrations per second, How many pounds of tantrums was used to plug the string? F = 200sqrt(T)
Answer:
9 poundsStep-by-step explanation:
Given the frequency vibrations for a certain guitar string modeled by the equation
F = 200√T where:
T is amount of tantrums in pounds
If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:
600 = 200√T
Divide both sides by 200
600/200 = 200√T /200
3 = √T
Square both sides
3² = (√T)²
9 = T
T = 9
Hence 9 pounds of tantrum was used to plug the string

HAIR BUNDLES: B'UNIQUE Hair Salon owner buys seven hundred bags of a brand of synthetic hair bundles and four hundred bags of a brand of natural hair bundles for her Forestville and Largo locations to get ready to welcome back their clients for her reopening this weekend. The Forestville location receives three hundred bags of synthetic hair bundles and two hundred and fifty bags of natural hair bundles for a total retail value of twenty-three thousand, six hundred dollars. The Largo location receives four hundred bags of a brand of synthetic hair bundles and one hundred and fifty bags of a brand of natural hair bundles for a total retail value of twenty-four thousand, five hundred dollars. What is the retail value of one bag of a synthetic hair bundle and one bag of a natural hair bundle. In your answer, write a system of equations of how you would determine your answer. Provide evidence of your calculations and answer your result in a complete sentence.
Answer:
The retail value of one bag of one bag of a synthetic hair bundle is $47 and the retail value of a bag of natural hair bundle is $38
Step-by-step explanation:
The given information are;
The number of bags of synthetic hair bundles the owner buys = 700
The number of bags of natural hair bundles the owner buys = 400
The number of synthetic hair bundles the Forestville location receives = 300
The number of natural hair bundles the Forestville location receives = 250
The total retail value of the hair bundles the Forestville location receives = $23,600
The number of synthetic hair bundles the Largo location receives = 400
The number of natural hair bundles the Forestville location receives = 150
The total retail value of the hair bundles the Largo location receives = $24,500
Let the price of a bag of synthetic hair bundle = x
Let the price of a bag of natural hair bundle = y
∴ 300·x + 250·y = $23,600...(1)
400·x + 150·y = $24,500...(2)
Making y the subject of the formula in both equations gives;
For equation (1)
y = 23,600/250 - 300/250·x = 94.4 - 1.2·x
y = 94.4 - 1.2·x
For equation (2)
400·x + 150·y = 24,500
y = 24,500/150 - 400/150·x = 490/3 - 8/3·x
y = 490/3 - 8/3·x
Finding the common solution gives;
490/3 - 8/3·x = 94.4 - 1.2·x
490/3 - 94.4 = 8/3·x - 1.2·x
1034/15 = 22/15·x
x = 1034/15/(22/15) = 47
x = 47
∴ The price of a bag of synthetic hair bundle = x = $47
The price of a bag of synthetic hair bundle = $47
y = 490/3 - 8/3·x = 490/3 - 8/3 × 47 = 38
y = 38
The price of a bag of natural hair bundle = y = $38
The price of a bag of natural hair bundle = $38.
Therefore, the retail value of one bag of one bag of a synthetic hair bundle is $47 and the retail value of a bag of natural hair bundle is $38.

so D is the answer
Answer:
[tex]\boxed {x = -2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]9 - 4x = 17[/tex]
-Subtract both sides by [tex]9[/tex]:
[tex]9 - 9 - 4x = 17 - 9[/tex]
[tex]-4x = 8[/tex]
-Divide both sides by [tex]4[/tex]:
[tex]\frac{-4x}{-4} = \frac{8}{-4}[/tex]
[tex]\boxed {x = -2}[/tex]
Therefore, value of [tex]x[/tex] is [tex]-2[/tex].

complete the table for values for y=x^2-x-2
Answer:
x -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2
Step-by-step explanation:
The given equation is y=x²-x-2.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
We need to find the y values of the give x values.
Given that, x = -3 -2 -1 0 1 2 3
When x = -3, y = (-3)²-(-3)-2
= 9+3-2 = 10
When x = -2, y = (-2)²-(-2)-2
= 4+2-2
= 4
When x = -1, y = (-1)²-(-1)-2
= 1+1-2
= 0
When x = 0, y = 0²-0-2
= -2
When x = 1, y = 1²-1-2
= -2
When x = 2, y = 2²-2-2
= 0
When x = 3, y = 3²-3-2
= 4
So, the complete table is
х -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2 0 4
There, the y values of the given x values in the given equation is y = 10, 4, 0, -2, -2, 0, 4.
