Step-by-step explanation:
Hey ..but there is nothing from which question can be equated ..
like if they are equal to zero..
or
(4x+45)=(5x-18)
i am giving answer for both scenarios
(4x+45)=0
4x=-45
x=-45/4
x=(-11.25)
(5x-18)=0
5x=18
x=18/5
x=3.6
Incase if they both are equal to each other...
(4x+45)=(5x-18)
(45+18)=(5x-4x)
63=x
x=63

Answer:
B ($905)
Step-by-step explanation:
Plug in $17 for the h value in the equation, and you get this:
c = 50 (17) + 55
c = 850 + 55
c = 905
So the answer is $905 for 17 hours of work (plus the service fee)

What is the equation of the line that has a slope of 1/3 and goes through the point (6,−2)?
A. y = 1/3x − 4
B. y = 1/3x + 4
C. y = 1/3x − 8
D. y = 1/3x
Answer: A) y = 1/3x − 4
Step-by-step explanation:
Find the Equation Using Point-Slope Formula
slope: 1/3
point: (6, −2)
Use the slope 1 and a given point (6, −2) to substitute for [tex]x_1[/tex] and [tex]y_1[/tex] in the point-slope form
y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex]), which is derived from the slope equation m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
y − (−2) = 1/3 ⋅ (x − (6))
Simplify the equation and keep it in point-slope form.
y + 2 = 1/3 ⋅ (x − 6)
Solve for y.
1/3 ⋅ (x − 6).
Apply the distributive property.
y + 2 = 1 /3 x + 1 /3 ⋅ − 6
Combine 1/3 and x.
y + 2 = x/3 +1/3 ⋅ −6
Cancel the common factor of 3.
y + 2 = x /3 − 2
Move all terms not containing y to the right side of the equation.
Subtract 2 from both sides of the equation.
y = x/3 − 2 − 2
Subtract 2 from −2. x
y = x/3 − 4
Reorder terms.
y = 1/3x − 4
List the equation in different forms.
Slope-intercept form:
y = 1/3x − 4
Point-slope form:
y + 2 = 1/3 ⋅ (x − 6)

Answer:
x=5
Step-by-step explanation:
According to SSS, RPS and RPQ should be similar angles. Since the length RP is the same, then RQP and RSP should be similar too. Therefore PRS and PRQ should be similar too. Since QP and RS are the same (7) then QR and PS needs to be same in length too.

Find the slope of this Linear Function.
Answer:
The slope is 2/3 and the y intercept is -1
Step-by-step explanation:
you find the y-intercept (where the line passes through the y-axis) which is -1 and you go straight up 2 spots and then you go over 3 spots. Slope is rise over run. You could also use the slope formula y2-y1/x2-x1. I hope this made sense.
when 2(3/5 x + 2/3 y - 1/4 x -1 1/2 y + 3 )is simplified, what is the resulting expression?
Answer:
Simplifying the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]
Step-by-step explanation:
We need to simplify the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]
First we will solve terms inside the bracket
[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]
Converting mixed fraction [tex]1\frac{1}{2} y[/tex] into improper fraction, we get: [tex]\frac{3}{2}y[/tex]
Replacing the term:
[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-\frac{3}{2}y +3)[/tex]
Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket
[tex]2(\frac{3}{5}x\times60+\frac{2}{3}y\times60-\frac{1}{4}x\times60-\frac{3}{2}y\times60 +3\times60)\\2(3x\times12+2y\times20-1x\times15-3x\times30-3\times60)\\2(36x+40y-15x-90y-180)[/tex]
Now, combine like terms
[tex]2(36x-15x-90y+40y-180)\\2(21x-50y-180)[/tex]
Now, multiply all terms with 2
[tex]42x-100y-360[/tex]
So, Simplifying the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]

Identify the perimeter and area of a square with diagonal length 24in. Give your answer in simplest radical form!!!
242‾√ in; 288 in2
482‾√ in; 288 in2
242‾√ in; 144 in2
482‾√ in; 144 in2
Answer:
Perimeter: [tex]48\sqrt{2} \: \mathrm{inches}[/tex]
Area: [tex]288\mathrm \: \mathrm{square \: inches}[/tex]
Step-by-step explanation:
If the diagonal of the square is 24 inches, the side length of the square is [tex]12\sqrt{2}[/tex] inches ([tex]2x^2=24^2[/tex]). The perimeter of this square is then [tex]4 \cdot 12\sqrt{2}=\fbox{$48\sqrt{2}\: \mathrm{in}$}[/tex] and the area [tex](12\sqrt{2})^2=\fbox{$288\: \mathrm{in^2}$}[/tex].
The area of the square is 288 in.² and the perimeter is 48√2 in.
Given to us,
Diagonal of the square = 24 in.
We know that for a square,
[tex]\bold{(Diagonal)^2 = 2\times (side)^2}[/tex]
substituting the values,
[tex]{(Diagonal)^2 = 2\times (side)^2}\\24^2 = 2\times (side)^2}\\side = 12\sqrt {2}[/tex]
Also, the area of a square is given by (side)², and, perimeter by (4 x side).
[tex]\bold{Area = (12\sqrt2)^2 = 288 in.^2}[/tex]
[tex]\bold{Perimeter= (4\times 12\sqrt2) = 48\sqrt 2 in.}[/tex]
Hence, the area of the square is 288 in.² and the perimeter is 48√2 in.

The sum of 5 times one number, x, and 4 times a second number, y, is 87. If the sum of the two numbers is 20, find the two numbers. Pls hurry need it before schools is over
(hint will mark brainiest)
Step-by-step explanation:
We have 5x + 4y = 87 and x + y = 20.
=> 5x + 4y = 87 and 4x + 4y = 80.
5x + 4y = 87
- (4x + 4y = 80)
=> x = 7
Therefore (7) + y = 20, y = 13.
The answers are x = 7 and y = 13.

robert gets a loan from his bank.
he agrees to borrow £6000 at a fixed annual simple interest rate of 7%.
he also agrees to pay the loan back over a 10 year period.
how much money in total will he have paid back at the end of 10 years?
Answer:
the total amount that should be paid back at the end of 10 years is £10,200
Step-by-step explanation:
The total amount that should be paid back at the end of 10 years is shown below:
= Borrowed amount + simple interest
= £6000 + (£6000 × 0.07 × 10)
= £6000 + £4,200
= £10,200
Hence, the total amount that should be paid back at the end of 10 years is £10,200
Which property best describes the congruence statement below?
ДАВС = ДАВС
A. Symmetric property
OB. Reflexive property
OC. Commutative property
O O O
D. Transitive property
Answer:
I think B.Reflexive property
The property best describes the congruence statement is
Symmetric property.
What is Congruence?Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal.
We know,
The Symmetric Property states that for all real numbers
if x = y then y=x
and, Transitive Property
The Transitive Property states that for all real numbers
if x = y and y = z then z=x.
and, Reflexive Property
for any x, x = x.
Here, the property used is Symmetric.

An ounce of almonds costs $1.40. If Joey buys 2.4 ounces of almonds, how much will he have to pay?
Answer:
Joey will pay $3.36 for 2.4 ounces of almonds.
Step-by-step explanation:
Given that:
Cost of almonds = $1.40 per ounces
Number of ounces bought by Joey = 2.4 ounces
Cost of 2.4 ounces = Ounces of almond * Cost per ounce of almond
Cost of 2.4 ounces = 2.4 * 1.40
Cost of 2.4 ounces = $3.36
Hence,
Joey will pay $3.36 for 2.4 ounces of almonds.
