Ellie had 80 peanuts before she ate 49 of them.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x be the number of peanuts Ellie had before she ate 49 of them.
After eating 49 peanuts, Ellie has 31 peanuts left, so we can write an equation:
x - 49 = 31
To solve for x, we add 49 to both sides of the equation:
x - 49 + 49 = 31 + 49
Simplifying, we get:
x = 80
Therefore, Ellie had 80 peanuts before she ate 49 of them.

The length of a rectangle is 5 inches less than twice its width. The perimeter of the rectangle is 26 inches. What is the width of the rectangle?
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6

a) La autopista 10 en Haradh, Arabia Saudita, tiene más de 200
km en línea recta. Un automóvil viaja por esta carretera con
velocidad constante de 120 km/h durante 200 km.?
Explicación paso a paso:
Como no dijimos qué calcular, también podemos encontrar el tiempo que tarda el automóvil en viajar por la carretera.
Velocidad = Distancia / Tiempo
Tiempo = Distancia / Velocidad
Dado
Distancia = 200 km
Velocidad = 120 km / h
Sustituir
Tiempo = 200/120
Tiempo = 20/12
Tiempo = 1,67 horas
Por tanto, el tiempo que tarda el coche en recorrer la carretera es de 1,67 horas.
Se tarda aproximadamente 1.67 horas en viajar por la autopista de Arabia Saudita.
La velocidad es la relación entre la distancia total recorrida y el tiempo total empleado. Está dado por:
Velocidad = distancia/tiempoDeje que el tiempo necesario para viajar Arabia Saudita sea t. Por eso:
120 km/h=200 km/tt = 200/120
t=1.67 horasSe tarda aproximadamente 1.67 horas en viajar por la autopista de Arabia Saudita.

Part 1: The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
Part 2: What is the rate of change in the equation from Part 1?
My Data:
Foot Length Forearm length
7 9
8 10
9 11
10 12
11 13
Rate of Change: 2
Compare the equation from Part 1 to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Part 3: Is the relation in your data a function? Why or why not? Could the equation in Part 1 represent a function? Why or why not? Explain your answer.
Answer:
The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.860 • (length of the forearm) + 3.302 If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302.

what’s the greatest common factor of 65 and 55
Answer:
We found the factors and prime factorization of 55 and 65. The biggest common factor number is the GCF number. So the greatest common factor 55 and 65 is 5.
Answer:
5
Step-by-step explanation:
Since we are asked to find the greatest common factor, our best choice would first be to find the prime factorization of [tex]$65$[/tex] and [tex]$55$[/tex].
[tex]$65 = 5\cdot13.$[/tex]
[tex]$55 = 5\cdot11$[/tex]
From this, we can conclude that the greatest common factor is [tex]\boxed{5}[/tex].

. Solve for x. Show your work: 4(x+1)= -3x-10 :)
Answer:
x = - 2
Step-by-step explanation:
Distribute
4(x + 1) = -3x - 10
4x + 4 = -3x - 10
Subtract 4 from both sides of the equation
4x + 4 = -3x - 10
4x + 4 − 4 = −3x − 10 − 4
Simplify
Subtract the numbers
4x+4−4=−3x−10−4
4 = − 3 − 1 0 − 4
Subtract the numbers again
4 = − 3 − 14
Add 3x to both sides of the equation
4 = − 3 x − 1 4
4 + 3 = − 3 − 1 4 + 3
Simplify
Combine like terms
4 + 3 = -3x-14+3x
7x =−3x−14+3x
Divide both sides of the equation by the same term
7 = − 1 4
7 /7 = -14/7
Cancel terms that are in both the numerator and denominator
7x/7 = -14/7
x = -14/7
Divide the numbers
= − 1 4 /7
= − 2

Salvador earns $13.00 per hour. If he works more than 40 hours a week
he earns time and a half. This week he worked 7 hours of overtime. How
much overtime pay did he receive?
Answer:
$136.50
Step-by-step explanation:
Time and a half = 13.00 + (13 × 1/2)
Time and a half = 13.00 + 6.50
Time and a half = $19.50
If he works 7 hours of overtime, and overtime means getting paid time and a half, we would multiply 7 hours by $19.50 to find the total amount he was paid
7 × 19.50 = 136.50
In overtime, he was paid $136.50

4. X = 7
Answer: If u divide both sides by 3 you get the value o x 2 answer: Combine terms by transporting. The equation becomes 4x -7x = -21
Step-by-step explanation: 1. 4x=7(x-3) -----> Start with the given.
2. 4x=7x-21 -----> Distribute 7 by multiplying it to the individual terms inside the parenthesis. 7(x) - 7(3) = 7x -21
3. -3x=-21 ------> From step 2, combine like terms by transposing. The equation becomes 4x - 7x = -21. Simplifying, it becomes -3x = -21
4. x = 7 -----> Divide both sides by -3, you get the value o x.

Actually Welcome to the Concept of the Statistics,
If we see here, The Andrew is working for 20 hours and his pay for 20hours is, $175
so for 1 hour, he gets = 175÷20 => $8.75 per hour
, so now after 1 year, his pay increases by $1.05 per hour, then we have to add this new amount of pay in his old amount, so that we can show that his pay is actually INCREASED, so the new pay is given as,
$8.75 + $1.05 (per hour)= $9.80
so now his total pay is given as,
E= 9.80h
Option D.) is correct

Given a central angle of 252° and an arc length of 44 ft, determine the radius.
Answer:
10ft
Step-by-step explanation:
Given parameters:
Central angle = 252°
Arc length = 44ft
Unknown:
Radius = ?
Solution:
To find the radius of the circle, let us use the expression;
Arc length = [tex]\frac{central angle}{360}[/tex] x 2πr
Insert the parameters and solve for r,
44 = [tex]\frac{252}{360}[/tex] x 2 x 3.142 x r
44 = 4.4r
r = 10ft
