Answer:
30x+25y+20z=138030x+15y+5z=89010x+10y+5z=450Step-by-step explanation:
in this problem we are expected to formulate the constraints
let chairs, loungers and footstools be x, y and z respectively
1. For wood we have
30x+25y+20z=1380
2 . For fabric we have
30x+15y+5z=890
. For stuffing we have
10x+10y+5z=450
therefore the three equation are
30x+25y+20z=1380
30x+15y+5z=890
10x+10y+5z=450

What is the slope and y intercept of the
following equation? y = -5x - 2
Answer:
slope: -5 y intercept: (0,-2)
Step-by-step explanation:
y=mx+b
slope: m y int: b
Answer:
y intercept is -2 and slope is -5
Step-by-step explanation:
The equation is in slope-intercept form or y=mx+b.
This is awsome cause its super easy to find the slope and y intercept if you know exactly where to look.
so if try looking at the formula y = m x + b as y = (slope) x + (intercept)
if you subtracting b that just means your y intercept is going to be negative
and its the same with your m, if its negative your slope is gonna be negative.

. 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

Answer: True
Step-by-step explanation:
Answer:
true
Step-by-step explanation:
Solve this equation: –3(x – 14) + 9x = 6x + 42
Solving this equation results in the statement 0 = 0. Because this is a true statement, the equation has a unique solution.
Solving this equation results in the statement 6 = 0. Because this is a false statement, the equation has infinitely many solutions.
Solving this equation results in the statement 0 = 0. Because this is a true statement, the equation has infinitely many solutions.

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

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.

Answer:
it can grow .125 inches an hour
Step-by-step explanation:
if thats not what u were looking for commet it and ill try to help more
Answer:
.125 inches per hour
Step-by-step explanation:
you divide .25 by 24, since there are 24 hours in a day and get .0104.... and then you multiply that by 12, since there are 12 inches in a foot and get .125 inches per hour.

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

Explain how to find 5 - 7 by using counters . (Show your work)
Answer:
-3
Step-by-step explanation:
We have to find the difference:
We start with 5 yellow counters
Since we have to subtract more yellow counters than we have (5 instead of 8), we add 3 zero-pairs:
We subtract the 8 yellow counters:
We are left with 3 red counters, which means the result is -3
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
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].
