Answer:
Sales= $750Step-by-step explanation:
let sale be x
and his salary be y
y=300+0.4x----------1 the old equation
y=450+0.2x----------2 the new equation
for his salary to be the same
equation 1 and 2 must be equal hence
300+0.4x=450+0.2x
solving for x we have
300-450+0.4x-0.2x=0
-150+0.2x=0
0.2x=150
x=150/0.2
x=$750

x + y = -10 in slope intercept form
Step-by-step explanation:
Hey there!
Given;
x+y= -10
We know that slope intercept equation form of straight line is; y = mx+c.
So, let's try to convert it into that form.
Shift"X" in Right side.
y = -x-10
Therefore, y = -x-10.

2(x+3)=x-4
Anyone know the answer please lol
Answer:
The Answer is -10.mark this answer as BRAINLIEST answer. And I hoped this helpful for you....
Thank you ☺️☺️
Lets solve your equation step-by-step
2(x+3)=x-4
Step 1 :Simplify both sides of the equation
2(x+3)=x-4
(2)(x)+(2)(3) =x+-4 (distribute)
2x+6=x+-4
2x+6=x-4
Step 2: Subtract x from both sides
2x+6-x=x-4-x
x+6=-4
Step 3: Subtract 6 from both sides
x+6-6=-4-6
Answer: x=-10

I need help with angles
Answer:
The value of x is 8
The measure of angle A is 42 degrees
A and B are consecutive interior angles
Step-by-step explanation:
Since A and B are consecutive interior angles you combine both equations and have it equal to 180
16x+10+5x+2=180
21x+12=180
21x=168
x=8
Plug 8 into the equation across from A
16(8) +10
128+10
138 degrees
Since angle A is supplementary you do 180-138= 42 degrees

Answer:
(-4,3)
Step-by-step explanation:
Answer:
P = -4, 3
Step-by-step explanation:
Locate the x-axis (horizontal) location of point P, starting from zero
Point P's x-axis = -4
Now locate the y-axis (vertical) location of point P, starting from zero
Point P's y-axis = 3
Combine the two axes in a coordinate equation.
Point P = (-4, 3)
Note that zero is located at the intersection of the two axes.

$6.89 per pound for salmon OR $3.50 for 8 ounces (half a pound) of salmon
Answer: 6.89 per pound (assuming you meant which is the better deal)
Step-by-step explanation:
There are 16 ounces in a pound so you can multiply, 3.5 x 2 (since it is 3.5 for 8 ounces) to get 7. Therefore $6.89 for a pound is cheaper.

Guadalupe fue a la mercería a comprar 15.5 m de encaje blanco que necesita para la clase de costura. Si cada metro cuesta $5.60, ¿cuánto pagó por todo el encaje que necesita?
También pidió 4.75 m de cinta azul que le encargó su mamá. Si el metro cuesta $8.80 y su mamá le dio $40.00, ¿le alcanzará el dinero para comprarla?
¿Le falta o le sobra dinero? ¿Cuánto?
Answer:
a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.
b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.
Step-by-step explanation:
a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado ([tex]n[/tex]), medido en metros, y el coste unitario ([tex]c[/tex]), medido en pesos por metro:
[tex]C = c\cdot n[/tex] (Eq. 1)
Si conocemos que [tex]c = 5.60\,\frac{\$}{m}[/tex] y [tex]n = 15.5\,m[/tex], entonces tenemos que:
[tex]C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)[/tex]
[tex]C = \$ \,86.8[/tex]
Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.
b) El coste total de la cinta azul es: ([tex]c = 8.80\,\frac{\$}{m}[/tex], [tex]n = 4.75\,m[/tex])
[tex]C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)[/tex]
[tex]C = \$\,41.8[/tex]
Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Step-by-step explanation:
Billy's Boat Rental Company charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Lisa's Boat Rental Company does not charge a yearly fee, but charges $14.75 every time a member rents a boat. How many times does a person have to rent a boat for the cost to be the same amount at both rental companies?
Step-by-step explanation:
we can proceed to model the cost of Billy's Boat Rental Company
let y be the cost
let x be the number of rentals
y=105+9.5x----1
Also, the cost of Billy's Boat Rental Company
y=14.75------2
the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"
we have to equate the two cost and solve for x
105+9.5x=14.75
105-14.75+9.5x=0
90.25+9.5x=0
9.5x=-90.25
divide both sides by 9.5 we have
x=-90.25/9.5
x=9.5
Approximately 10 times
