7x + 1 + 4x - 3 = 42
11x - 2 = 42
add 2 to both sides
11x = 44
divide both sides by 11
x = 4

1. Simplify by using the Distributive Property.
4(4f - 29)
Answer:
[tex]\huge\boxed{\boxed{\bf{16f-116}}}[/tex]
Step-by-step explanation:
Hello.
Do you remember what the Distributive Property states? If you don't, please don't worry :)
The Distributive Property states that
[tex]\huge\boxed{a(b+c)=ab+ac}[/tex]
Now, let's simplify our expression ;)
4(4f-29)
4 times 4f and 4 times -29:
4×4f=16f
16f- (4×(-29)
16f-116
And we're done!
I hope it helps & have an outstanding day!

Un grupo de 14 mujeres y 16 hombres
formará parejas de trabajo. ¿cuántas
parejas se pueden formar?
Responder:
14 parejas
Explicación paso a paso:
Una pareja es la combinación de un hombre y una mujer.
Dado que la cantidad de hombres reemplaza a la de mujeres en 2, esto significa que podemos emparejar a todas las mujeres con 14 hombres (excluyendo 2 hombres)
Promedio = (14 + 16) / 2
Promedio = 30/2
Promedio = 15
Como no podemos para un número impar de parejas sino pares, la cantidad de parejas que se pueden formar será:
No de parejas = promedio - 1
No de parejas = 15-1
No de parejas formadas = 14
Usando el concepto de proporción, tiene-se que 15 parejas se pueden formar.
-------------------------
Para solucionar esta pregunta, usa-se proporciones, a partir de una regla de tres.Una pareja es formada por 2 personas.En todo, tiene-se 14 - 16 = 30 personas. Quantas parejas?La regla de tres es:
1 pareja - 2 personas
x parejas - 30 personas
Aplicando multiplicacción cruzada:
[tex]2x = 30[/tex]
[tex]x = \frac{30}{2}[/tex]
[tex]x = 15[/tex]
Se pueden formar 15 parejas.

She uses 18 square inches of paper for each card How many square feet of paper does she need to make 150 cards
Answer:
225
Step-by-step explanation:
Well, we already know how many square inches each card is. 18. All we need to do is multiply that number by 150 because we need to make 150 cards. So:
18 x 150 = 2,700inches.
Now all we need to do is divide the number of inches by the amount each foot is. Each foot is 12 inches. So:
2,700 ÷ 12 = 225.
225 is your answer.
Hope this helps and have a nice day!

What are the intercepts of the linear function shown?
A) x-intercept is -2 and y-intercept is -2
B) x- intercept is -2 and y-intercept is 4
C) x-intercept is 2 and y-intercept is 4
D) x- intercept is 2 and y-intercept is -4
Look at the image!!!!
Answer:
(see explanation below)
Step-by-step explanation:
The x-intercept is where the line intersects with the x-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the x-axis at (-2, 0). Therefore, the x-intercept is -2.
The y-intercept is where the line intersects with the y-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the y-axis at (0, 4). Therefore, the y-intercept (also represented by the variable b) is 4.

.3333333333 is equivalent to
which fraction: 3/33 or 3/1 or
33/33 or 1/3
Answer:
1/3
Step-by-step explanation:
If you times 1/3 by 3, you will end up with one whole (1).
If you times .3333333... by 3, you will end up with a number that is pretty close to "1."
3/33 equals 0.090909... or 1/11, so this answer is not right.
3/1 equals 3 while 33/33 equals 1.

Ox=11
Answer:
[tex] \huge \boxed{x = - 1}[/tex]
Step-by-step explanation:
[tex] \frac{2x - 10}{4} = 3x \\ [/tex]
Multiply through by 4 to eliminate the fraction
That's
[tex]4 \times \frac{2x - 10}{4} = 4(3x) \\ 2x - 10 = 12x[/tex]
Subtract 12x from both sides of the equation
[tex]2x - 12x - 10 = 0 \\ - 10x - 10 = 0 \\ - 10x = 10[/tex]
Divide both sides by - 10
[tex] \frac{ - 10x}{ - 10} = \frac{10}{ - 10} \\ [/tex]
We have the final answer as

Please select the best answer from the choices provided
Answer:
D, C, B, A
Step-by-step explanation:
Given the prices below:
Store A: price $99.99 and discount of 15%
15% discount :
Discounted price : (1 - 0.15) * $99.99 = $84.99
Store B: price $95.99 and discount of 12%
12% discount :
Discounted price : (1 - 0.12) * $95.99 = $84.47
Store C: price $90.99 and discount of 10%
10% discount :
Discounted price : (1 - 0.10) * $90.99 = $81.89
Store D: price $89.99 and successive discounts of 5% and 5%
5% discount :
Discounted price : (1 - 0.05) * $89.99 = $85.4905
5% discount :
(1 - 0.05) * $85.4905 = $81.22
