When solving an algebraic expression, our goal is to get the variable _______________ on one side of the equal sign.

Answer:

Lara will do a profit of 34 pence by 100 grams of birdseed.

Step-by-step explanation:

The given ratio means that there are 2 grams of peanuts and 3 grams of sunflower per each 5 grams of birdseed. Now, we obtain the amount required of peanuts and sunflower for 100 grams of birdseed by simple rule of three:

Peanuts

[tex]x = \frac{100\,g}{5\,g}\times 2\,g[/tex]

[tex]x = 40\,g[/tex]

Sunflower

[tex]y = \frac{100\,g}{5\,g}\times 3\,g[/tex]

[tex]y = 60\,g[/tex]

If we know that 10 grams of sunflower cost 9 pence and 10 grams of sunflower cost 3 pence, then the total cost of production of 100 grams portion:

[tex]C = \left(\frac{0.03\,GBP}{10\,g} \right)\cdot (40\,g)+\left(\frac{0.09\,GBP}{10\,g} \right)\cdot (60\,g)[/tex]

[tex]C = 0.66\,GBP[/tex]

And the profit done by Lara is:

[tex]\Delta C = 1\,GBP - 0.66\,GBP[/tex]

[tex]\Delta C = 0.34\,GBP[/tex]

Lara will do a profit of 34 pence by 100 grams of birdseed.

Answer: The length of the other diagonal is 8 cm.

Step-by-step explanation:

Area of rhombus = [tex]\frac{pq}{2}[/tex]

[tex]\frac{4q}{2} =16\\[/tex]

3:7 *4=12:28

3:7*3=9:21

They both can not equal 12:21

Yes, the given ratios 3:7 and 12:21 are in proportion.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

The given ratios are 3:7 and 12:21.

Here, the proportion is 3:7::12:21

The ratios to in proportions, product of means must be equal to product of extremes.

3×21=7×12

3×7=7×3

21=21

Yes, the given ratios are in proportion.

Answer:

x=1

Step-by-step explanation:

1/5(10x-20)=x-3

2x-4=x-3

2x-x=4-3

x=1

Answer:

The value of x is 1 after solving the linear equation.

Step-by-step explanation:

Given equation is:

[tex]\frac{1}{5}(10x-20)=x-3[/tex]

We will solve the equation by simplifying first.

[tex]\frac{1}{5}*10x-\frac{1}{5}*{20}=x-3\\2x-4=x-3[/tex]

Now, we will subtract x from both sides of the equation,

2x-x-4 = x-x-3

x-4 = -3

Next, we will add 4 on the both sides of the equation,

x-4+4 = -3+4

x = 1

Hence,

The value of x is 1 after solving the linear equation.

Answer:

A. 3.7, because |3.7| = 3.7

Step-by-step explanation:

What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.

Explicación paso a paso:

Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.

Dado

Función de costo C (x) = 43x + 1850

Función de ingresos R (x) = 80x

Obtener la función de ganancias

P (x) = R (x) - C (x)

P (x) = 80x - (43x + 1850)

P (x) = 80x - 43x - 1850

P (x) = 37x - 1850

Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:

P (351) = 37 (351) - 1850

P (351) = 12,987-1850

P (351) = 11,137

Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137

Answer:

1)6x

2)4

3)6x+4=2(3x+2)

Step-by-step explanation:

Answer:

x = 2/5 or 0.4

Step-by-step explanation:

3x - 6 = 4(2 - 3x) - 8x

distribute

3x - 6 = 4*2 - 4*3x - 8

3x - 6 = 8 - 12x - 8

combine like terms

3x - 6 = -12x

add 12x to both sides of the equation

3x - 6 + 12x = -12x + 12x

3x - 6 + 12x = 0

15x - 6 = 0

add 6 to both sides of the equation

15x - 6 + 6 = 0 + 6

15x = 6

divide both sides of the equation by 15

15x/15 = 6/15

x = 6/15

x = 2/5

x = 0.4

The probability of getting numbers whose sum is a multiple of three is,

⇒ 1 / 3

Since, The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here, We have;

There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;

12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66.

So, that is 16 out of 48 possibilities,

⇒ 16/48,

⇒ 1/3.

Thus, The probability of getting numbers whose sum is a multiple of three is,

⇒ 1 / 3
