Answer:

w = -6

Step-by-step explanation:

Like terms would be "terms" with the same variable. 5x and 4x would be like terms, because they have the same variable of x. 6y and 2x would not be like terms, because they have different variables (6y has the variable of y and 2x has the variable of x).

When combining like terms, we would add up the coefficients of the variables and then multiply that by the variable:

4x + 6x = (4 + 6)x = 10x

In other words:

ax + bx = (a + b)x

where x is any variable and a and b are constants.

We are given the equation:

10w + 4w = -84

and we have to solve the equation. To do this, we must first combine the like terms. And than we would try to get the equation into the for "w = _".

10w + 4w = -84

Combine the like terms 10w and 4w.

(10 + 4)w = -84

Simplify.

14w = -84

Divide both sides by 14 to get rid of the coefficient of 14 on the left side.

w = (-84) ÷ 14

Simplify.

w = -6

The solution would be w = -6.

I hope you find my answer helpful. :)

Justin bought some yarn from his Favorite craft store. He can make one score for 3/5 of a ball of yarn. If he purchases 15 balls

Svet_ta [14]

Justin can make 25 scraves with 15 balls of yarn

<h3><u>Solution:</u></h3>

Given that Justin can make one scarve for 3/5 of a ball of yarn

He purchases 15 balls of yarn

<em><u>To find: number of scarves Justin can make</u></em>

Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn

$\text {number of scarves }=\frac{\text { total yarn he has }}{\text { yarn needed for } 1 \text { scarve }}$

$\text {number of scarves }=\frac{15}{3 / 5}$

$\text {number of scarves }=\frac{15}{3} \times 5=25$

Thus he can make 25 scraves

What is the length of a short leg of a 30-60-90 triangle shown below?

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

since 30-60-90 triangles are special right triangles, we know that if the short leg=x, the long leg= xsqrt(3). so the short leg= 5 sqrt(3) /(sqrt(3) = 5

Which equation corresponds to the statement, to more than a number equivalent to Y

Mariana [72]

Answer:

English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2

Step-by-step explanation:

Two more than a number means we need to add 2 to a number.

Let suppose the number be = x

Two more than the number 'x' = x+2

As it is stated that two more than a number equivalent to Y.

Equivalent means something is equal to the given expression.

Mathematically, the 'equivalent' is represented by the symbol '='.

Thus, the English statement 'two more than a number equivalent to Y' can be algebraically represented as:

y = x + 2
