Answer:

x = 30

Step-by-step explanation:

Given 2x, 3x, x, as the interior angles of the ∆, since sum of interior angles of ∆ = 180°, equation to solve for the value of x is given as:

2x + 3x + x = 180

Combine like terms

6x = 180

Apply the inverse operation of multiplication to solve for x. Since 6 is multiplying x = 6x, to get the value of x, the inverse operation of multiplication is division. Therefore, we would divide each side of the equation by 6.

\frac{6x}{6} = \frac{180}{6}

x = 30

Which of the following represents a first step in solving the equation (x-7)2=100
Alex787 [66]
Will start to distribute the 2 in (x-7)
so it can be (2x-2*7)=100
(2x-14)=100
2x=100+14
2x=114
x=114/2
x=57

Use the associative property to identify which expression is equal to (10)(5x)(7). 1.(7)(5x)(10) 2. 10(5x + 7) 3. (5x)(10)(7) 4.
8090 [49]
Associative property is dealing with parentahsees and orders
it is
a(bc)=(ab)c and
a+(b+c)=(a+b)+c

so we want the multiplication one

given
(10)(5x)(7)
we can arragnge these a number of ways (we should use commutative property, but whatever)

first one works, the 7 was moved to front
2nd is wrong, that is a wierd version of the distributive
3rd is right, 5x was moved to the front
4th is wack, no bueno


answer is 1st and 3rd options

Rewrite equation to solve for m 4n-6m=-2
hram777 [196]

Answer:

Step-by-step explanation:

4n - 6m = - 2              Subtract 4n from both sides.

4n-4n - 6m = -2-4n

-6m = - 2 - 4n             Divide by - 6

-6m/-6= -2/-6 -4n/-6  Do the division

m = 1/3 + 2n/3

The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.
