Remember
anything times 1=same thing and

x/x=1 where x=x
so
mutliply both fractions by what makes the bottom numbers 40
1/5
5 times what=40?
answer is 8
multily by 1 or 8/8
1/5 times 8/8=8/40

7/8
8 is bottom
8 times what is 40? answer is 5
multiply by 1 or 5/5
7/8 times 5/5=35/40
1/5=8/40
7/8=35/40
they are not equal

No because you multiply 1/5 by 8 ans you will get 8/40 mean while you got 7/8 and multiply that by 5 and you get 35/40 so the answer is no

Solve for m m m Please help!!!

jarptica [38.1K]

Answer:

m∠ TRS = 60° , m∠ SRW = 120°

Step-by-step explanation:

First, find x

∠TRS = ∠VRW (vertically opposite angles are equal)

x + 40° = 3x

x - 3x = -40

-2x = -40

x = -40/-2

x = 20

m∠ TRS = 60° [x + 40 = 20+40 = 60]

m∠ SRW + m∠ TRS = 180° (linear pair)

m∠ SRW + 60° = 180°

m∠ SRW = 180° - 60°

m∠ SRW = 120°

hope this helps you

Which ofnthe following shows the correct use of distributive property when solving 1/3(33-x)=135,2

madam [21]

Answer: OPTION C.

Step-by-step explanation:

The missing options are:

$A. (33 - x) = \frac{1}{3} * 135.2\\\\B. (\frac{1}{3} *33) - \frac{1}{3} x = \frac{1}{3} * 135.2\\\\C.(\frac{1}{3} * 33) - \frac{1}{3} x = 135.2\\\\D. (\frac{1}{3} * 33) + \frac{1}{3} x = 135.2$

In order to solve this exercise you need to remember the following:

1. The Distributive property states that:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2. The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

In this case the exercise gives you the following equation:

$\frac{1}{3}(33-x)=135.2$

Since you need to solve for the variable "x" in order to find its value, the first step you must apply in the in the procedure is to eliminate the parentheses applying the Distributive property.

Then, you must multiply everyting inside the parentheses by $\frac{1}{3}$ .

Therefore,based on the explanation, you know that the correct use of the Distributive property is:

$\frac{1}{3}*33-\frac{1}{3}x=135.2$

El valor de la x que permite resolver la ecuacion 3x-6=12

kupik [55]

Lo siento, si me equivoco en español no es mi lengua materna

Answer: x es 6

Step-by-step explanation:

3x-6=12

Agrega 6 en ambos lados.

-6 se cancela y 12 + 6 es igual a 18.

Dividir por 3 en ambos lados

3x se cancela y 18 dividido entre 3 es igual a 6.
