-8=-(x+4) I need help with this I can't figure it out

Answer:

x = 4

____________________________________________________

Explanation:

We're solving the equation: -8=-(x+4)

Solve:

-8=-(x+4)

Distribute the negative to the variables in the parenthesis.

-8 = -x - 4

Add 4 to both sides

-4 = -x

Divide by -1

4 = x (same as x = 4)

Two sides of a triangle have the same length. The remaining side is one third as long as each of the other sides. If the perimet

mixas84 [53]

Answer:

Therefore the length of each sides of a triangle are 135 cm , 135 cm and 45 cm.

Step-by-step explanation:

Let the two sides of a triangle having same length be 'x' cm

According to given condition the third side will be $\dfrac{x}{3}$

Perimeter of the triangle = 315 cm.

To Find:

what is the length of each side =?

Solution:

Let we name the triangle as ΔABC having sides

$AB = AC = x$

$BC=\dfrac{x}{3}$

We know that very Perimeter of a Triangle is given by the sum of all the sides,

$\textrm{Perimeter of a Triangle ABC}=AB+BC+AC$

Substituting the values we get

$315=x+\dfrac{x}{3}+x=\dfrac{7x}{3}\\\\x=\dfrac{945}{7}=135\\\\\therefore x=135\ cm$

substituting 'x' for the third side we get

$BC=\dfrac{135}{3}=45\ cm$

Therefore,

$AB = AC = 135\ cm$

$BC=45\ cm$

Therefore the length of each sides are 135 cm , 135 cm and 45 cm.

Step-by-step explanation:

The given daily temperature in New York from Monday to Thursday:

Monday: $1^{\circ}C$

Tuesday: $2^{\circ}C$

Wednesday: $5^{\circ}C$

Thursday: $-1^{\circ}C$

Now, among the given temperatures, $1^{\circ}C, 2^{\circ}C, 5^{\circ}C,$ and $-1^{\circ}C,$ the highest temperature is $5^{\circ}C$ .

As the day having the highest temperature is the warmest day which is Wednesday.

So, on Wednesday the temperature was warmest.
