Answer:

it should be the first one -28

Step-by-step explanation:

7(8-x)=-5x

distribute the 7 to 8 and -x

56-7x=-5x

then you add 7x to both sides

56=-2x

lastly you divide both sides by -2

-28 = x

hope this helps

Answer:

x = 28

Step-by-step explanation:

7(8 - x) = -5x

56 - 7x = -5x                 Distribute 7 to the parenthesis

56 = 2x                         Add -7x to both sides

28 = x                           Divide 2 to both sides

Given that a=43 ,b=82 , and c=28, solve triangle abc. round to the nearest tenth.
Virty [35]

Answer:

NO triangle exists.

Step-by-step explanation:

Given that the sides of the triangle are  a=43 ,b=82 , and c=28

To solve for unknown angles of the triangle

PLease refresh the triangle rule of inequality that the sum of any two sides is always greater than the third side

Before solving the triangle, let us check whether this is true.

a+b >c

b+c>a

But a+c is not greater than b.

Hence there cannot be any real triangle with these sides given.

Answer is no triangle exists.

HIGH SCHOOL MATH ....
umka21 [38]

Answer:

The value of B (base\ area) = 27m^2

Step-by-step explanation:

Let's recall the the formula for volume of a pyramid.

Volume of a Pyramid = \frac{1}{3}\times B\times H}....equation (1)

where B=Base\ area (m^2) and H=height\ (m)

Now we have been given the values of V and H and have to find the value of B

Plugging the values of V and H in equation (1)

B=\frac{3\times V}{H}= \frac{3 \times 81}{9} = 27\ m^2

Now we can also check our previous results.

V = \frac{24\times 7}{3}=8 \times 7 =56\ m^3

So, our final answer is 27\ m^2

Rebah and her twin brother are planning a birthday party at Pizza Pete's. There is a S64.75 charge to reserve a party room plus
Digiron [165]

Answer:

22 people

Step-by-step explanation:

Step 1: I first subtracted $64.75 from $175.00 so that I knew how much would be leftover after the charge of the room, because you can't count that cost. When I did this, I got $110.25. So then I knew how much was paid other then for the room.

Step 2: I then divided $110.25 by $4.95, so I would get the amount of people who went to the party, since each person costs $4.95. When I divided, I got 22.

So that would be my answer. I hope that helps. :)
