Answer:

-3.9

Step-by-step explanation:

Distribute:

-5.2(m + 3.4) = 2.6

-5.2(m) + -5.2(3.4) = 2.6

Multiply:

-5.2(m) + -5.2(3.4) = 2.6

-5.2m - 17.68 = 2.6

Add 17.68 on both sides:

-5.2m - 17.68 = 2.6

+17.68 +17.68

-5.2m = 20.28

Divide by -5.2 on both sides:

-5.2m = 20.28

/-5.2 /-5.2

m = -3.9

A rectangle is 3 times as long as it is wide. the perimeter is 16 feet. find the dimensions

astraxan [27]

Answer:

Width = 2 feet

Length = 6 feet

Explanation:

Variables:

Perimeter = p

Length = l

Width = w

Equation:

2w + 2l = p

It is given that:

l = 3w

and

p = 16 feet

With this information, we can rewrite the equation (substitute)

2w + 2(3w) = 16

Simplify

2w + 6w = 16

Add

8w = 16

Divide both sides of the equation by 8

Width = 2 feet

Length = 3(w) = 3(2) = 6 feet

Hope this helps :)

Find the inverse of the function f(x)=5x-6/x+2

Naily [24]

Answer:

$f^{-1}(x)=\dfrac{2x+6}{5-x}$

Step-by-step explanation:

Swap x and y, then solve for y.

$x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}$

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What

Zina [86]

Answer:

The total cost of the bond is none of the given choices.

Step-by-step explanation:

The selling price of a $1000 bond = $99.875

The brokerage fee = 5.5 %

Now, 5.5% of $99.875 = $\frac{5.5}{100} \times 99.875 = 5.493$

So, the brokerage fee = $5.493

Now, to find out the total cost of the bond:

Total Cost = The selling Price + Brokerage Price

= $99.875 + $5.493

= $105.368

or, the total price of the $1000 bond is $ 105.368.

Hence, the total cost of the bond is none of the given choices.

Please see photo below for question!!

Liono4ka [1.6K]

No need for the diagram (though it helps)

P(AUB) = P(A) + P(B) - P(A and B),

P(A) = 0.61 - 0.41 + 0.18 = 0.38

So, D!!

helen divides up some money to give to her eight nieces. if d represents the total amount, enter an expression to represent how

poizon [28]

1/8 d = how much each niece receives

Each niece receives(x) amount of money.1/8 of the money)

If you multiply this amount by 8 it will be the money Helen divides up to her 8 nieces 1/8dx8=8/8(the whole amount is 8/8)
