Answer:

\boxed{\bold{x=-\frac{7}{3}}}

Step-by-step explanation:

Expand: \bold{5\left(2x\right): \ 10x}

Expand: \bold{7\left(x-1\right): \ 7x-7}

\bold{10x=7x-7}

Subtract 7x From Both Sides

\bold{10x-7x=7x-7-7x}

Simplify

\bold{3x=-7}

Divide Both Sides By 3

\bold{\frac{3x}{3}=\frac{-7}{3}}

Simplify

\bold{x=-\frac{7}{3}}

Which THREE pairs of measurements are possible side lengths for a 30-60-90 triangle?
9966 [12]

Answer:

1, 5 and 6.

Step-by-step explanation:

The sides of this triangles has lengths in the ratio x : √3x : 2x where 2x is the hypotenuse.

When C = 30,  the side AB is the small leg  (=x).

When B = 90, the hypotenuse is  AC ( =2x).

When A =  60, the larger leg is BC (=√3x).

1.  AB = 4, BC = 4√3 :- Are possible legs.

5 AB = 7, AC = 14. :-  AB = small leg, AC = hypotenuse.

6. AB = 11, BC = 11√3:-   AB = small, BC = larger leg.

A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside
melamori03 [73]

For a non-resident:

C_{nr}=8d+2.5d=10.5d

For a resident:

C_{r}=114+1d

We want to know the number of days d such that the two costs are equal ie \{d|C_{nr}(d)=C_{r}(d)\}

To do this set the two costs equal to each other:

C_{nr}=C_{r}

10.5d=114+1d

And solve for d:

10.5d-1d=114+1d-1d

9.5d=114

d=\frac{114}{9.5}

d=12

The costs will be equal when a resident and a non-resident each use the beach for 12 days.
