d=6−1=5

∴x=1+(n−1)×5

∴x−1=(n−1)×5

∴(n−1)=

Solve the formula Ax+Bx = c for y
IgorC [24]

Answer:

B

Step-by-step explanation:

The correct formula given is:

Ax+By=c

We need to solve for y. First, we isolate the "y" term:

Ax+By=c\\By=c-Ax

Now, there's a "B" with y, to isolate the "y", we need to divide both sides by "B" and get "y":

By=c-Ax\\\frac{By}{B}=\frac{c-Ax}{B}\\y=\frac{c-Ax}{B}

Answer choice B is right.

In triangle ABC, AB = 90 in., BC = 80 in., and angle B measures 50°. What is the approximate perimeter of the triangle?
Monica [59]

Answer:

The answer to your question is Perimeter = 287.3 in

Step-by-step explanation:

AB = 90 in

BC = 80 in

∠B = 50

Perimeter = ?

Process

1.- We need to find AC using Law of sines

\frac{sin A}{80} = \frac{sin 50}{90}

       sin A = \frac{80}{90} sin 50

       sin A = 0.68

              A = 42.9 ≈ 43

The sum of the internal angles in a triangle equals 180°

       A + B + C = 180°

       43 + B + 50 = 180

       B = 180 - 43 - 50

       B = 87°

\frac{AC}{Sin 87} = \frac{90}{sin 50}

AC = 90 \frac{sin 87}{sin 50}

      AC = 117.3

2.- Find the perimeter

     Perimeter = AB + BC + AC

     Perimeter = 90 + 80 + 117.3

     Perimeter = 287.3 in

In the storage room of a certain bakery, the ratio of sugar to flour is 5 to 8, and the ratio of flour to baking soda is 10 to 1
olasank [31]

Answer:

1,500

Step-by-step explanation:

Ratio of Sugar to Flour: 5:8 -> 25:40

Ratio of Flour to Baking Soda: 10:1 -> 40:4

Sugar to Flour to Soda: 25x:40x:4x

\frac{40x}{(4x+60)} = \frac{8}{1} -> x = 60

Sugar = 25x = 1,500

Hope this helps :)
