What does x equal? no step by step needed.

Mathematics
1 answer:
Basile [38]3 years ago
7 0

Answer:

x = 13

Step-by-step explanation:

BD is the hypotenuse of the smaller triangle and corresponds to 2x - 7.  51 is the longer leg of triangle EFG

The ratio of the two hypotenuses is (2x - 7)/57, and the ratio of the two longer legs is (x + 4)/51.  These ratios are equal to one another.  Thus:

2x - 7      x + 4

--------- = ---------

   57          51

Cross multiplication results in 51(2x - 7) = 57x + 228, or

102x - 357 = 57x + 228

Combining like terms, we get:

45x = 585, and so x = 13.

How many kilometers is it from the main gate to Manatee Springs? (Hint: To convert from
Luda [366]

Answer:

Distance between Main gate M and manatee Spring S,

MS = 6.035 km ≅ 6 km (rounded off)

Step-by-step explanation:

Let the point at Train depot be T. Point at Main gate be M. Point at Bird sanctuary be B. Point at Elephant house be E. Point at manatee Springs be S.

Now, we have two triangles TMB and TSE.

From figure given that, ∠MTB = ∠STE

                                      ∠TMB = ∠TSE

                                       ∠TBM = ∠TES.

⇒ From AAA similarity, Triangles TMB and TSE are similar.

⇒ \frac{TM}{TS} = \frac{TB}{TE}

⇒ \frac{x}{4200} = \frac{2000}{3500}

⇒ x = 2400 yds

⇒ Distance between Main gate M and manatee Spring S,

MS = MT + TS = x + 4200 = 2400 + 4200 = 6600 yds

⇒ MS = 6600 yds = 6600 × 0.0009144 km = 6.035 km ≅ 6 km

*HELP ME PLEASE* Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Lubov Fominskaja [6]

Answer:

n  = -14

Step-by-step explanation:

Let us try to solve this equation for n;

     3x + 1 - 9  = 3(x + 2)  + n

     3x  - 8  = 3x + 6 + n

      3x - 3x -8 - 6  = n

              -14  = n

The value of n  = -14

This value is the value of the equation that will have no solution.

 To know if we are correct, let us input this value into the expression

        3x + 1 - 9  = 3(x + 2)  + n

        3x - 8  = 3x + 6 -14

 Collect like terms;

        3x - 3x  = 8 + 6 - 14

               0 = 0
