How do I solve this? Show work please

Mathematics
1 answer:
Alecsey [184]2 years ago
7 0

Answer:

x=5 so x+1 = 6 and x+3 = 8

Step-by-step explanation:

It's all about proportions.    These are similar triangles, so corresponding sides are proportional.  Basically you want to solve an equation \frac{x+1}{x+3} = \frac{3}{4}

Let me know if you cannot see how EG corresponds to GH or how EF corresponds to IH.

Anyway, from here we just solve.  Again, let me know if you have any questions.

4(x + 1) = 3(x + 3)

4x + 4 = 3x + 9

x = 5

And you can check

[tex]\frac{6}{8} = \frac{3}{4}[/tex

Ivanshal [37]

<em>Answer</em>


D) 1

If a line is to be drawn from a point to a line or a plain it can only be one. In this case a line is to be drawn through a point A to a plane P. If the line is to be perpendicular, then is is only one.


From the choices, the appropriate answer is D) 1

A bicycle store installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The owner of th
dalvyx [7]
Dividing the number of tires that should be installed per day which  is 400 by the number of working hours which is 8 will give us 50 tires per hour. Assuming that the same mistake will take toll on the workers such that they will have 1 tire mistakenly installed in an hour, they will have 8 erroneous tires in a day. Multiplying this by 5 to make the answer per week will give 40. Out of the 400 x 5  = 2000 tires. The answer would be 2000 - 40 which is equal to 1940. The assumption must be valid.

Aliun [14]

Answer:

(1): "*-5x2y" was replaced by "*(-5x2y)".

(2): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

STEP

1

:

Equation at the end of step 1

 (3x • (y2)) • (0 -  (5x2 • y))

STEP

2

:

Equation at the end of step

2

:

 3xy2 •  -5x2y

STEP

3

:

Multiplying exponential expressions :

3.1    x1 multiplied by x2 = x(1 + 2) = x3

Multiplying exponential expressions :

3.2    y2 multiplied by y1 = y(2 + 1) = y3

I believe the answer is   ( -3•5x3y3)
