What is the value of x

Mathematics
1 answer:
goblinko [34]3 years ago
8 0

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3

The table represents a linear function.<br><br>what is the slope of the function?
belka [17]
As we see, the table shows 0 equals 4, so 4 is our y axis. we now know our equation is y=_x +4.
lets subtract and find the slope using
y1 - y2 \\ x1 - x2
7-4 3
1-0 1 the slope is 3. lets substitute.
1(3)+4=7
the slope is 3.

This figure represents a small weight that is to be covered on all sides with a floral fabric. How much fabric is needed to cove
Anon25 [30]

Answer:

77.5 cm²

Step-by-step explanation:

We need to find the surface area of the rectangular prism.

Total surface area = 2(lw + wh + lh)

where:

  • l = length of base
  • w = width of base
  • h = height of prism

Given dimensions:

\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm

\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm

\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm

Substituting these value into the formula:

\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}

Therefore, 77.5 cm² of fabric is needed to cover the weight.
