tekilochka [14]3 years ago
4 0

Step-by-step explanation:

Lets begin with this 4x-25=x+14, 3x=39, so x=13, than we plug it in to side NP because that is the most simple one to plug it into to and that side is 27 since the triangle is equilateral all sides are the same so it is 27, 27, 27, for the sides and x=13

What is the constant of proportionality in the equation?
IrinaVladis [17]

Answer:

The constant of proportionality is option D i.e 5.

Step-by-step explanation:

Variation:

Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.

  1. Direct variation
  2. Inverse variation

Direct Variation:

Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.

Example y=kx

where, k  is constant of proportionality.

The above given example is of Direct Variation

∴ y = 5 x

∴ k = 5 = constant of proportionality.

Inverse Variation:

Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

Example yx=k

where, k  is constant of proportionality.

The sum of two numbers is 67 . the larger number is 5 more than the smaller number. what are the numbers?
Scorpion4ik [409]
Call the numbers x and y. According to the first sentence, x + y = 67. According to the second sentence, x = y + 5. You can combine these two equations to find the values of these variables:

x + y = 67
(y + 5) + y= 67
2y = 62
y = 31

You can use this to find x by plugging in y to either original equation:

x = y + 5
x = 31 + 5
x = 36

a triangle with a base of 6cm and a height of 8cm is similar to a triangle with base 21cm. What is the height of the second tria
Greeley [361]
Make a proportion.

Do base over height; \frac{base}{height}.

\frac{6}{8} =  \frac{21}{h}
h is the height of the second triangle. Solve for h.

Cross multiply.
\frac{6}{8} = \frac{21}{h} 
6h = 168
h = 28

The height of the second triangle is 28 cm.
