Answer:

x = -15 thus c: is your answer

Step-by-step explanation:

Solve for x:

10 = (-2 x)/3

10 = (-2 x)/3 is equivalent to (-2 x)/3 = 10:

(-2 x)/3 = 10

Multiply both sides of (-2 x)/3 = 10 by -3/2:

(-3 (-2) x)/(2×3) = (-3)/2×10

(-3)/2×(-2)/3 = (-3 (-2))/(2×3):

(-3 (-2))/(2×3) x = (-3)/2×10

(-3)/2×10 = (-3×10)/2:

(-3 (-2) x)/(2×3) = (-3×10)/2

(-3)/3 = (3 (-1))/3 = -1:

(-2-1 x)/2 = (-3×10)/2

(-2)/2 = (2 (-1))/2 = -1:

--1 x = (-3×10)/2

(-1)^2 = 1:

x = (-3×10)/2

10/2 = (2×5)/2 = 5:

x = -35

-3×5 = -15:

Answer:  x = -15

Identify the lateral area and surface area of a regular square pyramid with base edge length 5 in. and slant height 9 in.
Galina-37 [17]
Note that a squared pyramid has a square base & 4 equal triangles.
To find the lateral the lateral area you calculate the area of the 4 equal triangles  and to find the surface area (total Area) you add the area of the base:

Area of each triangle = side (5) x slant (9) and you divide by 2

==>Aera of 1 triangle = (9x5)/2 = 45/2 & for the 4 triangles

Lateral area = (45/2) x 4 = 90 in²

Now the base area (square) = 5 x 5= 25 in²

so the surface area = 90+25 = 115 in² (answer a)

Tod begins piano practice at 4:15 p.M. And ends at 5:50 p.M. How long does he practice
nikdorinn [45]

Answer:

95 minutes/1 hour and 35 minutes.

Step-by-step explanation:

Since there are 60 minutes in a hour you could convert it. Or you could just subtract 550 minutes by 415 minutes and get 95 minutes which is also 1 hour and 35 minutes.

Hope this helps

What numbers that have the same sign equal -4 3/5
djverab [1.8K]

Answer:

In mathematics, equality is a relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object. The equality between A and B is written A = B, and pronounced A equals B.[1][2] The symbol "=" is called an "equals sign". Two objects that are not equal are said to be distinct.

Step-by-step explanation:

For example:

{\displaystyle x=y}x=y means that x and y denote the same object.[3]

The identity {\displaystyle (x+1)^{2}=x^{2}+2x+1}{\displaystyle (x+1)^{2}=x^{2}+2x+1} means that if x is any number, then the two expressions have the same value. This may also be interpreted as saying that the two sides of the equals sign represent the same function.

{\displaystyle \{x\mid P(x)\}=\{x\mid Q(x)\}}{\displaystyle \{x\mid P(x)\}=\{x\mid Q(x)\}} if and only if {\displaystyle P(x)\Leftrightarrow Q(x).}{\displaystyle P(x)\Leftrightarrow Q(x).} This assertion, which uses set-builder notation, means that if the elements satisfying the property {\displaystyle P(x)}P(x) are the same as the elements satisfying {\displaystyle Q(x),}{\displaystyle Q(x),} then the two uses of the set-builder notation define the same set. This property is often expressed as "two sets that have the same elements are equal." It is one of the usual axioms of set theory, called axiom of extensionality.[4]
