Emiliano divided by two instead of multiplying. To solve the equation, he had to multiply both sides by two so that he could see what x equals when it's alone (if half of x is 80, x, or two halves, is 160).

The solution of the given equation is 160. Emiliano wrong because instead of multiplying he must have divided 80 by 2.

The given equation is 1/2 x=80.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of the given equation is

1/2 x=80

⇒ x =80×2

⇒ x =160

The solution of the given equation is 160. Emiliano wrong because instead of multiplying he must have divided 80 by 2.

Answer:

y = 35x - 146

Step-by-step explanation:

You just have to use the point-slope equation of a line which is (y - h) = m(x - k) where (h, k) is the point given and m is the slope given. Therefore, plug in h = 4, k = -6, m = 35 into the equation to get:

(y - ( -6)) = 35(x - 4) which simplifies to

y + 6 = 35x - 140 and if you want it in standard form, it is

y = 35x - 146

The answer is B. Hope this helps!

The point (-4,0) will be the ordered pair of the equation 3x + 2y = -12. The correct option is B.

An equation of the line is defined as the linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line is y = mx + c, where m is the slope and c is the intercept cut by the y.

To calculate the ordered pair by satisfying the equation with each pair of points.

3(-6)+2(7)= -4

3(-4)+2(0)=-12 YES

3(0)+2(7)=14

3(3)+3(-3)=0

3(6)+2(0)=18

Therefore, the point (-4,0) will be the ordered pair of the equation 3x + 2y = -12. The correct option is B.

Answer:

6 Km / hour

Step-by-step explanation:

Convert distance to Km ( 1 Km = 1000 m )

150 m = 150 ÷ 1000 = 0.15 Km

Convert 1.5 mins to hours ( 1 hour = 60 minutes )

1.5 = 1.5 ÷ 60 = 0.025 hours

average speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{0.15}{0.025}[/tex] = 6 Km / hour

The average speed in km per hour is 6 kilometers per hour

The given parameters are:

Convert meters to kilometers

Distance = 150/1000 km

Distance = 0.15 km

Convert minutes to hours

Time = 1.5/60 hour

Time = 0.025 hour

The average speed is then calculated as:

Speed = Distance/Time

This gives

Speed = 0.15 km/0.025 hour

Evaluate

Speed = 6 kilometers per hour

Hence, the average speed in km per hour is 6 kilometers per hour

Answer:

  B.  False

Step-by-step explanation:

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

There is nothing in the diagram to require the triangles be congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

The index form of the fraction  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] where the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

Given data:

In index form, the expression  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] , where the base is 7 and the exponent is -1/5. This means that we are taking the reciprocal of the fifth root of 7. The exponent of -1/5 indicates that we are essentially finding the inverse of the fifth root of 7.

When dealing with fractional exponents, the denominator of the fraction becomes the root, and the numerator becomes the power to which the base is raised. In this case, the base is 7, the denominator is 5, and the numerator is -1. So, [tex]7^{(\frac{-1}{5})}[/tex]  represents the reciprocal of the fifth root of 7, which can also be expressed as the fifth root of 7 raised to the power of -1.

Hence, the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

h = 8

Surface area = 66π

2πr(r +h) = 66π

2πr(r + 8) = 66π

[tex]r(r + 8) =\dfrac{66\pi }{2\pi }[/tex]

r² + 8r = 33

r² + 8r - 33 = 0

r² + 11r - 3r - 33 = 0

r(r + 11) - 3(r + 11) = 0

(r +11 ) (r - 3) = 0

r - 3 = 0             {Ignore r = -11 as radius will not have negative value}
