The correct expression for Jorge's age is (14 ÷ 2) + 3

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, Maya is 14 years old. Her brother Jorge is 3 years more than half her age.

We need to determine an expression for Jorge's age,

So, If you divide her age by two and add 3 then you will get Jorge age and that is what the question is asking,

i.e. (14 ÷ 2) + 3

Hence, the correct expression for Jorge's age is (14 ÷ 2) + 3

Answer:

The windowpane is 15 centimeters wide.

Step-by-step explanation:

Use the Pythagorean theorem:

a^2 + b^2 = c^2

400 + b^2 = 625

b^2 = 225

b = 15

Answer:

-0.3

Step-by-step explanation:

I think it is -0.3 because the other ones wouldn't make any sense if you put in on the number line but I'll come back when I finish the test to tell you if its right :)

Edit** It is correct I just took the test :)

For the point that divides the line segment XY into a ratio of 1:2,

Y value is -0.3.

Option A is correct

In coordinate geometry, Section formula is used to find the ratio in which a line segment is divided by a point internally or externally. It is used to find out the centroid, incenter and ex-centers of a triangle.

Given point

X = ([tex]x_{1},y_{1}[/tex]) = (-6,-1)

Y = ([tex]x_{2} ,y_{2}[/tex]) = (5,1)

Ratio = 1:2

For point (x1, y1) and (x2, y2) on coordinate plane if is divided in ratio of m:n.

Then section formula is given by [tex](\frac{mx_{2}+nx_{1} }{m+n},\frac{my_{2}+ny_{1} }{m+n})[/tex].

Using the section formula,

[tex](\frac{mx_{2}+nx_{1} }{m+n},\frac{my_{2}+ny_{1} }{m+n})[/tex]

= [tex](\frac{(1)(5)+2(-6)}{1+2} , \frac{1(1)+2(-1)}{1+2})[/tex]

= [tex](\frac{5-12}{3} ,\frac{1-2}{3})[/tex]

= [tex](\frac{-7}{3} ,\frac{-1}{3})[/tex]

x = -2.3 and y = -0.3

For the point that divides the line segment XY into a ratio of 1:2,

y value is -0.3.

Option A is correct

Step-by-step explanation:

-6x+8=4(5-x)

-6x+8=20-4x

12=2x

x=6

Answer:

-6

Step-by-step explanation:

-6x+8=20-4x

subtract 8 from both sides:

-6x+8-8=20-4x-8

simplifiy:

-6x=-4x+12

Add 4x to both sides:

-6x+4x=-4x+12+4x

simplifiy:

-2x=12

divied both sides by -4:

-2x/-2=12/-2

simplifiy:

x=-6

Answer:

  195 ft

Step-by-step explanation:

The relationship between the horizontal distance, angle, and vertical height is given by ...

  Tan = Opposite/Adjacent

Referring to the attached diagram, we have ...

  tan(16°) = BT/MB

  tan(25°) = BK/MB

Solving for BT and BK, we can describe their difference as ...

  BT = MB·tan(16°)

  BK = MB·tan(25°)

  BK -BT = 35 = MB(tan(25°) -tan(16°))

Dividing by the coefficient of MB gives ...

  MB = 35/(tan(25°) -tan(16°)) = 35/0.179562

  MB = 195 . . . feet

Marcos is standing 195 feet from the base of the tree.

Answer:

250

Step-by-step explanation:

250 ÷ 400 = 0.625 = 0.625 × 100/100 = (0.625 × 100)/100 = 62.5/100 = 62.5% Answer: Percentage of 62.5% of what number = 250?

The required number whose 62.5% is 2.25 is given as 3.6.

Given that,
To determine the number whose 62.5% is 2.25.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given that,
Let the number be x,
According to the condition,
62.5% of x = 2.25
0.625x = 2.25
x = 2.25/0.625
x = 3.6

Thus, the required number whose 62.5% is 2.25 is given as 3.6.

Answer:

(0,20)

Step-by-step explanation:

1) we can represent the situation as coordinates

lets have # of texts be "x" variable

lets have bill be "y" as the y variable is always the dependant variable and the cost of the phone bill is dependant upon the number of texts so

y=mx+b-slope-intercept form

coordinates: (50,25) and (100,30)

slope: (30-25)/(100-50)

5/50=1/10

hence slope=1/10

y=1/10x+b

substitute in a coordinate pair into this equation

25=50*1/10+b

25=5+b

b=20

hence y intercept is (0,20)
