Answer:

20 years old

Step-by-step explanation:

The age of Eli would be 20 years old

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Consider E and F represent Eli and his Father's current ages.

We are told that E = (1/4)F.  

Eli is now one quarter of his father’s age.

But in 5 years, that will be:

(E+5) = (1/3)(F+5)      

In 5 years’ time his age will be one third of his father’s age.

We have two equations and two unknowns.  

To Find a way to eliminate one of the two variables and then solve for the remaining variable.

E = (1/4)F

(E+5) = (1/3)(F+5)

This seems to me the easiest would be to use the first equation's definition of E [=(1/4)F] in the second equation:

(E+5) = (1/3)(F+5)

((1/4)F+5) = (1/3)(F+5)

(1/4)F - (1/3)F = (1/3)*5 - 5

F - (4/3)F = (4/3)*5 - 20

-(1/3)F = (20/3) - (60/3)

-(1/3)F = (-40/3)

F = (120/3)

F = 40 years

E = 10 years  (based on E = (1/4)F)

In five years, F is 45 and E is 15, that would make Eli  1/3 of his father's age in 5 years.

Answer:

The Median is 37

Step-by-step explanation:

Answer:

the answer is thirty seven

37

it's the middle number

Answer:

T = 5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4=2/5t + 2

Step 2: Flip the equation.

2/5t + 2 = 4

Step 3: Subtract 2 from both sides.

2/5t + 2 − 2 = 4 −2

2/5t = 2

Step 4: Multiply both sides by 5/2.

(5/2) *(2/5t)= (5/2) *(2)

Answer:

t=5

Answer:

t=5

Step-by-step explanation:

4=2+2/5 t

Subtract 2 from both sides

2=2/5 t

Multiply 2/5 by its reciprocal on both sides so multiply by 5/2

(5/2) times 2 is 5

so t is 5

Answer:143.60 ft

Step-by-step explanation:

Given

Height of hill [tex]h=80\ ft[/tex]

the launch velocity of the rocket is [tex]u=64\ ft/s[/tex]

At maximum height, the velocity of the rocket is zero

using the third  equation of motion [tex]v^2-u^2=2as[/tex]

[tex]\Rightarrow 0^2-64^2=2\times (-32.2)\times s\\\Rightarrow s=\dfrac{64^2}{64.4}=63.60\ ft[/tex]

The maximum height will be [tex]80+63.60=143.60\ ft[/tex]

Answer:

4 ft. = height

8 ft. = base  

Step-by-step explanation:

Let h = length of the height

2h = length of the base

A = bh

32 = 2h(h) = [tex]2h^{2}[/tex]

[tex]h^{2}[/tex] = 16

h = 4 ft. = height

Answer:

All of the above

Step-by-step explanation:

The expression has a value greater than 253  is 253 x 9/2 and 253 x 4/1.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

Given:

We have to find the number whose value greater than 253.

1. 253 x 3/4

= 253 x 0.75

= 189.75

2. 253 x 5/5

= 253

3. 253 x 9/2

= 253 x 4.5

= 1138.5

4. 253 x 6/7

= 216.85

5. 253 x 4 /1

= 1012

Thus, the Expression having value greater than 253 is 253 x 9/2 and 253 x 4/1.

Answer:

y=2x-5

Step-by-step explanation:

Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.

Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.

y=2x+b

Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.

Answer:

From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).

Step-by-step explanation:

Hope I helped You :) have a good day.

The coordinates of point O of the given Reflection is; 5, 5

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Since,  The coordinates point is missing and so I have attached it.

Now, from the question, we are told that N is the reflection of B and O is the reflection of C.

Thus, from the attached image, drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines would give us the location of point O.

Hence, Drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines which is point O has coordinates at (5,5).

Answer:

Expression A: (8 * 500-400) / 4

Step-by-step explanation:

The other expression doesn't work because of the order of operations, you would multiply the 8*500, which is correct, but then you would divide 400 by 4 before subtracting it from 500, which is wrong.
