I have lakes with no water, mountains with no stone and cities with no buildings. What am I?

Answer:

Step-by-step explanation:

a) set up the variables

Let x represent the first number Then  y will represent the second number.

b) What is the equation that represents the above situation?

c) Solve the equation.

Substitute x in the second equation and solve for y:

Then find x

Answer:

[tex]\tt{34~and ~17 }[/tex]

Step-by-step explanation:

let the first number is =x

second number is =y

The sum of two numbers is 51 =x+y=51•••{1}

the greater number is twice the smaller number= x=2y••••••••{2}

According to the question,

[tex]\bold{ x+y=51 }[/tex]

[tex]\bold{2y+y=51 }[/tex] [tex]\because{ (x=2y ) }[/tex]

[tex]\bold{ 3y=51 }[/tex]

[tex]\bold{ y=\dfrac{51}{3} }[/tex]

[tex]\boxed{\blue{y=17 } }[/tex]

NOW put the value y in equation {2}

we get that,

[tex]\bold{ x=2×17 }[/tex]

[tex]\bold{ x=34 }[/tex]

Answer:

angles

Step-by-step explanation:

trust me

The relationship between the angles created by the intersection of 2 parallel lines are solved

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

Let the first line be represented as m

Let the second line be represented as n

Now , the lines m and n are parallel lines

And , let the transversal line be t , which intersects m and n

So , Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

Hence , the angles formed are solved

Answer:

50/100 or 1/2

Explanation:

A 50-50 chance that a randomly selected adult has pierced ears means there's is a 50 percent probability of randomly selecting an adult that has pierced ears. In other words, there is half chance of selecting such an adult. A zero or one probability means there is either no possibility of selecting an adult with pierced ears or it is sure that a random adult would have pierced ears

Answer:

a unit means that we have one of something the unit rate means we have a rate for one or something we write the rate as a ratio with a denominator of 1

so false

Answer:A rate is a comparison of two different quantities with different units, one is generally time. Rates are always ratios, since they are comparing two different numbers as they compare two different quantities. Ratios are sometimes rates, but not always; we can compare different numbers without comparing measurements.

Answer:

54

Step-by-step explanation:

The Median of the data 78,56,22,34,45,54,39,68,54,84

Median of a data is the value at the middle after rearrangement

Rearrange in ascending 0rder

22, 34, 39, 45), 54, 54, (56, 68, 78, 84

The two numbers at the middle are 54 and 54

Median = 54 + 54/2

Median = 108/2

Median = 54

Hence the median of the data is 54

Answer:

216 inches of ribbon is needed.

216 inches of ribbon will cost Bryon $108.

Step-by-step explanation:

multiply 12 x 18

12 x 18 = 216

216 inches of ribbon need to be used to cover the frame.

To find the cost multiply 216 and 0.5

216 x 0.5 = 108

It will cost Bryon $108 for 216 inches of ribbon.

Answer:

y = 127 + 5x

Step-by-step explanation:

Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0

Let x = number of weeks Olivia deposits money.

y = Total pint of money that Olivia has in her account after x weeks

Hence, the function represents the amount in Olivias savings account after x weeks is ;

y = $127 + $5 × x

x < 0

y = 127 + 5x

Answer:

0

Step-by-step explanation:

Answer:  y = 1/4 x – 4

OR y = x/4 –4

m is the slope. b is the y-intercept.

Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 1/4 and the y-intercept is -4

Step-by-step explanation: To find the slope, m, determine  "rise over run"

Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–4,–5), (0,–4) and (4,–3)

The "rise" is the difference in y-values. Here, they increase by 1.

The "run" is the difference in x-values. Here they increase by 4.

So the slope is 1/4. Put that in place of m.

The graphed line crosses the y-axis at –4

That is the y-intercept.  Use -4 in the place of  b

Keep the y and x; substitute the values for m and b we found.

y = 1/4 x – 4

OR

y = x/4 – 4  This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be divided by 4.

Step-by-step explanation:

Answer:

400 people english, 240 spanish, 120 vietnamese and 40 other

Step-by-step explanation:

50% is half of 800.

half of 800 is 400. 400 use english

to find 10 percent, you divide by 10. to find 30, you multiply that by 3.

80 times 3 is 240. 240 use spanish.

15 percent is 10 percent, which is 80, +40 because of the 5 percent

80+40 is 120. 120 use vietnamese.

5 percent is half of ten percent.

half of 80 is 40.

and it all adds up to 800
