Answer:
45
Step-by-step explanation:
18+27=9(2+3)=9(5)=45
The sum of the numbers 18 and 27 will be 45.
What is the greatest common factor?The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. The greatest common multiple is the common number multiplied by both numbers.
The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.
Given sum is 18 + 27. The greatest common multiple between the two numbers is 9 take it common and then solve.
E = 18+27
E =9(2+3)
E =9(5)=45
Therefore, the sum of the numbers 18 and 27 will be 45.

Answer:
The slope is 2
Step-by-step explanation:
To solve for slope, it's: y2-y1/ x2-x1.
The points can be (1,0) and (2,2) since they intersect with the slope.
You plug the points into the equation which is 2-0/ 2-1.
This will give you 2/1 or just 2.
Or you can just do rise over run. The slope is going up by 2 and across by 1.
El triple del cuadrado de un numero es igual a 6 veces ese numero cual es el numero que satiface el problma
Answer:
El numero es 2
Step-by-step explanation:
Sea x el número.
A partir de la pregunta, la expresión se puede representar matemáticamente como:
[tex]3x ^ 2 = 6x[/tex]
Divide ambos lados de la expresión por x
[tex]\frac{3x ^ 2}{ x} = \frac{6x }{ x}[/tex]
[tex]\frac{3x ^ 2}{ x} = 6[/tex]
[tex]3x = 6[/tex]
Divide ambos lados de la expresión por 3
[tex]\frac{3x}{3} = \frac{6}{3}[/tex]
[tex]x = \frac{6}{3}[/tex]
[tex]x = 2[/tex]
Por tanto, el número es 2

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train. If the two trains are 400 miles apart after 2 hours, what is the rate of the eastbound train?
Answer:
Rate of the Eastbound train is 93 mph.
Step-by-step explanation:
Let the speed of the Eastbound train = x miles per hour
And the speed of the West bound train = y mph
Eastbound train travels 14 mph slower than the westbound train,
So the equation will be,
y - x = 14 ----------(1)
If these trains are 400 miles apart after 2 hours,
Distance traveled by the Eastbound train = Speed × Time
= 2x miles
Distance traveled by the Westbound train = 2y miles
Trains are 400 miles apart after 2 hours,
So the equation will be,
2y + 2x = 400
x + y = 200 ----------(2)
By adding equation (1) and equation (2)
(y - x) + (x + y) = 14 + 200
2y = 214
y = 107 mph
From equation (1)
107 - x = 14
x = 107 - 14
x = 93 mph
Therefore, rate of the Eastbound train is 93 mph.
A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow? Do not include units (yards) in your answer. Modified from EngageNY ©Great Minds Disclaimer
Answer:
2/5 yards of fabric
Step-by-step explanation:
A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow?
5 identical pillows = 2 yards of fabric
1 pillow = x yards
Cross Multiply
x yards × 5 pillows = 2 yards × 1 pillow
x yards = 2 yards × 1 pillow/5 pillows
x yards = 2/5 yards of fabric
Therefore, 2/5 yards of fabric was used for 1 pillow
What is 5/6 of 18? Its a fraction.
Answer:
Step-by-step explanation:
5/6 x 18 = 5 x 18/6 = 5x3 = 15
The requried, fraction 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.
To find 5/6 of 18, we set up the expression as follows:
(5/6) * 18
To multiply a fraction by a whole number, we simply multiply the numerator (the top number) of the fraction by the whole number. The denominator (the bottom number) remains the same. In this case, we have:
(5 * 18) / 6
Now, we multiply the numerator 5 by the whole number 18:
5 * 18 = 90
So, we have:
(90) / 6
Simplify the fraction.
To simplify the fraction, we divide the numerator (90) by the denominator (6):
90 / 6 = 15
Therefore, 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.

Find the equation of a line that passes through the point (4,2) and has a gradient of 5.
Leave your answer in the form y = mx + c
Answer:
The equation of a line in the slope-intercept form is:
y = 5x - 18
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptIn our case, we are given
m = 5Point (4, 2)now substituting m = 5 and (4, 2) in the slope-intercept form of the line equation to determine the y-intercept
y = mx + b
2 = 5(4) + b
20 + b = 2
subtract 20 from both side
20 + b - 20 = 2 - 20
b = -18
now substituting b = -18 and m = 5 in the slope-intercept form of the line equation
y = mx + b
y = 5x + (-18)
y = 5x - 18
Therefore, the equation of a line in the slope-intercept form is:
y = 5x - 18

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The height of the tree is equal to 98 feet.
What is Tangent (Tanθ)?
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Using the tangent function of the trigonometry, we can write the ratio of the height to the base will be equal because the angle of sun rays is the same for both.
Height of Tree /Shadow of Tree = Height of the biologist / Shadow of the biologist
Height of the tree/ 28 = 7/2
Height of the tree = (28×7)/2
Height of the tree = 98 feet
Hence, the height of the tree is equal to 98 feet.

The corresponding angles of the triangles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
In triangle ΔLMN, the measure of the third angle is calculated as,
∠N + ∠M + ∠L = 180°
∠N + 51° + 36° = 180°
∠N = 93°
In triangle ΔFGH, the measure of the third angle is calculated as,
∠H + ∠F + ∠G = 180°
∠H + 51° + 36° = 180°
∠H = 93°
In triangles ΔFGH and ΔMLN, the corresponding angles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.

FITNESS CLASSES Toshelle wants to take strength training classes at the community center. She has to pay a one-time enrollment fee of $ 25 to join the community center, and then $ 45 for each class she wants to take. Write an equation in slope-intercept form to represent the cost of taking x classes.
Answer:
y = 45x + 25
Step-by-step explanation:
Slope-intercept equation/form:
y = mx + b
________________________
x is the amount of classes that Toshelle will take and each class costs $45.
So, you multiply them by one another to get:
45x
_________________________
Additionally, there is a one-time payment of $25.
So, you add 25 to the cost to get:
+25
__________________________
y is the total amount of money Toshelle has to pay.
Therefore, you place 45x and +25 into a slope-intecept equation/form to get:
y = 45x + 25

Answer:
15.01
Step-by-step explanation:
BASIC RULES FOR ROUNDING
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Tony has $300 in his bank account. He takes out $10 each week for "W" weeks. After "W" weeks he has "D" dollars left in his bank account. Write an equation that represents the amount of money left in his bank account after "W" weeks.
Answer:
The Equation :
D = 300 - 10W
Step-by-step explanation:
We are told in the above question that:
Tony has $300 in his bank account. He takes out $10 each week for "W" weeks.
Where W = number of weeks
Our Equation is written as
Total amount in the bank account - $10 × W
= $300 - $10 × W
The Equation is given as
D = 300 - 10W
