Answer: 18
Step-by-step explanation: 18 would be your answer because if you do 5-2 you would get 3 and then you would do 18/3 which is 6 and 6 times 3 equals 18. If you need help when doing this use PEMDAS which stands for parentheses, exponents, multiplication, division, addition, and subtraction.
19.87 but there’s a 20% discount what’s the answer now?
19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.
find the length of side a
Answer:
a = 4
Step-by-step explanation:
a² = 5² - 3²
a² = 25 - 9 = 16
√16 = 4
a = 4
Answer:
a = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 3² = 5²
a² + 9 = 25 ( subtract 9 from both sides )
a² = 16 ( take the square root of both sides )
a = [tex]\sqrt{16}[/tex] = 4

Step-by-step explanation:
1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.
[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]
2) Use square sum: ( a + b )² = a² + 2ab + b².
[tex](10x + 9 {)}^{2} [/tex]
Hence, the answer is (10x + 9)².

Matti has one more pencil than Chang-Lin. Renaldo had three times as many as Chang-Lin, and one more than Jorge. Jorge has 5 pencils, how many pencils does Matti Have?
Answer:Matti has 3pencils
Step-by-step explanation:
Given that Jorge has 5pencils
Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils
But also
Renaldo =3Chang-Lin
6==3Chang-Lin
Chang-Lin = 6/3 =2
Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils

Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?
Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.

Answer:
(x -2)² +(y -4)² = 25
Step-by-step explanation:
The area of a square is half the product of the diagonals, so that product is 50·2 = 100. This is the square of the diameter, so the square of the radius is 100/4 = 25. Then the circle equation is ...
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
(x -2)² +(y -4)² = 25

Write the ratio in its simplest form:
Convert
2m : 8cm: 40mm
Answer:
2000mm:80mm:40mm
because 1 m is 1000mm and 1 cm is 10 mm so 2m will be 2000 mm and 8cm will be 80 mm
The simplified ratio will be equal to 10 : 40: 2.
What is a ratio?In mathematics, a ratio is a comparison between two quantities or numbers. It is expressed as the quotient or fraction of one number divided by another.
To simplify the ratio of 2m: 8cm: 40mm, we need to convert all the measurements to the same units. One meter is equal to 100 centimeters, so we can convert meters to centimeters by multiplying by 100. One centimeter is equal to 10 millimeters, so we can convert centimeters to millimeters by multiplying by 10.
2m: 8cm: 40mm
= 200cm : 8cm : 40mm (2m = 200cm)
= 200cm : 800mm : 40mm (8cm = 80mm)
= 10 : 40 : 2 (divide all terms by 40 to simplify)
Therefore, the simplified ratio is 10 : 40: 2.

An advertising flyer shows address labels as 4.3 cm by 1.2 cm. The ratio of the flyer label to the actual label is 2:3. What are the dimensions of the actual address labels?
Answer:
6.45 cm by 1.8 cm
Step-by-step explanation:
Ratio of label to actual measurement ; 2 : 3
For a flyer label size of 4.3
Actual label size equals :
(Flyer ratio / total ratio) * total size = flyer size
2/5 * x = 4.3
2x / 5 = 4.3
2x = 21.5
x = 21.5 / 2
x = 10.75
Actual size =. 10.75 - 4.3 = 6.45 cm
2/5 * x = 1.2
2x / 5 = 1.2
2x = 6
x = 6 / 2
x = 3
Actual size = 3 - 1.2 = 1.8 cm
6.45 cm by 1.8 cm

Write out the equation in slope-intercept form:
y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)
Subtract -5/3 from both sides of the equation:
y+5/3x=6
Subtract 6 from both sides:
y+5/3x-6=0
Multiply both sides by 3 to get rid of the fraction:
3y+5x-18=0
Then arrange the numbers to x and y are on one side by itself:
3y+5x=18
And that's your answer!
