Let the first number equal x and the second number equal y.
You have:
A) x + y = 89.
B) 4x + y = 155.
First you rearrange equation A to obtain equation C) y = 89 - x
Then substitute C) into B) to obtain equation D) 4x + 89 - x = 155
Solve equation D) for x to obtain x = 22.
Place the value of x in equation C) to obtain y = 67.
Thus your answer is {x = 22, y = 67}.

The second of two numbers is 4 times the first their sum is 45?
This problem asks us to find 2 numbers, n1 and n2, with the following relations between them: * n2 = 4 n1 * n1 + n2 = 45 Substituting the first equation into the second one gives us: * n1 + 4n1 = 45 which gives us * n1 = 9. We can now use this solution to find n2 with the first equation * n2 = 4 n1 = 36 So the first number is 4, the second number is 36.
Find two numbers whose difference is 15 and whose sum is 53?
19 and 34. Let the two numbers be x and y; then: x - y = 15 x + y = 53 Adding the two equations gives: 2x = 68 → x = 34 Substituting for x in the second gives: 34 + y = 53 → y = 19 Checking by substituting for x and y in the first gives: 34 - 19 = 15 as required.
What is next number is series 298 209 129 58 - 4?
The answer can be any number that you like: it is always possible to find a polynomial of order 5 to fit the given numbers and any other number.The lowest degree polynomial that will fit the given numbers is the quadraticUn = (9n2 - 205n + 792)/2 for n = 1, 2, 3, .. . and that gives the next number as -57.The answer can be any number that you like: it is always possible to find a polynomial of order 5 to fit the given numbers and any other number.The lowest degree polynomial that will fit the given numbers is the quadraticUn = (9n2 - 205n + 792)/2 for n = 1, 2, 3, .. . and that gives the next number as -57.The answer can be any number that you like: it is always possible to find a polynomial of order 5 to fit the given numbers and any other number.The lowest degree polynomial that will fit the given numbers is the quadraticUn = (9n2 - 205n + 792)/2 for n = 1, 2, 3, .. . and that gives the next number as -57.The answer can be any number that you like: it is always possible to find a polynomial of order 5 to fit the given numbers and any other number.The lowest degree polynomial that will fit the given numbers is the quadraticUn = (9n2 - 205n + 792)/2 for n = 1, 2, 3, .. . and that gives the next number as -57.
You are thinking of two numbers whose sum is 64 If you double the second and subtract this product from the first the result is -8 What are the two numbers?
Firstly: X + Y = 64 Secondly: X - 2Y = -8 Therefore X = 2Y - 8 Now, we can put that value of X into the first equation and we get 2Y - 8 + Y = 64 Which reduces to 3Y = 72, and that gives Y = 24. So, if X + 24 = 64 then X = 40. Putting that into the second equation we get: 40 - 2(24) = 40 - 48 = -8
How do you determine percentage of growth from one number to another?
You do the following: 1) Divide the second number by the first. This will give you a factor, for example 1.20. 2) Subtract 1 from the result. This gives you the increase as a factor, for example, 0.20. 3) Multiply the result by 100, to convert to a percentage. In this example, 20%.
Which numbers when multiplied by 5 gives an odd numbers?
Every odd number. Multiplying two even numbers gives an even number. Multiplying an odd and an even number gives an even number. Multiplying two odd numbers gives an odd number.
What is 4x30 Binocular?
Binoculars are specified by numbers such as 4×30, the first number gives the magnification of the object and the second number gives the aperture in millimeters. Good binoculars with a large aperture (50 mm or more) are useful at night for astronomy.Read more: binocular
The second of two numbers is 4 times the first their sum is 45?
This problem asks us to find 2 numbers, n1 and n2, with the following relations between them: * n2 = 4 n1 * n1 + n2 = 45 Substituting the first equation into the second one gives us: * n1 + 4n1 = 45 which gives us * n1 = 9. We can now use this solution to find n2 with the first equation * n2 = 4 n1 = 36 So the first number is 4, the second number is 36.
Could you show me examples of a non significant numbers?
No. If I give you a list of non significant numbers, then there will be a first number in the list and it will therefore be a significant number as it's the first one of the list, so I'd have to remove it from the list. This would then leave the second non significant number as the first one in the list which gives it significance, so I'd have to remove it as well. The net result is that I'd have to remove all the numbers from the list of non significant numbers leaving it empty, that is, there are no non significant numbers.
One number is 8 more than twice the second number The sum of the numbers is 123 Find the numbers?
Let a be the first number and b the second number then, (1) a = 8 + 2b and (2) a + b =123 From (2) a = 123 - b substituting for a in (1) gives :- 123 - b = 8 + 2b , 3b = 115, b = 115/3 = 38⅓. and substituting for this in (2) gives :- a + 38⅓ = 123, a = 123 - 38⅓ = 84⅔. So, a = 84⅔ and b = 38⅓
How the elements of isotopes are alike and how they are different?
Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
The sum of 2 numbers is 92 one fifth of the 1st number added to half of the second number is 34?
I suppose you want to know the two numbers?let the two numbers be x and y; then:x + y = 921/5 x + 1/2 y = 34Multiplying the first equation by 5 and the second by 10 gives:5x + 5y = 4602x + 5y = 340Subtracting the new second equation from the new first gives:3x = 120 → x = 40And substituting for x=40 back into the original first equation gives:x + y = 92 → 40 + y = 92 → y = 52Substituting the values of x and y into the original second equation as a check gives:1/5 x + 1/2 y = 1/5 x 40 + 1/2 x 52= 8 + 26= 34 as requiredThe two numbers are 40 and 52.
