### The sum of two numbers is 73. Find the numbers if one number is 15 less than three times the other.

The sum of two numbers is 73. Find the numbers if one number is 15 less than three times the other. x + y = 73 (x-15) = 3y  ------> x = 3y + 15 Substitute (3y + 15) + y = 73 Collect like terms 3y + y = 73 -15 ------> 4y = 58 Divide by 4 to isolate y 4y/4 = 58/4 ------------> y = 14.5 Substitute into given equation x + y = 73 x + 14.5 = 73 ---------------> x = 73 - 14.5 -------> x = 58.5 Thus y = 14.5 and x = 58.5

### 1. Set up the following word problem as an equation and solve. Then write your answer as a complete sentence. The ratio of two numbers is 3 to 5. Their sum is 136. Find the two numbers.

Let the 2 numbers be A and B. A/B=3/5; A+B=136. So B=136-A and we can substitute B in the other equation: A/(136-A)=3/5. Cross-multiply: 5A=3(136-A)=408-3A. 8A=408, A=408/8=51. B=136-51=85. Check the answer: A/B=51/85=3/5.  In words: This is a problem with two unknowns, A and B, and two equations. We use one equation to write one unknown in terms of the other (B is 136 less A), then we substitute for that unknown in the other equation to give A divided by (136 minus A). That gives us one equation and one unknown, A, where the quotient is equal to three fifths. By cross-multiplying to get rid of the fraction, we arrive at five times A is equal to 3 times B which is known to be 136 less A. Now we collect the A terms together to give 8 times A equal to the product of 3 and 136, that is 408. From this we simply divide 408 by 8 to get A equal to 51, then, by subtracting this value from 136 we get B equal to 85. 51 is 3 times 17 and 85 is 5 times 17 so the quotient is three fifths.

### the sum of two numbers is 7.2. the second number is 9.6 less than three times the first. what are the numbers?

Let the numbers be a and b and let b be the second number, so b=3a-9.6 and a+b=7.2, and b=7.2-a. Substitute this in the other equation: 7.2-a=3a-9.6; 4a=7.2+9.6=16.8, so a=16.8/4=4.2. Therefore b=7.2-4.2=3. Check these values for a and b: b=3a-9.6: 3=3*4.2-9.6=12.6-9.6=3. Correct!

### a two digit number in base ten is equal to 5 times the sum of the digits. it is 9 less than the number formed when the digits are interchanged. find the number

a two digit number in base ten is equal to 5 times the sum of the digits. it is 9 less than the number formed when the digits are interchanged. find the number Let the two digits be a and b, such that the number n = ab, meaning n = 10a + b, then n = 5(a + b)        (a two digit number in base ten is equal to 5 times the sum of the digits) n = (10b + a) - 9      (it is 9 less than the number formed when the digits are interchanged.) Our three equations then are, n = 10a + b     ------------------------ (1) n = 5a + 5b     ------------------------ (2) n = a + 10b - 9    --------------------- (3) 2*(2) - (1), 5*(3) - (2) n = 9b 4n = 45b - 45 substituting for n = 9b, 36b = 45b - 45 9b = 45 b = 5, a = 4 ​Ans: number is n = 45

### The sum of two numbers is 84 but one number is three times the other so what are the numbers?

1.....x+y=84 2....y=3x so x+3x=84 4x=84 x=84/4 x=21 y=36

### need perimeter & area..help

I answered this question a few days ago, and at that time the dimensions of the water cases were accidentally given in feet instead of inches. I can see that's been coorected now. I'll go over the solution again, and give some answers on the perimeter and area. First, the volume of a case: 10.2*15.1*8.3=1,278.366cu in=0.74cu ft (approx). Each crate has three dimensions, but the way to lay out the crates to circumscribe the earth with the minimum number of crates is by their lengths. 2.6*10^9 (2.6 billion) laid lengthwise is 3.926*10^10 inches=619,633.8 miles=24.88 equators approx. The volume of that number of cases is 2.6*10^9*1,278.366=3.32375*10^12cu in=1.92347 billion cu ft=0.01307 cu miles. The perimeter of the cases if laid in a long line with the bottles upright would be 2*(3.926*10^10+8.3)in=7.852*10^10in=1,239,267.7 miles approx (the case width is so small in comparison the length of all those crates can be ignored). The surface area would be the sum of the areas of the three visible sides. We can ignore the areas of the exposed ends of the first and last cases compared to the rest of the surface areas. Total exposed surface areas: 2.6*10^9(2*15.1*10.2+15.1*8.3)=2.93*10^21 sq in=2.034*10^19 sq ft=7.30*10^11 sq miles.

### 10-5+4+1-10+5-2=10?

Assuming that addition and subtraction are the only allowable operations, we can see that the equality cannot be realised, because on the left-hand side there are an even number of even numbers and an odd number of odd numbers. No combination of addition and subtraction can produce an even number. So if brackets are used to group the operands on the left, the result will nevertheless be an odd number, and the right-hand side is even. The next plan is to change the base of the numbers to the lowest odd number. The largest digit is 5. The nearest odd number to 5 is 7. Therefore 10 represents the decimal number 7. So to base 7 we have 5 odd numbers and two even numbers. The result will therefore be odd. But this time the right-hand side is odd, because 10 represents the number 7. The sum becomes 7-5+4+1-7+5-2=7, which is still not correct. But if we insert brackets to group some of the numbers together we can write: 7-(5+4+1-7)+5-2=7. This is an exact equation. The three 7's can now be replaced by 10 and the equation interpreted by calculating in base 7 instead of in decimal.
