Let's see.
If the smallest number is x, then the largest one is 2x + 9. Then,
x + 2x + 9 = 5x - 3 (we assume that this is true)
3x + 9 = 5x - 3 subtract 5x and 9 to both sides
-2x = -12 divide by -2 to both sides
x = 6
Since x = 6, then 2x + 9 = 2(6) + 9 = 12 + 9 = 21.
check:
6 + 21 = 5(6) - 3 ?
27 = 30 - 3 ?
27 = 27 True
The numbers are: 7 and 13
the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
L = S + 11; 2S + 3(S + 11) = 123, ie 2S + 3S + 33 = 123ie 5S = 90 ie S = 18 and L = 29
If the higher is 3 times the lower, the difference must be twice the lower so the numbers are 8 and 24.
If the order of the pairs of numbers doesn't matter (that is the pairs (1, 11) and (11, 1) are considered the same) then there are 89 such pairs.If the order does matter (that is the pairs (1, 11) and (11, 1) are considered different) then there are 178 such pairs.There must be one number larger than the other.The smaller number must be at least 1, so the larger number must be at least 11.The larger number must be at most 99, so the smaller number must be at most 89.Thus, looking at the smaller numbers, it can be one of the numbers 1 to 89 - a total of 89 possibilities - each of which has a corresponding larger number.Therefore there are 89 combinations of 2 integers from the number 1-99 that have a difference of 10.If however, the order of the integers is important, then the smaller number can be the first number or second number, which means that there are twice as many possible pairs, giving 178 permutations of 2 integers from the numbers 1-99 that have a difference of 10.
13 and 6
The numbers are: 7 and 13
There are two consecutive odd numbers such that five times the smaller plus twice the greater is 25. What is the smaller number?
The numbers are: 48+22 = 70
8 and 15.
16.5
Smaller number = x Larger number = 2x x+2x=18. 3x=18 x=6 The numbers are 6 and 12.
18 and 38
18 and 38
Area of a rectangle is Base(B) times Height(H).Area of smaller rectangle is BH.Area of larger rectangle is 2BH.Area of larger rectangle is twice as large as the smaller rectangle.
If the larger number can be anything more than twice the smaller number, then the two numbers can be:1 + 45 = 463 + 43 = 465 + 41 = 467 + 39 = 469 + 37 = 4611 + 35 = 4613 + 33 = 4615 + 31 = 46
One number is 7, the other is 14. 7 + 14 = 21 4(7) = 2(14)
