Answer:
The two numbers are 7 and 11.
[711? Is this an ad? ← :)]
Step-by-step explanation:
Let A and B stand for the two numbers.
We are told that:
1) A+B=18, and
2) A-B=4
Take the first expression and rearrange to isolate A:
A+B=18
A=18-B
Use this in the second expression:
(18-B)-B=4
-2B = -14
B = 7
From (1) we find A:
A+B=18
A+7=18
A= 11
If A=11, then B=7 (from A+B=18)
CHECK:
Does A+B=18?
11 + 7 = 18? YES
Does A-B=4?
11 - 7 = 4? YES

Step-by-step explanation:
.a. Find the LCM of the 45 and 70
Answer:
630.
Find the Prime factorization of 45, 3 x 3 x 5
Find the prime factorization of 70, 2 x 5 x7
Multiply each factor the greater number of times it occurs.
You get 630.
LCM of 45 and 70 :
= 45 ÷ 5 , 70 ÷ 5 ( Both the numbers are being divided by 5 ; which is their smallest common factor )
= 14 , 9
= 14 ÷ 14 , 9 ( We are dividing 14 by 14 as both 9 and 14 dont have have a common factor )
= 1 , 9
= 1 , 9 ÷ 3 ( 9 is being divided by 3 )
= 1 , 3
= 1 , 3 ÷ 3 ( 3 is being divided by 3 )
= 1 , 1
LCM of 45 and 70 = 5 × 14 × 3 × 3
LCM of 45 and 70 = 630
Therefore , the LCM of the 45 and 70 = 630 .
Willie won 125 lollipops playing hoops at
his school's game night. Later, he gave
four to each of his friends. He only has 1
remaining. How many friends does he
have?
Answer:
Step-by-step explanation:
Easiest way to do this is to work backwards.
If Willie only has 1 remaining lollipop, this means that he must've given a total of 124 lollipops to his friends. (125 - 1 = 124)
Then we know he gave 4 lollipops to each friend. So all you need to do is divide the total number of lollipops he gave to his friends (124) by how many he gave to each friend.
Number of friends = Total number of lollipops given to friends / Number of lollipops given to each friend.
Number of friends = [tex]\frac{124}{4} = ?[/tex]

Write three factors of 24 which have a sum of more than 37 and less than 40
Answer:
24, 12, 2
Step-by-step explanation:
24, 12, and 2 are all factors of 24.
24+12+2=38
37<38<40
the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.
To find three factors of 24 with a sum between 37 and 40, we can start by listing the factors of 24:
1, 2, 3, 4, 6, 8, 12, 24
Next, we'll try different combinations of these factors to see if any three of them add up to a sum between 37 and 40:
1 + 2 + 24 = 27 (not within the desired range)
1 + 3 + 24 = 28 (not within the desired range)
1 + 4 + 24 = 29 (not within the desired range)
1 + 6 + 24 = 31 (not within the desired range)
1 + 8 + 24 = 33 (not within the desired range)
1 + 12 + 24 = 37 (not within the desired range)
2 + 3 + 24 = 29 (not within the desired range)
2 + 4 + 24 = 30 (not within the desired range)
2 + 6 + 24 = 32 (not within the desired range)
2 + 8 + 24 = 34 (not within the desired range)
2 + 12 + 24 = 38 (within the desired range)
3 + 4 + 24 = 31 (not within the desired range)
3 + 6 + 24 = 33 (not within the desired range)
3 + 8 + 24 = 35 (not within the desired range)
3 + 12 + 24 = 39 (within the desired range)
4 + 6 + 24 = 34 (not within the desired range)
4 + 8 + 24 = 36 (within the desired range)
4 + 12 + 24 = 40 (not within the desired range)
6 + 8 + 24 = 38 (within the desired range)
6 + 12 + 24 = 42 (not within the desired range)
8 + 12 + 24 = 44 (not within the desired range)
Therefore, the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.

if 2x – 1 is a factor of 16x4
24x3 + 2x + f, find f.
Answer:
f = -5
Step-by-step explanation:
If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.
If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.
2x - 1 = 0
2x = 1
x = 1/2
Hence
f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f
= 16(1/16) + 24(1/8) + 1 + f
= 1 + 3 + 1 + f
= 5+ f
f = -5
