Answer:
45 is the other whole number.
Step-by-step explanation:
Method I:
Given: 9(6 + 5)
Distribute 9 over 6 and 5. We get:
9 X 6 + 9 X 5 = 54 + 45
⇒ 45 should be added to 54 to arrive at the sum.
Method 2:
Given: 9(6 + 5)
⇒ 9 X 11 [Since, 6 + 5 = 11]
= 99
Therefore, 99 = 54 + a
⇒ a = 99 - 54
⇒ a = 45
Hence, the other number is 45.
Answer:
$360
Step-by-step explanation:
The intial ratio of the sum shared between Khairul, Michael and Ethan is 6 : 4 : 5.
This would be 6x : 4x : 5x
Khairul gives $30 to Michael and $15.
The ratio is. Now;
(6x - 45) : (4x + 30) : (5x + 15)
We are told this is equal to the ratio 7:6:7
Thus;
((6x - 45) + (4x + 30))/(5x + 15) = (7 + 6)/7
(10x - 15)/(5x + 15) = 13/7
Factorize the left hand side;
5(2x - 3)/5(x + 3) = 13/7
5 will cancel out to get;
(2x - 3)/(x + 3) = 13/7
Cross multiply to get;
7(2x - 3) = 13(x + 3)
14x - 21 = 13x + 39
14x - 13x = 39 + 21
x = 60
Amount Khairul had initially was denoted as 6x.
Thus,6x = 5 × 60 = $360
Answer:
Cross products.
Step-by-step explanation:
In the proportion a/b = c/d the products a•d and b•c are usually called cross products.
I’m going to use the second one to explain
-8j + 14 = -2(4j-7)
So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.
