A=(1/2)(h)(B+b)
(6)=(1/2)(h)((2)+(1))
12=h(3)
h=4
Answer: h=4
Answer:
20 = 4n
n = 5
Step-by-step explanation:
Given that :
Number of gifts Keiko wrapped = 20
Let number of gifts wrapped by Henry = n
Keiko wrapped 4 times as many gifts as Henry
Hence,
20 = 4n
The equation that relates the number of gifts wrapped is :
20 = 4n
To obtain n ;
Divide both sides by 4 to isolate n
20/ 4 = 4n / 4
5 = n
Hence,
n = 5
Answer:
6 liters
Step-by-step explanation:
Given:
Renata's recipe for her famous Kale 'n' Clam Quencher calls for kale juice and clam juice in a 3:1 ratio.
If Renata pours 18 liters of fresh kale juice, how many liters of clam juice should she add to maintain this ratio?
Solution:
Ratio to be maintain by using kale juice and clam juice = 3 : 1 ( given)
Renata pours fresh kale juice = 18 liters
We have to calculate quantity of clam juice should be added to maintain this ratio:-
Let quantity of clam juice should be added = ![x](https://tex.z-dn.net/?f=x)
<u>Ratio to be maintain : : quantity of kale juice : quantity of clam juice</u>
![3 : 1=18:x\\ \\ \frac{3}{1} =\frac{18}{x} \\ \\](https://tex.z-dn.net/?f=3%20%3A%201%3D18%3Ax%5C%5C%20%5C%5C%20%5Cfrac%7B3%7D%7B1%7D%20%3D%5Cfrac%7B18%7D%7Bx%7D%20%5C%5C%20%5C%5C)
By cross multiplication:
![3x=18](https://tex.z-dn.net/?f=3x%3D18)
By dividing both sides by 3
![x=6\ liters](https://tex.z-dn.net/?f=x%3D6%5C%20liters)
Thus, 6 liters of clam juice should she add.
4, then 13. Since the 4 is positive it doesn’t need to change, and 13 is negative therefore it will be positive
