Answer:
So the answer is 12 and 31.
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
Answer:
1 and 11/20
Step-by-step explanation:
3/4 + 4/5
= 15/20 + 16/20
= 31/20
= 1 and 11/20
Hope this helped!
You can buy 15 ink cartridges from 180 dollars.
Step-by-step explanation:
Given,
Amount you have = 180 dollars
Cost of one cartridge of ink = 12 dollars
We will divide the total amount with the cost of one cartridge of ink to find the number of ink cartridges that can be bought.
Number of ink cartridges =
Number of ink cartridges = 15
You can buy 15 ink cartridges from 180 dollars.
