Answer:
45 meals.
Step-by-step explanation:
Each meal takes up 2/3 pounds. To find the answer, divide how much Rita bought, 30, by how much is consumed each meal.
30/(2/3)=45
Ali must wear a totally ginormous shirt !
Answer:
x=-1, y=-5
Step-by-step explanation:
To solve these simultaneously using elimination
-4x-2y=14 ....(I)
-10x+7y=-25 ......(ii)
The first step is to ensure that the coefficients of one of the variables(x or y) are the same.
This is done by multiplying with an appropriate number.
Let's say we want to eliminate y in the equations above,
Multiply equation (I) all through by 7 to get:
-28x-14y=98
Multiply equation (II) all through by 2 to get:
-20x+14y=-50
-28x-14y=98
-20x+14y=-50
Since the coefficient of y are the same (14), we can now eliminate.
We add the two equations because 14 has different Signs.
-48x=48
x=-1
Substitute x=-1 in equation (I) to get y.
-4x-2y=14
-4(-1)-2y=14
4-2y=14
-2y=14-4
-2y=10
y=-5
Therefore x=-1, y=-5
Um I’m not to sure sorry maybe someone else can help! Have a nice day! 5•8=40 remember that!
Hello!
lets solve your equation step by step, and with multiple solutions.
the first way to solve it is by simply adding the hours and the minutes together, then combine them.
8+3=11
12+15=27
you get 11 hours & 27 minutes
_____________________________________________________________
for the second one, we will be using minutes only, and there are 60 minutes in an hour
the second way to solve it is:
8*60=480
3*60=180
480+12+180+15=687
I hope this helps, and have a nice day.
