5x - 3y = 10
x + y = 7......multiply by -5
------------------
5x - 3y = 10
-5x - 5y = -35 (result of multiplying by -5)
------------------add
-8y = -25
y = 25/8
x + y = 7
x + 25/8 = 7
x = 7 - 25/8
x = 56/8 - 25/8
x = 31/8
solution is (31/8 , 25/8)
Answer:
n = 24
Step-by-step explanation:
16+ n/4 =22
Subtract 16 from each side
16-16+ n/4 =22-16
n/4 = 6
Multiply each side by 4
n/4*4 = 6*4
n = 24
First of 3/7 of a week is 3 days because there are 7 days in a week e out of seven so you get it?
1. The question is asking you how much barrels of raisins is used in three days but first you need to find out how much they use in 1 day (this is how I would do it) so turn all the fractions into a decimal
4/9 = 0.4444...
6/5= 1.20
3/7= 0.43
So now you got your decimals
2. Multiply 0.4444 by 1.20 now you got how much you get a day for cosmos bakery which is 0.53
3. Now go back to the 3/7 of a week which is 3 days and now you need to multiply 0.53 by 3 and you will get your answer
ANSWER!
1.59 a day for cosmos bakery
I HOPE THIS HELPED YOU TO SOLVE THIS PROBLEM AND SOME FUTURE ONES!
We have the following function:

So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for

as shown in the Figure. This is also true because of

where

must be greater (or equal) than zero.
Second. The range of the function are the values of

.
Third. If

creases then

always creases, too.
If n = $3 then plug it in
$10 + ($6-$3)
$6-$3 = $3
$10 + $3 = $13
