Answer:
<u>Let x the the number of cans of tomatoes and </u>
<u> 32 - x be the number of cans of corn</u>
From the given that the total cost in buying all 32 cans of vegetables is $18 and the costs of each can of vegetables, we generate the equation,
18 = 0.80x + 0.40(32 - x)
Solving for x from the equation gives x = 13. Alex bought 32 - x cans of corn with a numerical value of 19. Thus, Alex bought<em><u> 19 cans of corn</u></em>.
Step-by-step explanation:
11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.
Answer:
can we are friend in brainly please give me your intro
First take out the common factor
y(3-z)=2z
Then divide both side by 3-z
y=2z/3-z
Done
