Answer: The cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
Step-by-step explanation:
Let x be the cost of one sandwich and y be the cost of one cup of coffee.
By considering the given situation, we have the following equations :-
Multiply 2 on both sides of equation (2) , we get
Subtract equation (1) from equation (3), we get
Put value of y in (1), we get
Hence, the cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
So first take triple 3 which would be 3+3+3 or 3x3.
Then take double 8 which would be 8+8 or 8x2.
So all you need to do is write it in the associative property.
So it would look like this:
(3x3)+(8x2)= 25
9 + 16
Because 3x3 is 9 and 8x2 is 16 so you just need to add them to get the product.
Both number have filled circle meaning that t does contain -3 and 4.
t > equal to -3
t < equal to 4
Answer: B
This is an expression, meaning it doesn't have an equal sign. therefore it cannot be solved, only reduced into its simplest form. to do so, you must change both fractions into a common denominator. in this case its 12. so you have 4/12 and 15/12, or 1 3/12. Together, this adds to be 1 and 7/12.
your answer in simplest form is 1 7/12 + a
Answer:
x = 634.3563415.
Step-by-step explanation:
0.25[10.25x-0.21(10.25)]=1675
0.25[10.25x-2.1525]=1675
2.5625x - 0.538125 = 1675
2.5625x = 1675 + 0.538125
x = (1675 + 0.538125) / 2.5625
x = 634.3563415
