Answer:

an apple costs 0.24 and a pear costs 0.28

Step-by-step explanation:

      3a + 4p = 1.84                                 3a + 4p = 1.84

     -5a + 2p = 1.76   m(-2)                 -10a - 4p = -3.52

        3a + 4p = 1.84

 +   -10a - 4p = -3.52

       -7a          = -1.68

           a         = -1.68/-7

           a        =  0.24

       3a + 4p = 1.84

       3(0.24) + 4p = 1.84

       0.72  + 4p = 1.84

                   4p = 1.84 - 0.72

                    4p = 1.12

                      p = 0.28

The cost of an apple is £0.24 and the cost of pear is £0.28

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let a represent the cost of one apple and p represent the cost of one pear.

Then the system of equation will be;

     3a + 4p = 1.84                                

    -5a + 2p = 1.76   m(-2)                

-10a - 4p = -3.52

Solving both the equation;

-7a   = -1.68

a   = -1.68/-7

a   =  0.24

For solving p;

3a + 4p = 1.84

3(0.24) + 4p = 1.84

0.72  + 4p = 1.84

4p = 1.84 - 0.72

4p = 1.12

p = 0.28

Hence, the cost of an apple is £0.24 and the cost of pear is £0.28

Step-by-step explanation:

4 cups of water would need 16 tablespoons of olive oil.

Each cup of water uses 2 2/3  cups of flour, while each cup of flour he uses, Amir needs to use 1 1/2  tablespoons of olive oil. Hence for 4 cups of water:

4 cups of water = 2 2/3  cups of flour × 4 cups = 32/3 cups of flour

32/3 cups of flour = 1 1/2  tablespoons of olive oil * 32/3 = 16 tablespoons of olive oil

4 cups of water would need 16 tablespoons of olive oil.
