Kara and Ian went shopping for apples, a, and bananas, b. Kara bought 6 apples and 5 bananas for $4.54. Ian bought 3 apples and 7 bananas for $3.17. Their purchases can be modeled by the system of equations below. 6a+5b=4.54
3a+7b=3.17

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

2 1/2 feet
