Option A
The system of equations are x + y = 40 and 10x + 7y = 360
<em><u>Solution:</u></em>
Let pounds of expensive coffee beans be x
Let pounds of cheaper coffee bean be y
Cost of 1 pound of expensive coffee bean = $ 10
Cost of 1 pound of cheaper coffee bean = $ 7
<em><u>The shop also sells a 40 pound mixture of the two kinds of coffee beans</u></em>
pounds of expensive coffee beans + pounds of cheaper coffee bean = 40
x + y = 40 ------ eqn 1
<em><u>The shop also sells a 40 pound mixture of the two kinds of coffee beans for $9 per pound</u></em>
pounds of expensive coffee beans x Cost of 1 pound of expensive coffee bean + pounds of cheaper coffee bean x Cost of 1 pound of cheaper coffee bean = 40 pound mixture x $ 9
10x + 7y = 360 --------- eqn 2
Thus the system of equations are x + y = 40 and 10x + 7y = 360
Thus option A is correct
Fred's age is 13 years
Let
Fred's age = x
Jack's age = 2x + 4
After 8 years:
- Fred's age = x + 8
- Jack's age = 2x + 4 + 8
= 2x + 12
Sum of their ages = Fred's age + Jack's age
59 = (x + 8) + (2x + 12)
59 = x + 8 + 2x + 12
59 = 3x + 20
59 - 20 = 3x
39 = 3x
x = 39/3
x = 13 years
Therefore, Fred's age = 13 years

Step-by-step explanation:
This sequence es the sum of 3
5+3 =8
8+3 = 11

Answer:
Trinity can withdraw $25 from her bank account for 13 weeks.
Step-by-step explanation:
If she wants to have at least $200 by the end of summer you need to subtract that much from what she has now. Which would be $325.38. Now you have to divide that number into 25, which should give you the number of week that money would last. That number is 13.0152, you don't need all those extra numbers so just use 13. No to check you work multiply 25 and 13. You get 325.
