Step-by-step explanation:
Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230
13) divide 71.5 by 5.5 to find the answer for u.
14) find the common denominator then divide like in the last one
15) multiply 11 by 44 to find t
16) multiply 14 by 8.3 to find b
17) multiply 3 by 15 to find x
18) divide 23.4 by 7.8 to find x
