Answer:
30.5 Weeks
Step-by-step explanation:
The phone costs $930, and he already has $320 saved in his bank account so subtract 320 from 930. You will get 610. Then, you take 610 and divide it by 20 because he earns $20 a week. I hope this helped.
Part A: 5 is the coefficient, w is the variable, 50 is the constant
Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140
Part C: the constant,50,would change and become 85. Hope this helps :)
Answer:
440
Step-by-step explanation:
55x8. 8x5=40 carry the 4. 8x5=40+4=44 so it is 440
Step-by-step explanation: If I replace the variables with the numbers, the equation would be: 36+(4x2x3)/36-(4x2x3). First, solve the numbers in the parentheses. Both numbers in the parenthesis equals 24 because 4x2 is 8 and 8x3 is 24. Then, 36+24/36-24. PEMDAS, so 24/36 is 0.666666666667. Then 36+0.666666666667 is 36.666666666667. Next, 36.666666666667 minus 24 is 12.666666666667.
