Combine like terms that share a common variable. If a scalar multiple is outside the parentheses, use the distributive property to expand the expression.
15) I cannot read the whole expression.
16) 4n - n = 3n
17) -3x - 9 + 15x = 12x - 9
18) -9k + 8k = -k
19) -16n - 14n = -30n
20) 15n - 19n = -4n
21) - 4 + 7(1 - 3m) = -4 + 7 - 21m = -21m + 3
22) -5n + 3(6 + 7n) = -5n + 18 + 21n = 16n + 18
23) -2n - (9 - 10n) = -2n - 9 +10n = 8n - 9
24) 10 - 5(9n - 9) = 10 - 45n + 45 = -45n + 55
25) 9a + 10(6a - 1) = 9a + 60a - 10 = 69a - 10
26) -9(6m - 3) + 6(1 + 4m) = -54m + 27 + 6 + 24m = -30m + 33
27) -10(1 - 9x) + 6(x - 10) = -10 + 90x + 6x - 60 = 96x - 70
28) 5(-2n + 4) + 2(n + 3) = -10n + 20 + 2n + 6 = -8n + 26
Answer:if your looking for slope intercept it’s y=21/4x-0
Step-by-step explanation:
A = P(1+i/n)^nt
A = Total amount paid
P = Principal amount
i = Annual interest
n = number of payments per year
t = time in years
Substituting the values given,
A = 1800(1+0.032/52)^52*10 = $2,478.59
Interest paid = A - P = 2478.59-1800 = $678.59
Second answer is correct.
Answer:
B. 4d + 50 = 114
Step-by-step explanation:
Given parameters:
Hourly rate = $d/hr
Flat fee = $50
Charge for the 4hrs = $114
Number of hours = 4hrs
To find d;
Total cost = $114;
$114 = Flat fee + (rate per hour x number of hours)
$114 = $50 + 4d
The value of d can be calculate using;
4d + 50 = 114
The value of d is <em>4d + 50 = 114</em>
Depends on what it's rounded to, but in standered math it would be put to .127 because people like 3 decimal spots for some reason
