Answer:
1,542.45
Step-by-step explanation:
Rate tax 13% => Total cost after tax is the sum of total cost before tax and cost of tax
The value of cost of tax: 1,365x13%=177.45
So, total cost: 1,365+177.45=1,542.45
Answer:
-33
Step-by-step explanation:
2/3 (x + 6) = - 18
Multiply by 3/2 on each side
3/2 *2/3 (x + 6) = - 18*3/2
x+6 = -27
Subtract 6 from each side
x+6-6 = -27-6
x = -33
Answer:
A) 8m-10n
B) 19r - 19s
C) 12 - 28g + 8f
Step-by-step explanation:
To write the equation in standard form:
- Distribute into any parenthesis
- Combine the like terms
- Write in descending order
A). 4 (8m-7n) +6 (3n-4m)
32m - 28n + 18n -24m
8m -10n
B). 9 (r-s) + 5 (2r-2s)
9r-9s+10r-10s
19r-19s
C). 12 (1-3g)+8 (g+f)
12 - 36g + 8g + 8f
12 - 28g + 8f
Assuming that you are talking about a rectangular prism and assuming the two sides are 4x5 inches than its as simple as 4x5x6
4x5=20(base)
20x6=120 cubic inches is ur answer
Lets x is the amount of money Paul spent
y is the amount of money John spent
<span>Henry spent 3 times as much as paul = 3x
so
</span>John and paul spent $45 altogether: <span>x + y = 45
</span> john and henty spent $65 altogether: 3x+y = 65
solve the equations
3x+y = 65
x + y = 45
---------------subtract
2x = 20
x = 10
x + y = 45
y = 45 - x
y = 45 - 10
y = 35
3x = 3(10) = 30
so
Paul spent $10 (x)
John spent $ 35 (y)
Henry spent $30 (3x)
answer: John spent $ 35
double check:
$ 35 + $ 10 = $45 (<span>John and Paul spent $45 altogether)
</span>$ 35 + $30 = $65 (<span> John and Henry spent $65 altogether)</span>
