When 40% of a number is added to the number, the result is 168.
What is the number?
Answer:
-100.8
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
Let's call the number x. 40% of that number is 4/10x, or 0.4x
So x + 0.4x = 168
1.4x = 168
1.Divide each side by 1.4
x = 120
The number is 120
A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8
y = -6x + 20
Explain why the work is not correct.

Answer:
I believe the answer is p = -7/5
Step-by-step explanation:
Here's the equation and the workthru of my logic:
-5 (p + 3/5) = -4
Divide both sides by -5 to remove the -5 from the left side of the equation,
p + 3/5 = -4/5,
Subtract 3/5 from both sides to solve for p,
p = -4/5-3/5
p = -7/5
Solution is -7/5
Hope this helps.
Good luck!

1.) An American tourist changed US $925 into Trinidad and Tobago currency at the exchange rate US $1.00= TT $ 4.25
a.) Calculate the amount of TT dollars he received.
b.) The tourist spent TT $ 1806.25 and changed the remaining TT dollars into American currency at the same exchange rate. Calculate the amount of US dollars he received.
2.) A bank gives two dollars and seventy-five cents in Eastern Caribbean currency (EC $2.75) for one United states dollar (US$ 1.00).
Given that 1% tax is charged on all foreign exchange transaction, calculate the amount, in E.C. currency, which a tourist receives in exchange for US $1200.00.
3.) Given that TT $1.00= EC $ 1.12
And TT $ 4.25= US $1.00
Convert (a.) TT $55.00 to EC $
(b.) EC $850.00 to US $
4.) a.) A tourist changed US $ 1200 to Trinidad and Tobago currency. Calculate the amount she received at the exchange rate US $1.00= TT $2.40
b.) Calculate the amount she would receive at the exchange rate US $1.00=TT $ 5.76
Step-by-step explanation:
1)a) 925×4.25=3931,25
b) 1806.25:4.25=425
I don't know second one.
3)a 55×1.12=61.6

Explain how you calculate the constant of variation.
Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

Answer:
Step-by-step explanation:
∠1 , ∠4 and ∠8
A. 35
B. 85
C. 50
D. 25
Answer: B
Step-by-step explanation:
Use the exterior angle theorem, which states that the exterior angle of a triangle is equal to the sum of the two remote interior angles.
In this case: 120-x= 10+x+60
Simplifying it by combining like terms: 120-x=70+x
Solving by isolating the variable: 50= 2x, x=25
Now use what we know, which is that angle A is 35 degrees, and angle B is 60, to find out that the correct answer is B, 85 degrees.

Mr. Jeff has a budget of $150 to spend on music books. The cost of the books is $12. What is the maximum number of books can he buy?
Answer:
12 books
Step-by-step explanation:
if each book costs 12 dollars, and the budget is 150, then all you need to do is divide 150 by 12, in which case you will get 12.5.
you aren't able to go and by twelve and a half books, so you round down to twelve, and you will have six dollars to spare.
