No, she is incorrect (in my opinion) i think the answer is :
1/2 m - 4 = 5
4+5 = 9 so
half of 18= 9
so the answer is 18?
Answer:
b/(b+a)
Step-by-step explanation:
(1/a)-(1/b) :[ (b²-a²)/ab²]
first solve :
common denominator ab
(1/a)-(1/b) = (b-a)/ab
[b-a/ab] : [(b²-a²)/ab²]
when divide fraction ( division sign turn to (×) and flip the second fraction(reciprocal):
[b-a/ab] × [ab²/ (b²-a²)]
then simplify : ab²/ab = b
(b-a)×(b/b²-a²)
factorize : b²-a² = (b-a)(b+a)
(b-a)×(b/(b-a)(b+a)) simplify : (b-a)/b-a = 1
[(b-a)(b)]/[(b-a)(b+a)
b/b+a
Answer:
<u>y = -3x + 8</u>
Step-by-step explanation:
<u>Given :-</u>
Point on line = (5, -7)
Slope (m) = -3
<u>To find :-</u>
Equation of line
<u>Solving :-</u>
Using point-slope form of equation,
y - y₁ = m(x - x₁)
y + 7 = -3(x - 5)
y + 7 = -3x + 15
<u>Solution :-</u>
<u>y = -3x + 8</u>
Answer:
6 tenth
Step-by-step explanation:
Place values of numbers are the values such number represents in a given number. Example, we have tens, hundreds units etc.
To obtain the value of 6 in 3.651 we have to find the decimal place equivalent of 6 in the expression.
6 in 3.651 = 6/10
= tenth
Therefore the place value of 6 in 3.651 is the first decimal place which is 6 tenth
Answer:
12 weeks.
Step-by-step explanation:
Amanda starts with $2000 and is getting $150 per week which means that we can make the expression:

The expression is equal to 200 because is the limit where we can arrive to avoid the fee, then the n is the number of weeks that we are looking for:

n=12 weeks
