Answers
Answer:
The first option: 5/1 x 9/2= 45/2
Step-by-step explanation:
the reciprocal of 2/9 is 9/2 so u basically flip the fraction but the way my teacher taught me was k.i.r. keep it real, it mean keep the first number, inverse which is changing the operation, and reciprocal which is basically flipping the fraction.

Solve this equation y=bd-6, for b
Answers
b = y-6
———
d
Answer: [tex]b = \frac{y+6}{d}[/tex]
Step-by-step explanation: To isolate b, begin by adding 6 to both sides
y=bd-6
y + 6 = bd - 6 +6 This "cancels" 6 on the right leaving
y + 6 = bd Divide both sides by d
(y + 6)/d = bd/d This cancels d on the right leaving
(y + 6)/d = b To neaten this up rewrite (using the equations tool below)
[tex]b = \frac{y+6}{d}[/tex]

If Sara ran 34 km in 300 minutes, what was her speed in km/hr?
Answers
Answer:
6.8 km/hr
Step-by-step explanation:
If Sara ran 34 km in 300 minutes, then, in one hour, she would run
=> 34 : 300
=> ? : 60
=> 300 / 5 : 34 / 5
=> 60 : 6.8
So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

let's see these by examples
A,a‒b is a positive, ‒x‒x=‒2x (the answer is negative) so this is wrong
B,b‒a is a positive, x‒(‒x)=x+x=2x (the answer is positive)so this is correct answer
C,b+(‒a) is a negative,x+‒(‒x)=x‒(‒x)=x+x=2x(the answer is positive)so this is also wrong

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?
12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12
Answers
Answer:
Your answer would be C.
Step-by-step explanation:
The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.
As we know,
The distance = speed x time
Speed is constant
distance ∝ time
3/4 ∝ 12
1 ∝ x
Here x is the distance traveled each minute
3/4 = 12/x
Or
x = 12/(3/4)
1/4 = 4/x
x = 16 miles
Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.
Answers
Step-by-step explanation:
y-b=m(x-a)
y--10=1/6(x--6)
y+10=1/6(x+6)
6y+60=1(x+6)
6y+60=1x+6
6y=1x-54
y=1/6x-54/6
y=1/6x-9
The equation of line is y= 1/6x - 9.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
slope= 1/6
and, passes through (−6,−10)
Now, using slope intercept form
y- a =m (x- b)
y - (-10)= 1/6(x -(-6))
y + 10= 1/6( x + 6)
y + 10 = 1/6x + 1
y= 1/6x - 9
Hence, the equation of line is y= 1/6x - 9.

Answer:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
