Step-by-step explanation:

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.

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.

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]

Answer:

non proportional

Step-by-step explanation:

Answer:

non proportional

Step-by-step explanation:

proportional graph is a straight line that always goes through the origin. A non-proportional graph is a straight line that does not go through the origin.

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.

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.

because a=7 and b=5

brainliest?

Answer:

B,b‒a is a positive.

Step-by-step explanation:

if a=‒x x=rational number

b=x

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

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.

Step-by-step explanation:

Answer:

[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]
