It will take Wanda and Miranda 0.375 hours to be 9 miles apart

Wanda's speed = 6 miles per hour

Miranda's speed = 30 miles per hour

Distance = Speed x time

Find the distance covered by Wanda in t hours

D_{wanda} = 6t

Find the distance covered by Miranda in t hours

D_{miranda} = 30t

Difference in the distances covered

D_{miranda} - D_{wanda} = 30t-6t\\\\D_{miranda} - D_{wanda} = 24t

The difference in their distance is 9 miles

9 = 24t

To find the time, divide both sides by 9

\frac{9}{24} = \frac{24}{24}t\\\\t =   \frac{9}{24}\\\\t = 0.375

It will take Wanda and Miranda 0.375 hours to be 9 miles apart

Write the equation of the line through each point.
Leya [2.2K]

Answer:

The equation would be y = -1/3x + 4

Step-by-step explanation:

The first step to finding this equation needs to be solving the first equation for y so that we can find the slope.

-3x + y = 1

y = 3x + 1

Now that we have the slope of 3, we know the slope of a perpendicular line would be -1/3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.

y - y1 = m(x - x1)

y - 2 = -1/3(x - 6)

y - 2 = -1/3x + 2

y = -1/3x + 4

Bryce tried to solve an equation step by step.
Aloiza [94]

$c=\frac{1}{3}

Solution:

Given equation is \frac{8}{3}=3c+\frac{5}{3}.

To solve the equation by step by step.

Step 1: Given

$\frac{8}{3}=3c+\frac{5}{3}$

Step 2: Combine like terms together.

Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

$\frac{8}{3}-\frac{5}{3}=3c$

Step 3: Subtract the fractions in the left side.

$\frac{3}{3}=3c$

⇒ 1=3c$

Step 4: Divide both side of the equation by 3, we get

$\frac{1}{3} =\frac{3c}{3}$

$\frac{1}{3} =c$

Hence, the answer is c=\frac{1}{3}.

Solve for x when, 8x-12=4x
barxatty [35]

Answer:

x=3

Step-by-step explanation:

8x - 12 = 4x add 12 to both sides you get 8x=4x+12 subtract 4x on both sides then you get 4x=12 divide 4x on both sides and x = 3 Hope helps!!

8x-12=4x

+12    +12

__________

8x=4x+12

-4x   -4x

_______-

4x=12

÷4  ÷4

______

x=3

Hope helps :3

WORTH 10 POINTS! 1)susan can type 4 pages of text in 10 minutes.Assuming she types at a constant rate,write the linear equation
Minchanka [31]
1) pages per minute is the rate. the rate is the slope pages/minutes = .4
y=.4x or y=2/5(x)
2)birdhouses per day is the slope. = .6
y=.6x or y=3/5(x)
3) miles per hour is the slope. 500/8=62.5
y=62.5x
4) square feet per minute is the slope. 40/9 =4.444444444
y=4.4444444444x or y=40/9(x)
5)miles per minutes is the rate. 5/41 is the slope. 
y=5/41(x)
6) the rate is square feet per minute. 450/30=15
y=15x
