-6+k÷5=-9 how do we work this out

Mathematics
1 answer:
Step2247 [10]3 years ago

First you have to multiply both sides by -5 which means you will multiply -5 by 6, -5 by k/5, and -5 by 9... So it should look like: -5×6+-5×k/5=-5+9.. after that.. it should look like -40+k=-45.. because the 5's in k/5 cancel out.. so then it should now look like k=-45+30... you subtract.. and k=-15

Karleigh walks 5/8 mile to school every day . How far does she walk to school in 5 days
ziro4ka [17]

Hello, thanks for using Brainly!

First, our equation is: 5/8 x 5 = 25/8.

Our first step is to simplify.

When you simplify you get 3 1/8.

This is another way you can get it: (Multiply across. )

Number of the miles = \frac{5}{8} 5 = \frac{25}{8} = 3\frac{1}{8}

Enjoy your day.

The fuel consumption rate of 10 vehicles is sampled. The rates, measured in miles per gallon, are 32, 24, 14, 34, 26, 27, 31, 16
blondinia [14]
The best estimate of the population mean is the sample mean

first calculate the sum of all samples:
32+24+14+34+26+27+31+16+18+26=248
then divide by the amount of samples to get the samples mean: 248/10=24.8 miles per gallon

Identify an equation in slope-intercept form for the line parallel to y = 5x + 2
Elanso [62]

Answer:

D. y = 5x + 29

Step-by-step explanation:

To write an equation of a line in slope-intercept form, we need to find the slope and the y-intercept.

The equation of a line is y=mx + b.

x and y are the coordinates of any point on a line.

m is the slope.

b is the y-intercept.

Lines are parallel to each other when they have the same slope. A line parallel to y = 5x + 2 would also have the slope 5.

m = 5

Since we have a point on the line, (-6, -1) and the slope, 5, there is only one missing variable, b, the y-intercept.

Substitute the known information into the equation and isolate b.

y = mx + b

-1 = 5(-6) + b  <=Simplify by solving 5 X -6

-1 = -30 + b

-1 + 30 = -30 + 30 + b  <= Add 30 to both sides to isolate b

29 = b

b = 29  <= Standard formatting puts the variable on the left side

Put the m and b values into the equation of a line to solve:

y = mx + b

y = 5x + 29
