A)
94 miles

B)
595 miles

C)
632 miles

D)
637 miles
PLS HELP I AM IN A TEST PLS ANSWER CORRECTLY PLS

Answers

I believe it would be 637 miles, if you multiply 245-the distance in miles they travel each day, and multiply it by 2.6 you get 637 miles, so D should be the correct answer! :)

The distance covered in 2.6 days will be 637 miles. The correct option is D.

What is speed?

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that the riders were able to cover about 245 miles per day before they would stop and rest. The trip between San Francisco and Denver takes 2.6 days.

Distance will be calculated by the formula below:-

Distance = Speed x time

Distance = 245 x 2.6

Distance = 637 miles

Therefore,  the distance covered in 2.6 days will be 637 miles. The correct option is D.

Solve for X: 6x+25=1

Answers

6x+25=1

move +25 to the other side

sign changes from +25 to -25

6x+25-25=1-25

6x=1-25

6x=-24

divide both sides by 6 to get x by itself

6x/6=-24/6

x=-4

answer: x=-4

X=-4
Subtract 25 form both sides which would end up as
6x=-24
Then divide 6for both side later which ends ups as
X=-4

Plz help

Answers

Answer:

x = 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-4x + 2 = -22

Step 2: Solve for x

Subtract 2 on both sides:                    -4x = -24Divide -4 on both sides:                       x = 6

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    -4(6) + 2 = -22Multiply:                               -24 + 2 = -22Add:                                     -22 = -22

Here we see that -22 does indeed equal -22.

∴ x = 6 is a solution of the equation.

The line segment joining A(6, 3) to B(–1, –4) is doubled in length by having half its length added to each end. Find the coordinates of the new ends.

Answers

Answer:

(9.5, 6.5) and (-4.5, -7.5)

Step-by-step explanation:

Let the extended points be A' and B' and add the point M as midpoint of AB

Coordinates of M are:

((6 - 1)/2, (3-4)/2) = (2.5, -0.5)

Now point A is midpoint of A'M and point B is midpoint of MB'

Finding the coordinates using midpoint formula:

A' = ((2*6 - 2.5),(2*3 - (-0.5)) = (9.5, 6.5)B' = ((2*(-1) - 2.5), (2*(-4) - (-0.5)) = (-4.5, -7.5)
