Answer:

both methods are correct

Step-by-step explanation:

Given

7(x + 4) = 49 ( divide both sides by 7 )

x + 4 = 7 ( subtract 4 from both sides )

x = 3

---------------------------------------------------------

Given

7(x + 4) = 49 ← distribute parenthesis by 7

7x + 28 = 49 ( subtract 28 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

As shown both methods are equally valid

What is the parallel to 2x-3y=6 and passing through(-3,1) ...?

seraphim [82]

Parallel lines have equal slopes.

$2x-3y=6
\\-3y=-2x+6
\\
\\y= \frac{2}{3} x-2
\\
\\m= \frac{2}{3}
\\
\\(-3,1) \Rightarrow x_1=-3,y_1=1
\\
\\y-y_1=m(x-x_1)
\\
\\y-1=\frac{2}{3}(x-(-3))
\\
\\y-1=\frac{2}{3}(x+3)
\\
\\y-1=\frac{2}{3}x+2
\\
\\3y-3=2x+6
\\
\\2x-3y+9=0$

How do you turn 28/15 into a mixed number

Bond [772]

$\frac{28}{15} = \frac{15 + 13}{15} = \frac{15}{15} + \frac{13}{15} = 1 + \frac{13}{15} = 1 \frac{13}{15}$

Answer:

Do you have options.

If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada wal

Setler [38]

<u>Answer:</u>

The Time taken by Elena and Jade to meet up is 2.5 hours

<u>Explanation:</u>

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.
