You have to do like draw a number line and do the opposite and you'll get your answer and add them together and you'll get 45.5

You could add twelve to -12 which would cancel it out. then add twelve to -44 which would give you -32=8n.
then divide 8n by 8n which cancels it out, then divided -32 by 8n which gives you -4.

The lines represented by the equations 25y
gogolik [260]

Answer:

C: The Same Line

Step-by-step explanation:

So to start we need to first know what makes lines parallel or perpendicular. Two parallel lines will have the same slope, but different y-intercepts because we know they never cross. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is y=mx+b where m is the slope of the line and b is the y-intercept. We can see that neither equation is in this form, so we have to convert it.

Starting with the first, (I assume despite the typo) we have 25y+10x= 200

So we need to isolate the y from everything else.

First, we'll subtract 10x from both sides of the equal sign to get 25y=-10x+200

Second, we'll divide both sides by 25 to get y=-\frac{2}{5} x+8

This means that -\frac{2}{5} is the slope and 8 is the y-intercept of the first line.

Now onto the second we have 5y+2x=40 so we're going to follow the same steps to isolate y.

First, we'll subtract 2x from both sides to get 5y=-2x+40

Second, we'll divide both sides by 5 to get y=-\frac{2}{5}x +8

This means that -\frac{2}{5} is the slope and 8 is the y-intercept of the second line.

Since both of the lines have a slope -\frac{2}{5} we know that they are parallel, so we need to check to check if they're the same by looking at the y-intercept. We can see that 8 is the y-intercept of both lines, so they would be the same line.

A tree that was 30 meters high was broken so that the broken part was 7 times the length of the part that was left
nikitadnepr [17]

Answer:

Broken = 7x

Step-by-step explanation:

Left = x

x(7x) = 30

(7x² = 30)⅐

x² = 4.285

√x² = √4.285

x = 2.07

Left = 2.07 meters

Broken = 7 x 2.07 = 14.49 meters

i hope this is correct!

good luck on ur test!

ANSWER FAST!! TIMED EXAM!!!
den301095 [7]

Answer:

the change in the amount of time is 30 minutes

Step-by-step explanation:

The computation of the change in the amount of time is shown below

= Number of consecutive ways × number of  minutes more each day

= 6 days × 5 minutes

= 30 minutes

Hence, the change in the amount of time is 30 minutes

Therefore the correct option is D.

We simply applied the above formula so that the correct value could come

And, the same is to be considered
