Match each equation to equivalent equation. -4x+3y=20 -6x-2y=10. 2x +5y=18

Mathematics
1 answer:
alex41 [277]2 years ago
6 0

Answer:

4x + 10y = 36  ≡  to 2x + 5y = 18

As you can see, the the coefficients on the first one are double those in the second.

12x - 9y = -60  ≡  to -4x + 3y = 20

In this case, the terms in the first one are all the same, but multiplied by -3

And by simple elimination we can say:

-24x - 8y = 40 ≡ -6x - 2y = 10

In this case, the terms of the first equation are equal to those of the latter, but all multiplied by 4.

I dont know how to divide a line segment.
melamori03 [73]

From point A, draw a line segment at an angle to the given line, and about the same length. The exact length is not important. Set the compasses on A, and set its width to a bit less than one fifth of the length of the new line. Step the compasses along the line, marking off 5 arcs. Label the last one C. With the compasses' width set to CB, draw an arc from A just below it. With the compasses' width set to AC, draw an arc from B crossing the one drawn in step 4. This intersection is point D. Draw a line from D to B. Using the same compasses' width as used to step along AC, step the compasses from D along DB making 4 new arcs across the line. Draw lines between the corresponding points along AC and DB. Done. The lines divide the given line segment AB in to 5 congruent parts.

WILL GIVE 10 POINTS Leona was using an eyedropper to place droplets in a small container.
il63 [147K]

Answer:

A. milliliters     B. 8 fluid ounces

Step-by-step explanation:

An eyedropper is very small and can only hold a small amount.  You can eliminate 2 from the start: millimeter and meter.  These two are use for measuring distance not volume.  ex.) I walked 2 meters.  A liter is too big for an eyedropper.  ex.) 1 liter of soda.

A glass full of juice would be 8 fuild ounces because a glass is basically a cup.  A 8 gallons is too big, and a 8 tablespoons is too small.  ex.) gallon of milk and tablespoon of sugar.  8 cups is too big because a glass is about 1 cup.  8 fluid ounces = 1 cup
