Pani-rosa [81]3 years ago

3x = 18-2y

x= 6 - 2/3y

then substitute in the second equation

Y= -2/3x + 12

y=-2/3(6-2/3y)+12

y= 72/5

then substitute y= 72/5 in the first equation x= 6 - 2/3y

then x = -18/5

Answer:

3x + 2y =18


Y= -2/3x + 12

3x + 2(-2/3x+12) = 18

3x + (-4/3x+24) = 18

3x + -1 1/3x +24 =18

1 2/3x +24 = 18

1 2/3x = -6

5/3x = -6

x = -3.75

Explain how you can use base ten blocks to find 1.54+ 2.37
solong [7]
0.00

*First column to your left - ones column (1)
*Column just after decimal place, in the middle - tenths column (1/10)
*Column to the far right - hundredths column (1/100)

The only numbers that can go in these columns are 0-9.

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

1.54 + 2.37 

= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)

= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100

= 3 + 8/10 + 11/100

= 3 + 8/10 + (10/100 + 1/100)

= 3 + 8/10 + (1/10 + 1/100)

= 3 + 8/10 + 1/10 + 1/100

= 3 + 9/10 + 1/100

= 3.91
