We have to add the amounts:
4(2x+3y) + 3(5x+4)
First, though, we have to distribute:
4*2x + 4*3y + 3*5x + 3*4
8x + 12y + 15x + 12
Now we just need to simplify:
23x + 12y + 12
The students planted 23x + 12y + 12 trees total.
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
Answer:
557.89
Step-by-step explanation:
Download photomath on Appstore it'll help you explain. but basically you multiply each digit at the bottom to the whole number on the top
23.50
<u>x </u><u>23.74</u>
940 ====== 23.50 multiply to 4
16450 ====== 23.50 multiply to 7
70500 ====== 23.50 multiply to 3
<u>+ 470000 </u> ====== 23.50 multiply to 2
557.890 ====== Add all the numbers together, move the decimal sign down to align with the result
