Answer:

19

Step-by-step explanation:

Result:

28 - 3(2 + 4) + 9 = 19/1 = 19

Spelled result in words is nineteen.

How do you solve fractions step by step?

   Add: 2 + 4 = 6

   Multiple: 3 * the result of step No. 1 = 3 * 6 = 18

   Subtract: 28 - the result of step No. 2 = 28 - 18 = 10

   Add: the result of step No. 3 + 9 = 10 + 9 = 19

HOPE THIS HELPS!

What is the volume of the composite figure?<br><br> 96 ft3<br> 192 ft3<br> 76 ft3<br> 152 ft3
fenix001 [56]
The answer is 76. Split this into two rectangles, a lower and an upper.

The upper one has dimensions of 5, 4, and 2
SO its volume is 5*4*2 or 40

The lower one has dimensions of 6, 3, and 2
So its volume is 6*3*2 or 36

40+36=76

0.2(d-b)=0.3b+5-3+0.1d
Genrish500 [490]
0.2(d-b)=0.3b+5-3+0.1d 
you first distribute the 0.2 to the d and b in the parentheses, you'll then get
0.2d-0.2b=0.3b+5-3+0.1d
now you make sure that the b variables are with each other on the same side of the equal sign. so you subtract 0.3b from both sides to get 
0.2d-0.5b=5-3+0.1d
now do the same thing with the d variables so subtract 0.1d from both sides to get
0.1d-0.5b=5-3
now you can subtract 5-3 which is easy to get 
0.1d-0.5b=2
now you have to figure out what d and b equal. so i'll do b first. all you do is use the equation you have now and pretend that d is 0 so substitute the 0 in with the d variable to get
0.1(0)-0.5b=2
now you divide -0.5b from both sides to get
-0.5b/-0.5= b 2/-0.5= -4
so now you know b = -4
now you do sthe sane thing with b substitute with a 0 to get 
0.1d-0.5(0)=2
then divide 0.1d from both sides to get
0.1d/0.1=b 2/0.1=20
now you know d = 20 
( d=20, b=-4 )
