Answer:
12.5
Step-by-step explanation:
Step 1:
0.4 ( 3b + 10 ) = 19 Equation
Step 2:
1.2b + 4 = 19 Multiply
Step 3:
1.2b = 15 Subtract 4 on both sides
Step 4:
15 ÷ 1.2 Divide
Answer:
b = 12.5

He volume of the right rectangular prism is 120
I thought this was a vector problem but no, this is quite easy!
You are correct; this draws the letter W.
The so-called "vector" means for you to translate the same distance. That vector goes left 3 and up 4 -- translate your point at Step 2 left 3 units and up 4 units. There you go!
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
C I believe the -2 part that was the one just looked it up on google XD hope it helped
