Answer:
3, 15 and 30
Step-by-step explanation:
Let the first number be x
Second number is 5 times the first number = 5x
Third number is twice the second number = 2×5x = 10x
The equation becomes;
x + 5x + 10x = 48
16x = 48
x = 48 ÷ 16
x = 3
Therefore the three numbers are x = 3, 5x = 15 and 10x = 30
Answer:
4 dollars
Step-by-step explanation:

Answer:
volume formula: b*w*h
(base times width times height)
Step-by-step explanation:
here, we can see the base is 2mm, the length is 2mm, and the height is 3mm.
so, if we put them in as the base, width, and height, we get
2*2*3
then, multiply!
2*2*3
= 4*3
= 12
so, the answer is 12 cubed millimeters.
Answer: im guessing you need the amount of compound b
Step-by-step explanation:
1 think out problem
compound A =222m compound B=3 milliliters of compound A used for every 2 milliliters of compound B
write compound B as an equation which is:
a=3+2b
compound a equation is: a=222
to continue you have to make compound B equation equal b
a=3+2b
-2b -2b
a-2b=3
-a -a
-2b/-2=3/-2-a/-2
b= -3/2+a/2
i am working on the substitution method: so now you substitute variables
problems are: b=-3/2+a/2 and a=222
substute a for a: b=-3/2+222/2
b=109.5
a=222
<u>compound A=222</u>
<u>compound B=109.5</u>
<u>add both for final answer or whatever: 109.5+222= 331.5</u>
