Answer:
2 g/cm³
Step-by-step explanation:
The volume is not given, so find that first:
2 cm x 3 cm x 2 cm = 12 cubic cm = <em>V</em>
Mass is given: <em>m </em>= 24 g
Using the density formula, solve:
<em>d </em>= <em>m</em>/<em>V</em>
<em>d </em>= 24 g/12 cubic cm
<em>d </em>= 2 g/cubic cm
Answer:
49 and 118
Step-by-step explanation:
Let the two numbers be x and y
x+y = 167
y = 3x-29
Substitute into the first equation
x+ 3x-29 = 167
Combine like terms
4x - 29 = 167
add 29 to each side
4x = 167+29
4x = 196
Divide by 4
4x/4 = 196/4
x = 49
x+y = 167
49+y = 167
y = 167-49
y =118

Answer:
C. $11.55
Step-by-step explanation:
First, multiply 4 by $0.85 to get an answer of $3.40. Next, multiply 6 by $1.25 to get an answer of $7.50. Add up the cost of the pencils and pens by adding $3.40 and $7.50 to get $10.90. Next, we have to add the tax. Multiply $10.90 by 0.06 to get $.65. Add the $.65 to the $10.90 for a grand total of $11.55. Hope this helps!
Answer:
2/5 m - 1/5
Step-by-step explanation:
2 ( 1/5 m - 2/5) + 3/5
Distribute
2/5 m - 4/5 + 3/5
Combine like terms
2/5 m - 1/5
