Answer:
The answer to your question is: volume = 4 cm³
Step-by-step explanation:
Data
density = 2 g/cm³
Volume = ?
mass = 8 g
Formula
density = mass / volume
volume = mass / density
Substitution
volume = 8 / 2
volume = 4 cm³
Answer:
x = 2
Step-by-step explanation:
The solution set can be found by dividing the inequality by the coefficient of x.
6x > 7
x > 7/6
The smallest integer greater than 7/6 is 12/6 = 2.
The smallest integer solution is x = 2.
The given are:
cost for each blog = $20
cost for each feature article = $60
blog = 10+2(number of articles sold)
total earnings = $700
where,
a = article
b = blog
to solve,
60(a)+20(10+2a)=700
60a+200+40a=700
200+100a=700
100a=700-200
100a=500
a=500/100
a=5
The total feature articles produced last week was 5.
to check,
a+b=700
60(5)+20[10+2(5)]=700
300+20(10+10)=700
300+200+200=700
700=700
Indeed, the number of articles produced last week was 5.
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
