Answer:
4.8x4=19.2, and then 19.2/4=4.8 feet
Each side would be 4.8 feet
Lets answer this:-
1st lets divide to see how many times 28 goes in 8. And then we will multiply....
28 ÷ 8 = 3.5
Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:-
3.5 × 6 = 21
So, 21 symphonies are equal to 28 concerts.
Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer.
42 ÷ 6 = 7
7 × 8 = 56.
So, 56 concerts are equal to 42 symphonies.
Hope I helped ya!!
Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
x + 3y = - 1 → (1)
- 2x - 3y = 5 → (2)
Adding the 2 equations term by term will eliminate the y- term
- x + 0 = 4
- x = 4 ( multiply both sides by - 1 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
- 4 + 3y = - 1 ( add 4 to both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (- 4, 1 )
(-7x + 2)^1/3 = (4 + 3x)^1/3
take the cube of both side to eliminate the 1/3 power
so you get
-7x+2=4+3x
combine like terms
-10x=2
solve for x
x=-1/5
