Answer:
ur answer is
6
Step-by-step explanation:
5x + 6y = 7 SUBSTITUTION METHOD
2x + 2y = 4
5x + 6y = 7 Solve for either x or y in 1 of the 2 equations.
- 6y - 6y
-----------------------
5x = -6y + 7
----- ------ ----
5 5 5
x = -6/5y + 7/5
2(-6/5y + 7/5) + 2y = 4 Substitute the expression you got for x or y into
-12/5y + 14/5 + 2y = 4 the other equation.
-2/5y + 14/5 = 4
- 14/5 - 14/5
------------------------------
-2/5y = 6/5
-------- --------
- 2/5y - 2/5y
y = -3
5x + 6(-3) = 7 Plug in the value you got for y in step 2 into the
5x - 18 = 7 equation that you didn't use.
+ 18 + 18
------------------
5x = 25
--- -----
5 5
x = 5
(x,y) ⇒ coordinate
(5,-3) ⇒ final answer
Answer:
Step-by-step explanation:
We are given that
Base side of square pyramid, a=3 m
Height of square pyramid, h=9m
We have to find the rate of change of the volume of the pyramid at that instant.
Volume of square pyramid, V=
Differentiate w.r.t t
Substitute the values
Hence, the rate of change of the volume of the pyramid at that instant=
5f+11g+15h
Explanation:
2f+5g+7h+3f+6g+8h
You just combine the like terms
5f+11g+15h
Hello! :)
To solve your equation, we will first simplify both sides of the equation
-7 = -1 + x/3
-7 = -1 + 1/3x
-7 = 1/3x - 1
Next, we will flip the equation
1/3x - 1 = -7
Third, we will add 1 to both sides
1/3x - 1 + 1 = -7 + 1
1/3x = -6
Last, we will Multiply both sides by 3
3 * (1/3x) = (3) * (-6)
x = -18 (ANSWER)
That means -18 is you answer
Hope this helped you!
