The value of n in the given equation is -2.6
Step-by-step explanation:
Given,
10 = 
To find the value of n
10 =
or, 10(3n+8) = 2 [ by cross multiplication]
or, 30n + 80 = 2
or, 30n = 2-80 [ taking the constant values in one side]
or, 30n = -78
or, n = 
or, n = -2.6
Answer:
8.30256
Step-by-step explanation:
Step 1: Write out expression
Step 2: Use BPEMDAS to evaluate
= 8.30256
And we have our answer!
0.5, you would divide 0.375 to cancel out the height and then divide 0.75 (the new volume after you divided 0.375 by the height) by 1.5 to cancel out the x
Answer:
The answer would be (1.23, 4.39)
Step-by-step explanation:
Because they are both equal to y, we can set the equations equal to each other and then solve.
4.9x - 1.64 = -0.25x + 4.7
5.15x - 1.64 = 4.7
5.15x = 6.34
x = 1.23
Now that we have the value for x, we can plug into either equation and find y.
y = -0.25x + 4.7
y = -0.25(1.23) + 4.7
y = -.31 + 4.7
y = 4.39

Step-by-step explanation:
Let's solve for x.
2y+5x=4
Step 1: Add -2y to both sides.
5x+2y+−2y=4+−2y
5x=−2y+4
Step 2: Divide both sides by 5.
5x
