How to solve 4(5x-7)=10x+2

Mathematics
1 answer:
Whitepunk [10]3 years ago
5 0
To solve:
Distribute the 4 to the 5x and –7 by MULTIPLYING.

4(5x)=20x + 4(–7)=–28

20x-28=10x+2 is your new equation.

Subtract 10x from BOTH SIDES to isolate your variable, "x".
20x-10x=10x
10x-10x=0

10x-28=2 is your new equation.

Add 28 to BOTH SIDES to isolate your variable more.
–28+28=0
2+28=30

10x=30 is your new equation.

Finally, DIVIDE both sides by 10 to finish isolating the variable.
10x/10=x
30/10=3

x=3 is your FINAL, SIMPLIFIED answer.

Anchara drops a penny from a height of 60 feet above the ground. The equation h=-16t^2 + 60 models the penbys height h i feet as
weeeeeb [17]

Answer:

t = 1.94 seconds

Step-by-step explanation:

we have to solve the following polynomial equation:

-16t² + 60 = 0

16t² = 60

t² = 60/16 = 3.75

t = √3.75 = 1.936491673 seconds

the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option
