Answer:

x = 0

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

7x - 4 (+4) = -4 (+4)

7x = -4 + 4

7x = 0

Next, divide 7 from both sides of the equation:

(7x)/7 = (0)/7

x = 0/7

x = 0

0 is your answer.

A baseball diamond is 90 feet square (NOT 90 square feet!). Coach Jack Handley runs from first base to second base at 25 feet pe
OverLord2011 [107]

Answer:

dx/dt = 5√5/2

Step-by-step explanation:

Given:

dx/dt = 25 feet per second

According to Pythagoras theorem:

x² + 90² = y²

We know that x = 30 ft

So,

x² + 90² = y²

30² + 90² = y²

y = 30√10

So,

x² + 90² = y²

By taking differentiate:

2x dx/dt = 2y dy/dt

[x/y][dx/dt] = dy/dt

dx/dt = 5√5/2

Solve. 8+2=16106. 5+4=2091. 9+6=54153. 7+5=35122. 20+3=602317. 30+1=303129. 18+4=722214. 10+5=??​
Sergio [31]

answer:

505155

step-by-step explanation:

  • multiply, add, and subtract the first two numbers of the equation in that order to get the final number

8 + 2 = 16106: 8 x 2 = 16, 8 + 2 = 10, 8 - 2 = 6 to get the number 16106

5 + 4 = 2091: 5 x 4 = 20, 5 + 4 = 9, and 5 - 4 = 1 to get the number 2091

9 + 6 = 54153: 9 x 6 = 54, 9 + 6 = 15, and 9 - 6 = 3 to get the number 54153

7 + 5 = 35122: 7 x 5 = 35, 7 + 5 = 12, and 7 - 5 = 2 to get the number 35122

20 + 3 = 602317: 20 x 3 = 60, 20 + 3 = 23, and 20 - 3 = 17 to get the number 602317

30 + 1 = 303129: 30 x 1 = 30, 30 + 1 = 31, and 30 - 1 = 29 to get the number 303129

18 + 4 = 722214: 18 x 4 = 72, 18 + 4 = 22, and 18 - 4 = 14 to get the number 722214

10 + 5 = 505155: 10 x 5 = 50, 10 + 5 = 15, and 10 - 5 = 5 to get the number 505155
