\Huge{\underline{\underline{\sf{\green{Answer:}}}}}

a) 2 (5x-3) = 24

= 10x -6 = 24

= 10x = 24+6

= 10x = 30

= x= 30/10

\boxed{\sf{x = 3}}

b) 5 (2x+1) = 50

= 10x+5=50

= 10x = 50-5

= 10x = 45

= x = 45/10

\boxed{\sf{x = 4.5}}

c) (3x+4)/2=9.5

= (3x+4)/2=95/10

( On cross multiplication )

= 10(3x+4) = 2×95

= 30x+40=190

= 30x=190-40

= 30x=150

= x=150/30

(on simplification)

\boxed{\sf{x = 5}}

d) (7+2x)/3=5

(On cross multiplication)

= 1(7+2x)=5(3)

= 7+2x=15

= 2x=15-7

= 2x=8

= x=8/2

(on dividing)

\boxed{\sf{x = 4}}

4(5x-2)=2(9x+3)<br> help please!<br> 12 points and<br> brainliest
photoshop1234 [79]

Answer:

x = 7

Step-by-step explanation:

Given

4(5x - 2) = 2(9x + 3) ← distribute parenthesis on both sides

20x - 8 = 18x + 6 ( subtract 18x from both sides )

2x - 8 = 6 ( add 8 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Please help I really need help please

Answer:

A

Step-by-step explanation:

The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is a^2 + b^2 = c^2 where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

a = 6, b = 8, c= 10\\6^2 + 8^2 = 10^2\\36 + 64 = 100\\100 = 100

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
