The value of x for which the expressions 3x – 4 and 2x + 1 become
kozerog [31]

Answer:

x=5

Step-by-step explanation:

To determine for which value of x a pair of expressions will be equal, we will need to set them equal to each other and then solve for x.

3x-4=2x+1

First, we can add 4 to each side

3x=2x+5

Now we can subtract 2x from each side

x=5

Now, just to check our answer, we can plug in our answer back into the original equation to see whether we get the same result for each side

3(5)-4=2(5)+1\\\\15-4=10+1\\\\11=11

Literally worth 100 POINTS answer the question!!!! WILL AWARD BRAINLIEST but only if work is shown and answer is actually CORREC
True [87]
The answer is 9/16 (decimal form:0.5625)

Since you have a multiply 2 and a divide 2, they cancel each other out (so you can remove both)
(1/2)^2 + 1/4 + (1/4)^2

Simplify both fractions with exponents
1/4 + 1/4 + 1/16

Add both 1/4
2/4= 1/2

1/2 + 1/16 = 9/16

Please give brainliest!!
