Collect like terms
x + 4x - 4 = 9 - 2 x - 6
move the terms
5x - 4 = 3 - 2x
collect like terms calculate
5x + 2x = 3 + 4
7x = 7
answer is x = 1

Joelle spent 1 1/2 hours studying for her science test. Rileigh studied 3/4 for of Joelle‛s time. What fraction of an hour did R
ale4655 [162]

Answer: 1¹/₈ hours

Step-by-step explanation:

Joelle spent 1¹/₂ hours reading and Rileigh spent 3/4 of that time.

To find out how much time Rileigh spent, multiply the fractions but first convert the improper fraction to a proper fraction:

= 1¹/₂ = 3/2

= 3/2 * 3/4

= 9/8

= 1¹/₈ hours

1)Find the cost of fencing a rectangular park of length 175m and breadth 125m at the rate of 12/Rs per metre.
CaHeK987 [17]

Step-by-step explanation:

Length of rectangular park = 175 m

Breadth of rectangular park = 150 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 150)

= 2 x 325 = 650 m

Since, cost of fencing park per meter = = Rs. 12

Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800

Square park=250m

Perimeter of the square park x 4

=250x4

=1000m

So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20

=20000

What is the solution to the equation log(2x — 7) = log(5х + 2)?<br> NEEED ANSWER ASAP
slavikrds [6]

Answer:

"No Solution"

Step-by-step explanation:

We can use the log property shown below to simplify this:

Log(a)=Log(b)\\Means\\a=b

Since no "base" is given, we take base as "10" and use property to write:

2x-7=5x+2

Now, we solve for x:

2x-7=5x+2\\5x-2x=-7-2\\3x=-9\\x=-3

But we are NOT done. We have to take the value and put it into the equation to check if there is any NEGATIVE value, because we cannot take negative log.

Putting in LHS:

Log(2x - 7)

Log(2(-3) - 7)

Log(-6-7)

Log(-13)

This can't be solved. So x = -3 is not a solution. Thus, there is NO SOLUTION to the equation given.
