A, and here's how you do it:

First, just disregard the bottom half of the fraction, and focus on the top part. So on the top, you first multiply the bottom and the top of the first fraction by two, so you get:
\frac{2x}{8}  +    \frac{1}{8}
Then write all numerators above the common denominator so you get:
\frac{2x + 1}{8}
Then you can add the bottom part of the fraction back so you can have:
2x + 1
—
8
———
x²
—
4

Then multiply it by the formula:
a
—
b. a x d
— = —
c. b x c
—
d

Then you'll get:
\frac{(2x + 1) \times 4}{8 {x}^{2} }
Then reduce it by 4, so you'll get A. as your answer.

A is correct

Time 8 on both denominator and numerator

The numerator becomes 8*(x/4+1/8)=2x+1
The denominator becomes 8*(x^2/4)=2x^2

Leo had $91, which is 7 times as much money as Alison had. How much
NARA [144]

Answer:

7x=91

$13.

Step-by-step explanation:

Let x represent money that Alison has.

We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be 7x.

We are also told that Leo had $91, so we will equate 7x with 91 and solve for x as:

7x=91

To solve for x, we will divide both sides by 7:

\frac{7x}{7}=\frac{91}{7}

x=13

Therefore, Alison has $13.

One pound of swordfish costs as much as 1.5 pounds of salmon. Mrs. O pays $39 for 2 pounds of salmon and 3 pounds of swordfish.
Dimas [21]

Answer:

The ratio of the amount for swordfish to the amount of salmon is 6:4

Step-by-step explanation:

Given as :

The price for 1 pound of swordfish = The price of 1.5 pound of salmon

So, On this relation

The price for ( 1 × 2 ) pound of swordfish = The price of ( 1.5× 2 )  pound of salmon

i.e The price for 2 pound of swordfish = The price of 3 pound of salmon

Now According to question

Mrs. O pay the total money for 2 pounds of swordfish and 3 pound of salmon = $ 39

Let the money she pay for swordfish = 2 sw

And The money she pay for salmon = 3 sa

∵, The total money she pay for both  = $ 39

I.e  2 sw + 3 sa = 39

As 2 sw = 3 sa

So, 3 sa + 3 sa = 39

Or, 6 sa = 39

or, sa = \frac{39}{6} = \frac{13}{2}

∴ sw = \frac{13}{2} × \frac{3}{2}

or, sw = \frac{39}{4}

Now, the ratio of the amount for swordfish to the amount of salmon = \frac{\frac{39}{4}}{\frac{13}{2}}

I.e The ratio = \frac{6}{4}

Hence The ratio of the amount for swordfish to the amount of salmon is 6:4
