Answer:

\sf\longmapsto \: x = 10

Step-by-step explanation:

Subtract 7 from both sides:

7−5x−7=−43−7

Simplify:

−5x=−50

Divide both sides by −5:

\sf\longmapsto \:  \frac{ - 5x}{ - 5}  =  \frac{ - 50}{5}

\sf\longmapsto \: x = 10

Mashcka [7]

Answer:

Given the statement: One pound of grapes costs $1.55.

Let x be be the cost of 3.5 pounds of grapes.

Equivalent ratios states that the  two ratios that express the same relationship between numbers.

Therefore, by equivalent ratio:

\frac{1 pound}{cost of 1 grapes} =\frac{3.5 pound}{cost of 3.5 grapes}

then, we have;

Cross multiply the above equation; we hve

x = 1.55 \times 3.5

x = 5.425

therefore, the cost of 3.5 pounds of grapes is, $5.425
