(2x/3) - (4/5)=(2/6) can someone help me please?

x=1.7

Step-by-step explanation:

First I add both sides by (4/5) and subtract both sides by (2/6). This makes the equation (2x-3)-(2/6) = (4/5). Then I simplify 2/6 to 1/3 to have the left side have a common denominator of 3. Then I subtract (2x/3) by (/3) to get (2x-1)/3. This makes the equation (2x-1)/3 = 4/5. Use cross multiplication to get 5(2x-1) = 3*4. Factor the 5 in would make the left side 10x-5, and multiplying 3 and 4 would make the right side 12. 10x-5 = 12. Add 5 to both sides to get 10x=17. Divide both sides by 10 to get the final answer of 1.7

on friday there were 15 birds

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
