Write a real world problem that you can model with the two step equation 5x+7=10. then solve the problem

x=0.6

Step-by-step explanation:

One problem may be: Jane spent $ 10 on candy for her daughter. This was 7 times more than 5 times what she spent the last time she bought candy. How much did you spend last time?

5*x+7=10

First, you have to know that there are two pairs of inverse operations: addition and subtraction, multiplication and division.

Formally, to solve an equation we must isolate the unknown x.

For that, you change the numbers from one side of an equation to the other. For that, first the number 7, which is adding on the left side, will go to the right side of the equation with the opposite operation, the subtraction:

5*x=10-7

5*x=3

Then, to isolate "x", as 5 is multiplying, go to the other side of the equation by dividing.

x=0.6

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

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
