Solve the linear equation - 7(x + 2) = -3(x - 5) for x

melisa1 [442]

x= −29/4

Answer:

Step-by-step explanation:

−7(x+2)=−3(x−5)

Step 1: Simplify both sides of the equation.

−7(x+2)=−3(x−5)

(−7)(x)+(−7)(2)=(−3)(x)+(−3)(−5)(Distribute)

−7x+−14=−3x+15

−7x−14=−3x+15

Step 2: Add 3x to both sides.

−7x−14+3x=−3x+15+3x

−4x−14=15

Step 3: Add 14 to both sides.

−4x−14+14=15+14

−4x=29

Step 4: Divide both sides by -4.

−4x −4

x=29/−4

x= −29/4

Sindrei [870]

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70

Step-by-step explanation:

Step 1 :

Let x be the regular price of the pastry in the bakery

Percentage of discount = 25%

Amount of discount = 0.25 x

The expression to find the sale price of pastry = x - 0.25 x = 0.75 x

Step 2 :

Sale price of the pastry bought by Kimberly = $2.03 = 0.75 x

<u>To find the regular price</u>

0.75x = 2.03

x = $\frac{2.03}{0.75}$ = 2.70

Regular price of the pastry bought by Kimberly = $2.70

Step 3 :

Answer :

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70

Firdavs [7]

Answer: 180 cookies

Step-by-step explanation: If 1.75 cups of flour is required to make a batch and the bakery used 5.25, the bakery made 3 batches, since 1.75(3) is 5.25. One dozen is 12 cookies, and there are 5 dozen cookies in each batch. If there are 3 batches, then there are 15 dozens of cookies. 15(12) is 180.
