Solve –3d + 5 = 14.


–57

12

–27

–3

Answers

Answer 1

Answer:

d = -3

Step-by-step explanation:

–3d + 5 = 14.

Subtract 5 from each side

–3d + 5-5 = 14-5

-3d = 9

Divide each side by -3

-3d/ -3 = 9/-3

d = -3

Answer 2

Answer:

\(d = - 3\)

last answer is correct

Step-by-step explanation:

\( - 3d + 5 = 14 \\ - 3d = 14 - 5 \\ - 3d = 9 \\ \frac{ - 3d}{ - 3} = \frac{9}{ - 3} \\ d = - 3\)

Samantha earns money when she brings home good grades, but loses money when her grades are poor.

The table below shows how much money Samantha earned and lost last week.
Monday: ($2.25)
Tuesday: (-$1.75)
Wednesday-(-$0.25)
Thursday: ($3.00)
Friday: ($1.75)

If Samantha had $40.75 at the beginning of the week, how much did she have at the end of the week?
PLS SHOW YOUR WORK or i'll just take your answer off

Answers

Answer:

$45.75

Step-by-step explanation:

1. Set up the equation: 40.75 + 2.25 - 1.75 - 0.25 + 3 + 1.75 = x

You want to include the amount that she started with which is $40.75 . In this case x is the total amount of money that Samantha has by the end of the week. If Samantha loses money on a certain day you will subtract it, whereas if she gains money you will add it.

2.Simplify: 43 - 1.75 - 0.25 + 3 + 1.75 = x

I just added the 1st two numbers. You can just type this into the calculator if you are comfortable with that or you can solve this by adding and subtracting the numbers on a piece of scratch paper.

3. Simplify: 41.25 - 0.25 + 3 + 1.75 = x

4. Simplify: 41 + 3 + 1.75 = x

5. Simplify: 44 + 1.75 = x

6. Simplify: 45.75 = x

All you have to do is one by one add or subtract the numbers so if you add 2.25 to 40.75 you get 43 after that subtract 1.75. After that you get 41.25. Subtract 0.25 you get 41. Then add 3 you get 44. You add 1.75 to that and get 45.75

Help! 2/3x + 19 = 35

Answers

Answer:

x = 24

Step-by-step explanation:

Given equation,

→ (2/3)x + 19 = 35

Now the value of x will be,

→ (2/3)x + 19 = 35

→ (2/3)x = 35 - 19

→ (2/3)x = 16

→ x = 16 ÷ (2/3)

→ x = 16 × (3/2)

→ x = (16 × 3)/2

→ x = 48/2

→ [ x = 24 ]

Hence, the value of x is 24.

Answer:

We are given a perimeter and three different lengths and we need to determine the corresponding width and area.  

The first length that is provided is 2 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(2 + 6) which gives us a perimeter of 16 feet and a width of 6 feet.  We can then get the area by multiplying the length by width which gives us 12 feet squared.

The second length that is given is 4 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(4 + 4) which gives us a perimeter of 16 feet and a width of 4 feet.  We can then get the area by multiplying the length by width which gives us 16 feet squared.

The final length that is given is 5 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(5 + 3) which gives us a perimeter of 16 feet and a width of 3 feet.  We can then get the area by multiplying the length by width which gives us 15 feet squared.

Georgia has been saving her earnings from her lemonade stand. Georgia has 80 dollars to spend. If she buys a new hat for 22 dollars, how many bows can she buy with the remaining money if they cost 5 dollars each?

Answers

Answer:

Step-by-step explanation:

Because she bought a new hat for 22 dollars, subtract that from the 80 dollars.

1. 80-22=58

Next, each bow costs 5 dollars so you’ll have to see how many times 5 goes into 58 to get your answer.

2. 58/5= 11 with three dollars remaining.

That means Georgia can purchase 11 bows with the remaining money.
