The solution of the equation 3x+4=25 ​

Mathematics
1 answer:
Lunna [17]3 years ago
3 0

Answer:

\huge \boxed{x=7}

Step-by-step explanation:

3x + 4 = 25

Subtract 4 from both sides.

3x + 4 - 4 =  25 - 4

3x = 21

Divide both sides by 3.

(3x)/3 = 21/3

x = 7

7 − 9x − (x + 12) less than or equal to 25?
Nonamiya [84]

Answer:

x  ≥-3

Step-by-step explanation:

7 − 9x − (x + 12) less than or equal to 25

7 − 9x − (x + 12) ≤ 25

Distribute the minus sign

7 − 9x − x - 12 ≤ 25

Combine like terms

− 10x −5 ≤ 25

Add 5 to each side

− 10x −5+5 ≤ 25+5

− 10x ≤ 30

Divide by -10. Remember that this flips the inequality

− 10x/-10 ≥30/-10

x  ≥-3

klio [65]

Answer:

58 yards^2

Step-by-step explanation:

You want to break this irregular shape into simple shapes. You can make a rectangle with the sides of 4 and 6 yards, whose are is 24 yards^2.

Then you can do the rectangle on the opposite side, whose sides are 4 and 6 yards, whose are is 24 yards^2 again.

Then the final rectangle has the sides of 5 and   2 yards, whose area is 10 yards^2.

If you add it all up, you will get 58 yards^2.

The school cafeteria ordered 42 boxes of pasta. Each box contained 24 ounces. Drag numbers from the box to write two different e
Goshia [24]

Answer:

Boxes = 1008oz

Step-by-step explanation:

Given

Boxes = 42

1\ box = 24oz

Required

Determine the number of ounces ordered

The question is incomplete, as the numbers to drag are not given. However, the alternate solution is as follows:

Boxes = 42\ boxes

This can be rewritten as:

Boxes = 42 * 1\ box

Substitute 24oz for 1 box

Boxes = 42 * 24oz

Boxes = 1008oz

<em>Hence, a total of 1008 ounces were ordered</em>
