5 Solve for x. 8 = 2x + 4

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.

Select the correct answer from each drop-down menu.
A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 33, where x represents the smaller number. Plug in the numbers from the set {3, 5, 7, 9} to find the value of x.
The value of x that holds true for the equation is BLANK 1. So, the smaller number is BLANK 2 and the larger number is BLANK 3.

Blank 1:
3, 5, 7, 9
Blank 2:
3, 5, 7, 9
Blank 3:
24, 26, 28, 30

Answers

Answer:

look below. brainliest pls :)

Step-by-step explanation:

Blank 1: 7

Blank 2: 7

Blank 3: 26

To find the value of x, we need to substitute each number from the set {3, 5, 7, 9} into the equation x + 3x + 5 = 33 and see which value satisfies the equation.

Let's try each number one by one:

For x = 3, the equation becomes 3 + 3(3) + 5 = 3 + 9 + 5 = 17, which is not equal to 33.

For x = 5, the equation becomes 5 + 3(5) + 5 = 5 + 15 + 5 = 25, which is not equal to 33.

For x = 7, the equation becomes 7 + 3(7) + 5 = 7 + 21 + 5 = 33, which satisfies the equation.

For x = 9, the equation becomes 9 + 3(9) + 5 = 9 + 27 + 5 = 41, which is not equal to 33.

Therefore, the value of x that holds true for the equation is 7. So, the smaller number is 7 and the larger number can be calculated by adding 5 to it, resulting in 7 + 5 = 12.

Answers

Answer:

Step-by-step explanation:

first you just divide 11.25 by 9 which is 1.25. then you multiply 5 by 1.25 which is 6.25. Then you do the same with 2, multiply it by 1.25, which is 2.50. for the last one, you divide 20 by 1.25, which is 16

divide 11.25 by 9, and thats 1.25 then multiply it by 2 which is 2.5, so for 2 cartons its 2.5, for 5 cartons its 6.25, and for 20.00 is 16

Answers

Part A:

x=5
4x-1 ≤19
4(5)-1 ≤19
20-1 ≤19
19 ≤19

x=5
4x-1<19
4(5)-1<19
19<19

Explanation:
In problem one the greater then symbol has a line under it, this means that the symbol now means greater then or equal to. Since 19 is equal to 19 it is correct. In problem to the greater then symbol has no line under it meaning it only means greater then. Since 19 is not greater then 19 it is false.
So basically the difference is:
≤ = greater then or equal to
< = greater then

62 degrees is the answer 90-28 =62

We can see that the lines that meet to form angle x create 90 degrees. So, x = 90°.

Angle y = 90° - 28°

So, y = 62°.

Chloe needs to swim a total of 9 miles this week. So far this week , she swam 5 5/8 miles. Use the equation 5 5/8 + m =9 to find out how many more miles Chloe needs to swim.

Answers

Alright, so all we have to do here is solve the equation!

5 5/8 + m = 9

m = 9 - 5 5/8

Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).

m = 8 8/8 - 5 5/8

Then we can subtract fairly easily!

m = (8 - 5) + (8/8 - 5/8)

m = 3 3/8 miles
