Solve for w in the equation: 0.4w + 2.45 = 8.75

Mathematics
1 answer:
ASHA 777 [7]3 years ago
3 0

Answer:

w= 15.75 or 15 3/4

Step-by-step explanation:

So I would multiply 100 on both sides to get rid of the decimals so I’d end up with 40w+245=875

Now solve it by subtracting 245 on both sides.

40w=630

now divided 40 on both sides

15 3/4

Final answer 15 3/4 or 15.75

The temperature was less than -15°C. Write an equality and three possible solution.​
Dmitry_Shevchenko [17]

Answer:

x < -15*C (I can’t make the degrees sign on my iPad, so I put * instead).

3 Possible Answers:

-38*C

-26*C

-57*C

Step-by-step explanation:

Inequality:

x = temperature

< = less than

-15*C = the amount the temperature was less than

3 Possible Outcomes:

Because the temperature is less than -15*C, it can literally be any number that is farther down the number line. Because it’s a negative number, anything like -14, -13, -12, and so on would actually have a greater value (think of it as in being less in debtm or in this case, less below zero). Instead, you’ll do any number like -16, -17, -18, and so on. You can even do a decimal number, like -19.5. I hope this makes sense to you!

Simplify 5/8×8 and explanation thanks.
Paha777 [63]
Explanation: Since 5/8 x 8 can be answered (because there is no variable), turn the whole number "8" into a fraction which would be: 8/1. Now, 5/8 x 8/1 equals 40/8 because 5 x 8 = 40 and 8 x 1 = 8. Now, simplify 40/8, which would be 20/4, simplifying it, even more, would be: 10/2, and one more time: 5/1 which is equivalent to 5. Hope this helps!

4x + 27 = -33 - x please help
Rudik [331]

Answer: x=-12

Step 1: Simplify both sides of the equation.

4x+27=−33−x

4x+27=−33+−x

4x+27=−x−33

Step 2: Add x to both sides.

x+27+x=−x−33+x

5x+27=−33

Step 3: Subtract 27 from both sides.

5x+27−27=−33−27

5x=−60

Step 4: Divide both sides by 5.

x=−12
