Nesterboy [21]

Answer:

$w > 6$

Step-by-step explanation:

Let's solve your inequality step-by-step.

−5(w+4)+8<−42

Step 1: Simplify both sides of the inequality.

−5w−12<−42

Step 2: Add 12 to both sides.

−5w−12+12<−42+12

−5w<−30

Step 3: Divide both sides by -5.

$\frac{-5w}{-5} < \frac{-30}{-5}$

$w > 6$

<u>Answer: </u>

<u /> $w > 6$

Thanks!

You must use the LCD 1/7 + 3/14 *Convert Into into like fractions and add them

Tresset [83]

The LCD of 1/17 and 3/14 is 14.

1/7 = 2/14

3/14 = 3/14

2 + 3 = 5

The denominators are the same, so it will remain the same.

= 5/14 <===

5/14 is your answer.

I hope this helps! :)

Steven wrote this equation. 4×18=418 Explain the error in Steven's reasoning. Find the correct product. Enter your explanation a

Thepotemich [5.8K]

Given:

Steven wrote this equation:

$4\times 18=418$

To find:

The error in Steven's reasoning and then find the correct product.

Solution:

We have,

$4\times 18=418$

This statement is incorrect because we cannot write product directly as Steven wrote.

We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.

$4\times 18=4\times (10+8)$
