Solve the equation 9z-5-4z= -5
Katyanochek1 [597]

Answer:

z = 0

Step-by-step explanation:

Step 1: Write equation

9z - 5 - 4z = -5

Step 2: Solve for <em>z</em>

  1. Combine like terms: 5z - 5 = -5
  2. Add 5 to both sides: 5z = 0
  3. Divide both sides by 5: z = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9(0) - 5 - 4(0) = -5

0 - 5 - 0 = -5

-5 = -5

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle = 35°

Opposite Leg = <em>x</em>

Hypotenuse = 20

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [sine]:                    sin35° = x/20
  2. Isolate <em>x</em>:                                 20sin35° = x
  3. Evaluate:                                 11.4715 = x
  4. Rewrite:                                  x = 11.4715
  5. Round:                                    x ≈ 11.5

A running trail 6 1/2 miles long. Leigh plans on running this trail over the course of 4 days. How much of the trail will she ha
Aliun [14]

Answer:

1 \frac{5}{8}

Step-by-step explanation:

To figure out this problem we need to divide 6 1/2 by 4.

Convert any mixed numbers to fractions. Then your initial equation becomes:

\frac{13}{2} \div \frac{4}{1}

Applying the fractions formula for division:

= \frac{13 \times 1}{2 \times 4}

= \frac{13}{8}

Simplifying 13/8, the answer is:

= 1 \frac{5}{8}

5 less than 3 times a number is 7. How would I write this as an equation
sladkih [1.3K]
You want to break this down.

“5 less than” means you’ll subtract 5 from something.

That something is “3 times a number.” “3 times a number” means 3•x or 3x, since we’ll use x for that unknown number.

So, “5 less than 3 times a number” means “subtract 5 from 3x”: 3x-5

“Is” means “equals”. So 3x-5= something.

7, well, that’s 7.

So “5 less than 3 times a number is 7” means ”subtract 5 from 3x and set that equal to 7.”

3x-5=7
