Answers

Answer:

It would be 10

Answer:

A) 12

Step-by-step explanation:

Yes you have to do a² + b² = c²

So the bottom triangle is 3 and 4 so plug in.

4² + 3² = c² (simplify)

16 + 9 = c²

25 = c² (square root both sides)

5 = c

That gives us the vertical side of the second triangle.

So plug in again

5² + b² = 13² (simplify)

25 + b² = 169 (subtract 25 on both sides)

b² = 144 (square root both sides)

b = 12

x = 12

Hope this helps ya!!

Lashonda has scored 69 , 65, and 77 on her previous three tests. What score does she need on her next test so that her average (mean) is 69?

Answers

Answer: 65

Step-by-step explanation:

We know that her three tests are 69,65,77 so far

in order to get her average at 69 we need to do the following:

69+65+77+x=(69x4)

211+x=276

x=276-211=65

if she will get a 65 her average will be 69

X=?
Plz help

Answers

Answer:

x = 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-4x + 2 = -22

Step 2: Solve for x

Subtract 2 on both sides: -4x = -24Divide -4 on both sides: x = 6

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -4(6) + 2 = -22Multiply: -24 + 2 = -22Add: -22 = -22

Here we see that -22 does indeed equal -22.

∴ x = 6 is a solution of the equation.
