Answer:
A. 2.18 × 10^4
Step-by-step explanation:
2.18 × 10^4
10^4 = 10000
2.18 × 10000 = 21800 which is less than 22874
Answer:
5x + 11
Explanation:
3(x + 7) + 2x − 10
<u>Distribute</u>
(3)(x) + (3)(7) + 2x − 10
3x + 21 + 2x − 10
<u>Combine Like Terms</u>
3x + 21 + 2x − 10
(3x + 2x) + (21 − 10)
= 5x + 11
Direct variation has the form y=kx. Given a point we can solve for the constant k.
y=kx, when y=9 and x=-3 becomes:
9=-3k
k=-3 so the constant of variation is negative 3
Well 3+4=7 so you have two different drawings which removes one marble if you draw and then you have 6. so first, you have 3/7 green and 4/7 to draw black marble. After then, you have either a 3/7 green and 3/7 black chance or a 2/7 green and 4/7 black chance to pull a color. you're more likely to pull a black marble first, then after getting a black marble you have a 50/50 chance of pulling either back or green.
Answer:
x = -8
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
-1x = -8 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: -x = -8 - 2x
- Add 2x on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -1(-8) = -8 - 2(-8)
- Multiply: 8 = -8 + 16
- Add: 8 = 8
