Step-by-step explanation:
<u>Step 1: Define</u>
-7 - 3x = 1x + 4(2 + x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 4: -7 - 3x = x + 8 + 4x
- Combine like terms: -7 - 3x = 5x + 8
- [Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8
- [Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x
- [Division Property of Equality] Divide 8 on both sides: -15/8 = x
- Rewrite/Rearrange: x = -15/8
Answer:
C
BEFORE THE LAST
Step-by-step explanation:
Answer:
2x-9y=-51
2x-3y=-9
subtract question ii from i we get
-6y = -42
y =7
put value of y in 1
2x - 63 = -51
2x= 8
x=4
Answer:
y = -4/5x + 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form: 4x + 5y = 20
<u>Step 2: Rewrite</u>
- Subtract 4x on both sides: 5y = 20 - 4x
- Divide 5 on both sides: y = 4 - 4/5x
- Rearrange: y = -4/5x + 4
Answer:
Infinity
Step-by-step explanation:
It is possible for the coin to endlessly fall on tails, so there are infinity different outcomes.
Tell me if I'm wrong :)
