Answer:
x = 11
Step-by-step explanation:
7x + 3(3x + 6) = 194
<em>open the parenthesis</em>
7x + 3 * 3x + 3 * 6 = 194
7x + 9x + 18 = 194
<em>subtract 18 from both sides of the equation</em>
7x + 9x + 18 - 18 = 194 - 18
<em>combine like terms</em>
7x + 9x = 194 - 18
16x = 176
<em>divide both sides of the equation by 16</em>
16x/16 = 176/16
x = 176/16
x = 11
Answer:
See below.
Step-by-step explanation:
<u>Given</u> :
- ΔMAL ≅ ΔDLA, DL = MA, ∠MAL = ∠DLA
- ∠M = 30°
- DL = (2x + 10) cm
- MA = (3x - 2) cm
- AL = (x + 5) cm
<u>To Find</u> :
- DL
- AL
- ∠DLA
- ∠ADL
<u>Solving</u> :
- DL = MA
- 2x + 10 = 3x - 2
- x = 12
- <u>DL = 24 + 10 = 34 cm</u>
- AL = x + 5
- AL = 12 + 5
- <u>AL = 17 cm</u>
- ∠DLA = 180° - 90° - 30° = 180° - 120° = <u>60°</u>
Simplify each side of the equation by removing parentheses and combining like terms.
Use addition or subtraction to isolate the variable term on one side of the equation.
Use multiplication or division to solve for the variable.
Y=-3x-1
bc the y intercept is -1 and the slope is -3
Inequality in math or in social studies?
in math, inequality means the expression on the right hand side is not equal to the expression on the left hand side.
