Answer:

Step-by-step explanation:

2(x + 15)⁰ + (3x + 20)⁰=180⁰

2x + 30⁰ + 3x + 20⁰=180⁰

2x + 3x + 30⁰ + 20⁰=180⁰

5x + 50⁰ - 50⁰=180⁰-50⁰

5x=130⁰

5x/5=130⁰/5

x=26⁰

Answer:

x should equal 26.

Step-by-step explanation:

since they are cointerior angles:

2 (x + 15) + (3x + 20) = 180

2 (x) + 2 (15) + (3x + 20) = 180

2x + 30 + (3x + 20) = 180

2x + 30 + 3x + 20 = 180

5x + 50 = 180

5x + 50 - 50 = 180 - 50

5x = 130

5 ÷ 5x = 130 ÷ 5

x = 26

$\bf \cfrac{small}{large}\qquad \cfrac{s}{s}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\implies \cfrac{2}{7}=\cfrac{\sqrt[3]{32}}{\sqrt[3]{v}}\implies \cfrac{2}{7}=\sqrt[3]{\cfrac{32}{v}}\implies \left( \cfrac{2}{7} \right)^3=\cfrac{32}{v}
\\\\\\
\cfrac{2^3}{7^3}=\cfrac{32}{v}\implies v=\cfrac{7^3\cdot 32}{2^3}$

What is -6w < 85. help

dolphi86 [110]

Answer:

w=[-14.1667, ∞)

Step-by-step explanation:

the variable w can be any real number less than the value of 85, thus -6 multiplied by any number greater than the value of 14.1667 shall be less than 85. the value for the minimum limit number is obtained dividing 85 by -6 due to the varibale -6w and the value 85 as the maximum limit.
