(8x+1)+(4x+11)=180°solve for x

1 answer:

3 0

You would combine like terms, so it would become 12x +12=180 Then you would subtract 12 from both sides so that the x is on one side and the just plain numbers are on the other side. So your equation now is 12x=168 You then at this point would divide both sides by 12 to get the x alone. Your final answer then would be x=14

Hello!

Let O be the center of the sphere, A the tangency point and B the location of the satellite.

m<ABO = 1/2m(b) = 1/2 * 138 = 69

m<OAB = 90

m<AOB = 180 - 90 - 69 = 21

21 * 2 = 42

The answer is 42°

Hope this helps!

Slope = y2-y1 / x2 - x1

= -8-2 / -10-5
= -10 / -15
= 2/3

√

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr

devlian [24]

Answer:

Step-by-step explanation:

Total number of tools for both = 564.

Dr Brown used 386 tools for 6 experiments.

average number of tools per experiment used by Dr Brown = $\frac{386}{6}$

= 64 $\frac{1}{3}$

Dr Rachal used 236 tools for 8 experiments.

average number of tools per experiment used by Dr Rachal = $\frac{236}{8}$

= 29 $\frac{1}{2}$

i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64 $\frac{1}{3}$ )

= 2.7668

Dr Brown can do two more experiments.

The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29 $\frac{1}{2}$ )

= 11.1186

Dr Rachal can do 11 more experiments.

ii. Number of tools left after Dr Brown's experiments = 564 - 386

= 178

Number of tools left after Dr Rachal's experiments = 564 - 236

= 328
