I need help solving -3x+6<-18

2 answers:

8 0

Hello!

To solve this you solve it like an algebraic equation

-3x+6 < -18

subtract 6 from both sides

-3x<-24

Divide both sides by negative 3
If you divide by a negative number you flip the sign.

x > 8

So the answer is 8 < x < infinity

This is because the answers can be any number above 8

Hope this helps!

Answer: 10

the distance between 2 points is $\sqrt{(-3-5)^{2} +(4-(-2))^{2} }=\sqrt{(-8)^{2}+6^{2} }=\sqrt{100}=10$

Answer:

≈ 47.2 m

Step-by-step explanation:

let the height from the sea to the base of lighthouse be h₁

let the height from the sea to the top of the lighthouse be h₂

using the tangent ratio in the right triangle

tan55.1° = $\frac{opposite}{adjacent}$ = $\frac{h_{1} }{610}$ ( multiply both sides by 610 )

h₁ = 610 tan55.1°

tan56.5° = $\frac{h_{2} }{610}$ ( multiply both sides by 610 )

h₂ = 610 tan56.5°

then

height of lighthouse = h₂ - h₁

= 610 tan56.5° - 610 tan55.1°

= 610(tan56.5° - tan55.1° )

≈ 47.2 m ( to the nearest tenth )

some say that to brew an excellent cup of coffee, you must have a brewing temperature off 200 degrees, plus or minus five degree

ASHA 777 [7]

Your equation for the maximum brewing temperature should be x = 200 + 5 because according to your word problem, the temp. can be five degrees above 200 degrees.

x = 200 + 5
x = 205

Your equation for the minimum brewing temperature should be x = 200 - 5 because according to your word problem, the temp. can be five degrees below 200 degrees.

x = 200 - 5
x = 195
