Answer: 0

Step-by-step explanation:

2/3(18) is the same as (2*18)/3

This means it would be 36/2 which is 36.

Then you have to divide it by 2 which would give you 12. They you still have the -12 in the original problem, so you get 12-12 which is 0.

Answer:

I think the answer is 0.

Step-by-step explanation:

To evaluate an expression, you need to substitute the number(18) into the equation:

2/3(18)-12

=12-12

=0

I hope this helps!

Write the equation in function form:<br> 8x + 4y = 20
yawa3891 [41]
The answer is f(x) = 5 - 2x

Function form means just replace y with f(x).

So given 8x + 4y = 20:

Subtract 8x
4y = 20 - 8x

Divide both sides by 4
y = 5 - 2x

Use trigonometry to solve the triangle shown. Round all side lengths to one decimal place and
Eddi Din [679]

Answer/Step-by-step explanation:

Recall: SOH CAH TOA

✔️Find <A:

Reference angle (θ) = A

Opposite side = 14 cm

Hypotenuse = 20 cm

Apply SOH:

Sin θ = Opp/Hyp

Substitute

Sin A = 14/20

A = sin^{-1}(\frac{14}{20})

m<A = 44° (nearest whole number)

✔️Find <C:

Reference angle (θ) = C

Adjacent side = 14 cm

Hypotenuse = 20 cm

Apply CAH:

Cos θ = Adj/Hyp

Substitute

Cos C = 14/20

C = cos^{-1}(\frac{14}{20})

m<C = 46° (nearest whole number)

✔️Find AB:

Reference angle (θ) = C = 46°

Opposite side = AB

Hypotenuse = 20 cm

Apply SOH:

Sin θ = Opp/Hyp

Sin 46° = AB/20

20*Sin 46° = AB

AB = 14.4 cm (one decimal place)
