Answer:

-580

Step-by-step explanation:

Simplify -8 + -4 to -8 - 4

Simplify -8 - 4 to -12

Since power of 2 is even, the -12 will be a positive

Simplify 12^2 to 144

Simplify 12 over 3 to 4

Simplify -4 * 144 to -576

-576 - 6 + 2

Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.
polet [3.4K]

Answer:

m\angle E=tan^{-1}(\frac{3}{4.6})

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle EFG

tan(E)=\frac{GF}{EF} ----> by TOA (opposite side divided by the adjacent side)

substitute

tan(E)=\frac{3}{4.6}

m\angle E=tan^{-1}(\frac{3}{4.6})

Which is more precise 5 kg or 5212 g
Dahasolnce [82]
5 kg is more precise because if you said 5212 g, they will be trying to see what the precise answer is so if you say 5 kg that will save all of the work. 

P.S.: its not 5212 g, its 5000 g. :)

Two thirds of a number reduced by 11 is equal to 4 more than the number. Find the number
Marina CMI [18]

2n/3 - 11 = n + 4

Add 11 to both sides:

2n/3 = n + 15

Multiply both sides by 3:

2n = 3n + 45

Isolate n:

-n = 45

n = -45

Plsss help me Show the work
jenyasd209 [6]

Answer:

x=1, y=6

(1,6)

Step-by-step explanation:

First we must isolate one of the variables (x or y) in one of the equations (First or second). Here I'll isolate y in equation 2 since it's the easiest to solve.

-2x+y=4\\y=4+2x

Now that we have successfully isolated, we will next substitute the chosen variable (y) in the opposite equation (Eq 1) with the equation we have recently formed:

2x+3y=20\\2x+3(4+2x)=20\\2x+12+6x=20\\8x+12=20\\8x=8\\x=1

Next substitute x in the opposite equation: (basically the equation we previously used to create a new equation which is Equation 2)

-2x+y=4\\-2(1)+y=4\\-2+y=4\\y=6
