Answer:

subtraction

Step-by-step explanation: the difference between 2 and -3 is 5 and so on... since the numbers have a minus sign beside them, it should be easier to know that the numbers are subtracting. :)

Answer:

Sin (E) = √74/(2√23)

Step-by-step explanation:

Reference Angle = E

Hypotenuse = 2√23

Adjacent = 3√2

Opposite = DC = √(2√23)² - (3√2)²) = √(4*23 - 9*2) = √(92 - 18) = √74 (pythagorean theorem)

Recall SOHCAHTOA.

Thus,

Sin (E) = opp/hyp

Sin (E) = √74/(2√23)

2(4x-1)+3=7<br> i'm little confused on this
Ratling [72]

Answer:

x = \frac{3}{4}

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = \frac{6}{8}  <----- to reduce, divide the numerator and denominator by 2

Hence,

x =  \frac{3}{4}
