First distribute 8 and 3 through parenthesis. this makes the equation
2x+8x+24=3x-39

collect like terms, such as “2x+8x” this becomes 10x. plug in 10x.

10x+24=3x-39. now move variable and constant. 10x-3x=-39-24
collect like terms again. 10x-3x becomes 7x.

7x=-39-24.
-39-24=-63

7x=-63 divide both sides by 7.

x=-9

Answer:

x = -9

Step-by-step explanation:

2x + 8( x + 3 ) = 3( x - 13 )

Dstribute;

2x + 8 ( x + 3 ) = 3 ( x - 13 )

2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))

2x + 8x + 24 = 3x - 39

Combine like terms;

2x + 8x + 24 = 3x - 39

10x + 24 = 3x - 39

Inverse operations;

10x + 24 = 3x - 39

-3x            -3x

7x + 24 = -39

     -24     -24

7x = - 63

/7       /7

x = -9

If sin 20 degree=a and cos20 degree=b then which of the following represents the correct value of sin 70 degree in terms of a an
Scorpion4ik [409]

ANSWER

3) b

EXPLANATION

Given that:

\sin(20 \degree)  = a

and

\cos(20 \degree)  = b

Recall that the sine and cosine functions are equal for complementary angles.

This implies that,

\sin(70 \degree)  =  \cos(20 \degree)

\sin(70 \degree) = b

Jake set up a study schedule. The plan called for him to study 1/4 hour, 5/8 hour and 1 hour on Monday Tuesday and Wednesday in
Ludmilka [50]
Each day his study time is increasing. Find a common denominator, in this case 8

1/4 = 2/8
5/8 = 5/8
1 = 8/8

So he went from

2/8 to 5/8 to 8/8 which is an increase of 3/8 each day. If this pattern continues Thursday would be 11/8 and Friday 14/8.

14/8 = 1 6/8 = 1 3/4 hours
