elena-14-01-66 [18.8K]

Answer: 60^{\circ}

Step-by-step explanation:

Given

Andy wants to turn 180^{\circ} on his skateboard

Currently, he can make a turn of 120^{\circ}

The difference between the required and current turn degree meets his goal i.e.

\Rightarrow 180^{\circ}-120^{\circ}\\\Rightarrow 60^{\circ}

Thus, he needs to turn by 60^{\circ} to meet his goal

NEED HELP ASAP!!!!!!!!!!!<br><br> 2. Solve for x<br> 3. Solve for x
Anton [14]

Answer:

2. x = 47

3. x = 2

Step-by-step explanation:

These problems involve proportions, or equivalent ratios.  You can solve for 'x' in each by using cross-multiplication and division.

2.  28(7) = 4(x + 2)

Distribute = 196 = 4x + 8

Subtract 8 from both sides: 196 - 8 = 4x + 8 - 8 or 188 = 4x

Solve for x:  x = 47

3.  2(2x + 7) = 11(3x - 4)

Distribute: 4x + 14 = 33x - 44

Add 44 to both sides: 4x + 14 + 44 = 33x - 44 + 44 or 4x + 58 = 33x

Subtract 4x from both sides: 4x + 58 - 4x = 33x - 4x or 58 = 29x

Solve for x: x = 2

Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss
attashe74 [19]
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5

1/5x+3y/2=2  => (1/5)x + (3/2)y = 2

Eliminate the fractional coefficients:  Mult. the first equation by 4 and mult. the second equation by 10:


2x + 15y = 20     

</span><span>Multiply the 1st equation by -1:

-</span>2x - 3y = -20
2x + 15y = 20 
-------------------
       12y = 0, so y = 0.  Then the first equation becomes  2x + 3(0) = 20, or
                                     x=10.

Solution is (10,0).
