zepelin [54]3 years ago

Answer:

x=26

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

(2x-5)° +(4x-1)° + 30° = 180

Combine like terms

6x +24 =180

Subtract 24 from each side

6x+24-24 =180-24

6x = 156

Divide by 6

6x/6 =156/6

x =26

Adante begins to evaluate the expression 3 1/3 x 5 1/4 using the steps below
il63 [147K]

Answer:

\frac{35}{2}

Step-by-step explanation:

To solve this problem we need to write the mixed fraction as a fractional number, as follows:

3 1/3 = 3 + \frac{1}{3} = \frac{9+1}{3} = \frac{10}{3}

5 1/4 = 5 + \frac{1}{4} = \frac{20+1}{4} = \frac{21}{4}

Then, evaluating the expression:

\frac{10}{3}×\frac{21}{4} = \frac{210}{12} =  \frac{35}{2}

2<br> 1 point<br> The point, (-3, 7), is on the line y = -3x+7.<br> True<br> O False
sladkih [1.3K]

Step-by-step explanation:

  • in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
  • If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
  • Now let us plug in the value of x=-3
  • y =  - 3( - 3) + 7 \\ y =  - 9 + 7 \\ y =  - 2
  • now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
  • therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.
