Answer: The value of x is 29°,  the measure of angle 1 is 123°, and the measure of angle 2 is 57°.

Step-by-step explanation:

A linear pair is the same as a straight line meaning that the sum of the two angles has to equal 180 degrees.

In this case, add both angles and set them to equal to 180 in order to solve for x.

(4x + 7) + (2x-1) = 180   Combine like terms on the left side.

(4x + 2x) + ( 7 - 1) = 180

   6x + 6 = 180   Now subtract 6 from both sides

         -6      -6

    6x = 174    Divide both sides by 6

x = 29  

Since x is  29  degrees we will input it into the expression for the angles and solve for the real value.

m ∠1 = 4(29) + 7

m ∠1  = 116 + 7

m ∠1   = 123  

If the measure of angle 1 is 123 degrees then you can subtract that from  180 to find the measure of angle two or you can use the expression.

m ∠2 = 2(29) -1

m ∠2 = 58 - 1

m ∠2  = 57

Which of the following equations is not a linear equation?
salantis [7]

Answer:

D.

Step-by-step explanation:

All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)

The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x2 + 5x
nikdorinn [45]

Answer:

  width: 15 inches; length: 20 inches

Step-by-step explanation:

The equation tells you the product of width (x) and length (x+5) is 300, so you're looking for factors of 300 that differ by 5.

  300 = 1·300 = 2·150 = 3·100 = 4·75 = 5·60 = 6·50 = 10·30 = 12·25 = 15·20

The factors in the last pair on this list differ by 5, so we have ...

  • width = 15 inches
  • length = 20 inches
