Answer:

The slope is 1/2.

Step-by-step explanation:

All you have to do is see what is being multiplied by x, and that will be your slope. The number after is your "b"

X= -x over 2 (negative x as a fraction and 2 is the denominator) minus y+ (seven as the numerator over 2 as the denominator).
Solve for y by simplify both sides with inverse operations, then isolate the variable and you get, y = 3x - 1.

Felix scored 52 and 64 on his first two test in Sociology 212. What must he get on the third test to get an average of the three

Pie

Answer:

Felix's third test score must be greater than 94

Step-by-step explanation:

Felix scores on Sociology 212 tests:

1st test - 52

2nd test - 64

3rd test - x

Find the average of Felix's scores:

$\text{Average}=\dfrac{\text{The sum of all scores}}{\text{The total number of scores}}\\ \\\text{Average}=\dfrac{52+64+x}{3}$

An average of the three test must be above 70, this means

$\text{Average}>70\\ \\\dfrac{52+64+x}{3}>70$

Solve this inequality. First, multiply it by 3:

$52+64+x>210\\ \\x>210-52-64\\ \\x>94$

MZRST = (7x + 11)

SVEN [57.7K]

Answer:

see explanation

Step-by-step explanation:

Alternate exterior angles are congruent, thus

∠ RST = ∠ RQP , substitute values

7x + 11 = 4x + 32 ( subtract 4x from both sides )

3x + 11 = 32 ( subtract 11 from both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Thus

∠ RST = 7(7) + 11 = 49 + 11 = 60°

∠ RQP = 4(7) + 32 = 28 + 32 = 60°

If ABCD is a rectangle, and m∠ADB=55°, what is the value of x?

makvit [3.9K]

Answer: OPTION D.

Step-by-step explanation:

Rectangles have four right angles (angles of 90 degrees).

The point of intersection of the diagonals divides each one of them into two equal parts.

Knowing this, we can conclude that:

$m\angle c=m\angle b=55\°$

(Observe the figure)

Therefore, since the sum of the interior angles of a triangle is 180 degrees, we can find the value of "x":

$x+m\angle c+m\angle b=180\°\\x=180\°-55\°-55\°\\x=70\°$
