Answer:

120 Degrees

Step-by-step explanation:

Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations

subtract 31x from both sides to get -4 = -2x + 4

Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

X/2.4+39=239<br> show work

grin007 [14]

Answer: x = 480

Steps: x/2.4 + 39 = 239

Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39

Simplify: x/2.4 = 200

Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4

Simplify: x = 480

Geometry: The base of a triangle is 12 in. Its height is (x + 6) in. Its area is no more

larisa [96]

Answer:

The area of a triangle= bh/2. Substitute

12(x+6)/2 ≤ 72

12(1/2x+3) ≤ 72

6x+36 ≤ 72

6x ≤ 72-36

6x ≤ 36 Divide both sides by 6

x ≤ 6

x|x ≤6 (read: x, where x is equal or smaller than 6)

Please help me answer this!!!!

<h3><u>Answer</u><u>:</u></h3>

$7 \frac{1}{2}$

<h3><u>Explan</u><u>ation</u><u>:</u></h3>

First, convert any mixed numbers to fractions. An easy way to convert:

$4 \frac{1}{2} = 4 \times 2 + 1$

$\frac{9}{2} \div \frac{3}{5}$

Then, apply the fractions formula for division.

$\frac{9 \times5 }{2 \times 3} = \frac{45}{6}$

Then, simplify.

$\frac{45}{6} = 7 \frac{1}{2}$

What are two differences between factors and multiples

Feliz [49]

Answer:

Factor is a number that can be multiplied with a particular number to obtain another number. Conversely, multiples are the product, which is reached after multiplying the number by an integer. The number of factors of a particular number is limited, but the number of multiples of a given number is endless.
