Could someone please help me? x = 100 120 140

Answer:

x = 140

Step-by-step explanation:

The secants exterior angle theorem states that when two secants (lines that intersect a circle at two points) intersect each other outside of the circle, then the absolute value of the difference divided by (2) equals the angle formed by the intersection of the two secants. One can apply this theorem here by stating the following, call the measure of the unknown arc (y);

\frac{30-y}{2}=10

Solve for (y) with inverse operations:

\frac{30-y}{2}=10\\\\30-y=20\\\\y = 10

When there is a diameter in a circle, the degree measure of the arc surrounding the diameter is (180). One can apply this here by stating the following:

30 + x + 10 = 180

Simplify,

40 + x = 180

Inverse operations,

40+x=180\\\\x = 140

Ben adopted 2 cats and 3 dogs. He spent a total of $455. If each dog cost him $82, how much did one cat cost him?
monitta

Answer:$104.5

Step-by-step explanation:

cats=c

Dogs=d

2c+3d=455

d=82

Substitute d=82 in 2c+3d=455

2c+3(82)=455

2c+246=455

Collect like terms

2c=455-246

2c=209

Divide both sides by 2

2c/2=209/2

c=104.5

1 cat cost $104.5

Brandon is thinking of a number that is divisible by 6 and 8 . What is the smallest number that Brandon could think of
a_sh-v [17]

since

6 = 2 * 3 <--- two factors


8 = 2 * 2 * 2 <--- three factors


and since the "2" is there on each, then we can just use that instance of it once.


so instead of using 2 * 3 * 2 * 2 * 2, we'll use 2 * 3 * 2 * 2, and that is our LCD.


2 * 3 * 2 * 2 = 24.
