I need help on finding x?

Mathematics
1 answer:
Readme [11.4K]3 years ago
8 0

Answer:

The equations (6x+42) degrees and (18x-12) degrees are congruent angles so to set up the equation, put both expressions on different sides of the equals sign. Use properties of equality to get x=4.5

Step-by-step explanation:

Your equation should be 6x+42=18x-12

Add the 12 to both sides to get 6x+54=18x

Move the 6x to the other side to get 54=12x

Then divide by 12 on both sides to get 4.5

Therefore, x=4.5.

love history [14]

Answer:

720, 5040

Step-by-step explanation:

It's always times plus 1. So,
1 x 2 = 2

2 x 3 = 6

6 x 4 = 24

24 x 5 = 120

120 x 6 = 720

720 x 7 = 5040

Lady bird [3.3K]

Answer:

0.04,0.25.0.52

Step-by-step explanation:

Given that you throw a dart at a circular target of radius 10 inches.

Assuming that you hit the target and that the coordinates of the outcomes are chosen at random,

probability that the dart falls

(a) within 2 inches of the center

Here favourable region has area of a circle with radius 2 inches and sample space has area of 10 inches

Prob = \frac{\pi *2^2}{\pi *10^2} \\\\=\frac{1}{25}

(b) within 2 inches of the rim.

For within two inches from the rim we have to select area of the ring i.e. area of big circle with 10 inches - area of smaller circle with 10-2 inches

Prob= \frac{\pi * *8^2}{\pi*10^2} \\=0.64

c) within I quadrant

area of I quadrant / area of circle=0.25

d) within I quadrant and within 2 inches of the rim

= I quadrant area + 2 inches ring area - common area

= \frac{\pi*10^2/4 + pi*(10^2-8^2) - \pi(10^2-8^2)/4}{\pi*10^2} \\=\frac{25+36-9}{100} \\=0.52
