6(x+2) - x becomes 5x+12
4(x+4)+7 becomes 4x+23
5x+12=4x+23
x=11

<span>6(x + 2) - x = 4(x + 4) + 7
Use distributive property
6x+12-x=4x+16+7
Subtract x from 6x
5x+12=4x+16+7
Add 7 to 16
5x+12=4x+23
Subtract 4x from both sides
x+12=23
Subtract 12 from both sides
Final Answer: x=11</span>

Explain how horizontal and vertical translations each affect the coordinates of the points of a figure?
Neporo4naja [7]
Translations of geometric figures in the coordinate plane can be determined by translating the x- and y-coordinates of points. Horizontal and vertical translations are the easiest. ... Solution: A horizontal translation just changes the x-coordinates of all points, so the rule is (x, y) à (x + 3, y).

There were 6 purple socks and 4 oraange socks without looking and then another without looking (or replacing the first). What is
shusha [124]

Answer:

The probability that he picked 2 purpled socks is <u>0.33</u>.

Step-by-step explanation:

Given:

Number of purple socks, n(P) = 6

Number of orange socks, n(O) = 4

Two socks are picked without replacement.

Now, total number of socks, n(T)=N(P)+n(O)=6+4=10

Probability of picking the first cap as purple cap is given as:

P(P1)=\frac{n(P)}{n(T)}\\\\P(P1)=\frac{6}{10}=\frac{3}{5}

Since there is no replacement, the number of socks decreases by 1. Also, if the first sock picked is purple, then number of purple socks is also decreased by 1.

Therefore, probability of picking the second cap as purple cap is given as:

P(P2)=\frac{n(P)-1}{n(T)-1}\\\\P(P2)=\frac{5}{9}

Now, probability that both the picked caps are purple is given by their probability product. This gives,

P(P1\ and\ P2)=P(P1)\times P(P2)\\\\P(P1\ and\ P2)=\frac{3}{5}\times\frac{5}{9}\\\\P(P1\ and\ P2)=\frac{3}{9}=\frac{1}{3}=0.33

Therefore, the probability that he picked 2 purpled socks is 0.33

Parallel lines s and t are cut by a transversal, r, as shown.
Diano4ka-milaya [45]

Answer:

the value of x is 18

Step-by-step explanation:

observing the figure,

 m < 1 =94 -----> by corresponding angles

(5x-4)+m < =180 degree -----> by supplementary angles

Substitute the measure of angle 1 and solve for x,

(5x-4)+94 = 180 degree

5x=180degree - 90degree

5x=90degree

x=18 degree
