Answer:

2a: 5

2b: 7

2c: 10

2d: 2

2e: 3

2f: 2

Step-by-step explanation:

To solve all of these you just get the variable (x) by itself

2A: 9x-41=39-7x

Add 7x from both sides and then add 41 to get

16x=80

Divide by 16 and get x=5

2B: 3x-13=50-6x It's the same process as before for this question

Add 6x and 13 to both sides to get

9x=63

divide by 9 and get x=7

2C: 5x-17=83-5x

Add 5x and 17 to both sides

10x=100

divide by 10

x=10

2d: 13x-16=24-7x

Add 7x and 16 to both sides to get

20x=40

divide by 20 and get x=2

2e: 12x-13=53-10x

Add 10x and 13 to both sides to get

22x=66

divide by 22 and get x=3

2f: 17x-21=51-19x

Add 19x and 21 to both sides and get

36x=72

divide by 36 and get x=2

Use your calculator to find a six decimal approximation for log base (6/3) of 6.8

Natali5045456 [20]

Answer:

Step-by-step explanation:

6.8 = (6/5)^x

6.8 = 1.2^x

x ln 1.2 = ln 6.8

x = ln 6.8 / ln 1.2

= 10.513966

At Maddison high school each student studies one foreign language is 3/5 take Spanish and one-fourth of the remaining take germa

Snezhnost [94]

Answer:

Step-by-step explanation:

3/5 = 0.6

1 - 0.6 = 0.4 students left

Multiply the amount of students remaining by the fractional amount that take German

0.4 x 1/4 = 0.1

1 - 0.6 - 0.1 = 0.3

0.3 x 100 = 30%

Therefore 30% of students take French

Suppose that the probability density function for the length x in feet of some type of fish caught by sport fishermen is given b

Firdavs [7]

Answer:

The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.

Step-by-step explanation:

The probability density function or p.d.f. for the length <em>x,</em> in feet, of some type of fish caught by sport fishermen is :

$p(x) = \left \{{{(\frac{1}{4})\ ;\ 0\leq x\leq 4 } \atop{0\ ;\ otherwise} \right.$

The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is:

$P(0.25\leq X\leq 2)=\int\limits^{0.25}_{2} {(\frac{1}{4})} \, dx \\=|(\frac{1}{4})x|^{2}_{0.25}\\=(\frac{1}{4})(2-0.25)\\=0.4375$

Thus, the probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.

What is x equal to ?

rewona [7]

Triangles are congruent
so
4x + 1 = 13
4x = 12
x = 3

In case you need to find y
2x + y = 8x - 2y
2(3) + y = 8(3) - 2y
6 + y = 24 - 2y
3y = 18
y = 6
