Answers

Answer 1

Answer:

6/4y - 12 = 1/2y -4

3/2y -12 = 1/2y - 4

-1/2y          -1/2y

2/2y - 12 = -4           (2/2 = 1)

y - 12 = -4

+12      +12

y = 8

Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
a7=___

Answers

Answer:

Thus: a7=-1

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

We know: a12=29, a16=53, thus

[tex]a_1+(12-1)r=29[/tex]

[tex]a_1+(16-1)r=53[/tex]

Simplifying:

[tex]a_1+11r=29[/tex]

[tex]a_1+15r=53[/tex]

Subtracting both equations:

[tex]4r=53-29=24[/tex]

Solving:

[tex]r=24/4[/tex]

r=6

The 7th term can be found as 5 terms before the 12nd:

[tex]a_7=a_{12}-5r[/tex]

[tex]a_7=29-5*6=29-30=-1[/tex]

Thus: a7=-1

5x + x = 50 - 2

6x = 48

x = 8

if you wanna check it,

5x + 2 = 50 - x

5(8) + 2 = 50 - 8

2x+2a=4b solve for a

Answers

Answer:

a=2b-x

Step-by-step explanation:

Simplifying
2x + 2a = 4b

Reorder the terms:
2a + 2x = 4b

Solving
2a + 2x = 4b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x

Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x

Divide each side by '2'.
a = 2b + -1x

Simplifying
a = 2b + -1x

x = -17

Step-by-step explanation:

x = smallest

x + (x+1) + (x+2) + (x+3) = -62

4x +6 = -62

Which values of a, b, and c correctly complete the division? One-fourth divided by StartFraction 5 Over 6 EndFraction = StartFraction 1 Over a EndFraction times StartFraction b Over c EndFraction a = 4, b = 5, c = 6 a = 1, b = 6, c = 5 a = 1, b = 5, c = 6 a = 4, b = 6, c = 5

Answers

Answer:

a = 4, b = 6 and c = 5

Step-by-step explanation:

It is given that,

[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

We know that,

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

If we compare both sides of the equation we get,

a = 4, b = 6 and c = 5

Hence, these are the values of a,b and c.

The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?

Answers

Answer: 238

Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.

Answer:

232 students are enrolled this year.

Step-by-step explanation:

Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.

[tex]280*0.15=42[/tex]

This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.

280 - 42 = 232

Step-by-step explanation:

In order to solve this, we need to use point-slope form.:

y - y1 = m(x - x1)

Substitute the numbers into the equation:

y - (-8) = 1(x - 0)

y + 8 = x

y = x - 8
