Answer:

the Ans is 3.4

Step-by-step explanation:

8(3x - 7) = -6(x + 7) + 4

24 x – 56 = -6x - 42 + 4

24x - 56 = -6x + 46

30 x = 102

X=3.4

Answer:

-6u + 7

Step-by-Step Explanation:

Rearrange Terms:

(8 - u) - 1(5u + 1)

(-u + 8) - 1(5u + 1)

Distribute:

(-u + 8) - 1(5u + 1)

(-u + 8) - 5u - 1

Eliminate Redundant Parentheses:

(-u + 8) - 5u - 1

-u + 8 - 5u - 1

Subtract the Numbers:

-u + 8 - 5u - 1

-u + 7 - 5u

Combine Like Terms

-u + 7 - 5u

-6u + 7

Solution:

-6u + 7

Answer:

1/3−1/2=− -1/6

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1....Complete the multiplication and the equation becomes ....The two fractions now have like denominators so you can subtract the numerators. This fraction cannot be reduced.....and that's how i got the answer

Answer:

= 2x(x + 3)

Answer:

140p calories

Step-by-step explanation:

Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is

8 * 1.25 = 10 miles

Therefore, Bianca jogged a total of 10 miles the previous month.

Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.

If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.

Therefore, we conclude that Bianca burnt 1400 calories.

Answer:

Step-by-step explanation:

SOH CAH TOA

use the trigonometry mnemonic (new monic)  to help remember how sin cos and tan fit on the triangle

since you know the angle and you want to know the side opposite of that angle... and you know the side adjacent ( next to) the angle... use Tan

use the mnemonic to help

Tan(Ф)= Opp/ Adj  ( we know two of these things and we want the 3rd :P )

Adj * Tan(25) = Opp

250 * Tan(25) = Opp

116.5769.... = Opp

x = 116.6  ft. approx. in the picture

Answer:

option (3) is right answer

Answer: 14. x = 16; y = 23

15. x = 9; y = 13

Step-by-step explanation:

14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)

4x + 4 = 7x - 44

Collect like terms

4x - 7x = -4 - 44

-3x = -48

Divide both sides by -3

x = -48/-3

x = 16

39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)

39 + 8y - 43 = 180

Add like terms

-4 + 8y = 180

Add 4 to both sides

8y = 180 + 4

8y = 184

Divide both sides by 8

y = 184/8

y = 23

15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)

15x - 26 = 12x + 1

Collect like terms

15x - 12x = 26 + 1

3x = 27

Divide both sides by 3

x = 27/3

x = 9

28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)

Plug in the value of x

28 + 12(9) + 1 + 4y - 9 = 180

28 + 108 + 1 + 4y - 9 = 180

Add like terms

128 + 4y = 180

Subtract 128 from each side of the equation

4y = 180 - 128

4y = 52

Divide both sides by 4

y = 52/4

y = 13

Both answer and explantion.

A. is the correct answer

Step-by-step explanation:

Answer:

x=6 y=-7

Step-by-step explanation:

rearrange the equation

3y=x-27 eq 1

2y=-4x+10 eq 2

Multiply eq 1 by 2, and eq 2 by 3

6y=2x-54

6y=-12x+30 subtract the two eq's

0=14x-84

84=14x

x=84÷14

x=6

solving for y sub. x either eq 1 or 2

3y=x-27

3y=6-27

3y=-21

y=-21÷3

y=-7

Answer:

20% of 150 is 30 :)

Step-by-step explanation:

Answer: original price = p

price after first 24% discount = .75p

he second 25% discount reduces the already reduced price to .75*.75p = .5625p

So, if .5625p = 16,

p = 16/.5625 = $28.44

check:

25% off $28.44 = $21.33

25% off $21.33 = $16.00

Answer:

defines y as a function of x, because for every x value there is no more than a y value. (In fact for every x there is exactly one y value). We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.

x=y2+6  does not define y as a function of x, because some value(s) of x have more than one y.

In general,

       x=y2-6--->x+6=y2

So, all the values of x larger than -6 would have two y values.

For example, x=10 would be paired with y=4 and y=-4.

A function cannot assign more than one y to any x value.

Answer:

A

Step-by-step explanation:

To answer this, we need to see what happens to the curves on the given interval

For f(x), we have that there is a decrease as we are moving from a higher positive value of y to a lower positive value of y over the specified interval

For g(x), we can see that we are moving from a lower positive y value to a higher positive y value

What this mean is that the first option is correct

Answer:

m=7

Step-by-step explanation:

15m−13m=69.96−55.96

Step 1: Simplify both sides of the equation.

15m−13m=69.96−55.96

15m+−13m=69.96+−55.96

(15m+−13m)=(69.96+−55.96)(Combine Like Terms)

2m=14

2m=14

Step 2: Divide both sides by 2.

2m

2

=

14
