Solve the equation. Simplify your answer if possible.
-2.1 = 2.5z - 2.6
The solution set is { }

Answer:

21

Step-by-step explanation:

product of 3 number= 1197

1st number= 3

2nd number= 19

3rd number= let,X

Now,

3*19*X= 1197

or, 57*X= 1197

or, X= 1197/57

X= 21

Answer:

(-2, 3)

Step-by-step explanation:

For x-4 you go left four places and y+6 go up 6 places

Answer:

(-2, 3)

Step-by-step explanation:

Point P has coordinates (2, -3).

The translation is (x - 4, y + 6) which means subtract 4 from the x-coordinate and add 6 to the y-coordinate.

The x-coordinate of point P is 2. Subtract 4 from it, you get -2.

The y-coordinate of point P is -3. Add 6 to it to get 3.

The coordinates of the translated point are (-2, 3).

Answer:

No, It is not equal to a 60% discount.

Step-by-step explanation:

Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.

Hope I helped you understand :)

hi <3

i'm not sure of which method you will have been taught but i'll try to explain the method i was shown.

so, you need to multiply the coefficient of x^2 by the last value

3 x -12 = -36

now, you need to find two values that multiply to make -36 but add to make 5.

9 and 4 would work. it would have to be positive 9 and negative 4, as these would subtract to give the 5 that you need

now we have:

(x - 4)(x + 9)

however, we need to achieve the 3 from somewhere so it needs to be divided somewhere

9 is divisible by 3 so you can divide it there. as 4 cannot divide by 3, you would move the 3 up to be the coefficient.

thus, your final answer would be:

(3x - 4)(x + 3)

hope this helps :)

Answer:

it's gonna be 3(X*2 + 4X - 4)

Step-by-step explanation:

Just factor out 3 from the expression

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

Answer:

2.956

Step-by-step explanation:

[tex]\frac{295.6}{10^2}[/tex]

= [tex]\frac{295.6}{100}[/tex]

= 2.956

Answer:

873.7936

Step-by-step explanation:

295.6 divided by 10 is

29.56.

This can be easily done by moving the decimal up one place to the left. For 29.56 to the power of 2 is really just 29.56 * 29.56

29.56 * 29.56 is

873.7936.

Answer:

10:7

Step-by-step explanation:

ratios are simply just like fractions!

this ratio (40:28) can be re-written as 40/28

now, you can simplify this to its lowest terms

40/28=20/14=10/7

first in those steps i re wrote the question, then divided by two, then divided by two again !

so, 40:28=10:7

--------------------------------

you can even check this by cross multiplying, since ratios are fractions

[tex]\frac{40}{28} =\frac{10}{7}[/tex]

40x7=28x10

280=280

they are equivalent which means our ratio is correct :)

Answer:

AC = AB + BC

18 = (2X - 4) + (3X + 2)

18 = 5X - 2 ( add/subtract like terms)

20 = 5X (-2 take over otherside - 18 + 2)

X = 4

SUB X INTO AB AND BC

AB = 2(4) - 4 = 4

BC = 3(4) + 2 = 14

Answer: 170.25

Step-by-step explanation:

Quick version

Step 1: Convert 15 percent to decimal

[tex]15\%\:=\frac{15}{100}\\\\= 15 \%[/tex]

Step 2: Multiply 0.15 to 1135

[tex]0.15\cdot \:1135\\\\=170.25[/tex]

170.25 is 15 percent of 1135.

Answer:

170.25 is the solution.

Step-by-step explanation:

Let's find 15% of 1135.

Value of the percentage is,

→ 15 ÷ 100

→ 0.15

Let's find the solution,

→ 1135 × 0.15

→ 170.25

Thus, the answer is 170.25.

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!

n = 119

Answer:

14810 votes

Step-by-step explanation:

The canidate won, so that means that they were the 7 instead of the 5.

Then you divide 20734 by 7, to see how many votes were for each "1". That's 2962.

Now you know that every "1" is worth 2962. Since the other candidate got 5, you multiply 5 by 2962 which is 14810.

The other candidate got 14810 votes.

Hope that made sense

Answer:

The other opponent that lost got 14 810 votes.
