What is the value of x in 2(5x) = 14?
A.
0.34

B.
1.15

C.
1.21

D.
219.33

Answer:

2.57

Step-by-step explanation:

3x²-5x-7=0

Eqn and u will get the answer

we have,

14x+8+6x+12=180 {interior angle}

or, 20x+20= 180

or, 20x= 180- 20

or, x= 160/20

:. x= 8

Now,

14x+8= 14.8+8

= 112+8 =120

6x+12= 6.8+12

= 48+12 = 60

Answer:

f(4) = 0

Step-by-step explanation:

If the value of x is between 0 and 5, then the f(x) will equal 0.

x = 4 is greater than 0 and less than 5, so f(4) = 0

Answer:

-69

Step-by-step explanation:

6(-4) + (-5)9

= -69

Answer:-69

Step-by-step explanation:

Step-by-step explanation:

Sum of supplementary angle = 180⁰

2x + 12 + 7x - 3 = 180

9x + 9 = 180

9x = 180 - 7

9x = 171

x = 171/9

x = 19

m<3 = 7(19) - 3 = 133 - 3 = 130⁰

m<4 = 2(19) + 12 = 50⁰

Step 2; 3x9=23 5x 3x+ 9=23- 5x

Step 3 ; 3x-9 3x4-9 = 3ft

3ft is the answer.

Answer:

v² - 4

Step-by-step explanation:

To simplify usually means to reduce something.

So like in this problem all we have to do is reduce...

v^2 - 2^2

v² - 4

Answer:

48 inches

or

0.8 minutes

Step-by-step explanation:

To find the unit rate of inches per hour, divide 144 by 3.

144÷3=48

You don't need to round because there are no decimals.

To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).

3×60=180

Then divide 144 by 180.

144÷180= 0.8

You don't need to round because there are no thousandths.

Answer:she will have 4.44 ounces of cornstarch left

Step-by-step explanation: 1 pound=16 ounces 16*5=80 ounces 80 ounces equal 5 pounds then you divide 80 by 18 and your answer should come out as 4.44 ounces

Amount of cornstarch left is 8 ounce

Given that;

Each student get = 4 ounce of cornstarch

Total number of student = 18 students

Total amount of cornstarch = 5 pound

Find:

Amount of cornstarch left

Computation:

Amount of total cornstarch to student = Each student get × Total number of student

Amount of total cornstarch to student = 4 × 18

Amount of total cornstarch to student = 72 ounce

1 pound = 16 ounces

So,

Total amount of cornstarch = 5 × 16

Total amount of cornstarch = 80 ounces

Amount of cornstarch left = 80 - 72

Amount of cornstarch left = 8 ounce

Answer:

Step-by-step explanation:

-3y=-3x+15

y=x-5

make x=0

y=0-5

y=-5

There are many examples to pick from, but one example is this:

The set of rational numbers (aka any fraction of two integers) is closed under the operation of division. Divide any two rational numbers and we get some other rational number.

However, the set of integers is not closed under division. If we divided 10 over 3, then we get 10/3 = 3.333 approximately which isn't an integer. So just because the set of integers is a subset of the rationals, it doesn't mean that the idea of closure follows suit from superset to subset.  

Side note: The term "superset" is basically the reverse of a subset. If A is a subset of B, then B is a superset of A.

Answer:

Step-by-step explanation:

a^6 = a * a * a * a * a * a You can break this into groups of 2 and groups of three.

Groups of 3

a^6 = a * a * a * a * a * a

what that means is that you have 2 groups of 3 which can be written as (a^3)^2 which means that this number is a perfect square.

Groups of 2

a^6 = a * a * a * a * a * a

What this means is that you have (a^2)^3 which is three groups of 2 members. The answer is that you have a perfect cube each member of which is a^2

Answer:

The function is decreasing.

Step-by-step explanation:

f(x) = x is the parent function, when you make x negative it decreases rather than increasing. the use of the slope (1/2) doesn't change whether it it increasing or decreasing. as long as the negative sign is in front, it will decrease.
