Answer:

i believe DEC is 70 degrees

Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.

f(x)=10x-4, f(12)= 116

The value of the function f(x) = 10x - 2 at f(12) is 114.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 10x - 4.

To find f(12) we have to replace x with 12 in the function f(x).

∴ f(12) = 10(12) - 4.

f(12) = 120 - 4.

f(12) = 114.

Answer:

Step-by-step explanation

x+38=2(x+14)

The man is 38 and daughter is 14. They both will age in same years (x).

So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?

x+ 38=2(x+14)

x+38=2x+ 28

10= x

In 10 years, the man will be 2twice as old as his daughter.

Answer:

3/4

Step-by-step explanation:

To find slope, the equation is y(2)-y(1)/x(2)-x(1). So, your equation would look like: 8-5/1-(-3), which equals 3/4. Therefore, 3/4 is your answer.

Answer: 180

Step-by-step explanation:

When added together, Interior angles of a triangle are always equal to 180 degrees.

Answer:

∠FHG=120°

Step-by-step explanation:

first you calculate the angles of the triangle NGH

this is isoceles triangle, so there's 2 equal angles

and as shown, the 2 same angles are having 2 lines in each one, this 2 lines represents that the 2 angles are same

so both are 20°

any triangle has a sum of 180° of interior angles

so 180-(H+G)=the angle below N

180-(20+20)=140°

the angle below N is same as N because they're vertically opposite

140 is an exterior angle

and the exterior angle is equal to the 2 far angles

140=40+∠FHN

140-40=100°

so ∠FHN=100°

∠FHN+∠NHG=∠FHG

100+20=120°

so ∠FHG=120°

one 20 inch pizza

Step-by-step explanation:

radius of one 10 inch pizza is 10/2 = 5

so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]

there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]

Step-by-step explanation:

It would appear that the numbers are increasing in multiples of 2.

15 * 2 = 30

30 * 2 = 60

The next 3 terms will therefore be:

60 * 2 = 120

120 * 2 = 240

240 * 2 = 480

Answer:

Carter will sell 17 bags of peaches before he restocks.

Step-by-step explanation:

Total pounds of peaches Carter have = [tex]25\frac{1}{2} = \frac{51}{2} = 25.5[/tex]

Weight of each bag = [tex]1\frac{1}{2} = \frac{3}{2} = 1.5[/tex] pound

Number of bag made = [tex]\frac{25.5}{1.5}[/tex]  = 17

The number is fully divided , it means no of peaches left = 0 < 3

So,

Carter will sell 17 bags of peaches before he restocks.

The number of bas of peaches, b, Carter will sell before he restocks is 17.

Since he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left.

So here

[tex]= 25.5 \div 1.5[/tex]

= 17

Answer:

first number = 8

second number = -5

Step-by-step explanation:

Let

x = first number

y = second number

Two numbers have a difference of 13.

x - y = 13

The sum of twice one number and 3 times the other number is 1

2x + 3y = 1

x - y = 13 (1)

2x + 3y = 1. (2)

From (1)

x = 13 + y

Substitute into (2)

2x + 3y = 1.

2(13 + y) + 3y = 1

26 + 2y + 3y = 1

26 + 5y = 1

5y = 1 - 26

5y = -25

y = -25/5

y = -5

Substitute y = -5 into (1)

x - y = 13

x - (-5) = 13

x + 5 = 13

x = 13 - 5

x = 8

The obtained number is 12. And the system of equations is 2c + 4p = 40

Although each chicken has two legs and each pig has four legs, the total number of animal legs is:

2c + 4p = 40

Once we simplify the above equation, we get

c + 2p = 20

We also know that there are 16 animal heads in total, which can be expressed as:

c + p = 16

We can solve for "c" that use these two equations.

Once we multiply the second equation by 2, we get:

2c + 2p = 32

Once we subtract this equation from that, we get:

2p = 8

Once we solve for "p," we get:

p = 4

Substituting this "p" value into the second equation yields:

c + 4 = 16

Once we solve for "c," we get:

c = 12

As an outcome, your parents hold 12 chickens.
