What equals 2а + 3c. ​

Answer:

z = 5

Step-by-step explanation:

divide both sides of the equation by -0.25

[tex]-0.25z = -1.25[/tex], original equation

[tex]\frac{-0.25z}{-0.25} =\frac{-1.25}{-0.25}[/tex], divide both sides by -0.25, solve for -1.25 ÷ -0.25 = 5

[tex]z = 5[/tex], final answer

Answer:

sin C = 40/41

cos C = 9/41

tan C = 40/9

Step-by-step explanation:

sin C = opp/hyp = c/b = 40/41

cos C = adj/hyp = a/b = 9/41

tan C = opp/adj = c/a = 40/9

Answer: the answer is a (16+14)÷ 4

Step-by-step explanation:

The expression to represent the given phrase is is (6+14)÷4.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The given phrase is the sum of 6 and 14 and divide by 4.

Variables and constants are combined to generate algebraic expressions using a variety of techniques. Terms comprise expressions. A term is the sum of several elements. Factors might be algebraic or numerical (literal).

Here, the sum of 6 and 14 is

6+14 =20

The sum is divided by 4.

So, 20/4 =5

Then the expression is (6+14)÷4

Therefore, the expression to represent the given statement is (6+14)÷4.

Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)

Answer:

it is 380 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

10^3=10(10)10=1000

1000(0.38)=380

Step-by-step explanation:

i think you just have to subtract 460-187 equals 273 so he can put 273 or something lower then that

Answer:

D

Step-by-step explanation:

Answer: D

The first option is incorrect because 56+angle 3=180 and when you solve it angle 3 equals 124 degrees, not 142 degrees

The second option is incorrect because 56+43+angle 1=180 (because all triangles add up to 180 degrees). When you solve that angle 1 equals 81 degrees, not 99 degrees

The third option is incorrect because angle 1+angle 2=180, and we already know angle 1 equals 81, so when you solve that angle 2 equals 99 degrees, not 137 degrees. So we know the last option is correct.

But if you want to make sure it's correct, you can always solve for angle 4. Angle 4+43=180 degrees, and when you solve it, angle 4 equals 137 degrees, and we know that option is correct.

Hope this helped you!
