The given expression evaluates to -19.
<h3>What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?</h3>
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
- For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.
We have the following expression -
- 6 - 13
The given expression evaluates to -
x = - 6 - 13
x = - 19
Therefore, the given expression evaluates to -19.

Answer:
it's the last one, and the missing number is 70 (the P)
Answer:
24°
Step-by-step explanation:
Let x = one complementary angle
Let y = the other complementary angle
As the sum of two complementary angles is 90°:
x + y = 90
If one angle is 18° more than two times the other angle:
y = 18 + 2x
Rewrite x + y = 90 to make x the subject:
x = 90 - y
Now substitute x = 90 - y into y = 18 + 2x and solve for y:
y = 18 + 2(90 - y)
⇒ y = 18 + 180 - 2y
⇒ 3y = 198
⇒ y = 198 ÷ 3 = 66
Now substitute found value of y = 66 into x + y = 90 and solve for x:
x + 66 = 90
⇒ x = 90 - 66 = 24
Therefore, the larger angle = 66° and the smaller angle = 24°
Answer:
810
Step-by-step explanation:
21 = 42
Decode:
Number in the tens place = 2 x 2 = 4
Number in the ones place = 1 x 2 = 2
Answer: 42
39 = 618
Decode:
Number in the tens place = 3 x 2 = 6
Number in the ones place = 9 x 2 = 18
Answer: 618
17 = 214
Decode:
Number in the tens place = 1 x 2 = 2
Number in the ones place = 7 x 2 = 14
Answer: 214
Find 45
Number in the tens place = 4 x 2 = 8
Number in the ones place = 5 x 2 = 10
Answer: 810
Answer:
x = 4
Step-by-step explanation:
Solve the inequality
2x - 3 > 11 - 5x ( add 5x to both sides )
7x - 3 > 11 ( add 3 to both sides )
7x > 14 ( divide both sides by 7 )
x > 2
The only value of x greater than 2 is 4, thus
x = 4 is in the solution set
