Answer:
74
Step-by-step explanation:
because it is alternate angle
Answer:
1. 106º
2. 146º
Step-by-step explanation:
1. The two angle are supplementary which means that together they will equal 180º
2. The acute angle next to the angle in question is completing the 180º of both the triangle and the line meaning that the 90º of the triangle plus 56º of the other angle must be the same amount of degrees as angle x.

Answer:
Fourth choice, 16
Step-by-step explanation:
The 2 angles are both 74 degrees, so the side that is facing each angle will be the same length, so:
9x - 73 = 3x + 23
add 73 to both sides
9x = 3x + 96
subtract 3x from both sides
6x = 96
divide by 6
x = 16

Multiply (use the distributive property): 4(x-3)
Pls don't mess around I need this
Step-by-step explanation:
you need to mulitiply the 4 to x and -3
4x-12
if you need to solve for x: 4x=12
X=3
The answer is 4x-12
if you multiply 4 times x it is 4x, and if you multiply 4 by negative 3(-3) the answer is negative 12 (-12), so you put 4x together with -12 that would be 4x-12

Five times the sum of a number and six is equal to three times the difference of a number and ten.
Answer: 6x + 6
Step-by-step explanation:x = the number 5x + (x + 6) {five times the number added to the sum of the number and six} = 5x + x + 6 {took out parentheses}
How do you expand and simplify :
(x+3)^2
Answer: x^2 + 6x + 9

True
Step-by-step explanation:
[50 pts] An even number, n, times the next consecutive number, n + 2, is equal to 168. Find the original number.
We are given:
An even number 'n', multiplied by the next consecutive even number is 168
Solving for n:
From the given statement, we can say that:
n(n+2) = 168 [n multiplied by the next even number 'n+2']
n² + 2n = 168
n² + 2n - 168 = 0 [subtracting 168 from both sides]
We can see that we now have a quadratic equation, solving using splitting the middle term
n² + 14n - 12n - 168 = 0
n(n + 14) -12(n + 14) = 0 [factoring out common terms]
(n-12)(n+14) = 0
Here, we can divide both sides by either (n-12) OR (n+14)
Checking the result in both the cases:
(n + 14) = 0/(n-12) (n-12) = 0/(n+14)
n + 14 = 0 n - 12 = 0
n = -14 n = 12
Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

Answer:
8.246 units long
2sqrt(17) units long in simplest radical form
Step-by-step explanation:
Use the Pythagorean Theorem to find the missing leg length:
a^2+b^2=c^2
4^2+b^2=sqrt(84)^2
16+b^2=84
b^2=68
b=sqrt(68)
b=2sqrt(17) <-- Simplest Radical Form
b=8.246
So the third side is approximately 8.246 units long
Henry runs each lap in 4 minutes. He will run at most 11 laps today. What are the possible numbers of minutes he will run today?
Answer:
Step-by-step explanation:
Time taken in each lap = 4 min
Total laps = 11
Total time = 11 x 4 = 44min
Answer:
44 minutes
Step-by-step explanation:
4 minutes per lap . He is running 11 laps. Multiply 4 times 11 and it equals 44
What is the value of x in the equation 3- 2x = -1.5х?
Answer:
x = 6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3 - 2x = -1.5x
Step 2: Solve for x
Add 2x on both sides: 3 = 0.5xDivide 0.5 on both sides: 6 = xRewrite: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3 - 2(6) = -1.5(6)Multiply: 3 - 12 = -9Subtract: -9 = -9Here we see that -9 does indeed equal -9.
∴ x = 6 is the solution to the equation.
Answer:
x= 6
Step-by-step explanation:
3-2x= -1.5x
-3 -3
-2x= -1.5x - 3
+1.5x +1.5x
-.5x= -3
divide both sides by -.5
x = 6

Answer:
x = 20
Step-by-step explanation:
The length of the segment EG can be obtained as the sum of the segments EF and FG, that is:
EG = EF + FG
We are given:
EF = 4x + 14
FG = 50
EG = 144
Thus, we set the equation:
144 = 4x + 14 + 50
Simplifying:
144 = 4x + 64
Subtracting 64:
80 = 4x
Dividing by 4:
x = 80/4 = 20
x = 20
