Answer: Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol

Answer:

x = 16

Step-by-step explanation:

The triangle in question is an isosceles triangle which means :

m<Q = m<P and the sum of interior angles in a triangle is equal to 180

so we can find the value of x using the following equation:

5x - 2 + 3x + 3 + 3x + 3 = 180 add like terms

11x + 4 = 180 subtract 4 from both sides

11x = 176 divide both sides by 11

x = 16

the angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

kvv77 [185]

Answer:

x =17.6

The three angles are

6x = 105.6

x-3 =14.6

3x+7 = 59.8

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

6x + x-3 + 3x+7 = 180

Combine like terms

10x +4 = 180

Subtract 4 from each side

10x+4-4= 180-4

10x = 176

Divide each side by 10

10x/10 =176/10

x =17.6

The three angles are

6x = 6*17.6= 105.6

x-3 = 17.6-3 =14.6

and 3x+7 = 3(17.6)+7 =52.8+7 = 59.8

Which statement about the values 0.034 and 3.40 are true

Nana76 [90]

Answer:

See Explanation

Step-by-step explanation:

This question requires options.

Since none is provided, I will give a general solution.

We have: 0.034 and 3.40

Required

The relationship between them

3.40 can be expressed as:

$3.40 \to 0.034 * 100$

This means that 3.40 is 100 of 0.034

Similarly, 0.034 can be expressed as:

$0.034 \to 3.40 * \frac{1}{100}$

This means that 0.034 is 1/100 of 3.40

Solve each system of equations (show steps) y=2x x+y=12

Hunter-Best [27]

Im learning this too right now hope this helps

1.you get y by itself and put what y equals where y is in the other equation
y=2x. x+y=12

x+2x=12
3x=12. (divided 3 on both sides)
x=4

2.after you find x(or y) put it in one of the problems above and solve for whats missing which in this case is y

y=2(4) 4+y=12
y=8. -4. -4
y=8
