Does anyone know the answer to -8=16x + 9
Answers
Answer:
x = -17/16
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
-8 = 16x + 9
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x[Division Property of Equality] Divide 16 on both sides: -17/16 = xRearrange/Rewrite: x = -17/16Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -8 = 16(-17/16) + 9Multiply: -8 = -17 + 9Add: -8 = -8Here we see that -8 does indeed equal -8.
∴ x = -17/16 is the solution to the equation.

The measure of the side length (that is hypotenuse) of the right-angle triangle will be √202 units.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Let the missing side of this right triangle be х.
Then the measure of the side length (that is hypotenuse) of the right-angle triangle will be
x² = 9² + 11²
x² = 81 + 121
x² = 202
x = √202

Answers
Answer:
517 caixas
Step-by-step explanation:
Em uma fazenda, os ovos são colocados em caixas de 1 dúzia. O número de caixas necessárias para embalar 6.204 ovos é:
1 dúzia = 1
Conseqüentemente:
12 ovos = 1 caixa
6204 ovos = x caixa
Multiplicação cruzada
12 x = 6204 × 1
x = 6204/12
x = 517 caixas

What is the center of the circle for this equation:

Knowing this information, we can deduce that the center of the circle is at

−

)
, and the radius measures 3 units.
x

is a vertical line, while the circle will extend equal length in all direction, in function of it's radius. Looking at the centre and adding 3 to the x value, we get the point
(
9
,
−
2
)
. This point doesn't only lie on the circle; it also lies on the line
x
=
9
. Furthermore, this is the furthest possible distance from the center, so the line will only pass through this one point. Therefore, we can state that the line x = 9 is tangent to

Actual length (ft) _____3 6 9 12 15 18
From the data:
Blueprint : actual
2 in : 3 feets
Length of wall on blueprint = 9 inches
Actual length of wall :
2 inches = 3feets
9 inches = x
Cross multiply
2x = 27
x = 27 /2
x = 13.5 feets

For actual width = 1.5 feets
2 inches = 3feets
x = 1.5 feets
