Angle 2 and 3 is congruent by Substitution Property
Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value <em>y</em>. We can replace the x in the second equation with 11 + y, since we are told in the <em>first</em> equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the <em>first</em> equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!
Answer:
22.5 cm²
Step-by-step explanation:
La fórmula para el volumen de un prisma con una base hexagonal = Área de la base × Altura
De la pregunta anterior
Área de la base =?
Altura = 3 cm
Volumen = 67.5 cm³
Área de la base = Volumen ÷ Altura
Área de la base = 67.5 cm³ ÷ 3cm
= 22.5 cm²
Por lo tanto, el área si es base = 22.5 cm²
Hello!
Point F is between points E and G
This means that the whole line is segment EG
We can make the equation
EF + FG = EG
Put in the values you know
19x - 13 + 11x = 18x + 20
Combine like terms
30x - 13 = 18x + 20
Subtract 18x from both sides
12x - 13 = 20
Add 13 to both sides
12x = 33
Divide both sides by 12
x = 2.75
Put x into the equation for EG
18(2.75) + 20 = EG
Multiply
49.5 + 20 = EG
Add
69.5 = EG
It says to write it as a mixed number
The answer is
Hope this helps!
