Answer:
2x + 20 = -60
-20 -20
2x = -80
Divide by 2 on both sides.
X = -40
Answer:
-40
Step-by-step explanation:
2(x + 10) = -60
step 1 distribute the 2 to the x and 10
2 * x = 2x
2 * 10 = 20
we now have 20 + 2x = -60
step 2 subtract 20 from each side
20 - 20 cancels out
-60 - 20 = -80
we now have 2x = -80
step 3 divide each side by 2
2x / 2 = x
-80 / 2 = -40
we're left with x = -40

Use a half-angle identity to find the exact value of cos 15º.
Answer:
Step-by-step explanation:
[tex]cos15=cos\frac{30}{2}[/tex] so the angle we will use in our identity is 30 degrees. The formula is
[tex]cos\frac{30}{2}=\sqrt{\frac{1+cos30}{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{1+\frac{\sqrt{3} }{2} }{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{\frac{2+\sqrt{3} }{2} }{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{2+\sqrt{3} }{4} }[/tex] which simplifies, finally, to
[tex]\frac{\sqrt{2+\sqrt{3} } }{2}[/tex], choice a.

Answer:
y = 4/3x - 2, B is your answer
Step-by-step explanation:
Y intercept is the number next to slope(b).
The co efficient of x will be your slope so therefore the co efficient of x will be 4/3
y is always there because it will always be the dependent variable on the left side.
Answer:
the answer is B
Step-by-step explanation:
Y=(slope)x+y-intercept/y=mx+b
plug in the slope then the Yy intercept

What is the missing number in the pattern? 9, _____, 35, 48, 61
Answer:
4 there all adding by 13 so do 13-9 to get 4
Answer: 22
Step-by-step explanation: The answer is 22 because all you have to do it keep adding 13 to the number like.
9 + 13 = 22
22 + 13 = 35
35 + 13 = 48
48 + 13 = 61

The diagram shows two rectangles which have the same area . Find the value of y.
Answer:
y = 4
Step-by-step explanation:
Since the 2 rectangles have the same area, then
12.5 × 2y = 5 × 20
25y = 100 ( divide both sides by 25 )
y = 4

Hamdan bought a TV for 40000 and sold it for 32000. What is the profit/loss percentage
Answer:
20% loss
Step-by-step explanation:
(32000-40000)/40000 * 100 = -20%
Answer:
Step-by-step explanation:
CP of a TV=40000
Sp of a TV=32000
here CP is greater than Sp so there is loss
loss=CP-SP
=40000-32000
=8000
loss%=loss amount/cp*100%
=8000/40000*100
=800000/40000
=20%

Question above
Answer:
6,561
Step-by-step explanation:
Given that;
[tex]log_3x + log_9x = 12\\log_3x+1/2log_3 x = 12\\(1+1/2)log_3x = 12\\3/2log_3x = 12\\log_3x = 12 *2/3\\log_3x = 8\\x = 3^8\\x = 6,561[/tex]
Hence the value of x is 6,561

Patrice, por sí solo, puede pintar cuatro cuartos en 10 horas. Si contrata a April para que le ayude, pueden hacer el mismo trabajo en 6 horas. ¿Cuánto tiempo le tomará a April pintar cuatro cuartos si trabaja sola?
Answer:
15 horas
Step-by-step explanation:
Representemos:
El número de horas que Patrice puede pintar solo = P = 10 horas
El número de horas que April puede pintar por su cuenta = A = X horas
El número total de horas que pueden trabajar juntos para hacer el mismo trabajo = T = 6
Por tanto, nuestra fórmula es:
1 / P + 1 / A = 1 / T
1/10 + 1 / A = 1/6
1 / A = 1/6 -1/10
Denominador común más bajo = 30
1 / A = 5 - 3/30
1 / A = 2/30
1 / A = 1/15
Multiplicar cruzada
A × 1 = 15 × 1
A = 15 horas
Por lo tanto, la cantidad de horas que April puede pintar cuatro habitaciones si trabaja sola es de 15 horas.
