Hello!
You put in the know values for x or y
------------------------------------------------------------------------------------------------------
(-6, ?)
We know that x is -6
6y + 5(-6) = -30
Combine like terms
6y + -30 = -30
Add 30 to both sides
6y = 0
y = 0
------------------------------------------------------------------------------------------------------
(?, 5)
We know that y is 5
6(5) + 5x = -30
Combine like terms
30 + 5x = -30
Subtract 30 from both sides
5x = -60
Divide both sides by 5
x = -12
------------------------------------------------------------------------------------------------------
The answers are (-6, 0) and (-12, 5)
Hope this helps!
Answer:62∘
Step-by-step explanation:
SOH-CAH-TOA
\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{2.2}{4.7}
cosU=
hypotenuse
adjacent
=
4.7
2.2
\cos U = \frac{2.2}{4.7}
cosU=
4.7
2.2
U=\cos^{-1}(\frac{2.2}{4.7})
U=cos
−1
(
4.7
2.2
)
U=62.09\approx 62^{\circ}
U=62.09≈62
∘
Find the area of each face and add them all together, or since a cube has 6 faces, you can multiply the area of one face by 6.
Hello,
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!
