The answer is A Translations
Answer:
1st option
Step-by-step explanation:
Given the 2 equations
2x + 5y = 19 → (1)
y = 3x - 3 → (2)
Substitute y = 3x - 3 into (1)
2x + 5(3x - 3) = 19
Answer:
Okay!
Step-by-step explanation:
I have simplified the operation, and I got x^2 + 3.
If you wanted me to evaluate, the answer is still x^2 + 3.
If you wanted me to subtract then the answer is again, x^2 + 3.
Basically the answer is x^2 + 3.
Have a good day!
Answer:
80.
Step-by-step explanation:
When multiplying if the tenth place is " 7" then we look " next door" which is the ones and 8 is great then 5 so we count to from 8 to see when the next number ending in 0 would be in this case its 80. ( if the number is 4 or less count backwards to a number ending with 0 which in that case would have been 70 ) but the answer is 80.
ANSWER
The smaller angle is
![y = 36 \degree](https://tex.z-dn.net/?f=y%20%3D%2036%20%5Cdegree)
.EXPLANATION
Let the angles be
![x \: and \: \: y](https://tex.z-dn.net/?f=x%20%5C%3A%20%20and%20%5C%3A%20%20%5C%3A%20y)
where y is the smaller angle.
Since they are supplementary, they will add up to 180°.
This implies that,
![x + y = 180 \degree...(1)](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20180%20%5Cdegree...%281%29)
If one angle is 4 times the other, we can then write the following equation,
![x = 4y...(2)](https://tex.z-dn.net/?f=x%20%3D%204y...%282%29)
We put equation (2) into equation (1) to get,
![4y + y = 180 \degree](https://tex.z-dn.net/?f=4y%20%2B%20y%20%3D%20180%20%5Cdegree)
![5y = 180 \degree](https://tex.z-dn.net/?f=5y%20%3D%20180%20%5Cdegree)
We divide through by 5 to obtain,
![y = 36 \degree](https://tex.z-dn.net/?f=y%20%3D%2036%20%5Cdegree)
This implies that,
![x = 4(36)](https://tex.z-dn.net/?f=x%20%3D%204%2836%29)
