Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
Answer:
The 2 in the hundreths is 10% of the 2 in the tenths
Step-by-step explanation:
We are given the number 15.2201
#The value of 2 in the tenths:
#The value of 2 in the hundredths:
The difference of the 2 in the tenths and in the hundredths is:
Hence, the difference between the 2 in the tenths minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.
3 (2x + 4y - y) Combine like terms (4y and -y)
3 (2x + 3y) Use the Distributive Property [(3 · 2x) + (3 · 3y)]
6x + 9y
