Answer:
a = - 17
Step-by-step explanation:
5+2a = -29
2a = -29-5
2a = - 34
a = -34/2
a = -17
Answer:
6.05, 6.10, 6.50 6.9
Step-by-step explanation:
Since each digit in the ones place are the same and the tenths place are different, look at the tenths place. If the digit in the tenth is larger than the rest, then it is greater than all numbers.
You would do the exact same steps for each place number (tenths, hundredths, ones, tens, etc.)
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 5y = 9 → (1)
3x + 4y = 2 → (2)
Multiplying (1) by 4 and (2) by 5 and adding the result will eliminate the y- term
8x - 20y = 36 → (3)
15x + 20y = 10 → (4)
Add (3) and (4) term by term to eliminate y
23x + 0 = 46
23x = 46 ( divide both sides by 23 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
3(2) + 4y = 2
6 + 4y = 2 ( subtract 6 from both sides )
4y = - 4 ( divide both sides by 4 )
y = - 1
solution is (2, - 1 )
