Answer:
Y = 2
X = 3
Step-by-step explanation:
Substitution:
6(4y-5) - y = 16
24y-30-y=16
23y=46
Y = 2
So then:
6x-2 = 16
6x = 18
X = 3
Steps to solve for the zero:
(x + 7)(x + 5) = 0
~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
~Solve for x in [ x + 5 = 0 ]
x + 5 = 0
x + 5 - 5 = 0 - 5
x = -5
Therefore, the solutions are x = -7 and x = -5
Best of Luck!
ANSWER:
70, 000
67, 000 rounded to the nearest ten thousand is: 70, 000.
EXPLANATION:
As we are rounding the number to the nearest ten thousand, we will look at the thousand digit of the number in order to decide whether to round the number up or down. As the thousand digit is 7, we must round the ten thousand digit up meaning that the 6 would become a 7. Therefore, the answer would be 70, 000.
Answer:
4+-2
Step-by-step explanation:
Answer:
5 1/10 c or 3 1/10 +2
When you simplify the expression, you combine like terms. 5 7/10 c and -2 3/5 c are like terms. You multiply two on the numerator and denominator to make it 6/10. You subtract 2 6/10c from 5 7/10c to make it 3 1/10. This next step is easy. 8 and -6 are like terms. So you subtract 6 from 8 to get two. The final step is optional. 3 1/10 + 2= 5 1/10
