Answer:
x=-37/3
y=-22/3
Step-by-step explanation:
-2x+2y=10 (1)
2x-5y=12 (2)
(1)+(2) <=> -3y=22
Answer:
3:4
The answer is that divide it and multiply it by 2 and 3 respectively
69.99
20% off of 14.99 is 119.992 then -50 is 69.992 but we round to nearest cent and sence 2 is less than five we round down so jt is 69.99$
Answer:
8. Identify the common denominator; express each fraction using that denominator; combine the numerators of those rewritten fractions and express the result over the common denominator. Factor out any common factors from numerator and denominator in your result. (It's exactly the same set of instructions that apply for completely numerical fractions.)
9. As with numerical fractions, multiply the numerator by the inverse of the denominator; cancel common factors from numerator and denominator.
10. The method often recommended is to multiply the equation by a common denominator to eliminate the fractions. Then solve in the usual way. Check all answers. If one of the answers makes your multiplier (common denominator) be zero, it is extraneous. (10a cannot have extraneous solutions; 10b might)
Step-by-step explanation:
For a couple of these, it is helpful to remember that (a-b) = -(b-a).
<h3>8d.</h3>
___
<h3>9b.</h3>
___
<h3>10b.</h3>
Neither solution makes any denominator be zero, so both are good solutions.
Answer:
d) 7 percent
Step-by-step explanation:
Diener and Wallbom in 1976 carried out a research on the effect of self awareness on antinormative behavior. They reported on college students, who when asked, said that cheating was morally wrong. When given a timed IQ test and a chance to work illicitly beyond the time limit, 71% of them did so. The puzzle problems were intentionally set such that most of them will be unsolvable, this is to ensure that success was impossible without cheating.
When they were made to be self aware by introducing a mirror during testing, this rate of those that continued to work was reduced to only 7%. This research centered on the differential use of morality and competence standards for behavior when in a state of self-awareness.
