The answer is 12. I got it by dividing 2/3 into 8. I used keep change flip. First I made 8 a fraction by putting one as it's denominator. Then I changed division to multiplication. After that, I flipped the fraction from 2/3 to 3/2. Then I multiplied across. My answer was 24/2. I simplified and got my final answer of 12.
Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).
In a number line which goes from north to south, the upper portion has positive numbers and the lower portion has negative numbers.
so the elevation at Mt. McKinley will be written as +20,236
and at death valley it will be -282
Answer:
x = -4 ±3
x = -7,-1
Step-by-step explanation:
x^2 + 8x = -7
1/2 B ^ 2 = 16
x^2 + 8x + 16 = 16 -7
(x + 4) ^2 = 9
x + 4 = ±3
x = -4 ±3
x = -7,-1
