Answer:
<em>-5</em>
Step-by-step explanation:
-31=9+8x
we need to isolate the variable by moving 8x to the left side and -31 to the right side....therefore 8x becomes a negative, -8x, and -31 a positive....so now it would look like...
-8x=9+31
then we work the right side out...
-8x=40
to get x we need to divide -8x by 8 so we do the same to the right side as well....
-8x=40
÷8 ÷8
so...
<em>x=-5</em>
hope this helped you- have a good day bro cya)
5 1/2 * 3 1/4
1 + 5 . 2/2 * 1 + 3 . 4/4 = 11/2 * 13/4 = 11 . 13/2 . 4 = 143/8 = 7 + 17 . 8/8 = 17 7/8
= 17 . 875
Detailed explanation of solution:
5 1/2 * 3 1/4
Transform the first mix number to improper fraction:
5 1/2 = 1 + 5 . 2/2 = 11/2
Transform the second mix number to improper fraction:
3 1/4 = 1 + 3. 4/4 = 13/4
Multiplying two fractions:
11/2 * 13/4 = 11 . 13/2 . 4 = 143/8
Since the numerator is greater than the denominator, We convert the improper fraction to mix fraction:
143/8 = 7 + 17.8/8
= 17 7/8 (Decimal: 17. 875)
Hope that helps!!!!!! ( Answer: 17 7/8, (Decimal: 17.875)
Answer:
$18,781.5
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Loan amount (P) = $15,000
Rate of interest (r) = 23%
Time (t) = 5 years
Let this loan is compounding annually, then the amount after 5 years can be calculated as follows,
Final amount = P 
by putting the value in formula, we get
= $15,000 ( 
= $15,000 × 1.2521
= $18,781.5
Answer:
Step-by-step explanation:
y ∞ x/m
y = kx/m
Where k is the constant of proportionality
A. k = ym/x
y=5 when x=7 and m=4
k = (5×4)/7
k = 20/7
y = 20x/7m
B)the value of when x=2and m=2
y = 20x/7m
y = (20×2)/(7×2)
y = 40/14
y = 20/7
y = 2 6/7
C. The value of m when y=2 and x=4
y = 20x/7m
7ym = 20x
m = 20x/7y
m = (20×4)/(7×2)
m = 80/14
m = 40/7
m = 5 5/7
