Answer:
20 X 40 = 800 (split into 2 fourths) = 40
Step-by-step explanation
20 x 40 = 800;
For 2 necklaces she can split 800 into fourths.
800 - 40 = 80. (1 fourth)
80 - 40 = 40 (2 fourths)
40 - 40 = 0 (3 fourths)
She could split 800 into 2 fourths to get a number more than 0 and less then 42.
The best estimate of rounding 42 is 40. Because 40 is closer to 42.
Answer:
$234 771.75
Step-by-step explanation:
Data:
Principal = $234 900
APR = 9 % = 0.09
Payment = $1890
Calculations:
1. Monthly interest rate
r = 0.09/12 = 0.0075
2. Interest for first month
Interest = 234 900 × 0.0075 = $1761.75
3. New Principal
Principal = $234 900.00
+ Interest = <u> + 1761.75
</u>
End of month = 236 661.75
- Payment = <u> - 1890.00
</u>
New principal = $234 771.75
The new principal is $234 771.75
Answer:
10,000
Step-by-step explanation:
The base for a normal log is 10. You raise the base by the answer, which is 4. 
is 10,000.
I am gonna use substitution method.
Solve for y in first equation,
y + 4x = 8
y = 8 -4x
Put the above y value in second equation,
5x + 2y = 13
5x + 2(8-4x) = 13
5x + 16 - 8x = 13
-3x = 13-16
-3x = -3
x = -3/-3
x = 1/1 = 1
Put the x value in first equation,
y + 4x = 8
y + 4(1) = 8
y = 8 - 4
y = 4
Hence, the solution is (1,4)
Answer:
(-1, 3)
Step-by-step explanation:
to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.
this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:
(x+4)=-5x-2
then solve for x
6x=-6
so x=-1
since we know the x value, we can solve for y
y=x+4
y=-1+4
y=3
so the final answer is (-1, 3)
