determine the simple interest when:
principal is $890, interest rate is 4.25% and the time is over 2 years
Answer:
$75.65
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 890 × 0.0425 × 2 = 75.65
I = $ 75.65
The simple interest accumulated
on a principal of $ 890.00
at a rate of 4.25% per year
for 2 years is $ 75.65.
The figures are similar. Find x.

eight less than the product of a number n and 1/5 is no more than 98
Answer:
8<n+1/5<98
Step-by-step explanation:
Simplify: 16 - [11 - {8+ (17 +3x2 - 19)}]
The given expression
= 16 - [11 - {8+ (17 + 3 x 2 - 19)}]
= 16 - [11 - {8+ (17 + 6-19)
= 16 - [11 - {8+ 4)] = 16 -- [11 -2]
= 16 - 9 = 7.

Robert is serving 16 drinks to his friends. Three times as many friends are drinking lemonade as tea, and 4 are drinking water. How many of each type of drink does Robert serve?
Answer:
9 lemonade, 3 tea, 4 water
Answer: Robert should serve 3 for tea, 9 for lemonade, and 4 for water.
Step-by-step explanation:
Since you don't know how many friends are drinking lemonade or tea, you should give them variables.
x = amount of friends drinking tea
3x = amount of friends drinking lemonade
We already know how many are drinking water, so there's no need for a variable.
Then, make an equation:
x + 3x + 4 = 16
Simplify:
4x + 4 = 16
Isolate the variable by subtracting 4 from both sides:
4x = 12
Isolate the variable by dividing both sides by 4:
x = 3, so 3 friends are drinking tea
3x = 9, so 9 friends are drinking lemonade
Double check the work by replacing the variables with their actual numbers:
3 + 9 + 4 = 16
Simplify:
16 = 16
Therefore, the answer is correct.

7 4 9 as an improper fraction
2x plus 3 plus x2; for x = 4
Answer:
2x+3+x2 if x=4 is 27
Step-by-step explanation:
2*x or 2*4=8
8+3=11;
and x or 4 times itself is 16
so we add it all together and get 27.
Have a great day!
Answer:
27
Step-by-step explanation:
Not sure if you mean x to the power of 2, so I'll assume that.
Replacing the variable for 4 should look like:
2(4) + 3 + 4^2
8 + 3 + 16 (4 to the power of 2 is equivalent to 4 x 4 which is 16)
Now add them all, 27.
Jesse went to the store with a total of $45. He bought a
hat that cost $12, a hat for $10 and some ties. If each
tie cost $4. What is the most amount of ties he can buy?
asap pls
Answer: He can buy 5 ties
Step-by-step explanation:
12+10=22. 4x5=20. 22+20=42. If you add 1 more tie, you will have $46, so you cannot add one more tie. So the most amount of ties he can buy is 5 ties, with $3 left to spare.

What is 3(2x +7x - 5 )
Answer:
x = 15/27
Step-by-step explanation:
3(2x + 7x - 5)
Distribute the 3
6x + 21x - 15
Combine like terms
27x - 15 = 0
27x = 15
x = 15/27
Answer:
27x - 15 is your expression
Step-by-step explanation:
3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

The ratio of dogs and cats in the veterinarians office is 9:7What is the ratio of dogs to the number of dogs and cats in the veterinarians office
Answer:
9:16
Step-by-step explanation:
If there are 9 dogs and 7 cats and you need to know the total number of cats and dogs add the numbers together (16) and put the number of dogs in front of it (9). So the answer is 9:16
Answer:
9:16
Step-by-step explanation:
because he ratio of cats to dogs is 9:7, so that means the 9 is how many dogs their are, 9 + 7= 16, making 9:16 (i'm wrong i'm positive i might be right)
6X + 8Y - 4Z = 5

Por favor cómo se resuelve esta matriz por método Gauss-Jordan
Responder:
la solución (x, y, z) es (4.48, 4.86, -1.04)
Explicación paso a paso:
Dadas las ecuaciones simultáneas;
6X + 8Y - 4Z = 5 .... 1
1X + 2Y + 5Z = 9 ... 2
9X - 3Y + 3Z = 6 .... 3
Primero necesitamos reducir el sistema de ecuaciones
Ecuación 1 * 1
Ecuación 2 * 4
__________
6X + 8Y - 4Z = 5
4X + 8Y + 20Z = 36
Restar
6x-4x - 4z-20z = 5-36
2x-24z = 31 ... 4
también
ecuación 2 * 3
ecuación 3 * 2
_______________
1X + 2Y + 5Z = 9 * 3
9X - 3Y + 3Z = 6 * 2
_______________
3x + 6y + 15z = 27
18x - 6 años + 6z = 12
Agregar
3x + 18x + 15z + 6z = 27 + 12
21x + 21z = 39 ...... 5
Resolviendo 4 y 5
2x-24z = 31 ... 4 * 21
21x + 21z = 39 ...... 5 * 2
____________
42x - 504z = 651
42x + 42z = 78
Sustraer
-504x - 42z = 651-78
-546z = 573
z = -573/546
z = -1.05
Sustituye z = -1.05 en 4
De 4;
2x-21z = 31
2x - 21 (-1,05) = 31
2x + 22,04 = 31
2x = 31-22.04
2x = 8,96
x = 8,96 / 2
x = 4,48
Obtener y
De 2:
X + 2Y + 5Z = 9
4.48 + 2y + 5 (-1.04) = 9
2 años + 4,48-5,2 = 9
2y = 9 + 0,72
2 años = 9,72
y = 9,72 / 2
y = 4,86
Por tanto, la solución (x, y, z) es (4.48, 4.86, -1.04)
