Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
[tex]log_{x}[/tex] 5 + [tex]log_{x}[/tex] 12 = 7 , then
[tex]log_{x}[/tex] (5 × 12) = 7 , that is
[tex]log_{x}[/tex] 60 = 7 , thus
[tex]x^{7}[/tex] = 60 → B

8x + 7y = 39
4x – 14y = –68
make sure to give a long paragraph for edginuity
Answers
Answer:
Step-by-step explanation:
Using the linear combination method, you can multiply the first equation by 2 and add the equations to get 20x = 10. Dividing both sides by 20, x = 1/2. To solve for y, substitute 1/2 for x in the equation 8x + 7y = 39 to get 4 + 7y = 39. Solving this equation, y = 5. Checking this in the other equation, 4(1/2) – 14(5) = –68 results in 2 – 70 = –68 or –68 = –68. The solution of the system shown is (1/2, 5). The system 8x + 7y = 39 and 20x = 10 is formed by replacing 4x –14y = –68 by a sum of it and a multiple of 8x + 7y = 39. Since 20(1/2) = 10, the system 8x + 7y = 39 and 20x = 10 also has a solution of (1/2, 5)

-(3x+y=32)

3x+(5)=32
-5. -5
3x=27
x=9
Answer:
x=9
y=5
Answer:
x = 9
y = 5
Step-by-step explanation:
3x + y = 32...(1)
3x - 2y = 17....(2)
multiplying equation (1) by 2 we get,
6x + 2y = 64...(3)
Adding eq(2) and (3) we get,
6x + 2y = 64
+ 3x - 2y = 17
----------------------
9x. = 81
therefore, x = 81/9
therefore, x = 9
substituting value of x in eq( 1)
3 * 9 + y = 32
27 + y = 32
y = 32 - 27
y = 5

Hence, value of y = 5.5.
Answer: y = 5 ½ or y = 5.5
Step-by-step explanation:
4y - 7 = 15
Add 7 to both sides of the equation.
4y = 22
Divide both sides by 4
y = 5.5
Substitute y in the original equation.
4(5.5) - 7 = 15
22 -7 = 15

Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest.
Answers
Answer:
You would receive $510.08 in return.
Step-by-step explanation:
In order to find the answer, you can use the formula to calculate the future value:
FV=PV*(1+i)^n
FV=future value
PV= present value= 500
i= interest rate=0.03/12=0.0025 per month
n= number of periods of time= 8
Now, you can replace the values in the formula:
FV=500*(1+0.0025)^8
FV=500*(1.0025)^8
FV=510.08
According to this, the answer is that you would receive $510.08 in return.

Six friends share 3/4 of a pound of roasted almonds. What fraction of a pound does each friend receive
Answers
Answer: 1/8 pounds of roasted almonds
Step-by-step explanation:
There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.
The almonds each friend will get will therefore be the 3/4 pack divided by 6:
= 3/4 ÷ 6
= 3/4 * 1/6
= 3/24
= 1/8 pounds of roasted almonds
When dividing by a number, you can instead multiply by the inverse of that number.
Un jugador de basquetbol ha realizado los 2/5 del número de puntos conseguidos por su equipo en un partido y otro la tercera parte del resto. Si los demás jugadores han conseguido 34 puntos, ¿cuántos puntos obtuvo el equipo en el partido?
Answers
Answer:
85 points
Step-by-step explanation:
Let :
Total points made by team = x
Points made by the player :
2/5 of total = 2x/5
1/3 of the rest :
Points left = x - 2x/5= 3x /5
1/3 of 3x /5
1/3 * 3x / 5
= 3x / 15 = x / 5
Points made by rest of the players = 34 points
Hence, total points scored, x :
x = 34 + 2x /5 + x /5
x = 34 + 3x / 5
x - 3x/5 = 34
2x / 5 = 34
2x = 34 * 5
2x = 170
x = 170 / 2
x = 85
Total points scored by team = 85
