What is the value of y in the following system?
4x - 10y = -3
12x + 5y = 12
Answers
Y=3/5
First, set it up so they cancel. I recommend multiplying the second equation by 2, getting
[tex]4x-10y=-3[/tex]
[tex]24x+10y=24[/tex]
add them together, and you get
[tex]28x=21[/tex]
so
[tex]x=3/4[/tex]
then, you plug x into one of the equations (first because it's easier) and get
[tex]3-10y=-3[/tex]
so
[tex]-10y=-6[/tex]
and
[tex]y=3/5[/tex]

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 42. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answers
Answer:
a: K = 2s
K + s = 42
b: 2s + s = 42
K = 28
s = 14
Step-by-step explanation:
1. Come up with equations based on the information given.
K = Kim
s = sister
Kim is twice of her sister -> K = 2s
When you add Kim's age to her sister's age, you get 42 -> K + s = 42
2. Substitue for K to find out the value of s
K = 2s
2s + s = 42
3. Solve for s
s = 42/3
s= 14
4. Solve for K
K = 2s
K = 2*14
K = 28

Multiply 2 and 4
x^2 - 7x - 8
(x - 8) (x + 1)
Divide by 2 for both numbers to bring the 2 back that was multiplied
(x - 4) (2x + 1)
(x - 4)
x - 4 = 0
+4 on both sides
x = 4
(2x + 1)
2x + 1 = 0
-1 on both sides
2x = -1
/2 on both sides
x = -1/2

between 9 p.m. and 6:36 a.m., the water level in a swimming pool decreased by 6/25. assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answers
Answer:
The hourly drop between the two times is 1/40
Step-by-step explanation:
Firstly, we need to find the difference in time between 9 pm and 6:36 am
That would be 9 hours and 36 minutes
It would be needed to convert 36 minutes to hours
Mathematically, 60 minutes = 1 hour
So 36 minutes = (36 * 1)/60 = 36/60 = 0.6
So the difference between the two time is simple 9.6 hours
So the total drop during the time is given by 6/25
So the hourly drop will be 6/25 divided by 9.6
= 6/25 * 1/9.6 = 6/240 = 1/40

I just need 8 and 9 pls help been stuck here forever
Answers
Answer:
8: C
9: D
10: C
11: D
Step-by-step explanation:
On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.
9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.
If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.
10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3
11 is similar, except you have 3.471 times 1/10000
So you add 4 zeros in front of the 3.471 turning it into 0.0003471

0.7(3s+4)−1.1s=7.9 I need a answer
Answers
First, expand the bracket
2.1s + 2.8 - 1.1s = 7.9
Next, collect like terms
s + 2.8 = 7.9
Lastly subtract 2.8 from 7.9 to get your answer.
s = 5.1
(Hope this helps! ^^)
Answer:
[tex]\boxed {s = 5.1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]s[/tex]:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
-Use Distributive Property:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
-Combine like terms:
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
[tex]s + 2.8 = 7.9[/tex]
-Subtract [tex]2.8[/tex] to both sides:
[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]
[tex]\boxed {s = 5.1}[/tex]
So, the value of [tex]x[/tex] is [tex]5.1[/tex].
