84c −4 = 72c−244 What is C?

Answers

Answer 1

Answer:

Answer:

c=20

Step-by-step explanation:

84c −4 = 72c−244

subract 72x from both sides

12c-4=-244

add 4 to both sides

12c=240

divide both sides by 12

c=20

What equals x and y?

Answers

y = -x/4 + 4
x +2y = 6

We need to solve y= -1/4 x + 4 for y
Let's start by substitute -1/4 x +4 for y in x+2y=6
x + 2y =6
x + 2(-1/4 x+4) =6
1/2 x + 8 =6
1/2 x = 6 - 8
1/2 x = -2
x = -2/1/2
x = -4
Now we need to find the value for y
Let's find it by substitute -4 for x in y= -1/4 x +4
y = -1/4 x + 4
y= -1/4 (-4) +4
y= 4/4 + 4
y = 1 + 4
y= 5

Answer : Y=5 and x= -4

I hope that's help... If you have any questions please let me know !
Good night :)

Make both equal to y and make one equatation: (6-x)/2=-x/4+4.now simply calculate that: 2-1/2x=1/4x+4
2-4=1/4x+2/4x
-2=3/4x
-2*4/3=x
-8/3=x.

Now y is (6-(-8/3))/2
(6+8/3)/2=y
1.125=y.

If this is wrong I'm sorry but I think it is right.

You are running a 10 mile race. You run the first 3 miles in 24.7 minutes. Your goal is to finish the race in less than 1 hour and 20 minutes. What should you average running time (in minutes per mile) be for the remaining miles?

Answers

Answer:

Therefore you have to run every mile in ~ 8 minutes.

Step-by-step explanation:

10 miles - 3 miles = 7 miles left.

1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes

= 55.3 minutes left

Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.

So:

7 miles = 55 minutes

1 mile x minutes

x minutes= 55 x 1 ÷ 7 miles

x minutes = 7.85

x minutes = ~ 8 minutes

Therefore you have to run every mile in ~ 8 minutes.

Hope this helps!

Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequence?A) A(n) = 2 * -6^10-1; -20,155,392
B) A(n) = -6 * 2^n; -6144
C) A(n) = -6 * 2^n-1; -3072
I need this Answered ASAP, Thank you

Answers

The general form of the geometric sequence is $a_(n) = a_(1) (r) ^(n-1)$ , where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1. Our formula then looks like this: $a_(10) =-6(2) ^(10-1)$ . Simplify it to $a_(10) =-6(2)^9$ . Take 2 to the 9th power then multiply it by -6 to get -3072. C is your answer.

Use a transformation to solve the equation. k/-4 = - 0.8

A.

k = –3.2

B.

k = –0.2

C.

k = 0.2

D.

k = 3.2

Answers

k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
   this means, (k/-4) x -4 = - 0.8 x -4
   this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
   so k= 3.2

your answer is D
