Solve the equation log.(13-x)= 1.

Mathematics

1 answer:

Ivahew [28]3 years ago

Answer:

Step-by-step explanation:

13 - x = 1

So isolate x

You need to subtract 13 from both sides to isolate x.

13 - x = 1

13 - 13 -x = 1 - 13

13 -13 equals 0 so it cancels out.

You are left with

- x = 1 -13

-x = -12

Divide the negatives on both sides.

Since a negative divided by a negative equals a positive...

x = 12!

The ratio of mikes savings to nicks savings was 4:3 after mike saved another $120 and nick saved another $60 the ratio became 8:

DIA [1.3K]

Answer:

Mike's savings before he saved additional money = $120

Nick's savings before he saved additional money = $90

Step-by-step explanation:

The ratio of mikes savings to nicks savings was 4:3.

Let their savings be 4k and 3k.

After mike saved another $120 and nick saved another $60, their savings become 4K+120 and 3k+60.

It is given that the new ratio is 8:5.

Therefore,

4k+120 : 3k+60 = 8:5

$\frac{4k+120}{3k+60} =\frac{8}{5}$

5(4k+120) = 8(3k+60)

20k+600 = 24k+480

20k-24k = 480-600

-4k = -120

k = 30

So, Mike's savings before he saved additional money = 4k = 4(30) = $120

Nick's savings before he saved additional money = 3k = 3(30) = $90

Write an equation in slope-intercept form for the line that satisfies the following condition.

mihalych1998 [28]

Answer:

y=8/3x-34/3

Step-by-step explanation: If the line is parallel to y=8/3x+7, then the slope must be 8/3. So, we can eliminate A and B. Now, let's take C, and plug in (8, 10) into the equation. We end up with 10=64/3-34/3. 64-34=30. 30/3=10. 10 = 10. So, C is the correct answer. No need to check for D.
