Answer: 3x-5

Step-by-step explanation:

9x-5(-6x)

9x-5-6x

3x-5

Answer:

15x - 5

Step-by-step explanation:

We have the equation 9x - 5 - (-6x) and are asked to solve it.

We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :

9x - 5 - (-6x)

Two negatives make a positive, therefore :

9x - 5 + 6x

Since 9x and 6x have the same variable ending, we can combine them, do as followed :

9x - 5 + 6x

9x + 6x

15x - 5

Answer:

The answer is B, It's the only one that doesn't equal to Zero

Step-by-step explanation:

Excluded values are also called points of discontinuity. These are the values that make the denominator equal to zero and are not part of the domain

Basically the answer cannot equal to zero.

Answer:

10/16

Step-by-step explanation:

Just multiply the denominator and the numerator by 2 and wha la you get 10/16 hope it helps!

Answer:

If you mean 5/8 ([tex]\frac{5}{8}[/tex]), then your answer would be 5 8 or 10/16 ([tex]\frac{10}{16}[/tex]).

10/16 simplified is actually 5/8!

Answer:

About 16 days.

Step-by-step explanation:

The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

Answer: 48 ft

Step-by-step explanation:

Given

Height of street light h=12 ft

length of shadow x=18 ft

Shadow length of building x'=72 ft

suppose the height of the building is y

from the figure, we can write

[tex]\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft[/tex]

Answer:

375.2887 ft is the answer

Answer:

375.3 ft

Step-by-step explanation:

What we need to do first is divide 175 by the sine of 25°.

175/sin(25°)

175/0.422618

175/1 * 500000/211309

25/1 * 500000/30187

12500000/30187

414.085534 = length of hypotenuse.

Now, find the square root of the difference between c² & a².

b = √414.09² - 175²

b = √171470.528 - 30625

b = √140845.528

b = 375.293922

b ≈ 375.3

The horizontal distance between the technician and the base of the telephone pole is 375.3 ft.

Answer:

Chemical because there is a change in color and the smoke is a change of substance.

Step-by-step explanation:

Answer:

Chemical.

Explanation:

So, before the bread was the normal color like all breads are, but then the bread was in the toaster for way to long. It started to turn black. Therefore, the change of color would be a chemical change.

Also this is the wrong subject. I'm pretty sure it's supposed to be Biology.

Answer:

7, 10

Step-by-step explanation:

X - 1 is greater than or equal to 6

+1. +1

x is greater than or equal to 7.

7 can work as

7 - 1 is greater than or equal to 6

6 is greater than or equal to 6

10 also works because if you put it in the equation the answer is still more than 6.

Step-by-step explanation:

Answer: rate of interest (r) = 6.25

Step-by-step explanation:

Simple interest formula is S.I = PxTxR/100

From the question ;

S.I = (3/8) principal

3/8p = px6xr/100

Eliminate p on both sides of the equation

r = (3x100) / (8 x 6)

r = 300 / 48

r = 6.25

Answer:

14.4 years (about 14 years 6 months)

Step-by-step explanation:

Given data

Principal= $3000

Rate= 4.8%

A. Time= 5 years

The expression for compound interest is

A=P(1+r)^t

Substitute

A= 3000(1+0.048)^5

A= 3000(1.048)^5

A=3000*1.264

A=$3792

Hence the balance will be $3792

B. Final Amount A = $6000

The expression to find time is given ast

t= ln(A/P) / r

substitute

t= ln(6000/3000)/0.048

t= ln2/0.048

t= 0.6931/0.048

t=14.43

Hence the time is 14.4 years (about 14 years 6 months)approx

Answer:

sin 33° = 0.545

Step-by-step explanation:

complementary angle to 57° is 33°

sin 33° = 0.545

Answer:

A:40%

B:7.8

Step-by-step explanation:

Using a proportion , you can solve for the bottom side.

13/19.5 = 5.2/x

multiply 19.5 and 5.2 and rewrite the equation

101.4=13x

x=7.8

To find the scale, divide 5.2 by 13

5.2/13=0.4

Double check by dividing 7.8 by 19.5

7.8/19.5=0.4

0.4=40%

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4

Answer:

y = 4

Step-by-step explanation:

Please use parentheses for clarity, remembering what big differences they make in expression values.

I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0​" actually means

2/3 - (3/2)y + (1/3)y + 4 = 0​

The LCD here is 6, which is the product of the denominators 2 and 3.

Then your "2/3 - 3/2y + 1/3y + 4 = 0​" becomes:

                     4  - 9y    + 2y + 24 = 0, which simplifies to:

                     28 - 7y = 0.  Solving this, we get y = 4
