7x - 4 + = 12 show me the steps

Answers

Answer 1

Answer:

impossible, but two ways:

either:

x=16/7

or:

7x+8

Step-by-step explanation:

if it is 7x-4+12, then it is 7x+8 because it is an expression.

If it is 7x-4=12, then it is x=16/7 because it is an equation.

otherwise, it is python programming or impossible.

Sierra’s ice cream shop made $45 before she had to close early when the power went out. She realized she lost Two-thirds of a dollar each hour when the shop was closed. The expression that models this situation is 45 minus two-thirds h. What was Sierra’s profit if the shop was closed for 6 hours?

Answers

Answer:

Sierra's profit was $41.

Step-by-step explanation:

Sierra realized she lost two-third of a dollar each hour when the shop was closed.

-3b - 3b= (-3b)+(-3b)= -6b

Answer:

the answer is: -6b

Step-by-step explanation:

you would subtract 3b from -3b making it -6b

Solve the equation,
9b + 15 = 4b = 10

Answers

Answer:

b=-1

Step-by-step explanation:

First step to any algebraic equation is to combine like-terms. This would mean that we would have to subtract 4b from both sides, I'm assuming its supposed to be plus ten and you just typed it wrong but, we get 5b+15=10 here we  subtract 15 from both sides and get 5b=-5. Now we isolate the variable b, getting b=-1.

Answers

Answer:

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.          

Step-by-step explanation:

We have to subtract (4x² - x + 6) from (3x² + 5x - 8).

so

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)[/tex]

Remove parentheses: [tex]\left(a\right)=a[/tex]

[tex]=3x^2+5x-8-\left(4x^2-x+6\right)[/tex]

[tex]=3x^2+5x-8-4x^2+x-6[/tex]

Group like terms

[tex]=3x^2-4x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]\:3x^2-4x^2=-x^2[/tex]

[tex]=-x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]5x+x=6x[/tex]

[tex]=-x^2+6x-8-6[/tex]

Subtract the numbers: [tex]-8-6=-14[/tex]

[tex]=-x^2+6x-14[/tex]

Therefore,

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.

In this triangle, the product of sin B and tan C is
and the product of sin Cand tan B is

Answers

Answer:

[tex]\frac{c}{a}[/tex] and [tex]\frac{b}{a}[/tex]

Step-by-step explanation:

sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{b}{a}[/tex]

tanC = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{c}{b}[/tex]

Thus

sinB tanC = [tex]\frac{b}{a}[/tex] × [tex]\frac{c}{b}[/tex] ( cancel b on numerator/ denominator )

                 = [tex]\frac{c}{a}[/tex]

---------------------------------------------------------------------------

sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{c}{a}[/tex]

tanB = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{b}{c}[/tex]

Thus

sinC tanB = [tex]\frac{c}{a}[/tex] × [tex]\frac{b}{c}[/tex] ( cancel c on numerator/ denominator )

                 = [tex]\frac{b}{a}[/tex]

Price-club sells a 12-ounce box of crackers for $2.59 and Shop Mart sells a 1-pound box of crackers for $4.68. The unit price at Price-Club is $ per ounce, and the unit price at Shop Mart is $ per ounce.

Answers

Answer:

$0.216 and $0.293

Step-by-step explanation:

Given,

Price club sells 12 ounce box = $2.59

Shop mart sells a 1 pound box = $ 4.68.

We have to find the unit price at Price club and Shop mart.

We know that 1 Pound = 16 ounce

Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]

                                      = $0.216

Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]

                                      = $0.293

It's actually [tex]1 \frac{1}{2}[/tex] pounds, not 1 pound.

Complete the equation to show how many thirds are equivalent to
8/12 = ?/3

Answers

Answer:

[tex]\frac{2}{3}[/tex]

Explanation:

What we need to do is to convert [tex]\frac{8}{12}[/tex] into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.

We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of [tex]\frac{8}{12}[/tex] - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.

So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is [tex]\frac{2}{3}[/tex].

She discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. Melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. Her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. Melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area.Based on this information, which three statements are plausible consequences of fracking in Greendale?Fracking contributed to methane finding its way into the residential water supply.Fracking is always safe to use in the proximity of Greendale's water supply.Pressure from fracking forced methane to mix with Greendale's groundwater.Fracking in Greendale produces more freshwater than it consumes.If fracking can contaminate city water, it might also poison nearby rivers.
