A package of bacon holds 15 strips of bacon. The pancake house uses 17 packages of bacon in the morning and 21 packages in the afternoon. How many more strips were used in the afternoon than the morning?
Answer:
60 more strips were used in the afternoon
Step-by-step explanation:
Bacon used in the morning
17 packages * 15 strips/ package = 255 strips
Bacon used in the afternoon
21 packages * 15 strips/package = 315
Difference = 315-255 =60
60 more were used in the afternoon
Solve 7x − 6 > 8 and 3x + 4 ≥ 22 for x.
Answer:
x ≥ 6
Step-by-step explanation:
Lets solve the first inequality:
7x - 6 > 8
7x > 8 + 6
7x > 14
x > 14/7
x > 2
And now the second inequality:
3x + 4 ≥ 22
3x ≥ 22 - 4
3x ≥ 18
x ≥ 18/3
x ≥ 6
So, from the 2 answers, which region is overlapping ?? x ≥ 6
So this is the solution.
Note: we disregard x from 2 to 6 because that region is ONLY solution to the first one

Step-by-step explanation:
solve -3(-8b+7)=3(2b-1)
Answer: [tex]b=1[/tex]
Step-by-step explanation:
Given the equation [tex]-3(-8b+7)=3(2b-1)[/tex] you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:
[tex]-3(-8b+7)=3(2b-1)\\\\24b-21=6b-3[/tex]
Now you need to add 21 to both sides of the equation:
[tex]24b-21+21=6b-3+21\\\\24b=6b+18[/tex]
Subtract [tex]6b[/tex] from both sides:
[tex]24b-6b=6b+18-6b\\\\18b=18[/tex]
And finally, you can divide both sides of the equation by 18:
[tex]\frac{18b}{18}=\frac{18}{18}\\\\b=1[/tex]
Answer:
b=1
Step-by-step explanation:
You first need to multiply -3 and -8b. That will be 24b. Then you multiply -3 times 7. That will be -21. On the other side, you will multiply 3 times 2b which will equal 6b. Then you multiply 3 by -1. You will get -3. So at this point, the equation should look like this, 24b-21=6b-3. Then add 21 to both sides. You will have this equation, 24b=6b+18. Then subtract 6b from both sides, 18b=18. Finally, divide 18 from both sides to get your final answer of b=1.

Hence
[tex]\sqrt[3]{857375}[/tex] = [tex]\sqrt[3]{95^{3} }[/tex] = 95
which equation represents the line that is parallel to 3x-4y=7
Answer:
Option B (3x - 4y = -4).
Step-by-step explanation:
Parallel lines are the straight lines that never meet. This is only possible when the gradients of both the lines are same. This means that the slopes of all the parallel lines in a group can be calculated by calculating the slope of one of the lines. Therefore, the slope of the line that is parallel to the line 3x-4y=7 is the same as the original line. Hence, the gradient can be extracted from the original line by converting the equation in the form y=mx+c, where m is the slope.
3x - 7 = 4y.
y = (3/4)x - 7/4.
The slope of the line which has to be found is 3/4 and it passes through (x0, y0) = (-4, -2). Using the following formula:
(y - y0) = m*(x - x0).
(y + 2) = (3/4)*(x + 4)
Cross multiplying:
4y + 8 = 3x + 12.
3x - 4y = -4.
Hence, Option B is the correct choice!!!

Which function is increasing and has a constant slope?
Answer:
We need to find the increasing function with constant slope.
Let us check each option one by one.
A) 6x -5y =10.
Let us solve it for y to get slope-intercept form
6x-5y =10.
-5y =-6x +10.
y =6/5 x-2.
Slope is 6/5 positive, therefore, it's an increasing function.
A linear function always has a constant slope.
Therefore, correct option is option A.
A. 6x -5y =10
All other options are incorrect.
Step-by-step explanation:
Please mark brainliest and have a great day!

(APEX ANSWER) (you can answer anyways to rack up points but i mostly posted bc i dident see it when i looked for it)
Answer:
18
Step-by-step explanation:
thanks..
..
Answer:
C. 18
Step-by-step explanation:
Let x represent number of stereos.
We have been given that a salesman sold each stereo for $1500. He earned a commission of 16.5% on each stereo sold.
The amount of commission earned on each stereo would be 16.5% of 1500.
[tex]1500\times \frac{16.5}{100}=15\times 16.5=247.5[/tex]
The amount of commission earned on x stereos would be [tex]247.5x[/tex].
We are told his base salary is $33,170, so total salary of salesman would be [tex]247.5x+33,170[/tex].
We are also given that last year he earned $37,625. We can represent this information in an equation as:
[tex]247.5x+33,170=37,625[/tex]
[tex]247.5x+33,170-33,170=37,625-33,170[/tex]
[tex]247.5x=4455[/tex]
[tex]\frac{247.5x}{247.5}=\frac{4455}{247.5}[/tex]
[tex]x=18[/tex]
Therefore, the salesman sold 18 stereos last year.
Yvette earns a $45,000 salary plus a 12% commission on any sales over $10,000. Last year Yvette made $30,000 in sales. How much did Yvette earn in salary plus commission ?
She earns commission on the amount of sales over $10,000
Subtract 10,000 from her sales to get the amount she earns commission on:
30,000 - 10,000 = 20,000.
multiply that by the percent:
20,000 x 0.12 = 2400
She earned $2,400 in commission.
Now add that to her salary to find her total pay:
45,000 + 2,400 = $47,400
Answer:
$47,400.
Step-by-step explanation:
We have been given that Yvette earns 12% commission on any sales over $10,000. Last year Yvette made $30,000 in sales.
The amount on which Yvette will get commission would be [tex]\$30,000-\$10,000=\$20,000[/tex].
Since Yvette gets 12% commission, so amount earned as commission would be 12% of $20,000.
[tex]\text{Commission}=\$20,000\times \frac{12}{100}[/tex]
[tex]\text{Commission}=\$20,000\times 0.12[/tex]
[tex]\text{Commission}=\$2,400[/tex]
Yvette also gets a salary of $45,000, so Yvette's total earnings would be $45,000 plus $2,400.
[tex]\text{Yvette's total earnings}=\$45,000+\$2,400[/tex]
[tex]\text{Yvette's total earnings}=\$47,400[/tex]
Therefore, Yvette's earned $47,400 in salary plus commission.
Simplify into one fraction 3/x-3 - 5/x-2
Answer:
[tex] \frac{3}{x - 3} - \frac{5}{x - 2} = \frac{3(x - 2) - 5(x - 3)}{(x - 3)(x - 2)} = \frac{3x - 6 - 5x + 15}{(x - 3)(x - 2)} = \frac{9 - 2x}{(x - 3)(x - 2)} [/tex]
To simplify the expression 3/x-3 - 5/x-2 into one fraction, you need to find a common denominator. The simplified expression is (-2x+9) / [(x-3)(x-2)].
Explanation:To simplify the expression 3/x-3 - 5/x-2 into one fraction, we need to find a common denominator.
The denominator of the first fraction is x-3 and the denominator of the second fraction is x-2.
The common denominator will be (x-3)(x-2) since that is the product of the two denominators.
Multiplying the numerator and denominator of the first fraction by (x-2) and the numerator and denominator of the second fraction by (x-3), we get:
[(3)(x-2)] / [(x-3)(x-2)] - [(5)(x-3)] / [(x-3)(x-2)]
= (3x-6) / [(x-3)(x-2)] - (5x-15) / [(x-3)(x-2)]
Now that we have a common denominator, we can combine the terms in the numerator:
(3x-6 - 5x+15) / [(x-3)(x-2)] = (-2x+9) / [(x-3)(x-2)]
Therefore, the simplified expression is (-2x+9) / [(x-3)(x-2)].
