Answer:
4 months and 13 stamps
Step-by-step explanation:
Use a char, add two stamps each month for Joy and subtract 3 for Ronald.
blank 2: 13 stamps
explanation : for Joy add 2 stamps each month ( 2 times 4 equals 8 stamps) add 8 stamps to original 5 stamps ( 8+5=13)
for Ronald subtract 3 stamps each month (3 times 4 equals 12 stamps) subtract 12 stamps from original 25 stamps ( 25-12=13)
both end up with 13 stamps left over a time period of 4 months.

75 – 3.5y – 4y = 4y + 6
Answers
Answer:
y=6
Step-by-step explanation:
75-3.5y-4y=4y+6
combine like terms)
75+(-3.5y-4y)=4y+6
75-7.5y=4y+6
add 4y to each side to combine the terms) 75+(-7.5y-4y)=6
75-11.5y=6
subtract 75 from each side to isolate the variable) -11.5y=-69
divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5
y=6
Rearrange to make x the subject: 3x+8= has x+6y
Answers
Answer:
x=3y-4
Step-by-step explanation:
3x+8=x+6y
so the goal here is to make everything equal to x. first, let's move all the X's to one side by subtracting x on both sides.
2x+8=6y
now we want x alone on one side so we subtract 8 on both sides.
2x=6y-8
divide by 2
x=3y-4
Answer:
x = 3y - 4
Step-by-step explanation:
Given
3x + 8 = x + 6y ( subtract x from both sides )
2x + 8 = 6y ( subtract 8 from both sides )
2x = 6y - 8 ( divide all terms by 2 )
x = 3y - 4
The local high school sold 1914 tickets this year to its spring musical. That was 174 more tickets sold than last year. What is the percent increase in the number of tickets sold?
Answers
Answer:
.909 (ROUNDED)
Step-by-step explanation:
In order to do this all you need to do is divide the number with the number you got this year, 1914, and with the number last year.
1914-174=1740
1740 was the amount they got last year
Now you want to find the percent difference between the two.
1740/1914=.909090 (Repeats)
So the percent increase would be
.909090
.101010
20 POINTS An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. The total cost of the electrician's services can be determined using the equation C=65+60t, where t is the number of hours the electrician spends at the house working. What is the slope of the equation and what is its interpretation in the context of the problem?
Answers
Answer:
[tex]the \: slope \: is \to \boxed{60}[/tex]
Step-by-step explanation:
[tex]if \to C=65+60t \\ C=60t + 65 \\ but \: the \: \boxed{ c - intercept} \: is \: in \: the \: form \to \\ c = mt + b \\ hence \to \\ 60t = mt \\ m = \frac{60t}{t} \\ m = 60 \\ the \: slope \: is \to \boxed{60}[/tex]
We want to analyze the given linear equation, we will find that the slope is 60, and it means that he charges 60 per hour.
Linear equations:
A general linear equation is written as:
y = a*x +b
Where a is the slope and b is the y-intercept.
In this case, we have the equation:
c(t) = 60*t + 65
Is easy to identify that the slope is equal to 60.
Given that we know that he charges per hour, and that t represents the number of hours that the electrician worked, we can assume that the slope represents how much the electrician charges per hour.

(3x-4)(x+7)-1/4x^2 as a trinomial in standard form. If you can pls provided step by step explanation
Answers
The trinomial in standard form is 11/4x² + 17x - 28
How to rewrite the expression?The expression is given as:
(3x-4)(x+7)-1/4x^2
Rewrite properly as:
(3x - 4)(x + 7) - 1/4x²
Expand the expression
3x² - 4x + 21x - 28 - 1/4x²
Collect like terms
- 1/4x² + 3x² - 4x + 21x - 28

Use the remainder theorem to determine the remainder. Then use the remainder to determine if the binomial is the factor of a polynomial. f(x) = x^3 + x^2 - 66x + 54 is divided by x + 9.
a. Remainder: 0; not a factor
b. Remainder: 0; yes a factor
c. Remainder: 270; not a factor
d. Reaminder:270; yes a factor
Answers
Answer:
b
Step-by-step explanation:
f(x) = x³ + x² - 66x + 54
= (x² - 8x + 6)(x + 9) + 0
=> the answer is b
Answer:
b
Step-by-step explanation:
If (x + h) is a divisor of f(x) then f(- h) = remainder
If f(- h) = 0 then (x + h) is a factor of f(x)
Here divisor is (x + 9) , then
f(- 9) = (- 9)³ + (- 9)² - 66(- 9) + 54
= - 729 + 81 + 594 + 54
= 0
Thus remainder is 0 and (x + 9) is a factor of f(x)

A) He used 1 cup of sugar for every 1 3/4 pies he made
B) He would use 14 cups of sugar to make 8 pies
C) The number of cups of sugar is proportional to the number of pies he made because he used the same number of cups of sugar for each pie
D) The number of cups of sugar is not porptional to the number of pies he made because the increase in the number of cups of sugar between Monday and Tuesday is greater than the increase in the number of pies
E) if Nathan uses 8 3/4 cups of sugar to make 5 pies on Wednesday and then graphs the points, for all the three days, to represent the relationship between the cups of sugar used and the number of pies made, the points would not fall on a straight line
