Answer:
j/2+3
Step-by-step explanation:
Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.
Then it says that George is 3 years older, so that would be addition.
Therefore, it would be:
x/2+3

18(x + 1) = -54 pls help solve this...
Answer:
x = 71
Step-by-step explanation:
18(x + 1) = -54
to start off, subtract 18 from both sides
18 - 18(x + 1) = -54 - 18
that should give you
x + 1 = 72
(its safe to take out paranthesis from problem by now) now take away 1 from each side
x + (1 - 1) = 72 - 1
that should give you
x = 71
A caterer charges $275 for 15 people and $425 for 25 people. The cost, y, is a
linear function of the number of people. Write an equation in slope-intercept
form for this situation.
Answer:
y = 15x + 50
Step-by-step explanation:
We set out by finding the slope
the two points give are (15,275) and (25,425)
Slope m is;
y2-y1/x2-x1 = (425-275)/25-15 = 150/10 = 15
So the equation is like;
y = 15x + b
To get b, let us use the point (15,275)
We have
275 = 15(15) + b
b = 275-225
b = 50
So the equation is;
y = 15x + 50

Student council is selling Roses and Candy Grams for Valentine's Day. Each Candy Gram costs $1.50
and each Rose costs $2.00. The student council made $368 from their sales. They sold a total of 217
Roses and Candy Grams. How many roses were sold? Show all your work for full marks! (Solve the linear
system using substitution or elimination).
Letr represent
Let c represent
I
Answer:
Number of Roses sold = 132
Number of Candy Grams sold = 85
Step-by-step explanation:
Let the number of Roses sold = [tex]r[/tex]
Let the number of Candy Grams sold = [tex]c[/tex]
Cost of one Rose = $1.50
Cost of [tex]x[/tex] Roses = $1.50 [tex]r[/tex]
Cost of one Candy Gram = $2.00
Cost of [tex]y[/tex] Candy Grams = [tex]\$2.00 \times c[/tex]
Total number of Roses and Candy Grams sold = 217
i.e.
[tex]r+c=217 ..... (1)[/tex]
Total cost = $368
Writing equation as per question statement:
[tex]\$1.50r+\$2.00c=\$368 ..... (2)[/tex]
Using elimination method, let us eliminate [tex]y[/tex] of the two equations.
Multiplying equation (1) with 2 and subtracting equation (2) from it:
[tex]0.50r=2\times 217 - 368\\\Rightarrow 0.50r=434 - 368\\\Rightarrow 0.50r=66\\\Rightarrow r=132[/tex]
By equation (1):
[tex]c=217-132\\c=85[/tex]
So, the answer is:
Number of Roses sold = 132
Number of Candy Grams sold = 85

What is the slope of the line.
Answer:
-4/5
Step-by-step explanation:
The slope of the graph is -4/5. The slope is the change in y over the change in x. The y-value decreases by 4 and the x-value increases by 5. So the slope is -4/5. One visual way to check this is to remember that slopes that are fractions will make the line flatter, while numbers with absolute values greater than 1 make the slope steeper.
Each set of ordered pairs represents a function. Write a rule that represents the function (0, 0), (1, 1), (2, 4), (3, 9), (4, 16)

125 = 5³, and the given expression reduces to
[tex]\left(\sqrt{125}\right)^{\frac13}\cdot\left(\sqrt[3]{125}\right)^{\frac12}=\left(125^{\frac12}\right)^{\frac13}\cdot\left(125^{\frac13}\right)^{\frac12}=125^{\frac16}\cdot125^{\frac16}=125^{\frac13}[/tex]
so it has a value of 5.
Now:
• the first choice is equivalent, since 625 = 25², so
[tex]\dfrac{\sqrt[3]{625}}{5^{\frac13}}=\dfrac{25^{\frac23}}{5^{\frac13}}=\dfrac{5^{\frac43}}{5^{\frac13}}=5[/tex]
• the second choice is not equivalent, since
[tex]5 \cdot 25^{\frac13} = 5 \cdot 5^{\frac23} = 5^{\frac43}[/tex]
• the third choice is also equivalent, since
[tex]\dfrac{\left(\sqrt[4]{5}\right)^7}{125^{\frac14}}=\dfrac{5^{\frac74}}{5^{\frac34}}=5[/tex]
• the fourth choice is also equivalent, since
[tex]\dfrac{5^{\frac12}\cdot25^{\frac13}}{\sqrt[6]{5}}=\dfrac{5^{\frac12}\cdot5^{\frac23}}{5^{\frac16}}=\dfrac{5^{\frac76}}{5^{\frac16}}=5[/tex]
Five more than a number is 25. What is this number?
Answer:
5
Step-by-step explanation:
let the number be a.
5a=25
divide both sides by 5
5a=25
5divide by 5a is a.
5divided by 25 is 5
therefore,a=5.
the number is 5

Tracy is saving to buy a new guitar that costs $253.77 (including tax). Tracy has saved $136.27, and she can save $23.50 each week.
Which equation could you use to find how long it will take to save for the guitar?
$253.77 + $136.27 = $23.50 w
$253.77 - w = $136.27 + $23.50
$136.27 + $23.50 w = $253.77
$23.50 w = $253.77

complete the statements below about the graphs of y=-2x and y=x
Answer:
Compared to the graph of y = x, the graph of y = -2x is steeper.
Compared to the graph of y = x, the graph of y = -2x intersects the y-axis at the same point.
Compared to the graph of y = x, the graph of y = x + ⅔ is equally steep.
Compared to the graph of y = x, the graph of y = x + ⅔ intersects the y-axis at a higher point.
