18(x + 1) = -54 pls help solve this...​

Answers

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

Answers

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

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]

What is the slope of the line.

Answers

-4/5 is the skip of the graph

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.

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.

Answers

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
