Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

x + 5 = -3

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -3 does indeed equal -3.

∴ x = -8 is the solution to the equation.

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Subtract 5 from both sides.

[tex]x=-3-5[/tex]

Simplify [tex]-3 -5[/tex] to [tex]-8[/tex]

[tex]x=-8[/tex]

let check if the answer is correct

[tex]x+5=-3[/tex]

Let [tex]x=-8[/tex]

[tex]-8+5=-3[/tex]

Simplify [tex]-8+5[/tex] to [tex]-3[/tex]

[tex]-3=-3[/tex]

Answer:

[tex]\$1.75[/tex]

Step-by-step explanation:

Total amount paid for the nuts is $19.60

Total amount paid for the ribbons is $11.20

Profit made on each jar is 98￠= $0.98

Cost price of the nuts and ribbon for the 40 jars is [tex]19.6+11.2=\$30.8[/tex]

Cost price for nuts and ribbonn for one jar = [tex]\dfrac{30.8}{40}=\$0.77[/tex]

Selling price is the sum of the cost price and profit.

Selling price for one jar = [tex]0.77+0.98=\$1.75[/tex]

They charged [tex]\$1.75[/tex] for each jar.

non-proportional

Step-by-step explanation:

Given equation:

[tex]y=x+3[/tex]

Create a table of ordered pairs using the given equation:

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & x+3 & y\\\cline{1-3} -3 & -3+3 & 0\\\cline{1-3} -2 & -2+3 & 1\\\cline{1-3} -1 & -1+3 & 2\\\cline{1-3} 0 & 0+3 & 3\\\cline{1-3} 1 & 1+3 & 4\\\cline{1-3} 2 & 2+3 & 5\\\cline{1-3}\end{array} \implies \begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]

Graph

As the given equation is linear, plot two of the ordered pairs and draw a straight line through them.  (See attachment).

Proportional Relationship

A relationship in which two quantities vary directly with each other.

y varies directly as x:

[tex]y=kx[/tex]

(where k is some constant)

To find if the relationship is proportional using the table, find the ratio  [tex]\dfrac{y}{x}[/tex] of each row. If the ratio is the same, the relationship is proportional.

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & y & \dfrac{y}{x}\\\cline{1-3} -3 & 0 & 0\\\cline{1-3} -2 & 1 & -0.5} \\\cline{1-3} -1 & 2 & -2 \\\cline{1-3} 0 & 3 & \text{-}\\\cline{1-3} 1 & 4 & 4\\\cline{1-3} 2 & 5 & 2.5\\\cline{1-3}\end{array}[/tex]

Graphs of proportional relationships pass through the origin (0, 0).

Therefore, the relationship is non-proportional because:

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

Step-by-step explanation:

From the question,

We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.

We substitute 5 for a and 2 for b in the given expression

2a + b - 3

= 2(5) + 2 - 3

= 10 + 2 - 3

= 12 - 3

= 9

Step-by-step explanation:

The formula for area of a rectangle is A= length times width. They gave you the area of the entire rectangle. But because this is a shape with a cutout, you still need the area of the missing section.

A= 1*4 = 4 units

Now subtract that from 49.

A=49 - 4= 45 square units

49-4 = 45

x = [tex]-\frac{75}{32}[/tex]

Step-by-step explanation:

10 = [tex]\frac{95}{2}[/tex] + [tex]4^{2}[/tex] * x

10 = [tex]\frac{5 * 19 }{2}[/tex] + ([tex]2^{2}[/tex])²x

10 = [tex]\frac{5 * 19 }{2}[/tex] + [tex]2^{2*2}[/tex] * x

x = [tex]-\frac{75}{32}[/tex]

Answer:

d=120

p=210

c=360

Step-by-step explanation:

We want to find and solve a system of equations to see how much spent each one of the 3 friends.

We can conclude that Dasher spent $120, Prancer spent $240, and Cupid spent $360.

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

To make the system of equations, first we need to define the variables that we will use.

We know that:

"Dasher spent half as much as Prancer".

"Cupid spent 3 times more than Dasher"

"In total the spent $720"

Writing the 3 equations together, we get:

To solve the system we need to replace variables, we can see that C is isolated in the second equation, then we can replace it on the last one so we get:

D = P/2

3*D + D + P = $720

Now we can replace the first one in the second one to get:

3*(P/2) + P/2 + P = $720

3*P = $720

P = $720/3 = $240

Then we can use the first equation to find the value of D:

D = P/2 = $240/2 = $120

Finally, we can use the second equation find the value of C:

C = 3*D = 3*$120 = $360

Then we can conclude that Dasher spent $120, Prancer spent $240, and Cupid spent $360.

Answer: 22.5 LBS (Or Pounds)

Work: After I multiplied 2.25 by 10, I received the answer above. Happy Holidays! :)

Answer:

22.5 pounds

Step-by-step explanation:

You multiply 10 by 2.25 to get your answer

You can just move the decimal to the right one decimal place since you're multiplying by 10

t = 12r/(r+120)

t(r+120) = 120r

tr+120t = 120r

tr-120r = -120t

r(t-120) = -120t

r = -120t/(t-120)

r = 120t/(120-t)
