I’m confused on this pls help me

Answer:

-4 - (1-3) - (-4)² =

- 4 - (-2) - 16

-4 + 2 - 16 = -18

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

[tex]\\ \sf\longmapsto Perimeter=4a[/tex]

[tex]\\ \sf\longmapsto Perimeter=4(2x+2)[/tex]

[tex]\\ \sf\longmapsto Perimeter=8x+8[/tex]

Step-by-step explanation:

solution,

Length=2x+2

Perimeter of a square=4l

=4(2x+2)

=8x+8

Answer:

p=-30

Step-by-step explanation:

p+12=-18

subtract 12 on both sides and you get p=-30

Hope this helps!!

in order for the product to be less then 5/8, it would have to be multiplied by a fraction that is less then 1.

so ur answer would be : 7/10 x 5/8

Hi there!

I believe your answer is:  

[tex]\frac{x}{2} =50\\\\x = 100[/tex]

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{Setting up an Equation...}}}\\\\\text{Half a number...}} \rightarrow\frac{x}{2} \\\\\text{...gives 50.} \rightarrow = 50\\\\\text{Half a number gives 50 should be: } \frac{x}{2} = 50[/tex]

⸻⸻⸻⸻

[tex]\boxed{\text{Solving for 'x'...}}\\\\\frac{x}{2} = 50\\-------------\\\\\rightarrow( \frac{x}{2})2=50*2\\\\\rightarrow \boxed{x = 100}}[/tex]

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.  

Answer:

[tex]take \: the \: number = x \\ then \: x \div 2 = 50 \\ x = 50 \times 2 = 100 \\ thank \: you[/tex]

Answer:

i think she should draw 3

B,C,D

Step-by-step explanation:

Answer:

eda periodt

Step-by-step explanation:

If h(x) is the inverse of f(x), then by definition of inverse function, we have

f(h(x)) = x

By definition of f(x), composing f with h gives

f(h(x)) = 2 h(x) - 10

Solve for h(x) :

x = 2 h(x) - 10

2 h(x) = x + 10

h(x) = (x + 10)/2

h(x) = x/2 + 5

So... whichever option most closely resembles this is the correct one. It's hard to tell exactly which one that would be.

Answer:

Step-by-step explanation:

The proportion of the length of the smaller rectangle to the bigger rectangle must be 2 : 5 as well.

Hence x : 11 = 2 : 5.

Or x = (2/5) x 11 = 22/5.

Answer:

the second option 2a-6b+c

Answer:

2a - 6b + c

Step-by-step explanation:

(a+a)(-5b-b)(2c-c)

2a-6b+c

Answer:

304

Step-by-step explanation:

8 x 13 = 104

+200

304

Answer:

96feet

Step-by-step explanation:

U want to find displacement

So

Displacement = velocity x time

Velocity = - 8 feet/s ( negative bcuz going down)

Time = 13

Displacement = - 8 x 13

= - 104

Therefore

200 - 104 = 96feet

Answer:

$2624

Step-by-step explanation:

8x235=1880

2x372=744

1880+744=2624=$2624

Step-by-step explanation:

it is easy and I think i explain it in better way.

Answer:

y=2

Step-by-step explanation:

2y + 8y - 20 = 5 (y -2)

Combine like terms

10y -20 = 5(y-2)

Divide by 5

10y/5 -20/5 = 5/5(y-2)

2y -4 = y-2

Subtract y from each side

2y-y -4 =-2

y -4 = -2

Add 2 to each side

y-4+4 =-2+4

y =2

Answer:

[tex]2y + 8y - 20 = 5(y - 2) \\ 10y - 20 = 5y - 10 \\ 5y = 10 \\ y = 2 \\ thank \: you[/tex]

Answer:

0

Step-by-step explanation:

Answer:

Step-by-step explanation:

Length = 5 * 3 = 15 feet

Width = 3.5 * 3 = 10.5

Area: 15 * 10.5 = 157.5 square feet

c=number of crossings; Q=quarterly pass; S=semi-annual pass; P=pay as you go

P=$2.50c

Q=$12+$0.50c

S=$40

Compare single pay and quarterly ticket:

$2.50c=$12+$0.50c Subtract $0.50c from each side

$2.00c=$12 Divide each side by $2.

c=6 6 crossings is the break even for single pay and quarterly ticket: more crossings favor the ticket.

Compare quarterly and semi-annual tickets:

3 month pro-rated cost of semi annual ticket=$20

$20=$12+$0.50c Subtract 12 from each side

$8=$0.50c Divide each side by $0.50

16=c The break=even point between quarterly and semi annual tickets is 16 crossings per 3 months. More than this favors the semi annual ticket.

ANSWER: The three month pass is the best deal if you cross between 6 and 16 times during the three month period.

I hope this help you

{X ∈ √144ƒ+25+5/12ƒ , √144ƒ+25+5/12ƒ }

Answer:

y = 1

z = 1

Step-by-step explanation:

y = 5y = 5

5y = 5

y = 5/5 = 1

z = 3z = 3

3z = 3

z = 3/3 = 1

Answer:

The fourth answer option is correct

Step-by-step explanation:

x - 5y = 6......transpose -5y to the other side and change the negative sign to positive

x = 5y + 6
