Answer: 265.9167 square inches (rounded)

Step-by-step explanation:

Shoot, okay if this is wrong, shame on me:

All you do is find the areas of each rectangle and add them together.

(12 × 13 1/3) + (10 1/4 x 10 1/3) = 265.9167 (rounded) square inches. Or as a fraction: 3191/12

Answer:

3000+60+42

Step-by-step explanation:

the order of operations says to multiply and divide from left to right before adding or subtracting from left to right. Putting the numbers in parenthesis helps.

(500*6)+(10*6)+(7*6)

(3000)+(60)+(42)

3000+60+42

Hope this helps!

Answer:

y = -0.5x - 7 or y = -1/2x - 7 (both are same)

Step-by-step explanation:

m = slope

slope = y2 - y1 / x2 - x1

-9 - (-8) / 4 - 2 = -1/2 = -0.5

m = -0.5 

b = y-intercept

b = -7

y = mx + b

y = -0.5x + (-7)

y = -0.5x - 7

(negative slope)

Answer:

Graph D (last graph)

Step-by-step explanation:

y + 2 > 5

first subtract 2 from both sides

y > 3

Now that we know the solution to y we can plot it. We know it must start at 3, but also not be included because our solution is not ≥. This means we have an open box at 3 and an arrow in the positive direction.

Answer:

2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)

Step-by-step explanation:

y − x = 9

y = x + 9

x+9 = x²+3x-7

x²+2x-16=0

x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17

x = 3.12 or x = -5.12

y = 12.12 or y = -3.87

Answer:

12

Step-by-step explanation:

7 (number of tickets) times 12 (cost of ticket) = 84     169 (total spent) - 84 (total ticket price) = 85   85 divided by 7 (price of popcorn) = 12.14 round down as they wouldn't have enough money to buy more than 12 popcorns.

Answer:

[tex]7\frac{1}{4}[/tex]

Step-by-step explanation:

Change to improper fraction.

[tex]8\frac{1}{2}[/tex] ⇒ [tex]\frac{17}{2}[/tex]

[tex]1\frac{1}{4}[/tex] ⇒ [tex]\frac{5}{4}[/tex]

Find the least common denominator (LCD) of the two fractions. ⇒ 4

[tex]\frac{34}{4}[/tex] - [tex]\frac{5}{4}[/tex] = [tex]\frac{29}{4}[/tex]

Convert to a mixed number.

[tex]\frac{29}{4}[/tex] ⇒ [tex]7\frac{1}{4}[/tex]

Hence, [tex]8\frac{1}{2} - 1\frac{1}{4} = 7\frac{1}{4}[/tex]

Answer:

Answer:

x = -3

a) 6 ft

b) 7 ft

c) 9 ft

d) 11 ft

e) 5 ft

f) 14 ft

Step-by-step explanation:

set up the equation

-2x + 4 - x +x +12 + 3x + 20 + 2x + 11 + 7x + 35 = 52

combine like terms

10x + 82 = 52

single out the variable

10x = -30

x = -3

substitute x in all the following equations

a)  -2(-3) = 6

b)  4 - -3 = 7

c)  -3 + 12 = 9

d)  3(-3) + 20 = 11

e)  2(-3) + 11 = 5

f)  7(-3) + 35 = 14

Step-by-step explanation:

You can use multiplication along with converting statements to symbols.

The equation for the given condition is given by [tex]y = 42x[/tex]

where y represents the total number of letters Natasha puts in envelops in x hours.

You need to know how to convert the statement to symbolic expression.

Suppose if it is said that a thing is increased by 4,then we write it as

that thing + 4

Suppose if it is written that 'x' objects are sold on p price per object. Since 1 object is sold at p price, then x objects will be sold at:

[tex]p + p + ... + p \: \: \: (x \: \: times) = p \times x[/tex]

Such conversion can help us to form symbolic expressions from the given description.

Since for the given case, in 1 hour, Natasha put 42 letters in envelopes, then in x hour she will put:

[tex]42 + 42 + ... + 42 \: \: (x \: times) = 42 \times x[/tex]

Since in x hours, she puts y envelopes but envelopes put in x hours came out as 42 times x, thus, both the values are equal, or

[tex]y = 42 \times x = 42x \text{\:\:(written in short)}[/tex]

The equation for the given condition is given by [tex]y = 42x[/tex]

where y represents the total number of letters Natasha puts in envelops in x hours.
