Given A and B


What is X if B - X= A?


(Solving Matrix Equation)

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: 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:

The temperature will drop 24 degrees

Step-by-step explanation:

-3 degrees/hour for 8 hours

-3 x 8 = -24

It is negative.

Answer:

In 8 hours time it will be drop 24 degrees

8x3 = 24

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

Answer:

Than just stay on brainly. lol

Step 1: Find the slope

Point 1 = (0, -4)

Point 2 = (-7, -10)

m = (-10 - - 4) / (-7 - 0) = (-10 + 4) / (-7 - 0) = -6 / -7 = 6/7

m = 6/7

Step 2: Find the y-intercept

Slope-Intercept Form: y = mx + b

-m is the slope

-b is the y-intercept

---Plug in any of the given points as well as the slope into slope-intercept form and solve for b

Point: (-7, -10)

-10 = (6/7)(-7) + b

-10 = -6 + b

b = -4

Step 3: Form the equation

Slope-Intercept Form: y = mx + b

m = 6/7

b = -4

y = 6/7x - 4

Hope this helps!! :)

Answer:

y = 3x/4 + 3

Step-by-step explanation:

y = mx + b

b = 3

(-4,0), (0,3)

m = 3/4

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:1.2

Step-by-step explanation:

Answer:

5/6 or 0.83

Step-by-step explanation:

there's 5 piece but 6 people. everyone would get less then an equal piece.

5÷6= 0.833333 or in fraction 5/6.

if you divide 6 people and 5 pieces you get 1.2 size piece. that's more then the cake has, which is 5 pieces. That's what I think.

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:

x=-2.01970690

Step-by-step explanation:

Yes it is a factor

Answer:

Yes, x+2 is a factor of f(x)

Step-by-step explanation:

-2 | 1   -3   -3    9   -4    12

   ___-2_ 10_-14_10  -12

     1   -5    7    -5   6  | 0

Since [tex]\frac{x^5-3x^4-3x^3+9x^2-4x+12}{x+2}=x^4-5x^3+7x^2-5x+6[/tex] with no remainder, then x+2 is a factor

Answer:

a) 100m

b) 2m/s

Step-by-step explanation:

a)==>> 2+4+6+8+10(8) = 100m

b)==>> Variable "a" = change OVER time ([tex]\frac{change}{time}[/tex]) = 8m/4s = 2m/s

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]
