Answer:

a = -5

Step-by-step explanation:

22 = 7 -3a

(subtract 7)

15 = -3a

(divide -3)

a = -5

OR

22 = 7 -3a

(add 3a)

3a + 22 = 7

(subract 22)

3a = -15

(divide 3)

a = -5

Answer: 0.72

Step-by-step explanation:

Given:  18 out of every 25 shoppers between the age of 18 and 34 research purchases online before going to a store.

Fraction of shoppers between the age of 18 and 34 research purchases online before going to a store [tex]=\dfrac{18}{25}[/tex]

In decimal , [tex]\dfrac{18}{25}=\dfrac{18}{25}\times\dfrac{4}{4}=\dfrac{72}{100}=0.72[/tex]

Hence, this value written as a decimal = 0.72

Answer:

5:7

Step-by-step explanation:

A pet store has two types of betta fish which is red and blue

She noticed that 7 out of the 12 beta fishes are red

This means that there are 7 red beta fishes and 5 blue betta fishes

Therefore the ratio of blue betta fish to red betta fish is

= 5:7

Step-by-step explanation:

The value of all the angles in a triangle add up to 180.

So to find x do 180-(66+52)

The angle opposite of x is the same value as x

X+E or X+Z are both equal to 180.

Answer:

x = − 5, − 2

Step-by-step explanation:

x² + 7x + 10 = 0

x² + 5x + 2x + 10 = 0

x(x + 5) + 2 (x + 5) = 0

(x + 5)(x + 2) = 0

x = − 5, − 2

Answer:

A

Step-by-step explanation:

6(-3w+1/3)

-18w+2

Answer:

A

Step-by-step explanation:

6(-3w +1/3)

to distribute you multiply everything inside the parentheses by 6

so

6(-3w) + 6(1/3)

-18w + 6/3

-18w +2

Answer:

L = 3.9

Step-by-step explanation:

[tex]Area=l*l\\l^{2}=15\\[/tex]

L = 3.9

Answer:

The best estimate would have to be 3.87298334621. 3.87 if rounded to the nearest hundredth, 3.9 id rounded to the nearest tenth, and 4 if rounded to the nearest unit

Answer:

The answer is below

Step-by-step explanation:

The volume of box = width * length * height

120 = x * x * y

120 = x²y

y=120/x²

The surface area (SA) = sum of the area of all faces side

SA = x² + x² + xy + xy + xy + xy

SA = 2x² + 4xy

substitute y =120/x²

SA = 2x² + 4x(120/x²)

SA = 2x² + 480/x

Taking the derivative:

SA' = 4x - 480/x²

making SA' = 0:

0 = 4x - 480/x²

480/x² = 4x

4x³ = 480

x³ = 120

x = 4.93 feet

y = 120 / x² = 120 / 4.93² = 4.93

Hence the width, length and height is 4.93 feet.

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, 6) ← 2 points on the line

m = [tex]\frac{6-0}{0+3}[/tex] = [tex]\frac{6}{3}[/tex] = 2

Answer:

The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].

Answer: 50%

Step-by-step explanation:

Let x = Total dishes.

Dishes from China = [tex]\dfrac38x[/tex]

Dishes from Japan  = [tex]12.5\% \text{ of }x= 0.125x[/tex]

Total dishes  from China and Japan = [tex]\dfrac38 x+0.125x=0.375x+0.125x=0.5x[/tex]

Dishes from other countries [tex]= x- 0.5x= 0.5x[/tex]

Percent of dishes from other countries= [tex]\dfrac{0.5x}{x}\times100\%= 50\%[/tex]

Hence, dishes from other countries = 50%

Answer:

angle 3 im prob wrong

Step-by-step explanation:

We want to find a line that is perpendicular to y = 1/6 and that passes through (-8, -2), that line will be x = -8.

So we want to get a line, we know it must be perpendicular to y = 1/6.

Notice that y = 1/6 is a horizontal line, then our line must be vertical, this means that our line is something like x = constant.

Now if we want our line to pass through the point (-8, -2), the constant must be equal to the x-value of the point, this is:

x = constant = -8

x = -8

This is the equation of the line perpendicular to y = 1/6 and that passes through (-8, -2)

Answer:

1. 795, 23

2. 50, she will finish her candy on November 21 so she won't be able to share with her cousins

3. $276, 71 cars

Step-by-step explanation:

1. your equation: y = 35x + 235

plug in 16 to find how many pictures she will have on may 16: y = 35(16) + 235

you get y = 795

for the second part, you know are trying to find how long it will take to get to 1024 pictures, so you know your y, but you don't know your x

your equation: 1024 = 35x + 235

solve to get x = 22.54

this rounds up to 23, so your answer is 23

2. multiply 8 times 4 to get 32

subtract 32 from 82 to fin how many she has left

you get 50

for the second part, divide 82 by 4 to find how many day it will take to finish her candy

you get 20.5

so no, she will not have candy to share with her cousins, and she will finish her candy on November 21

3. for this, you have a negative y intercept since you need to make $24 to start profiting

your equation: y = 6x - 24

plug in 50 to x: y = 6(50) - 24

you get y = 276

so you make $276 with 50 cars

for the second part, plug in 400 to y: 400 = 6x - 24

solve to get x = 70.66

this rounds up to 71, so your answer is 71

Answer:

  $8.65×10^3

Step-by-step explanation:

The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.

  West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4

  = (5.38 -1.46 -2.38 -0.675)×10^4

  = 0.865×10^4 = 8.65×10^3

West raised $8.65×10^3.
