Step-by-step explanation:
Answer:
i =−4
Step-by-step explanation:
1=2i+9
Step 1: Flip the equation.
2i+9=1
Step 2: Subtract 9 from both sides.
2i+9−9=1−9
2i=−8
Step 3: Divide both sides by 2.

Miss McKee has 1,183 gold stickers. She wants to give the same number of stickers to each of her 30 students. If she gives away as many stickers as she can, how many stickers will be left over?
Answer:
If she gives away as many stickers as she can, stickers left = 13
Step-by-step explanation:
Total number of gold stickers = 1183
Total number of students = 30
So, each student will get = [tex]\frac{1183}{30}[/tex] = 39.433
As the gold stickers cannot be given in integer form
So , each student get 39 stickers.
So, 30 students get = 30×39 = 1170
So Left over stickers = 1183 - 1170 = 13

Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep. She wants to fill the box with other packages that
are 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
What is the greatest number of packages that she can put in the box without it overflowing?
Answer:
50 packages
Step-by-step explanation:
Area of the box: A= (l)(w)(h)
=(20)(5)(10)
=1000cm^3
Area of the package: A= (5)(1)(4)
=20cm^3
1000/20=50 packages
50 number of packages that she can put in the box without it overflowing
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep.
Length=20
Width=5
Height=10
Area of cube=Length×width×height
=20×5×10
=1000 cm³
The other packages is 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
Area=5×1×4
=20 cm³
We need to find the greatest number of packages that she can put in the box without it overflowing
To find this we have to divide 1000 by 20
1000/20=50
Hence, 50 number of packages that she can put in the box without it overflowing

Ashley spent $35 on her meal at Longhorn Steakhouse and leaves a $6.30 tip. What percent tip did Ashley leave?
Answer:
18%
Step-by-step explanation:
Given that,
Ashley spent $35 on her meal at Longhorn Steakhouse and leaves a $6.30 tip.
We need to find what percent tip did Ashley leave. The percentage of tip leaved by Ashley is given by :
[tex]\%=\dfrac{6.3}{35}\times100\\\\\%=18\%[/tex]
So, 18% of tip is leaved by Ashley.
Emily hires someone to walk her dog during the day. The cost for 2 walks
is $9.00.
What is the cost for 5 walks?
Answer:
2 walks is $9.00 so first i would find the unit rate
Step-by-step explanation: To find the unit rate you would have to get 2 to 1 which means we would have to divide it by 2. 2 / 1 is 1 then we also have to divide 9 by 2 which would get you 4.5. Now you know that 1 walk is $4.50 , but you need to know how much it coust for 5 so you multiply by 5. $4.50 x 5 = $22.50

foot. The sales tax was 8%. If Krista paid with a $100.00 bill, how much
change should she have received? *
Answer:
$24.40
Step-by-step explanation:
take 35*2 to get the total (70)
take 8% (for the sales tax) or 0.08 times $70 to get 5.6
take 5.6 plus 70 = 75.60
take 100 minus 75.60 = $24.40

Consider the system of linear equations 2x + 3y = 8 and 3x + y = –2. Which statement is correct?
The point (1, 2) is not a solution to the system of equations because it satisfies neither equation.
The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
The point (1, 2) is a solution to the system of equations because it satisfies the equation 2x + 3y = 8.
The point (1, 2) is a solution to the system of equations because it satisfies both equations.
Answer:
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Step-by-step explanation:
System of Equations
Consider the following system of equations
2x + 3y = 8 [1]
3x + y = -2 [2]
And the point (1,2). Substituting in both equations:
For equation [1]:
2*1 + 3*2 = 8
2 + 6 = 8
8 = 8
Since the equation is true, point (1,2) satisfies the equation 2x + 3y = 8
Now for equation [2]:
3*1 + 2 = -2
3 + 2 = -2
5 = -2
Since this equation is false, point (1,2) does not satisfy the equation 3x + y = -2
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Answer:
B: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.

Woodhill Elementary School is planning a field trip for grades 3, 4, and 5.
There is a total of 464 students. There are only 45 seats per bus. How
many buses will be needed for the field trip?
Answer:
11 buses
Step-by-step explanation:
If you divide 464 by 45, you will get 10.3. You need to round this number up to 11, since you would need another bus to carry the 0.3 of students left over.

a line includes the points 2, 10 and 0, 2 what is its equation in slope intercept form
Answer:
y = -4x + 2
Step-by-step explanation:
y = mx + b ( slope-intercept)
1. Find Slope:
[tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]
Lets name 2 as y2 and 10 as y1. And 0 as x2 and 2 as x1.
[tex]\frac{2-10}{0-2}[/tex] = [tex]\frac{-8}{2}[/tex] = -4
m/slope = -4
2. Find y-intercept:
[tex]y = mx +b[/tex]
2 = -4(0) + b
= 2 = b
Y-intercept/b = 2
3. Put into slope-intercept form:
y = mx + b
= y = -4x + 2
