Answer:
8 - 4 x = -(2 x - 17)
Step-by-step explanation:
Solve for x:
-4 (x - 2) = -2 (x - 17/2)
Hint: | Put the fractions in x - 17/2 over a common denominator.
Put each term in x - 17/2 over the common denominator 2: x - 17/2 = (2 x)/2 - 17/2:
-4 (x - 2) = -2(2 x)/2 - 17/2
Hint: | Combine (2 x)/2 - 17/2 into a single fraction.
(2 x)/2 - 17/2 = (2 x - 17)/2:
-4 (x - 2) = -21/2 (2 x - 17)
Hint: | In (-2 (2 x - 17))/2, divide -2 in the numerator by 2 in the denominator.
(-2)/2 = (2 (-1))/2 = -1:
-4 (x - 2) = -1 (2 x - 17)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
Answer: 8 - 4 x = -(2 x - 17)

Krista bought 35 feet of ribbon at the store. The ribbon cost $2 per linear
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
y = -2x +7
y = 5-7
Find the solution to the system of equations
y = 5 - 7
=> y = -2 -------(i)
y = -2x + 7
=> -2 = -2x + 7 [From (i)]
=> -2 -7 = -2x
=> -9 = -2x
=> -9/-2 = x
=> 9/2 = x
So, x = 9/2 and y = -2

George has just purchased a small rectangular fish tank that holds 837 milliliters of water. The tank has a width of 6.2 cm and a
height of 9 cm.
What is the length of the fish tank?
Answer:
Step-by-step explanation:
Answer:
15 cm
Step-by-step explanation:
Area = Length ⋅ Width ⋅ Height
let's set:
Area: 837
Length: X
Width: 6.2 cm
Height: 9cm
837 = X ⋅ 6.2 ⋅ 9
First multiply 6.2 and 9 to get 55.8
Next divide 837 by 55.8 and you get 15
therefore, the length (x) is equal to 15
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.

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
