Answers
5(5a + b) - 13 is your answer
using the distributive property, we can distribute 5 to all terms within the parenthesis:
5(5a + b) - 13 = 25a + 5b - 13
5(5a) = 25a
5(b) = 5b
25a + 5b - 13 = 25a + 5b - 13 (True)

Prepare 350g of a 2% lidocaine cream using a 1% lidocaine cream a 5% lidocaine cream
Answers
5% lidocaine -y g, 0.05y pure lidocaine
(1)0.01x+0.05y=350*0.02
0.01x g we get from1% lidocoine and 0.05y g we get from 5% lidocoine
(2) x+y=350
x g is mass 1% lidocoine, we combine it with y g 5%,
so we get x+y, and we need 350g,
so x+y should be equal 350, x+y=350
we get system of 2 equations that we need to solve to find x and y
(1)0.01x+0.05y=350*0.02
(2) x+y=350
we can solve it by substitution, find x from (2) equation
x=350-y, substitute it into (1)
instead of x we put (350-y)
0.01(350-y)+0.05y=7
3.5-0.01y+0.05y=7
0.04y =3.5
y=87.5g 5% lidocaine
b)x=350-87.5=262.5 g 1% lidocaine
c) 350g =350000 mg
Define x and y:
------------------------------------------------------------------
Let x be the amount of 1% lidocaine needed.
Let y be the amount of 5% lidocaine needed.
------------------------------------------------------------------
Construct Equations:
------------------------------------------------------------------
x + y = 350
0.01x + 0.05y = 0.02 x 350
0.01x + 0.05y = 7
------------------------------------------------------------------
Solve x and y:
------------------------------------------------------------------
x + y = 350 ------------- (Equation 1)
0.01x + 0.05y = 7 ------------- (Equation 2)
------------------------------------------------------------------
From equation 1:
------------------------------------------------------------------
x + y = 350
x = 350 - y
------------------------------------------------------------------
Substitute x = 350 - y into equation 2:
------------------------------------------------------------------
0.01(350 - y) + 0.05y = 7
3.5 - 0.01y + 0.05y = 7
3.5 + 0.04y = 7
0.04y = 7 - 3.5
0.04y = 3.5
y = 87.5
------------------------------------------------------------------
Substitute y = 87.5 into equation 1:
------------------------------------------------------------------
x + y = 350
x + 87.5 = 350
x = 350 - 87.5
x = 262.5
------------------------------------------------------------------
Find x and y:
------------------------------------------------------------------
x = 262.6g (5% lidocaine cream)
y = 87.5g (1% lidocaine cream)
------------------------------------------------------------------
Convert 350g to milligram:
------------------------------------------------------------------
350g = 350 x 1000 mg
350g = 350 000mg
------------------------------------------------------------------
Answer:
(a) Amount of 5% lidocaine needed = 87.5g
(b) Amount of 1% lidocaine needed = 262.g
(c) 350g = 350 000mg

For her cell phone plan Heather pays $30 per month plus 0.05 protects she wants to keep her bill under $60 per month with any quality represents the number of texts T Heather can't spend each month while staying within her budget
Answers
Let the number of texts be represented by T.
The we get the following function of total cost:
Total cost = 30 + 0.05T.
Since Heather wants her bill to be under $60, the total cost must be smaller than 60. We get the following
30 + 0.05T < 60
Subtract 30 from both sides.
0.05T < 30
Divide by 0.05
T < 600. Therefore Heather can send a maximum of 600 texts (and then she pays a bill of $60)

The ratio of the length to the width to the height of a rectangular box of cereal is 6:2:7. The sum of the length and the width of the box is 24 centimeters. Find the surface area of the box of cereal
Answers
18 cm : 6 cm : 21 cm
The surface area (S) is given in terms of length (L), width (W), and height (H) by
S = 2(LW +H(L+W))
= 2((18 cm)*(6 cm) +(21 cm)*(18 cm +6 cm))
= 2(108 cm² +(21 cm)*(24 cm))
= 1224 cm²
The surface area of the box of cereal is 1224 cm².
Using an algebraic rule, describe a translation 2 units to the left.
Answers
point (x,y) translated 2 units to the left will give the point (x-2,y)
(x,y) = (x-2,y)
Explanation:
We will apply the translation on a given point.
Suppose that we have a point with coordinates (x,y).
We want to translate this point 2 units to the left. This means that we will move this point 2 units to the left.
Doing this, we will find that:
the x-value of the coordinate is decreased by 2
the y-value of the coordinate did not change as no translation occurred in the vertical axis.
Therefore:
a point (x,y) can be translated two units to the left to be (x-2 , y)
Hope this helps :)

We are done.
Consider the difference of polynomials [tex](7x^8 + 8x^6 - 2x + 9) - (4x^8 + 3x^7 + 3).[/tex]
The first thing you have to do is take that "minus" sign through the parentheses containing the second polynomial (just change sign + to - and sign - to +):
[tex](7x^8 + 8x^6 - 2x + 9) - (4x^8 + 3x^7 + 3)=7x^8+8x^6-2x+9-4x^8-3x^7-3.[/tex]
Then combine terms with the same degree:
[tex]7x^8+8x^6-2x+9-4x^8-3x^7-3=(7x^8-4x^8)-3x^7+8x^6-2x+(9-3).[/tex]
Note that
[tex]7x^8-4x^8=(7-4)x^8=3x^8,\\ \\9-3=6.[/tex]
Thus,
[tex](7x^8 + 8x^6 - 2x + 9) - (4x^8 + 3x^7 + 3)=3x^8-3x^7+8x^6-2x+6.[/tex]

the width of a rectangle is X and the length is twice he width. if the area of the rectangle is 162, what is X?
Answers
To find the value of X in a rectangle with width X and length 2X, we can use the area formula. By solving the equation, we find X = 9, making the width of the rectangle 9 units.
Explanation:To find the value of X, we need to use the given information about the length and width of the rectangle. Let's assume the width of the rectangle is X. Since the length is double the width, it is 2X. The area of the rectangle is given as 162, so we can set up the equation:
Width × Length = Area
X × 2X = 162
Simplifying the equation, we get:
2X^2 = 162
Dividing both sides by 2, we have:
X^2 = 81
Taking the square root of both sides, we find:
X = ±9
Since the width cannot be negative, the value of X is 9. Therefore, the width of the rectangle is 9 units.
