6. Talayah bought two journals. The second
journal cost $12 more than the price of
the first journal. If she spent $30 on both,
how much was the second journal?
A. $12
B. $16
C. $20
D. $28
Answer:
C. $20
Step-by-step explanation:
Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30
Subtract 12 from each side: x + 4/5x = 18
Combine like terms : 1 4/5 x = 18
Divide each side by 1 4/5 : x = 10
Plug in x for the journals-
1 = 10
2 = 4/5 of 10 = 8 + 12 = $20

A recipe used 1/2 cup of sour cream for every 1/4 teaspoon of salt. What is the unit rate of teaspoons of salt per cup of sour cream?
Answer:
1/2 teaspoons of salt per cup of sour cream
Step-by-step explanation:
multiply 1/2 and 1/4 by 2 to get 1 and 1/2. Since the question is teaspoons of salt per cup of sour cream, flip the numbers to get 1/2 teaspoons of salt per 1 cup of sour cream.
what is the absolute value of │38│
Answer:
38
Step-by-step explanation:
if there are bars around it its automatically positive even if it was -38 the absolute would still be 38.
Answer: 38
Step-by-step explanation: The absolute value of a number
is that number's distance from zero on a number line.
Since 38 is 38 units from zero, the absolute value of 38 is just 38.

Kim has $250 to spend on a rental car for her trip. The rental car company charges a fee of $130 plus $0.10 per mile. Kim used the inequality to calculate the maximum number of miles, m, she could drive the rental car.
Which inequality expresses the maximum number of miles Kim can drive the car?
m < 3,800
m < 120
m < 380
m < 1,200
Answer:
m < 1,200
Step-by-step explanation:
250 - 130 = 120
120 / 0.10 = 1,200

If the solution to an equation is x = −5, what could the original equation be?
A. x + 3 = 8
B. x − 3 = 8
C. x + 8 = 3
C. x − 8 = 3
(sorry if this is easy for you, I'm bad at math.)
Answer:
The answer is c definitely
Answer:
C. x + 8 = 3
Step-by-step explanation:
x + 8 = 3
x + 8 - 8 = 3 - 8 ( so do the same thing you do on both the left and right side )
x = -5
So C is correct but you can always say 3 - 8 to figure out that the answer in c is the right one.

Find the slope of the line perpendicular to 2x+3y=8
Answer:
Marissa.
Step-by-step explanation:
To find perpendicular slope you basically take the slope of the given line and reverse whatever sign it had previously. (If it was negative, it would become positive. If it was positive it would become negative.)
By doing -A/B it make the previous slope negative.
Brandon only flipped the fraction which would just result in the slope being slightly steeper, or in this case, less steep than the previous line, rather than making it perpendicular.
Hope this helps! Stay safe and if you have any questions feel free to ask!

2. Addison bought 9 pumpkin pies for $27. How much will she pay for 11 pumpkin pies? Use numbers and words to explain your answer.
Answer:
$33
Step-by-step explanation:
Since 9 pies is 27 dollars that means you have to divide 27 by 9 to find out what 1 pie costs
1 pie ends cause costing $3
now you multiply the cost for 1 pie and 11 so it comes out to be $33

30. The table below shows the average temperature of a lake in months since April in a certain year. Find
the equation for the curve of best fit using a quadratic model, then predict the average temperature of
the lake during December of the same year. Round all answers to the nearest hundredth.
Month
Temp (°F)
April
59
May
68
June
71
July
78
August
74
1
Answer:
The temperature, in December is 47 °F
Step-by-step explanation:
The given data for the temperature are;
Month [tex]{}[/tex] Temp (°F)
April [tex]{}[/tex] 59
May [tex]{}[/tex] 68
June [tex]{}[/tex] 71
July [tex]{}[/tex] 78
August [tex]{}[/tex] 74
Let x represent the month, and f(x) = y represent the temperature, we have;
y = a·x² + b·x + c
When x = 1, we have, f(1) = a·1² + b·1 + c = 59
f(1) = a + b + c = 59...(1)
When x = 2, we have, f(2) = a·2² + b·2 + c = 68
f(2) = 4·a + 2·b + c = 68...(2)
When x = 3, we have, f(3) = a·3² + b·3 + c = 71
f(3) = 9·a + 3·b + c = 71...(3)
When x = 4, we have, f(4) = a·4² + b·4 + c = 78
f(3) = 16·a + 4·b + c = 78...(4)
When x = 5, we have, f(5) = a·5² + b·5 + c = 74
f(3) = 25·a + 5·b + c = 74...(5)
Subtracting equation (3) from equation (5), we get;
25·a + 5·b + c - (9·a + 3·b + c) = 74 - 71
16·a + 2·b = 3...(6)
Subtracting equation (1) from equation (2), we get;
4·a + 2·b + c - (a + b + c) = 68 - 59
3·a + b = 9...(7)
Multiply equation (7) by 2 and substract from equation (6) gives;
16·a + 2·b - 2 × (3·a + b) = 3 - 2 × 9
16·a + 2·b - 6·a - 2·b = 3 - 2 × 9
16·a - 6·a + 2·b - 2·b = 3 - 2 × 9 = -15
10·a = -15
a = -15/10 = -1.5
a = -1.5
From, 3·a + b = 9, we have;
3 × (-1.5) + b = 9
b = 9 + 4.5 =13.5
b = 13.5
From, a + b + c = 59, we have;
-1.5 + 13.5 + c = 59
c = 59 - (-1.5 + 13.5) = 47
c = 47
The quadratic equation becomes, y = a·x² + b·x + c = -1.5·x² + 13.5·x + 47
f(x) = y = -1.5·x² + 13.5·x + 47
For December, we have, x = 9, and f(x) = -1.5×9² + 13.5×9 + 47 = 47
The temperature, in December = 47 °F
Section 1 - Question 1 Consider these six expressions.

A 2 B 3 C 4 D 5 q-q help me this is confusing
Answer:
B 3
Step-by-step explanation:
Given
[tex]Expression\ A: (-5)(-0.4)(1.8)[/tex]
[tex]Expression\ B: (-45)(-19)(-112)[/tex]
[tex]Expression\ C: -1(5+17)[/tex]
[tex]Expression\ D: (-5)(-0.4)(1.8)(-3.25)[/tex]
[tex]Expression\ E: (-49)(-34)(-12)(-12)[/tex]
[tex]Expression\ F: -1(3.5-7)[/tex]
Required
How many of them will have a positive result
Taking the expressions one after the other:
[tex]Expression\ A: (-5)(-0.4)(1.8)[/tex]
Convert brackets to multiplication
[tex]Expression\ A: -5*-0.4*1.8[/tex]
[tex]Expression\ A: 3.6[/tex]
This has a positive product
[tex]Expression\ B: (-45)(-19)(-112)[/tex]
Convert brackets to multiplication
[tex]Expression\ B: -45*-19*-112[/tex]
[tex]Expression\ B: -95760[/tex]
This has a negative product
[tex]Expression\ C: -1(5+17)[/tex]
Solve the expression in bracket
[tex]Expression\ C: -1 *22[/tex]
[tex]Expression\ C: -22[/tex]
This has a negative product
[tex]Expression\ D: (-5)(-0.4)(1.8)(-3.25)[/tex]
Convert brackets to multiplication
[tex]Expression\ D: -5*-0.4*1.8*-3.25[/tex]
[tex]Expression\ D: -11.7[/tex]
This has a negative product
[tex]Expression\ E: (-49)(-34)(-12)(-12)[/tex]
Convert brackets to multiplication
[tex]Expression\ E: -49*-34*-12*-12[/tex]
[tex]Expression\ E: 239904[/tex]
This has a positive product
[tex]Expression\ F: -1(3.5-7)[/tex]
Solve the expression in bracket
[tex]Expression\ F: -1*-3.5[/tex]
[tex]Expression\ F: 3.5[/tex]
This has a positive product
Expressions A, E and F have positive products. This implies that, there are 3 expressions with a positive product.
Find the area of the shaded region. Express your answer in terms of π.
Answer:
335.115
Step-by-step explanation:
First you find the area of the circles to do that you do pi times radius squared
For the top square do 3.14(pi)time 3²=28.26
For the middle square do 3.14 times 4.5²=63.585
For the bottom square do 3.14 times 6²=113.04
Now find the area of the entire thing do 18×12+9+6+3=18×30=540
Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115
So the shaded region is 335.115
Hope this helps and have a great day!
which number is bigger 1.59 or 1.955
Answer:
1.955 is bigger
Step-by-step explanation:
1.955>1.59
Answer:

Sarah uses long division to convert a rational number x/y to its decimal form. Which of the following statement cannot be true?
y - 3 = -2 ( x + 5 ) in standard form
Answer:
2x + y = -7
Step-by-step explanation:
Standard form is Ax + By = C
A represents the coefficient with x
B represents the coefficient with y
C represents the constants
1 - Rewrite to make it easier to work it out
y - 3 = -2 ( x + 5 )
2 - Distribute
y - 3 = -2x - 10
3 - Get the variables on one side and the constants on the other
y - 3 = -2x - 10
+ 2x + 2x
2x + y - 3 = -10
+ 3 + 3
2x + y = -7
Hope this helps,
