Answer:
34
Step-by-step explanation:
3+0.75(x-2)=0.5(x+20)
3+0.75 x-1.5=0.5 x+10
1.5+0.75x=0.5 x+10
0.75x+0.5x=10-1.5
0.25x= 8.5
0.25/25, 8.5/0.25

Evaluate 2a^2-b^3 for a = 4 and b=-3
Answer:
59
Step-by-step explanation:
2a^2 - b^3
a = 4, b = -3
substitute in the given values and solve
2*4^2 - -3^3
remember the order of operations, exponents first
2 * 4^2 - - 3^3
= 2 * 16 - - 27
simplify
2 * 16 - -27
=32 - - 27
= 32 + 27
= 59
Are the lines parallel? y = x + 4 and y = x-2
A. yes, they have the same slope and a different y-intercept
B. no, they are not parallel
Answer:
A
Step-by-step explanation:
Remember that parallel lines have the same slope.
The y-intercept does not matter.
We have the two equations:
[tex]y=x+4[/tex]
And:
[tex]y=x-2[/tex]
The slope is the coefficient in front of the x.
In the first equation, we can rewrite it as:
[tex]y=(1)x+4[/tex]
Therefore, the slope of the first equation is 1.
Similarly, for the second equation, we can rewrite it as:
[tex]y=(1)x-2[/tex]
The slope of the second equation is also 1.
Therefore, since their slopes are equivalent, they are parallel.
Thus, our correct answer is A.

Teagan believes she can use a division expression to find the amount of pizza each of 6 friends will eat if they share Four-fifths of a pizza.
Which statement best explains why Teagan is correct or incorrect?
Teagan is correct in using a division expression because Four-fifths is less than 1.
Teagan is correct in using a division expression because the question is about splitting a value into equal parts.
Teagan is incorrect in using a division expression because the term "of" in a math problem implies multiplication.
Teagan is incorrect in using a division expression because the total amount of pizza eaten is unknown.
Answer:
Option (b)
Step-by-step explanation:
It is given that,
Total no of friends are 6
The share of each friend is 4/5
Pizza eaten by each friend is equal to the total pizza eaten divided by total no of friends. It can be given by :
[tex]=\dfrac{\dfrac{4}{5}}{6}\\\\=\dfrac{4}{5}\times \dfrac{1}{6}\\\\=\dfrac{2}{15}[/tex]
It means that Teagan is correct in using a division expression because the question is about splitting a value into equal parts. Hence, the correct option is (b).

Which of the following inequalities are equivalent to the inequality x-b<3, where b is a constant? Select all that apply.
Answer:
x - b - 3 < 0
Step-by-step explanation:
o
The inequality that is equivalent to x-b < 3 will be x - b - 3 < 0. The correct option is A.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given inequality is x-b<3. Solve the inequality and match it with the options.
x - b < 3
x - b - 3 < 0
From the options, we can see that the inequality x-b<3 is equivalent to the inequality x - b - 3 < 0.
Therefore, the inequality that is equivalent to x-b < 3 will be x - b - 3 < 0. The correct option is A.

Mr. Rijo bought 49 bags of soil one week and 28 bags of soil the next week. Write an expression that correctly applies the the distributive property to show two equivalent expressions for the number of bags of soil he bought. (hint: Find GCF to help apply distributive property)
Answer:
[tex] 49 + 28 = 7(7 + 4) [/tex]
Step-by-step explanation:
Number of bags bought in one week = 49 bags
Number of bags bought the next week = 28 bags
Number of bags bought is [tex] 49 + 28 [/tex]
To express this using the distributive property, look for the greatest common factor of 49 and 28. Factor it out to get an expression.
Thus:
The factor 7 can go into 49 and 28. Factor out 7.
Therefore, we would have:
[tex] 49 + 28 = 7(7 + 4) [/tex]

A restaurant menu shows the price for 2 chicken wings is $2.30 and the price for 6 chicken wings is $6.90. The function below gives the price, y, for x wing
y - 2.30 = 1.15(x - 2)
If this function is graphed in the coordinate plane, what is the y-intercept?
Answer:
y - intercept = 0 [(0,0)]
Step-by-step explanation:
Given the equation y - 2.30 = 1.15(x-2), the y-intercept is when x is 0.
So to find your answer, just substitute in 0 for x, and solve for y:
y - 2.30 = 1.15(x - 2) →
x = 0
y - 2.30 = 1.15(0 - 2) →
y - 2.30 = 1.15(-2)
y - 2.30 = -2.30 →
+2.30 +2.30
y = 0

Shelly runs 2.5 miles in 18 minutes. what is her mile time in minutes.
Answer:
7.2315656
Step-by-step explanation:
Let's agree that 2.5 miles : 18 minutes is the ratio between the amount of distance and the amount of time spent running. If we spent 2x as many minutes running, Shelly would run 5 miles. In the same context, let's find the amount of distance covered in 18 minutes.
18 × (60/18) = 60
We multiply 60/18 because 60/18 = 60 × (1/18), and the (1/18) cancels with the 18 so we are left with the numerator, 60.
2.5 : 18
Now, we have to multiply 60/18 on both sides!
2.5 × (60/18) : 18 × (60/18) = 60
2.5 × (60/18) = 8 and 1/3 miles

Explain what is square root in simple form using example.
If something is written in its simplest radical form, that means that you have already found all possible roots and eliminated any radicals from the denominator of a fraction. ... For example, if your fraction is 2/√7, multiply by √7/√7 to get 2√7/√49. This will simplify to 2√7/7. hope this helps
Answer:
Square roots are the opposite of “squaring” a number, or multiplying it by itself. For example, three squared is nine (3 2 = 9), so the square root of nine is three. In symbols, this is √9 = 3. The “√” symbol tells you to take the square root of a number, and you can find this on most calculators.
