Answer:
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60

Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Algebra I
Combining Like TermsStep-by-step explanation:
Step 1: Define Equation
4x + 5 = 13x + 4 - x - 9
Step 2: Solve for x
Combine like terms: 4x + 5 = 12x - 5Subtract 4x on both sides: 5 = 8x - 5Isolate x term: 10 = 8xIsolate x: 5/4 = xRewrite: x = 5/4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(5/4) + 5 = 13(5/4) + 4 - 5/4 - 9Multiply: 5 + 5 = 65/4 + 4 - 5/4 - 9Add: 10 = 81/4 - 5/4 - 9Subtract: 10 = 19 - 9Subtract: 10 = 10Here we see that 10 does indeed equal 10.
∴ x = 5/4 is the solution to the equation.
10/3 = x divided by -5/2
x = ?
Answer:
-4/3
have a nice day/night
Answer:
x = -25/3
Step-by-step explanation:
x divided by -5/2 is equal to x multiplied by -2/5
therefore, proportion is [tex]\frac{10}{3}[/tex] = [tex]\frac{-2x}{5}[/tex]
cross-multiply: -6x = 50
x = -50/6 or -25/3
if p(X)=x²-4x+5, then the value of p(1) is____
a)-1. b)0 c)1 d)2
Answer:
[tex]p(x)=x^{2}-4x+5\\p(x)= 1^{2}-4(1)+5\\p(x)=1-4+5\\p(x)=2[/tex]
So 2 is the answer.

Step-by-step explanation:
You go to Wal-Mart to buy some holiday candy. You decide to buy snickers because they have a special deal on snickers. A bag
of snickers costs $3.45, but if you buy 4 or more bags, they only cost $3.00 per bag.
Create a piecewise function to represent the cost of the bags of snickers.
6
SNICKERS
Let "n" be the number of bags of snickers
and "C(n)" be the cost of all bags of snickers purchased.
The piecewise function is
C(n) - {(first option)
{ (second option)
Answer:
The piecewise function is given as follows;
[tex]\begin{cases}C(n) = \$ 3.45 \times n & \text{ if } x< 4 \\ C(n) = \$ 3.00 \times n & \text{ if } x\geq 4 \end{cases}[/tex]
Step-by-step explanation:
The given parameters are;
The cost of each bag of snickers = $3.45
The cost of each bag of sneakers when buying 4 or more bags = $3.00
Let "n" be the number of bags of snickers and "C(n)" be the cost of all the snickers purchased
The piecewise function is C(n) = {($3.45 × n) for n < 3
{($3.00 × n) for n ≥ 4
A plane traveled 322 miles from El Paso in a direction 57° northeast. What is height of the plane, to the nearest mile?
Answer:
The height of the plane to the nearest mile is 175 miles
Step-by-step explanation:
Here, we want to calculate the direction of the plane
A diagrammatic representation of this will be interesting
Please check an attachment for this
From the diagram, consider the triangle OAB
we want to calculate the height of this triangle
We simply apply trigonometric identity
Thus, we have that;
Sine 33 = h/322
h = 322 sine 33
h = 175.37
h is approximately 175 miles

Step-by-step explanation:
180-130=50
50/2=25
Answer:
x = 25 degrees
Step-by-step explanation:
the figure is an isosceles triangle
x + x + 130 = 180
2x + 130 = 180
2x = 180 - 130
2x = 50
x = 25 degrees
7÷7/11=
Please explain for me
Answer:
11
Step-by-step explanation:
You have to first make the 7 into a fraction (7/1) then keep, change, flip.
You keep the 7/1 as it is, you change the division sign into a multiplication sign, and you flip the 7/11 to 11/7. You then just multiply straight across to get 77/7 which is the same thing as 11/1 which is the same thing as 11!
