Super easy so what your going to do is replace x with 5 and y with 3 (it says in the directions) for example number 1 3x-2y+4 so replace the variables with numbers so when there is a number next to a letter that means to multiply so 3x5-2x3+4 then you just solve and remember pemdas and when there bit two variables next to each other multiply hope this helps

I need help with 5 1\2× 3 1\4 =?
sattari [20]

5 1/2 * 3 1/4


1 + 5 . 2/2 * 1 + 3 . 4/4 = 11/2 * 13/4 = 11 . 13/2 . 4 = 143/8 = 7 + 17 . 8/8 = 17 7/8


= 17 . 875



Detailed explanation of solution:


5 1/2 * 3 1/4


Transform the first mix number to improper fraction:


5 1/2 = 1 + 5 . 2/2 = 11/2




Transform the second mix number to improper fraction:


3 1/4 = 1 + 3. 4/4 = 13/4




Multiplying two fractions:


11/2 * 13/4 = 11 . 13/2 . 4 = 143/8




Since the numerator is greater than the denominator, We convert the improper fraction to mix fraction:


143/8 = 7 + 17.8/8


= 17 7/8 (Decimal: 17. 875)








Hope that helps!!!!!! ( Answer: 17 7/8, (Decimal: 17.875)

How can you tell how many solutions a linear equation will have by looking at the equation?
Solnce55 [7]

Answer:

A system of two equations can be classified as follows

Step-by-step explanation:

If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.

Solve the equation. Check your solution. −4x − 8x + 17 = 23
Novay_Z [31]
-4x -8x +17 = 23
-12x +17 = 23
-12x=6
x= -0.5
to check plug back in the equation

There’s a picture so I don’t have to type out the question
Lorico [155]

For this case we have the following function:

s (V) = \sqrt [3] {V}

This function describes the side length of the cube.

If Jason wants a cube with a minimum volume of 64 cubic centimeters, then we propose the following inequality:

s \geq \sqrt [3] {64}

Rewriting we have:

s \geq \sqrt [3] {4 ^ 3}\\s \geq4

Option B
