Malik used these steps to solve the system of equations. 2 x 4 y = 20. 5 x minus 3 y = 11. Step 1 6 x 12 y = 60. 20 x minus 12 y = 44. Step 2 Step 3 x = 4 Step 4 2 (4) 4 y = 20. 8 4 y = 20. 4 y = 12. Y = 3. Step 5 The solution is (4, 3). What needs to be done in step 2? Divide both sides of the equations in step 1 by the same number to eliminate one variable. Multiply both sides of the equations in step 1 by the same number to eliminate one variable. Add the equations in step 1 to eliminate one variable. Subtract the equations in step 1 to eliminate one variable.
The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
Given to us
2x + 4y = 205x - 3y = 11Step 1: Multiply the first equation with 3, while the second equation with 4,
6x + 12 y = 60
20x - 12 y = 44
Step 2: Add both the equations,
(6x + 12y) + (20x - 12y) = 60+44
Step 3: caluculate the value of x,
x = 4
Step 4: Substitute the value of x in equation 1,
2(4) + 4y = 20
8 + 4y = 20.
4y = 12
Y = 3
Step 5: The solution is (4, 3).
Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.

Step-by-step explanation:
A store is having a 20% off sale. The sale price of an item with price p is p – 0. 2p. What is an equivalent expression? p.
After the store gives 20% off sale, the expression of the item at price p can be written as, p-0.2=0.8p.
Given to us
A store is having a 20% off sale.
The sale price of an item with price p is p – 0. 2p.
What is the total price of the item?We know that for any item the price can be 100%(1.00) of itself, therefore, the price of the item will be p.
What is the expression is equivalent to?We know that for any item the price can be 100%(1), therefore, after giving 20%(0.2) off sale, the price will be 80%(1-0.2 = 0.8) of the original.
Thus, the expression is equivalent to
[tex](100\%)p-(20\%)p = 80\%p\\\\1p-0.2p = 0.8p\\\\p-0.2p=0.8p[/tex]
Hence, after the store gives 20% off sale, the expression of the item at price p can be written as, p-0.2=0.8p.

Find the volume of the composed figure.
Answer:
96 ft³
Step-by-step explanation:
The front face can be considered as a 5×10 rectangle with a 3×6 rectangle cut from it. Then its area is ...
A = (5×10) -(3×6) = 32 . . . square feet
The volume of a prism of uniform cross section is ...
V = Bh . . . . . where B is the area of the base, and h is the height
Our figure has a base area of 32 square feet and a height of 3 feet, so its volume is ...
V = (32 ft²)(3 ft) = 96 ft³

~[tex]\frak{Amphitrite1040:)}[/tex]The percentage of increase from 75 to 110 is approximately 46.7%.
The correct option is 46.7%.
To calculate the percent of increase from 75 to 110, we can use the following formula:
Percent Increase = (New Value - Old Value) / Old Value * 100
Substituting the values, we have:
Percent Increase = (110 - 75) / 75 * 100
Calculating the numerator and denominator separately:
Numerator = 110 - 75 = 35
Denominator = 75
Substituting these values into the formula:
Percent Increase = (35 / 75) x 100 ≈ 46.7%
Therefore, the percentage of increase from 75 to 110 is approximately 46.7%.
It's important to note that the percent of the increase represents the relative change in value from the old value to the new value, expressed as a percentage of the old value. In this case, the value has increased by approximately 46.7% from 75 to 110.

Jerome's average balance checking account pays simple interest of 7. 2% annually, and he made $5. 28 in interest last month. What was Jerome's average balance last month?.
Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period.
The balance of the last month of Jerome's account is $880
What is simple interest?
Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.
The formula for the simple interest can be given as,
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Here, [tex]I[/tex] is the interest rate on the principal amount of [tex]P[/tex] with the rate of [tex]r[/tex] in the time period of [tex]t[/tex].
Given information-
Jerome's average balance checking account pays simple interest of 7.2% annually.
Jerome made $5.28 in interest last month.
Convert the interest rate monthly as,
[tex]r=\dfrac{7.2}{12} \\r=0.6[/tex]
Thus the monthly interest rate is 0.6 percent.
Suppose the balance of the last month is [tex]P[/tex]. Use the above formula to find the principal amount,
[tex]I=\dfrac{P\times r\times t}{100}\\5.28=\dfrac{P\times 0.6\times 1}{100}[/tex]
Solve it for [tex]P[/tex],
[tex]P=\dfrac{5.28\times100}{0.6\times1} \\P=\dfrac{528}{0.6} \\P=880[/tex]
Hence, The balance of the last month of Jerome's account is $880.
