What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are Given that Amelia purchased a new mattress when it was on sale. The sale price was 30% less than the regular price. If the sale price was $353.
Therefore, 100% - 30% = 70%
$353 represents 70% of the original cost.

Is 1 + 4(3x - 10) - 12x equivalent to -9? EXPLAIN and show your work.
Answer:
Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:
1 + 12x - 40 -12x
= 1 - 40
= -39
Step-by-step explanation:
Answer: No
Step-by-step explanation:
1 + 4(3x - 10) - 12x = 9
simplifies to
1+12x - 40 -12x =9

Step-by-step explanation:
Prove that the triangle with vertices A(0,1), B(3,3), and C(3,-1) is an isosceles triangle. Select the two sides that are congruent.
Answer:
AB and AC are congruent
Step-by-step explanation:
To show that the triangle is isosceles, we need to show that two of the sides of the triangle are equal.
Get AB
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
A(0,1), B(3,3)
AB = √(3-0)²+(3-1)²
AB = √3²+2²
AB = √9+4
AB = √13
Get BC
B(3,3), and C(3,-1)
BC = √(3-3)²+(-1-3)²
BC = √0²+-4²
BC= √0+16
BC = √16
BC = 4
Get AC
A(0,1), and C(3,-1)
AC = √(3-0)²+(-1-1)²
AC = √3²+(-2)²
AC = √9+4
AC= √13
Since AB = AC, this shows that the triangle ABC is an isosceles triangle.
The two sides that are congruent are AB and AC

By rounding to 1 significant figure, estimate
542.04 × 1.88
By rounding to 1 significant figure 542.04 × 1.88 equal to 1019.0352
is 1019.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given we have to round off 542.04×1.88 = 1019.0352.
Now rounding off to one significant digit means we should have only one digit after the decimal place and the second digit after the decimal place is 3 which is less than 5.
∴ 1019.0352 rounded off to one significant digit is 1019.

triangle KLM ~ triangle KCD are similar. Solve for x.
Answer:
x=14
Step-by-step explanation:
28/16 = 1.75
1.75 is the constant of proportionality
63/1.75 = 36
therefore, 2x+8 should be equal to 36
2x+8 = 36 >> subtract 8 from both sides
2x = 28 >> divide both side by 2 to get x alone
x = 14
