QUESTION POSTED AT 10/10/2019 - 07:34 PM

Kyle put "two" rectangles together to make this shape, so cut the shape into two. Then we know the bottom of one of the rectangles which is 16 is subtracted by 8 because half of 16 is 8 and 8 is one the measurements.

To figure this question out, you have to make the fractions have common denominators. The LCM (Least Common Multiple) of 3 and 4 (the denominators of the fractions) is 12.

3/4= 9/12 (Elaine) (Numerator times 3, Denominator times 3)

2/3= 8/12 (Jake) (Numerator times 4, Denominator times 4)

A. total cost of all the purchases

You can't calculate the sales tax on the sheet music or the change for $50 he would have received (which requires subtracting the total cost from $50) until you know how much the sheet music cost total.

The B) and C) options aren't relevant to the problem. You're trying to find the amount of change he gets after paying the total cost for all the sheet music + the tax on that.

2(2x - 4) + x = 7

Distribute the 2

4x - 8 + x = 7

combine like terms

5x - 8 = 7

add 8 to both sides

5x = 15

divide both sides by 5

x =3

CHECK

2(2*3-4) + 3 ?=? 7

2(6-4) + 3 ?=? 7

2(2) + 3 ?=? 7

7 = 7 CHECKS

Distribute the 2

4x - 8 + x = 7

QUESTION POSTED AT 17/10/2019 - 08:38 AM

Using the Theorem of Pythagoras (a² + b² = c²)

Put in the values:

10² + 10² = 15²

Is it correct? (solve)

Nope! Because 10² + 10² = 200, and the square root of 200 is about 14, not 15.

The answer is no, the side lengths 10, 10, and 15 cannot form a triangle.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

This is the concept of algebra, to get the inequality we proceed as follows; Erma subtracted 8 from both sides and divided both sides by 8 so that we can get the value of the unknown. The the properties used were:

Subtraction properties of inequality, which states that:

if a<b, then a-c<b-c

Division properties of inequality, which states that:

if a<b, then a/c=<b/c

Subtraction properties of inequality, which states that:

if a<b, then a-c<b-c

Division properties of inequality, which states that:

**Answer:**

**Step-by-step explanation:**

Given is a differential equation as:

We can solve this by separation of variables method

To find C:

Given y(0) =4

Substitute x=0 and y =4

sin inverse of 4 = C

But sin inverse is valid only for values between -1 and 1

Hence C is not a real value

No solution for this.
