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.

Elaine brought more salad to the picnic.
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)

Which calculation should be completed first to solve this story problem? Allister bought some sheet music. He bought 6 songs for $0.99 each and 1 book for $16.99. He paid $1.38 in sales tax. He gave the cashier $50. How much change should Allister get? A. total cost of all the purchases B. total cost of 6 songs C. sum of the cost of 1 song, the book, and the tax D. the change

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 solve by combining like terms show all steps plz

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

Veda solves the following system of linear equations by elimination. What is the value of x of the solution? A –20 B –1 C 1 D 20

we have

6+4x-2y=0 -----> equation A

-3-7y=10x -----> equation B  

Multiply equation A by -3.5 both sides

-3.5(6+4x-2y)=-3.5*0

-21-14x+7y=0 ------> equation C

Adds equation C and equation B

-21-14x+7y=0 \\-3-7y=10x\\ ---------\\-21-14x+7y-3-7y=10x

-24-14x=10x\\ 14x+10x=-24\\ 24x=-24\\x=-1

therefore

the answer is the option B

x=-1

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

Solve the triangle: a = 10, b = 10, c = 15. If it is not possible, say so

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.

QUESTION POSTED AT 17/10/2019 - 08:12 AM

A. Solve the differential equation y prime equals the product of 4 times x and the square root of the quantity 1 minus y squared. b. Explain why the initial value problem y prime equals the product of 4 times x and the square root of the quantity 1 minus y squared with y(0) = 4 does not have a solution.

Answer:

Step-by-step explanation:

Given is a differential equation as:

y'=4x\sqrt{1-y^2}

We can solve this by separation of variables method

\frac{dy}{\sqrt{1-y^2} } =4xdx\\sin^{-1} y = 2x^2+C

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.
