Answer:

x=7

y=2

Step-by-step explanation:

10 + 2x = -2y ➡y = -5-x

replace y with -5-x in the first equation

-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7

now use this information to find value of y

y - (-7)=9 ➡y = 2

Draw a diagram to match the equation 2(​w​ + 44) = 180. Then find the value of ​w​.
coldgirl [10]

Answer:

w = 46

Step-by-step explanation:

Let's solve your equation step-by-step.

2 (w + 44) = 180

Step 1: Simplify both sides of the equation.

2 (w + 44) = 180

(2) (w) + (2) (44) = 180 (Distribute)

2w + 88 = 180

Step 2: Subtract 88 from both sides.

2w + 88 − 88 = 180 − 88

2w = 92

Step 3: Divide both sides by 2.

2w /  2 =  92 /  2

<em>w = 46</em>

☺ Hello mate__ ❤

◾◾here is your answer...

i think right question is this

(3x − 7y)^2

ok now start solving:-

(3x − 7y)^2

=> (3x − 7y) (3x − 7y)

=> 3x(3x- 7y) -7y(3x-7y)

=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y

=> 9x^2 -27xy +27xy + 49y^2

=> 9x^2 + 49y^2

so your correct ans. is 9x2 + 49y2

➽━━━━━━━━━━━━━──➸

I hope, this will help you.☺

Thank you______❤

Jonathan bought a Gucci belt in Chinatown for $35.00. The belt was on sale for ⅓ off the regular price. Then, an additional 8% w
leonid [27]

Answer:

<u>The original price of the belt was $ 59.32 and Jonathan paid $ 35 for it.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount Jonathan paid for the belt = $ 35

Discount = 1/3 off the regular price

Coupon = additional 8% = 0.08

2. How much did the Gucci belt cost Jonathan? Show your work or explain how you know.

We assume the question is asking for the original price of the belt, then we make this calculation:

Amount Jonathan paid for the belt = (Original price - Discount) - Coupon

Replacing with the values we know:

Original price = x

35 = (x - 1/3x) - 0.08x

35 = 2/3x - 0.08x

35 = 0.67x - 0.08x

35 = 0.59x

x = 35/0.59

x = 59.32

<u>The original price of the belt was $ 59.32 and Jonathan paid $ 35 for it.</u>
