2(y+2)-y=3(y-1)+9 I am solving for y​

Answers

Answer 1

Answer:

y = -1

Step-by-step explanation:

Step 1: Write equation

2(y + 2) - y = 3(y - 1) + 9

Step 2: Solve for y

Distribute: 2y + 4 - y = 3y - 3 + 9Combine like terms: y + 4 = 3y + 6Subtract y on both sides: 4 = 2y + 6Subtract 6 on both sides: -2 = 2yDivide both sides by 2: -1 = yRewrite: y = -1

Step 3: Check

Plug in y to verify it's a solution.

2(-1 + 2) - (-1) = 3(-1 - 1) + 9

2(1) + 1 = 3(-2) + 9

2 + 1 = -6 + 9

3 = 3

Answers

Answer:

x=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(3x+8)=175

(5)(3x)+(5)(8)=175(Distribute)

15x+40=175

Step 2: Subtract 40 from both sides.

15x+40−40=175−40

15x=135

Step 3: Divide both sides by 15.

15x/15=135/15

x=9

-7x+5y=-8
9x-8y=15

Answers

Answer is (-1,-3)
Step by step explanation:
Solving for x:
-7x+5y=-8
Multiply both side’s by 8
-56x+40y=-64

9x-8y=15
Multiply both sides by 5
45x-40y=75

Subtract
-56x+40y=-64
45x-40y=75
-11x=11
-11x/-11 = 11/-11
x=1

Substitute -1 for x to get y
-7(-1)+5y=-8
Multiply 7 and -1
7+5y=-8
Then subtract 7 from both sides
5y=-15
Then divide both sides by 5
Y=-3

I’ve been able to figure out the rest of the questions but this one has me stumped. I need to solve for x. Can someone please write the steps down so I can learn what to do?

Answers

explanation:
x+91 and x+111 are supplementary angles (they add up to 180), so you would set an equation by adding both of them to equal 180:
x + 91 + x + 111 = 180
add like terms
2x + 202 = 180
subtract 202 from both sides
2x = -22
divide both sides by 2 to get the answer:
x = -11

Answer:

X= -11

Step-by-step explanation:

Combine the two equations to equal a supplementary line

(X+91)=(x+111)=180

Solve for x by reversing the equation

(x)+(x)=(180-91)+(-111)

x=-22/2

x=-11

then check it

you purchase 3 t-shirts and a booklet for 90$. the booklet cost 15. how much is each t-shirt? please help ! thank u

Answers

Answer:

each t-shirt was $25

Step-by-step explanation:

90 minus 15 = 75

75 divided by 3 equals 25

Answer:

25

Step-by-step explanation:

3t+15=90

3t=75

t=25

t represents the price for one t-shirt. 90 is the total amount and if the booklet is 15 dollars, altogether they equal 90. With this equation you are trying to isolate the variable (t), so subtract 15 because the opposite of 15 is -15. Then divide that by 3 because 3t is also 3 times t and the opposite of times is division.

Bruce Church, Inc. is a company engaged in extensive commercial farming in Arizona and California. A provision of the Arizona Fruit and Vegetable Standardization Act requires that all cantaloupes grown in Arizona "be packed in regular compact arrangement in closed standard containers approved by the supervisor." Arizona, through its agent Pike, issued an order prohibiting Bruce Church from transporting uncrated cantaloupes from its range in Parker, Arizona, to nearby Blythe, California, for packing and processing. It would take many months and $200,000 for Bruce Church to construct a processing plan int Parker. Further, Bruce Church had $700,000 worth of cantaloupes ready for transportation. Bruce Church filed suit in federal district court challenging the constitutionality of the Arizona statutory provision on shipping cantaloupes. The court issued an injunction (essentially saying the statute was not constitutional) against the enforcement of the act on the grounds that it was an undue hardship on interstate commerce.
