Answer 1

Answer:

45

25 ÷ 45 = 0.555 x 81 = 45

Answer 2

Answer:

A 45-foot tree will cast a 81-foot shadow.

Step-by-step explanation:

Set up a proportion.

I'll set mine up like this:

[tex]\frac{Height of Tree}{Shadow}=\frac{Height of Tree}{Shadow}[/tex]

Insert the values given then solve for the unknown (t).

[tex]\frac{25}{45}=\frac{t}{81}[/tex]

[tex](81)\frac{25}{45}=\frac{t}{81}(81)[/tex]

[tex]45=t[/tex]

x= 5

y= -4

Step-by-step explanation:

x= 17+3y so you substitute what you got for x in so

17 +3y +7y = -23

10y=-40

y=-4 now you put -4 in for y in the first equation

x = 17 + (3 times -4)

A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7, and tickets cost $28.50 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.

Answers

228/28.50= 8 that should be right!

The solution of the inequality for the number of people (p) who can go to the amusement park will be;

⇒ p < 8

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

They have no more than $235 to spend on parking and admission.

And, Parking is $7, and tickets cost $28.50 per person, including tax.

Now,

Let the number of people who can go to the amusement park = p

So, We can formulate;

⇒ 28.50p + 7 < 235

Solve for p as;

⇒ 28.50p < 235 - 7

⇒ 28.50p < 228

⇒ p < 228/28.50

⇒ p < 8

Thus, The solution of the inequality for the number of people (p) who can go to the amusement park is;

⇒ p < 8

5 + x = 3(x - 7) + 6

Answers

Answer:

x=10

Step-by-step explanation:

x+ 5= 3x - 21 +6

x+5 = 3x - 15

20= 2x

X=10
The reason for this is you distribute the 3 giving you 5+x=3x-21+6.
Then add the 6 to make 5+x=3x-15
Add 15 on both sides to make 20+x=3x
Subtract x on both sides to be 20=2x
Divide both sides by 2 to make 10=x

Answers

y+4x+7 is the answer

Answer:

y = -4x - 17

Step-by-step explanation:

y + 1 = -4 (x + 4)

First, distribute the -4

Then subtract 1 from both sides to make the equation y=

y = -4x - 17

This makes the equation standard form
