Answer:

<2 = 116 degrees

Step-by-step explanation:

alright so if angle 1 is 64 and you need to find angle 2 you gotta think about whats similar between them. They're both on the same line(railroad) and a straight line is 180 degrees. So now with this info all u gotta do is subtract 180-64 to get 116

Marla has $4.55 in dimes and quarters. If she has 7 more quarters than dimes, how many quarters does she have?

Natalka [10]

Answer:

She have <u>15 quarters</u>.

Step-by-step explanation:

Given:

Marla has $4.55 in dimes and quarters.

Now, to find the quarters she have, if she has 7 more quarters than dimes.

Let the number of dimes be $x$ .

And the number of quarters be $7+x$ .

As the value of dime = $0.10.

And the value of quarter = $0.25.

So, according to question:

⇒ $0.10x+0.25(7+x)=4.55$

⇒ $0.10x+1.75+0.25x=4.55$

⇒ $0.35x+1.75=4.55$

<em>Subtracting both sides by 1.75 we get:</em>

⇒ $0.35x=2.8$

<em>Dividing both sides by 0.35 we get:</em>

⇒ $x=8$

Thus, the number of dimes = 8.

And the number of quarters = $7+x$ = 7+8 = 15.

Therefore, she have 15 quarters.

The perimeter of a flower garden with three sides is 46 feet. One side of the garden is 11 feet long. Another side of the garden

saul85 [17]

Answer:

Step-by-step explanation:

Step one:

given that the orientation of the garden is a triangular shape(it has three sides)

the perimeter is given as=46ft

one side y=11ft

the second side z= 13ft

let the third side be xft

Step two:

the expression for the perimeter = z+y+x

46=11+13+x

46=24+x

solve for x

x=46-24

x=22ft

Therefore the third side is 22ft long
