<h2>Answer:</h2>

y = 5

<h2>Step-by-step explanation:</h2>

<em>Solution:</em>

7y = 5y + 10

7y - 5y = 10

2y = 10

\frac{2y}{2} = \frac{10}{2}

y = 5

<em>Checking:</em>

7y - 5y = 10

7(5) - 5(5) = 10

35 - 25 = 10 ✓

Find the missing side of a right triangle a b c
iren2701 [21]

Answer:

Use Pythagorean Theorem.

Step-by-step explanation:

To find any side of a right angled triangle, we use Pythagorean Theorem. It states that the square of hypotenuse is equal to the sum of squares of it's sides.

Let hypotenuse is a

Perpendicular is b

and base is c

According to the theorem:

a²= b² + c²

Add values and solve for the unknown variable / side.

If you had added the problem, I would have elaborated more but still this will help you out.

a triangular flower bed needs a thin metal border all the way around it. The sides are 7 feet, 6 feet, and 9 feet long.
kotegsom [21]
Excuse my awful triangle drawing skills, haha..
So essentially you need to find the perimeter which is done by adding the lengths of the sides.. this gives you 22ft.
Then for part b you need to convert 22ft to yards which gives you 7.3 yards.
Since you can only buy a whole number of yards, you'll actually need 8 yards.
So if the boarder is $8.75 per yard, and you need 8 yards, how much would it cost?
Hope this was helpful.

Solve for a<br> -8 = a(2+5)^2 +41<br> A. -1<br> B. 1<br> C. -2<br> D. 2
mario62 [17]

Answer:A

Step-by-step explanation:

-8=a(2+5)^2 + 41

-8=a x 7^2 + 41

-8=a x 7 x 7 +41

-8=49a+41

Collect like terms

-8-41=49a

-49=49a

Divide both sides by 49

-49/49=49a/49

-1=a

a=-1
