trialgle area=
we need to find base
13-4-4=5
base=5
height=6

Mr. Gonzales has only $42.50 to spend at a clothing store. He wants to buy a shirt that costs $29, including tax, and some bracelets that cost $4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mr. Gonzales could buy. Equation _____________________. Solve the equation to determine the number of bracelets Mr. Gonzales could by. Show your work. Answer _____________________ bracelets

Answers

Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3

Step-by-step explanation:

The data we have is:

Gonzales has $42.50

He wants to buy:

a shirt that costs $29

some bracelets that cost $4.50 each.

The equation that we need to solve is:

Total cost = money that Gonzales has.

The cost is $29 + x*$4.50

where x is the number of bracelets he can buy.

The equation that we need to solve is:

$29 + x*$4.50 = $42.50

to solve it we must isolate x:

x*$4.50 = $42.50 - $29 = $13.50

x = 13.50/4.50 = 3

So we have that Mr. Gonzales can buy a total of 3 bracelets.

y=4.5x+29 put y=0 so you can solve
0=4.5x+29 minus 29 on both sides to cancel it out
-29=4.5x divide by 4.5 on both sides to find x
-6.44444...=x round to nearest whole number which would be 6 bc he can't have 6.44444 bracelets

Alaska has a land area of about 1,700,000 square kilometers Florida has a land area of 1/10 the size of Alaska what is the land area of Florida explain how you found your answer.

Answers

Since Florida is 1/10 of the size of Alaska, all you need to do is 1,700,000 ÷ 10. Florida's area is 170,000 km². I hope that helps!
area of Florida is 1/10 the size of Alaska.
area of Alaska = 1,700,000 km^2
area of Florida = (1/10) × 1,700,000 = 170,000 km^2

adjecent basically means "next to"  and perpindicular is meeting at an right angle (90 degrees) so squares have them and right angle triangles do to.
