Answer:
$306 go to the school
Step-by-step explanation:
2.15*600 = 1290
0.45*600 = 270
subtract :
1290- 270 = 1020
$1020 made
1020* 30% = 1020 * 0.30
1020* 0.30 = 306
so
$306
If you rent a canoe for 3 hours, you will pay $45.
Write a linear equation to represent the total cost (y) of renting the canoe for x hours.
Answer:
y = 15x
Step-by-step explanation:
I'm assuming there is no up-front cost. This means that per hour, you need to pay $45/3 = $15, since $45 is for 3 hrs.
y = 15x
Hope this helps!

A zebra runs 15 miles per hour faster than an elephant. The zebra runs 8 miles in
the same time that an elephant runs 5 miles. Write and solve an equation to
calculate the speed of each animal.
Answer:
elephant: 25 mph; zebra: 40 mph
Step-by-step explanation:
The time required is the same in each case, so we need to set up an equation of the form distance1/speed1 = distance2/speed2:
8 miles 5 miles
------------- = time = -------------
speedz speede
From this we get:
8 5
------------------ = -------------------
speede + 15 speede
Cross multiplying, we get: 8(speed e) = 5(speede) + 75, or
3(speede) = 75, or
speede = 25 mph
Then speedz = 25 mph + 15 mph = 40 mph = speedz

Answer:
x = 14
Step-by-step explanation:
Since, given Pentagons are similar because their measures of internal angles are same. So, their corresponding sides would be in proportion.
[tex] \frac{x + 4}{x} = \frac{9}{7} \\ \\ \frac{x + 4 - x}{x} = \frac{9 - 7}{7} \\ \frac{4}{x} = \frac{2}{7} \\ \\ \frac{2}{x} = \frac{1}{7} \\ \\ x = 2 \times 7 \\ \\ x = 14[/tex]

Question 5
Reduce in LOWEST terms: 4 dimes and 2 nickels
Answer:
2 quarters
Step-by-step explanation:
4 dimes = 40 cents
2 nickels = 10 cents

Find the length of the variable w
Answer:
w = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{BD}{BA}[/tex] = [tex]\frac{DE}{AC}[/tex] , substitute values
[tex]\frac{w}{w+2}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5w = 3(w + 2) ← distribute
5w = 3w + 6 ( subtract 3w from both sides )
2w = 6 ( divide both sides by 2 )
w = 3

PLS HELP pls pls pls
Answer:
y=0
Step-by-step explanation:
Simplifying
y + y = 0
Combine like terms: y + y = 2y
2y = 0
Solving
2y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 0
Simplifying
y = 0
