Tomas use balloons = 1.6 per minute
Step-by-step explanation:
a).
180 minutes = 36 sculpture
5 minutes to make a sculpture
b).
288 balloons = 36 sculpture
8 Balloons to make a sculpture
c).
288 Balloons = 180 minutes
1.6 Balloons per minute
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4
Answer:
The answer is 25
Step-by-step explanation:
Answer:
<u>The solution for the equation is x equal to -16</u>
Step-by-step explanation:
Let's find the solution for x in the equation given:
x/2 + 3 = -5
Multiplying by 2 at both sides of the equation, we have:
x + 6 = -10
Subtracting 6 at both sides of the equation, we have:
x + 6 - 6 = - 10 - 6
x = - 16
<u>The solution for the equation is x equal to -16</u>

The answer is here
let be L the length of each ramp
so the <span>the length of the entire dog walk, including both ramps is D, such that
</span>D=L + L + d, where d=12ft
L=hypotenus, and sin30° = 4.5ft x L so L= sin30° / 4.5= 1/2x 4.5=2.25ft
D=2.25ft+2.25ft +12ft=16.5ft
