Answer:
Streamers are $2.50 each
Balloons are $1.50 each
Step-by-step explanation:
Make a system of equations
3s + 15b = 30
2s + 4b = 11
Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.
6s + 30b = 60
-6s -12b = -33
18b = 27
b = 1.5
Plug in 1.5 as b to find s
3s + 15(1.5) = 30
3s +22.5 = 30
3s = 7.5
s = 2.5
The streamers are $2.50 and the balloons are $1.50
Answer:
A
Step-by-step explanation:
Divide both sides with -16. ALWAYS remember that if you divide any number with a negative number, this "< ≤ > ≥" symbols have to change to the opposite direction
Answer
Find out the percentage of students from the north side of the city in the program .
To prove
Formula

As given
A magnet school program was set up to bring in students from all over the city. With the first 112 students .
the magnet program had 50% from the south side of town, 12.5% from the north side l, and 37.5% from the east side.
12 .5 % is written in the decimal form.

= 0.125
North side student be = 0.125 × 112
= 14
As given
If 6 more student from the north side and 2 students from the west side side enrolled in the program .
than north side student becomes = 14 + 6
= 20
Total number of student becomes = 112 + 6 + 2
= 120
put in the above formula


= 16.66% (approx)
Therefore 16.66% (approx) students from the north side of the city in the program .
Hey there! Just subtract 25 from 344. The answer is 319.
Answer:
34.8 + 6.879 = 41.679
The ratio of boys to girls in the school’s choir is 3:4. If there
are 12 girls in the choir then there are 9 boys
