Answer:
Messina has prepared 36 stickers and 8 students are in her class.
Step-by-step explanation:
Difference in remainder = 12 + 4
= 16
Difference per student = 5 - 3
= 2
No. of students = 16 ÷ 2
= 8
No. of stickers = 8 × 3 + 12 or 8 × 5 - 1
= 36
Answer:
17
Step-by-step explanation:
Both sides of the triangle are equal in length and segment SR is 17, so b must also be 17
Answer:
(8 - 12 )
Step-by-step explanation:
Given
x - y = 8
x + y = - 5
Multiply both equations through by 4 to clear the fractions
x - 2y = 32 → (1)
2x + 3y = - 20 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the x- term
- 2x + 4y = - 64 → (3)
Add (2) and (3) term by term to eliminate x
0 + 7y = - 84
7y = - 84 ( divide both sides by 7 )
y = - 12
Substitute y = - 12 into either of the 2 equations and solve for x
Substituting into (1)
x - 2(- 12) = 32
x + 24 = 32 ( subtract 24 from both sides )
x = 8
solution is (8, - 12 )
Answer:
6x+50
Step-by-step explanation:
5(x+10)+x=5x+50+x=6x+50
I believe the answer is 5t
6s7t-6s2t = 5t
