Step-by-step explanation:
55% of the tables would be 33 tables times 10 chairs equals 330 Chairs That mean 60 Tables -33 tables Leaves you with 27 tables Times 8 Chairs Equals 216 Chairs So 330 and 216Equals 546 chairs
It's A because 7.5 is the starting point but it's not included so that point is circled.
5(5a+3)=14a-29 -- expand brackets
25a+15=14a-29 -- subtract 15 and subtract 14a from both sides
11a=-44 -- divide by 11
a=-4
Answer:
(3, 1 )
Step-by-step explanation:
Given the 2 equations
x + 2y = 5 → (1)
3x + 5y = 14 → (2)
Rearrange (1) expressing x in terms of y by subtracting 2y from both sides
x = 5 - 2y → (3)
Substitute x = 5 - 2y in (2)
3(5 - 2y) + 5y = 14 ← distribute and simplify left side
15 - 6y + 5y = 14
15 - y = 14 ( subtract 15 from both sides )
- y = - 1 ( multiply both sides by - 1 )
y = 1
Substitute y = 1 into (3) and evaluate for x
x = 5 - (2 × 1) = 5 - 2 = 3
Solution is (3, 1 )
Answer:
x=5 and y=2
