Answer:
23
Step-by-step explanation:
64 divided by 2 = 32
(32 - 9)=23
(32+9)= 41
Total=14+20+16=50
P(blue)=20/50=2/5
so, answer=(2/5)*40=16

Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
3x - 5y = - 9 → (1)
x + 2y = 8 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the x- term, that is
- 3x - 6y = - 24 → (3)
Add (1) and (3) term by term to eliminate x
(3x - 3x) + (- 5y - 6y) = (- 9 - 24), that is
- 11y = - 33 ( divide both sides by - 11 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting in (2)
x + 2(3) = 8
x + 6 = 8 ( subtract 6 from both sides )
x = 2
Solution is (2, 3 )
Total number = 30
1/5 of 30 = 1/5 x 30 = 6
The attached figures show the total number of filled
circles in five lines. Each line have “6” filled circles.
So 5 lines having 6 filled circles = 5 x 6 = 30
<span>Every line represents “1/5” of total amount “30”. Which
proved that 1/5 of 30 is equal to 6. </span>
