Answer:

Step-by-step explanation:

y = 6x + 3   --------------(I)

x + 2y = 5       -------------(II)

substitute y = 6x + 3 in equation (II)

x + 2*(6x + 3) = 5

x + 2*6x + 2*3 = 5

x + 12x + 6  = 5

     13x + 6 = 5

If a ∝ b and a = 18 when b = 3, then find a when b = 5.
Elden [556K]

"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that

a = kb

We're given that a = 18 and b = 3, so that

18 = 3k   ⇒   k = 6

Then when b = 5, we would have

a = 6 × 5 = 30

How do you estimate 10.43
Veronika [31]

Answer:

Step-by-step explanation:

Given 10.43, you can 'estimate' it only by rounding off:

10.43 to the nearest tenth is 10.4.

10.43 to the nearest whole number is 10; we drop the fraction 0.43.
