Question

Какие числа следует подставить вместо букв a,b и c что бы все равенства оказались верными: 42/7= a/12, 42/6=b/14, 42/21=c/6 Помогите очень надо

Answer 1

A = 42*12/7 = 72
b = 42*14/6 = 98
c = 42*6/21 = 12

Answer 2

Solving for a, b, and c in the Equations

To solve for the values of a, b, and c that make the given equations true, we can start by rearranging the equations to solve for each variable.

1. Equation 1: 42/7 = a/12 2. Equation 2: 42/6 = b/14 3. Equation 3: 42/21 = c/6

Solving for a:

From Equation 1, we can solve for a: 42/7 = a/12 a = (42/7) * 12 a = 6 * 12 a = 72

Solving for b:

From Equation 2, we can solve for b: 42/6 = b/14 b = (42/6) * 14 b = 7 * 14 b = 98

Solving for c:

From Equation 3, we can solve for c: 42/21 = c/6 c = (42/21) * 6 c = 2 * 6 c = 12

Therefore, the values of a, b, and c that make the given equations true are: - a = 72 - b = 98 - c = 12
