Question

Решите уравнения R:98-87=1917 (20018-1986):a+16,если a=98,a=49

Answer 1

Может так но я не уверена

Answer 2

R÷98-87=1917

R÷98=1917+87

R÷98=2004

R=2004×98

R=196392

196392÷98-87=1917

1917=1917

(20018-1986)÷a+16 при а=98

18032÷а+16=18032÷98+16=184+16=200

при а=49

18032÷а+16=18032÷49+16=368+16=384

Answer 3

To solve the equations, we will substitute the values of "a" and evaluate the expressions.

1. For a = 98: R: 98 - 87 = 1917

We need to find the value of "R." Let's solve for R:

R = 1917 + 87 - 98 R = 1906

So, when a = 98, the value of R is 1906.

2. For a = 49: 20018 - 1986 : a + 16

Now, let's solve for the expression when a = 49:

20018 - 1986 : 49 + 16

First, perform the division:

20018 - (1986 / 49) + 16

Now, calculate the division:

20018 - 40.5306 + 16

Finally, perform the subtraction and addition:

20018 - 40.5306 + 16 ≈ 19993.4694

So, when a = 49, the value of the expression is approximately 19993.4694.
