Question

1) (3+c)÷14=5,c=682)1,5(y+9)+3,5, y=4​

Answer 1

Ответ:

1) 71/14=5 неверно

1,5*13+3,5=19,5+3,523.

Answer 2

Let's solve each equation one by one:

1. (3 + c) ÷ 14 = 5

To solve for c, first, we want to isolate c on one side of the equation.

Multiply both sides of the equation by 14 to get rid of the fraction:

(3 + c) = 5 * 14

Now, simplify the right side:

(3 + c) = 70

Next, subtract 3 from both sides to isolate c:

c = 70 - 3

c = 67

So, the solution for c is c = 67.

2. 1.5(y + 9) + 3.5 = 4

To solve for y, first, distribute 1.5 on the left side of the equation:

1.5y + 1.5 * 9 + 3.5 = 4

Now, simplify the left side:

1.5y + 13.5 + 3.5 = 4

Combine like terms on the left side:

1.5y + 17 = 4

Next, subtract 17 from both sides to isolate 1.5y:

1.5y = 4 - 17

1.5y = -13

Finally, divide both sides by 1.5 to solve for y:

y = -13 / 1.5

y = -8.67

So, the solution for y is approximately y = -8.67.
