Question

-28+20:(-4) 4.8 умножить 6,37+4,8 умножить 3.63

Answer 1

-28 + 20 / (-4) = -28 - 5 = -33
4.8 * 6.37 + 4.8 * 3.63 = 4.8 * (6.37 + 3.63) = 4.8 * 10 = 48

Answer 2

Let's solve the expressions step by step:

1. -28 + 20 : (-4) To simplify this expression, we need to perform the division before addition and subtraction. First, we divide 20 by -4, which gives us -5: -28 + 20 : (-4) = -28 + (-5) Now we can add the two numbers: -28 + (-5) = -33

Therefore, -28 + 20 : (-4) equals -33.

2. 4.8 * 6.37 + 4.8 * 3.63 We can use the distributive property of multiplication over addition to simplify this expression. First, we multiply 4.8 by 6.37, which gives us 30.576: 4.8 * 6.37 = 30.576

Next, we multiply 4.8 by 3.63, which gives us 17.424: 4.8 * 3.63 = 17.424

Now we can add the two results: 30.576 + 17.424 = 48

Therefore, 4.8 * 6.37 + 4.8 * 3.63 equals 48.
