Câu 1: Trang 6 toán tiếng anh lớp 4Find the value of the expressions (follow the example):Tính giá...

Cách làm:

a. Given b = 4, plug in the value of b into the expression 6 - b.
6 - b = 6 - 4 = 2
Therefore, the value of the expression 6 - b when b = 4 is 2.

b. Given c = 7, plug in the value of c into the expression 115 - c.
115 - c = 115 - 7 = 108
Therefore, the value of the expression 115 - c when c = 7 is 108.

c. Given a = 15, plug in the value of a into the expression a + 80.
a + 80 = 15 + 80 = 95
Therefore, the value of the expression a + 80 when a = 15 is 95.

Đáp án:

b. If c = 7 then 115 - c = 115 - 7 = 108
c. If a = 15 then a + 80 = 15 + 80 = 95
