\(2+x:5=-3\\\Rightarrow x:5=-3-2\\\Rightarrow x:5=-5\\\Rightarrow x=-5\cdot5=-25\)

\(2+x:5=-3\)

\(=>x:5=\left(-3\right)-2\)

\(=>x:5=-5\)

\(=>x=\left(-5\right):5\)

\(=>x=-1\)

Diện tích thửa ruộng hình chữ nhật đó là: 54 x 9 = 486(m²)

Số ki-lô-gam thóc thu hoạch được trên thửa ruộng đó là: 486 : 2 x 16 = 3888(kg thóc)

Đ/số: 3888 kg thóc

Diện tích thửa ruộng:54x9=486m2

Số kg thóc thu đc là 496:2x16=4,528

a) Nhiệt độ dự báo ngày hôm sau là: (-13) + 3 = (-10)(độ C)

Gọi số học sinh khối 6 của trường đó đi thăm quan dã ngoại là x ( x ϵ N^* ' 500 ≤ x ≤ 700)
Theo đề bài ta có: x ⋮ 12
                              x ⋮ 18     → x ϵ BC(12, 18, 30)
                              x ⋮ 30
12=2 mũ 2 x 3
18=2 x 3 mũ 2
30=2 x 3 x 5
BCNN(12,18,30)=2 mũ 2 x 3 mũ 2 x 5 = 180
xϵBC(12,18,20)=B(180)= 0 ; 180 ; 360 ; 540 ; ....
Mà  500 ≤ x ≤ 700 nên x=540
Vậy số học sinh khối 6 của trường đó đi thăm quan dã ngoại là 540 học sinh

Từ trang 1 đến trang 9 cần 9 chữ số

Từ trang 10 đến trang 99 cần số chữ số là :

        $(99-10+1)\times 2=180$ ( chữ số )

Từ trang 100 đến trang 482 cần số chữ số là :

        $(482-100+1)\times 3=1149$ ( chữ số )

Từ trang 1 đến trang 482 cần số chữ số là :

        $9+180+1149=1338$ ( chữ số )

   Vậy Lan cần viết tất cả 1338 chữ số

\(1,75\times y:16,8=1,25\\1,75\times y=1,25\times16,8\\1,75\times y=21\\y=21:1,75\\y=12\)

\(7^{2x-6}=49\)

\(=>7^{2x-6}=7^2\) hoặc \(7^{2x-6}=\left(-7\right)^2\)

\(=>2x-6=7\) hoặc \(2x-6=-7\)

\(=>2x=7+6\) hoặc \(2x=\left(-7\right)+6\)

\(=>2x=13\) hoặc \(2x=-1\)

\(=>x=\dfrac{13}{2}\) hoặc \(x=-\dfrac{1}{2}\)

Vậy \(x=\dfrac{13}{2}\) hoặc \(x=\dfrac{-1}{2}\)

\(#NqHahh\)

\(7^{2x-6}=49\)

\(\Rightarrow7^{2x-6}=7^2\)

\(\Rightarrow2x-6=2\)

\(\Rightarrow2x=2+6\)

\(\Rightarrow2x=8\)

\(\Rightarrow x=8:2=4\)
