Số số hạng là :
( 50 - 5 ) : 5 + 1 = 10 ( số )
Tổng trên là :
( 50 + 5 ) . 10 : 2 = 275
Vậy,.............
\(\text{A= 73 - (35 + 1𝑎) : 23}\)
thay \(a=45\) vào biểu thức ta có:
\(A=73-\left(35+45\right):23\)
\(=73-\frac{80}{23}=\frac{1599}{23}\)
b)\(73-\left(35+1a\right):23=1715\)
\(\left(35+1a\right):23=-1642\)
\(35+a=-37766\)
\(a=-37801\)
\(a.13.\left(78+22\right)=13.100=1300\)
\(b.25.70+28.25+25.2=25.\left(70+28+2\right)=25.100=2500\)
\(c.\dfrac{15.3.14.2.19}{19.14.15}=6\)
\(d.\dfrac{132.70.60}{12.35.20}=\dfrac{11.12.35.2.20.3}{12.35.20}=66\)
Spring is a time for doing things. It seems everyone is full of energy. The days become warmer so everyone spends more time outside. Winter is finishing, so the countryside becomes greener.
I love watching the new flowers in my garden in spring. I watch the tulips grow and then I know winter is over. I wonder what it’s to live in countries that don’t have four seasons.
They miss out on what it’s to welcome spring and see everything come alive. Spring has to be the best season. It definitely makes you feel very positive about life.
It’s a good time to clean your house from top to bottom. We call this spring cleaning. Spring also means the weather gets warmer and you can do more things outside.
The rain season usually from June to November, it rains a lot and wet. In this time, it usually have hurricane and thunderstorm. So, you need to be careful when you go outside because the rain might cause thunder or lightning, you cannot use a phone, under the tree and no umbrella. Thankfully, the rain season it's good for crops.
The dry season, it's very hot. The temperature it's about 36-40 degree Celsius and it usually from the end of January to May. In this time, the weather it's very muggy and easily to get fire.
I live in the dry season now. So, I'm dying for a lot of rains. To me, I think I the rain season the most because the rain season bring the cool weather and convenience for the crops.
\(\left(35-x\right)-70=-45\)
\(\Rightarrow35-x=-45+70\)
\(\Rightarrow35-x=25\)
\(\Rightarrow x=35-25\)
\(\Rightarrow x=10\)
\(\left(-22\right)\cdot\left(-5\right)>0\)
\(\left(-7\right)\cdot20< -7\)
(-22).(-5)và 0
do 2 số nguyên âm nhân với nhau ra số nguyên dương nên ta có thể rút gọn biểu thức thành 22.5 và 0 từ đó => 22.5>0
(-7).20 < -7
(-39).12 = 39.(-12)
(35-15).(-4)+24(-13-17)=30.(-4)+24(-13-17)=-120+24.30=-120+720=600
(-13)(57-34)+57(13-45)=-13.57-(-13).34+57.13-57.45=13.(-57)-13.(-34)+57.13-57.45=13(-57-(-34)+57)-57.45=13.34-57.45=442-2565=-2123
Bài giải
Số xe 35 chỗ và số xe 45 chỗ là:
Công thức: 480 ÷ (35 + 45) = 6 (xe)
Nếu như dư thì bạn biết là phải thêm 45 hoặc 35
Vậy cách trên tiết kiêm nhất với số tiền là:
6 × (500 000 + 600 000) = 6 600 000
Đáp số:...
a) (190-2x) : 35 -32 = 16
=> (190-2x) : 35 =16+32
=> (190-2x) : 35 =48
=> 190-2x = 48.35 = 1680
=> 2x = 190-1680 = -1490
=> x = -1490/2= -745
b) (x : 23 + 45) . 37 -22 =2^4.105
=> (x : 23+45).37=2^4.105+22=1702
=> (x : 23 +45) = 1702/37 = 46
=> x : 23 = 46- 45 =1
=> x = 23
a) ( 190 - 2x ) : 35 - 32 = 16
( 190 - 2x ) : 35 =48
190-2x=1680
2x=-1490
x=-745
b) ( x : 23 + 45) . 37 - 22 = 24 . 105
( x : 23 + 45) . 37 - 22 = 1680
( x : 23 + 45) . 37 =1702
x : 23 + 45= 46
x:23=1
x=23
45 + 45 + 45 + 45 / 35 + 35 35 = 865618/243
\(\frac{4^5+4^5+4^5+4^5}{3^5+3^5+3^5}=\frac{\left(4+4+4+4\right)^5}{\left(3+3+3\right)^5}=\frac{16^5}{9^5}=\frac{\left(2^4\right)^5}{\left(3^2\right)^5}=\frac{2^{20}}{3^{10}}\)
