4. There are 2 whole numbers of different value. If you divide the large number by the small number, it gives you quotient 3 with remainder of 8. If you divide 3 times of the small number, ut gives you quotient 11 with remainder of 2. Fond 2 such whole numbers.
Jawaban:
35 and 113
Penjelasan dengan langkah-langkah:
x angka kecil, y angka besar
pernyataan pertama :
y = 3x + 8
pernyataan kedua :
x = 11×3 +2
x = 35
jadi y = 35×3 + 8
y = 113
5. Describe the relationship between the number of sides and the number of diagonals
Jawab:
The relationship between the number of sides and the sum of the angles in a polygon is that the sum of the angles of the polygon is equal to the sum of the sides minus 2 and then multiplied by 180°. Sum of angles = (n - 2) × 180°. With n as the number of sides of the polygon.

7. The sum of 40 % of number A and 30 % of number B is 6. The sum of 25 % of number A and 15% of number B is 5. Accordingly, what is the value of A?
40%A+30%B=6
----------------------- x 100
40A+30B=600
4A,+3B=60
25%A+15%B=5
---------------------- x 100
25A+15B=500
5A+3B=100
4A+3B= 60
------------------ -
A = 40
8. In a fruit stall, there are apples, bananas, blueberries and pears. The number of blueberries is 25% of the total number of fruits. The number of blueberries and bananas is the same and the number of pears is half the number of bananas. Find out the total number of fruits if there are 375 apples.
Jawab:
1000 fruits
Penjelasan dengan langkah-langkah :
apples = a , bananas = b , blueberries = bl , pears = p , fruits total = x
bl = b = 25% x
p = [tex]\frac{1}{2}[/tex] x 25% x = 12,5% x
a = 375
a + b + bl + p = x
375 + 25% x + 25% x + 12,5% x = x
375 + 62,5% x = x
375 = 37,5%x
x = 375 : [tex]\frac{37,5}{100}[/tex]
x = 1000

15. The ratio of the number of girls to the number of boys in a camp is 2 : 3. 65 girls left the camp and the ratio of the number of boys became 1 : 4. Find the total number of children at the camp at first
Penjelasan dengan langkah-langkah:
girl:boy =2:3 (let name it as unit )
after 65 girl left
girl :boy =1:4( let name this as part )
equation :
3unit =4part
2unit-65=1part
solve this equation
3u=4p
1u=4p/3
insert the unit
2u-65=1p
2(4p/3)-65= 1p
8p/3-65=1p
8p/3-1p=65
5p/3=65
p= 39
3u=4(39)
3 u= 156
1u=52

Jawab:
28
Penjelasan dengan langkah-langkah:
Ini kita bikin persamaan matematikanya dulu, ya. Baru dicari =
1/2x + 49 = 2 1/4x
1/2x + 49 = 9/4x (dikali 4)
2x + 196 = 9x
196 = 9x - 2x
196 = 7x
28 = x
