Answer:106
Step-by-step explanation:
Let number of white marbles be w
Let number of red marbles be r
w+r = 126---------1
w = 6 +5r-----------2
Put eqn 2 in eqn 1
6+ 5r + r = 126
6 + 6r = 126
6r = 120
r = 20
w = 6 +5r =6+100
= 106

Answer:
- perimeter ratio: 4 : 3
- area ratio: 16 : 9
Step-by-step explanation:
The ratio of perimeters is the ratio of corresponding sides.
first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters
The ratio of areas is the square of the ratio of linear dimensions.
first : second = 4² : 3² = 16 : 9 . . . ratio of areas
Okay!
1) Round both numbers -
2674 - 2700
1847 - 1800
2) Subtract 2700 and 1800
2700 - 1800 = 900
Therefore, the answer is 900
Answer:
Simplify the expression:
1x+10y=4+3
Step-by-step explanation:
1 : x+10y=4+3
x+10y=4+3
x+10y=7
x+10y-10y=7-10y
x=7-10y
