Answer:
1.) Squares: 6 Circles: 8
2.) Hexagon and Heptagon and Octagon
3.) 18/100
4.) 16
5.) 56$
6.) Area = l × w
= 7 × 3
= 21 inches^2
Step-by-step explanation:
63
Because, 100% of 70 would be 7. Now we have that number lets multiply it by 9 because of 90%. 9 x 7 = 63 first-graders
x = 7/3
4x - 2 = x + 3 + 2
4x - 2 = x + 5
Rearranging the terms, we get,
4x - x = 5 + 2
3x = 7
Hence, x = 7/3.
3y = ax + 7
3(4) = a(3) + 7
12 = 3a + 7
3a = 5
a = 5/3
