The 9/5 put into a decimal is 1.8 so 1.8 times 100 is 180
Step-by-step explanation:
4x + 8y = 40
4x + (8×0.8) = 40
4x + 6.4 = 40
4x = 33.6
4x÷4 = 33.6 ÷ 4
x = 8.4
Answer:
Some flowers and some shading in it
-3x-1 = 2-(-3)
-3x-1 = 2+3
-3x-1 = 5
-3x = 5+1
-3x = 6
x = 6/(-3)
x = -2
4 and 5
4^2= 16
5^2= 25
Square root of 21= 4.5
