X less than or equal to 8. This is because she can only have up to eight. To write the less than or equal to sign it is a less then sign with a line under it. Hope this helped!
3 km = 3000m
600m:3000m divide by 10
60:300 divide by 10
6:30 divide by 3
2:10 divide 2
*1:5* (simplest form)
Step-by-step explanation:
so you put the value of F into x and make an equation
Take 37% as an example, just add a decimal point to the left 2 times. Decimal = .37. Fraction would be 37/100, because you cannot simplify.
Y = x - 7....so sub in x - 7 for y in the other equation
5x + 2y = 7
5x + 2(x - 7) = 7
5x + 2x - 14 = 7
5x + 2x = 7 + 14
7x = 21
x = 21/7
x = 3
y = x - 7
y = 3 - 7
y = -4
solution is (3,-4)
