7 is 1/10 of 70 because 7 times 10 equals 70
Answer:
There are a total of 32 Green marbles
Step-by-step explanation:
Let R represent the number of red marbles
Let G repersent the number of green marbles
Write down what is given
G+R=47
Write down what G can also be
G=2R+5
Substitute:
2R+5+R=47
Combine like terms (Algebra)
3R+5=47
Subtract 5 from both sides
3R=42
Simplify
R=14
Substitute the value of R in the equation for G
G=2(14)+5
Solve/Algebra
G=28+5
Solve/Algebra
G=32
Answer:
D
Step-by-step explanation:
Because first you need to make the equation negative because X^2 need to be positive (easier to do)
x^2-6x-m
What times to -6 are
(2times-3) (-2 times -3)
(1times -6) and (-1times 6)
neither of these will be above 9 so d is correct
