Answer:
b) 7 over 12 or (7/12)
Step-by-step explanation:
The number of white roses = 5
Therefore,
The number of pink roses= 12-5
= 7
So the fraction will be
Pink roses/ total roses
= 7/12
Answer:
6 2/3 minutes
Step-by-step explanation:
6 2/3 minutes
Step-by-step explanation:
Amare runs 1/10 mile in 2/3 minutes
Therefore his speed in miles per minutes clean be calculated as follows
= 1/10, the denominator here is 10
= 10 × 2/3
= 20/3
= 6 2/3 minutes
Answer:
Joseph's present age=3 yrs
David's present age=9 yrs
Step-by-step explanation:
Let Joseph's present age be x.
David's present age=3x
__________________
Ater 3 yrs,
Joseph's age=x+3
David's age=2(x+3)
Also, we can add 3 to David's present age to get age After 3 yrs. So, David's age after 3 yrs would also be 3x+3.
Now, balance them.
3x+3=2(x+3)
3x+3=2x+6
x=3
D"s prsent age=9
J's present age=3
Answer:
The sets of values that correctly completes the t-chart are:
7, -1, 7
Hence, option B is true.
Step-by-step explanation:
Given the equation
y = 2x² - 1
FOR x = -2
substitute x = -2 in the equation
y = 2x² - 1
y = 2(-2)² - 1
y = 8 - 1
y = 7
FOR x = 0
substitute x = 0 in the equation
y = 2x² - 1
y = 2(0)² - 1
y = -1
FOR x = 2
substitute x = 2 in the equation
y = 2x² - 1
y = 2(2)² - 1
y = 8 - 1
y = 7
Thus, the t-chart becomes:
x y
-2 7
0 -1
2 7
Thus, the sets of values that correctly completes the t-chart are:
7, -1, 7
Hence, option B is true.
