Answer:
The ratio is;
3/7 : 1
Step-by-step explanation:
Here, we want to express the given ratio in the form n:1 where n is a fully simplified fraction
Mathematically, we have this by dividing both numbers by 14
That would be ;
6/14 : 14/14
= 3/7 : 1
Answer:
B. x = -4
E. x = 10
Step-by-step explanation:
Answer:
Last choice that shows points on +4 and -4 is the correct graph.
Step-by-step explanation:
We have been given equation 
. Now we need to find out which of the given number lines shows the corret solution set for .
We know that 
can be broken into two parts as:
and 
Same way we can break into two parts as:
and 
Hence last choice that shows points on +4 and -4 is the correct graph.
You're mixing water and flour, following the rule that for each 4.5 cup of flour you add 10 cups of water.
Note that 10:4.5 is equivalent to 20/9.
Answer:
x = -12 x = -5
Step-by-step explanation:
-7x-60=x^2+10x
Add 7x to each side
-60=x^2+10x+7x
-60=x^2+17x
Add 60 to each side
0 = x^2+17x+60
Factor
What 2 numbers multiply to 60 and add to 17
12*5 = 60
12+5 = 17
0 = (x+12) (x+5)
Using the zero product property
x+12 = 0 x+5 =0
x = -12 x = -5
