The answer is B)
x2+2x−3=0
Factor left side of equation.
(x−1)(x+3)=0
Set factors equal to 0.
x−1=0 or x+3=0
x=1
or
x=−3
I believe that it is 45 degrees. i could be wrong, so make sure to check!
Here is the equation: x+(x+20) = 120
Since you can't combine anything yet, its x+x+20=120
You need to get x by itself
Minus 20 from both sides
Its x+x=100 now
Combine the x's which is now 2x
Now divide 100 by 2 which is 50
x=50
---------------
Lets check:
50+(50+20)=120
Now combine the numbers in the parentheses
Its now 50+70=120
50+70=120 and 70-50=20
As you can see, he ran 50 minutes the first day and 70 minutes the second day
Hello!
If Barbara mixes 54 ounces of granola and 36 ounces of raisins, the overall mixture will equal 90 ounces. In order to find the amount of servings that Barbara makes, we must divide the total number by the other number given - 6.
Because Barbara wants to divide the mixture into 6 ounce servings, we will divide 90 by 6.
90/6=15
The answer to your question is "Barbara made 15 6-ounce servings."
I hope this helps you! Have a great day!
