Step-by-step explanation:
the formula can be;
X+9x=10
10x=10X=10/10=1
X=1+9(1)=1+9=10 Answer
Hello there!
28 recipes .......> 100%
15 recipes .......> x%
Cross multiply
28x = 15*100
28x = 1500
x= 1500/28
x ≈ 53.5%
She makes 53.5% of the recipes.
I hope that helps!
Answer:
4,055
Step-by-step explanation:
The cosine repeats itself every 360 degrees, and it mirrors at 0 and 180 degrees. It inverts around 90 and 270.
So without using a calculator, you can tell that:
cos(520)=cos(520-360)=cos(160)
cos(160) = cos(180-20) = cos(180+20) = cos(200)
cos(160) is NOT equal to cos(20), it would be -cos(20).
cos(160) = -cos(20) = -cos(-20)
So C is the only one unequal.
Answer:
y=-x+5+-x-5
Step-by-step explanation:
In absolute value, make the content inside the bars the opposite of what it was before. X is less than -5, but the number it is is still unknown, meaning it should still be written as x.
