Total raised: 264
She raised 30 plus 1.80x (x being the number of minutes).
Equation: 264=1.8x+30
To solve for x, you need to isolate x. First, subtract 30 from both sides.
234=1.8x
Now, divide both sides by 1.8.
130=x

I hope this helps :)
I think answer is 9.3 after it’s rounded
use the formula a^2 +b^2=c^2
No Solution (i cant see the picture you attached but i can explain why.)
cos^-1(sqrt2/2)=0 is false
Answer:
x<8
Step-by-step explanation:
Open parenthesis first:
3x-6<18
Put all like terms on one side:
3x<18+6
3x<24
Simplify:
3x<24 -----> Divide both sides by 3 to cancel out the 3 in 3x.
x<8

Answer:
27 inches
Step-by-step explanation:
Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches
Perimeter of rectangle = 2(L + W)
L = 11 in.
W = 7 in.
Perimeter of rectangle = 2(11 + 7) = 36 in.
Let perimeter of the triangle be represented by x
Therefore:
36 + x = 63
Subtract 36 from each side
x = 63 - 36
x = 27
Perimeter of triangle = 27 inches
