0.5 cups of cheese
Amy: 1.6 divided by 8 = 0.2 cups of cheese per serving
Sarah: 2.5 divided by 10 = 0.25 cups of cheese per serving
0.25 - 0.2 = 0.5
Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
Answer:
131
Step-by-step explanation:
x=6(25)-19
x=150-19
x=131
All you do is multiply 22 times 8 which is 176 then you multiply 8*4
You mean "completing the square," don't you? ;)
<span>(x+7)(x-9)=25 can be expanded: x^2 - 9x + 7x - 63 + 25, which becomes
x^2 -2x = 38.
Let's now complete the square:
x^2 - 2x + (1)^2 - (1)^2 = 38, or x^2 - 2x + 1 = 39
Rewrite that as (x-1)^2 = 39
Take the sqrt of both sides: x-1 = plus or minus sqrt(39)
Write the roots: x = 1+sqrt(39) and x = 1 = sqrt(39) (answers)</span>
