-1/2(x + 2) + 11/2 + x = 3
-1/2x - 1 + 11/2 + x = 3
1/2x + 9/2 = 3
1/2x = 3 - 9/2 = -3/2
x = -3/2 * 2 = -3
x = -3
644 divided by (8 x 8) (8x8) equals 61 so 644 divided 61 equals <span>10.557377049</span>
Answer:
130.356 g
Step-by-step explanation:
The problem tells you there is a proportional relationship, so set up a proportion and solve..
99.684 is to 11.7 as X is to 15.3
Written as a math equation like this...
99.684/11.7 = X/15.3
Now solve for X
130.356 = X (multiply both sides by 15, then simplify)
The area is 2x^2+x-10 (the last one) Hope this helps!
