For the first question, x = 4
Answer:
2,196; 549; 131.76; 8; 175.68; 1339.56
Step-by-step explanation:
2,196 is the biggest number, so use that as the first number.
.25x2196=549
.06x2196=131.76
.08x2196=175.68
2196-(549+131.76+175.68)=1339.56
Answer:
28 minutes
3.5 x 8 = 28
Step-by-step explanation:
Feeding the whole school (8/8) would take 8 times as long as feeding 1/8 of the school.
3 1/2 can become 3.5 if that's easier for you to work with.
Feeding 1/8 of the school is 3.5 x 1 = 3.5
Feeding 2/8 of the school is 3.5 x 2 = 7
Feeding 8/8 of the school is 3.5 x 8 = 28
It takes 28 minutes to feed the whole school (8/8)
Answer:
453.6 grams
Step-by-step explanation:
40 x 5.67 = 226.8
226.8 x 2 = 453.6
Answer:
x = 28
Step-by-step explanation:
Given that lines AB and CD are straight lines that intersects at O, it follows that the pair of opposite vertical angles formed are congruent.
Thus,
<AOD = <BOC
<AOD = 152°
<BOC = 3x + x + (x + 12) (angle addition postulate)
<BOC = 5x + 12
Since <AOD = <BOC, therefore,
152° = 5x + 12 (substitution)
152 - 12 = 5x (subtraction property of equality)
140 = 5x
140/5 = x (division property of equality)
28 = x
x = 28
