Answer:
(See bolded numbers)
<u>Factoring</u><u> -1 out of negative numbers</u><u>:</u>
11) (-6) • (3)= (-1 • 6) • 3= -1 • 6 • 3= -18
-6 is the negative number here and factoring out -1 from -6 will give us -1(6). In the second last step, multiply 6 and 3 together then multiply the product by -1.
-1(6 ×3)= -1(18)= -18
12) (-4) • (-8)= (-1 • 4) • (-1 • 8)= 1 • 4 • 8= 32
Multiplying 2 negative numbers will give us a positive number. The 3rd step is 1 as (-1)(-1)= 1.
13) (-9) • (-5)= (-1 • 9) • (-1 • 5)= 1 • 9 • 5= 45
14) (2) • (-8)= 2 • (-1 • 8)= -1 • 2 • 8= -16
Negative numbers are numbers with a negative sign and are numbers less than zero. Factoring -1 out of negative numbers will leave us with the positive number.
Let x be the number of child admission tickets sold:
Child's ticket = x
There is a total of 145 tickets sold:
Adult = 145 - x
Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8
Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87
Answer: Number of child's ticket = 87
Answer:
See explanation
Step-by-step explanation:
Maximum weight = 20 kg
Bag 1 = 3.5kg
Bag 2 = 15 kg
Bag 3 = 2kg
Bag 4 = 1.5kg
Total weight of bags = 22 kg
Excess weight of his luggage = Total weight of bags - Maximum weight
= 22 kg - 20 kg
= 2 kg
Express the excess weight as a percentage of his maximum weight allowed = excess weight / maximum weight × 100
= 2/20 × 100
= 0.1 × 100
= 10%
Express the excess weight as a percentage of his maximum weight allowed = 10%
