b.Do you need to multiply any of the equations by a constant? If so, which equation and what is the constant?
Answer:
Step-by-step explanation:
well you have girls as x and boys as y so then its x+y = 45 and x+8 = y so then you can substitute to get 2x +8 =45 which i believe is a system but I'm not sure. then you solve to get a half… thats not right but i think i hav the system part sorry
121 gallons of gas
25 gallons of gas
115 gallons of gas
Answer:
Step-by-step explanation:
To calculate how many gallons the van needs to travel 550 miles you should multiply the number of miles by the relationship between the number of gallons of gas it needs to travel 220 miles, (it is important to put the quantity in miles on the denominator) as follows:
Therefore the van needs 25 gallons of gas to travel 550 miles
Answer:
$10.55
Step-by-step explanation:
First, add 5% of 9 to nine.
5% of 9 :.45
.45+9=9.45
So, then, subtract 9.45 from 20, which leads to 10.55 as your answer

Answer:
First, let's convert the mixed numbers into improper fractions:
3 3/10 = (3 * 10 + 3)/10 = 33/10
1 4/7 = (1 * 7 + 4)/7 = 11/7
Now, we can divide the two fractions:
33/10 ÷ 11/7
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 11/7 is 7/11.
So, the division becomes:
33/10 * 7/11
Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
(33 * 7) / (10 * 11) = 231/110
Finally, simplify the fraction, if possible. In this case, we can divide both the numerator and denominator by their greatest common divisor, which is 11:
231/110 = (231 ÷ 11)/(110 ÷ 11) = 21/10
Therefore, 3 3/10 divided by 1 4/7 is equal to 21/10.
