Answer:
y=(x^2 -2x-3)/3
Step-by-step explanation:
f(x)= √3x+4 -1
x=√3y+4 -1
(x+1)^2=(√3y+4)^2
3y+4=x^2 +2x+1
3y=x^2 +2x-3
y=(x^2 +2x-3)/3
Answer:
a. 35 Kilometres.
b. 60 litres.
c. 8150 sweets.
Step-by-step explanation:
<u>Given the following data;</u>
- Distance traveled = 770 km
- Number of days = 22 days
a. To find how many kilometres he traveled in one day;
770 km = 22 days
X km = 1 day
Cross-multiplying, we have;
22X = 770
X = 770/22
<em>X = 35 Kilometres.</em>
b. To find how many litres he would need to go 840 km;
1 litre = 14 kilometres
X litres = 840
Cross-multiplying, we have;
14X = 840
X = 840/14
<em>X = 60 litres.</em>
c. To find how many sweets are there in his car;
Number of sweet box, Ns = 326 boxes
Number of sweets in each box, Sw = 25 sweets
Total number of sweets = Ns * Sw
Total number of sweets = 326 * 25
<em>Total number of sweets = 8150 sweets.</em>
Answer:
2695 miles
Step-by-step explanation:
Answer:
5-15= -20 20+12 = 8 yards
Step-by-step explanation:
Expression: 5-15+12=8
Sum: 8 yards
Its 8 yards because they lose a total of 20 yards then gains 12 yards so you just have to subtract 20 and 8 = 12 yards
Answer:
31 pounds
Step-by-step explanation:
From the information given, you can write the following formula to calculate the total cost of sending gifts:
Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds
Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:
28.85=2.50+0.85x
28.85-2.50=0.85x
26.35=0.85x
x=26.35/0.85
x=31
According to this, the answer is that the gifts weighed 31 pounds.
