x is approximately 15.038 or 15 days
Question 3
$3.41
Question 4
31.1
Step-by-step explanation:
Question 2
5.2 km/1 day =78.2 km/x days
Multiply both sides by x
5.2x=78.2
divide by 5.2
x is approximately 15.038
or 15 days
Question 3
350-(262.94+83.65)
$3.41
Question 4
22(1.3)+2.5
31.1 m
Answer: 15.28
Step-by-step explanation: I just added them together
The algebraic expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)
<em><u>Solution:</u></em>
Given the statement:
Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen
Let us first understand the given statement,
Let the number be "x"
" sum of a number and four" means x + 4
"Three sets of a sum of a number and four" translated to 3(x + 4)
"sum of seven times the same number and thirteen" means 7x + 13
<em><u>Thus the algebraic expression for given statement is:</u></em>
<em><u>Using distributive property in above expression</u></em>
Therefore,
<em><u>Combine the like terms</u></em>
Thus the required expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)
2.95 is the cost of each fish sandwich because 14.30 minus 2.50 is 11.80 and 11.80 divided by 4 is 2.95.
Answer:
Screen 1: 200, Screen 2: 125 , Screen 3: 175
Step-by-step explanation:
Screen 1
Multiply 40% and 500
Convert 40% to a decimal
40/100=0.40
500*0.40
200
Screen 2
Multiply 25% and 500
Convert 25% to a decimal
25/100=0.25
500*0.25
125
Screen 3
Subtract the amount of people that went to screens 1 and 2 from the total
500-200-125
175
So, Screen 1 had 200 visitors, 2 had 125 and 3 had 175
Hope this helps! :)
