Answer:
x = 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-5*x+15-(35-10*x)=0
Pull out like factors :
5x - 20 = 5 • (x - 4)
_________________________________________
Solve : 5 = 0
This equation has no solution.
A a non-zero constant never equals zero.
_________________________________________
Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
Answer:
Rounded to the nearest integer, the test had 18 problems in all.
Step-by-step explanation:
Given that a student missed 10 problems on an English test and received a grade of 44%, if all the problems were of equal value, to determine how many problems were on the test the following calculation must be performed:
100 - 44 = 56
56 = 10
100 = X
100 x 10/56 = X
1,000 / 56 = X
17.85 = X
Thus, rounded to the nearest integer, the test had 18 problems in all.
Simon has $45.37
Simone savings from allowance= $15.45
Amount Simone had in piggy bank = $7.37
Left over from birthday = $22.55
Total amount of money that Simone now has = $15.45 + $7.37 + $22.55
Total amount of money that Simone now has = $45.37
