Answer: x < -3/2
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
Step 2: Divide both sides by -2.
Have a great day and I hope this is right!
The place value of the 4s in 244 reading from left to right are first 4 is in the tens place value so it represents 40 because 4x10=40. The second 4 is in the ones place and represents 4 because 4x1=4.
Answer:
a. -1
Step-by-step explanation:
Simply the equation: 3x+x+8=4
1st step: 4x+8=4
2nd step: 4x=4-8
3rd step: x=
4th step: x= -1
Answer: the number of hours that the Taylor's family spent using their is 15
the number of hours that the Simmon's family spent using their sprinkler is 20
Step-by-step explanation:
Let x represent the number of hours that the Taylor's family spent using their sprinkler last summer.
Let y represent the number of hours that the Simmon's family spent using their sprinkler last summer.
The families used their sprinklers for a combined total of 35 hours. This means that
x + y = 35
The water output rate for the taylor family's sprinkler was 40L per hour. The water output rate for the simmons family's sprinkler was 35L per hour. The total water output was 1300L. It means that
40x + 35y = 1300 - - - - - - - - - - -1
Substituting x =35 - y into equation 1, it becomes
40(35 - y) + 35y = 1300
1400 - 40y + 35y = 1300
- 40y + 35y = 1300 - 1400
- 5y = - 100
y = - 100/ - 5
y = 20
x =35 - y = 35 - 20
x = 15
