Solve (x + 1 < 5) ∩ (x - 4 > -3).
Answers
Answer:
(1, 4)
Step-by-step explanation:
(x + 1 < 5) is solved by subtracting 1 from both sides of this inequality:
x < 4.
(x - 4 > -3) is solved by adding 4 to both sides: x > 1.
The solution of (x + 1 < 5) ∩ (x - 4 > -3) is thus (1, 4).

Yes, there are enough computers 992 to be distributed to 90 schools.
What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a county has 90 schools. The county received 992 new computers.
The required computers for 90 schools will be calculated as,
Computer required = 90 x 11
Computer required = 990
Available compters = 992
Remaining = 992 - 990 = 2 computers
Therefore, there are enough computers 992 to be distributed to 90 schools.

Now we need to find the rate in order you to paint one wall.
1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08
So the rate per one wall is 1.08 hours.

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
Answer:
D
Step-by-step explanation:
y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)
That means the equation is y = 50x + 25

Percentage of children from an after school that went to the martinee = 25%
Let us assume the number of children in the club = x
Then
25% * x = 40
(25x/100) = 40
x/4 = 40
x = 40 * 4
= 160
So the total number of children in the club is 160. I hope the procedure is clear enough for you to understand. you can always use this method for solving similar problems without requiring any help from outside.

The answer is 1.
4x + 3x - 1 = 6
7x - 1 = 6 -Add the like terms
7x - 1 + 1 = 6 + 1 -Add 1 to both sides to 7x by itself
7x = 7
7x / 7 = 7 / 7 -Divide both sides by 7
x = 1
Hope I helped!
To put this into words, the equation is saying that one less than 4x + 3x is equal to 6.
First simplify by combining like terms. We see there is a 4x and 3x, which means that they are compatible with each other. The equation will then look like . If one less than 7x is 6, then this can also mean one more than 6 is equal to 7x. So add 1 to both sides:
--> , which means that x = 1.
Checking your work:
Now that we know the value of x, substitute that for x in the equation like this:
-->
--->
So you know it's true that x = 1. Hope this was helpful.
