Solve the inequality:
7x < 3 + 7(x – 1)
Answer:
7=7
Step-by-step explanation:
Simplify
7+37+3 to 1010.
7x=107x=10
Divide both sides by:
77 x={10}{7}x= 7 10
Let x=10/7x= 7 10/7 -3=77× 7 10
−3=7
Cancel 7:
10-3=710−3=7
Simplify
10-310−3 to 77.

The elevations of four points above sea level there are -47 ft, -20 ft,-8 ft, and -18 ft. The elevation of the point closest to sea lvl (level) is _____ ft, and the elevation of the point farthest from sea lvl is _____ ft. (FILL IN THE BLANKS PLS HELP)
Answer:
The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Step-by-step explanation:
Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.
–42ft, –20ft, –18ft, –8ft.
From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Solve for x and then solve for y.
Answer:
y = 62
Step-by-step explanation:
Since we need to solve for x first, we'll solve the left triangle first. A triangle equals 180 degrees, so with in mind:
x + 7 + 3x - 18 + x - 9 = 180
add like terms
5x - 20 = 180
add 20 to both sides
5x = 200
divide by 5
x = 40
Now we have x, input it into the equations for the second triangles:
x + 21 + x + 17 + y = 180
40 + 21 + 40 + 17 + y = 180
add/simplify
118 + y = 180
subtract 118 from both sides
y = 62
Answer:
x = 40° ; y = 62°
Step-by-step explanation:
The figure consists of 2 triangles. According to Angle sum property in a triangle , sum of measure of all the angles of a traingle is equal to 180° .
So ,
[tex](3x - 18) + (x + 7) + (x - 9) = 180[/tex]
[tex] = > 5x - 20 = 180[/tex]
[tex] = > 5x = 180 + 20 = 200[/tex]
[tex] = > x = \frac{200}{5} = 40[/tex]
Now using the angle sum property in another triangle ,
[tex](x + 21) + (x + 17) + y = 180[/tex]
[tex] = > y + (40 + 21) + (40 + 17) = 180[/tex]
[tex] = > y + 61 + 57 = 180[/tex]
[tex] = > y + 118 = 180[/tex]
[tex] = > y = 180 - 118 = 62[/tex]

I have the same test
plzzzzz help me i need help on this guys? i dont know if its correct!
Answer:
Haha no. It obviously equals fish.
Seriously though, 1+1 = 2.
What is the answer.........
Answer:
1 is correct
2 is correct
3 is incorrect
4 is incorrect
5 is correct
Step-by-step explanation:
1 is correct because the statue lies the same distance from both entrances.
2 is correct because B is also the same distance from both entrances.
3 is the opposite of 2, saying that B is not equal distance from both entrances, making it false.
4 is incorrect because a is closer to the upper entrance.
5 is correct because it is basically the same question as 2, saying b is the same distance from both entrances.
which number line shows the solution of 5x - 25 greater than -15
Answer:
you need to add number lines, but if you want the equation to be written and solved, then...
Step-by-step explanation:
5x - 25 > -15
+25 +25
5x > 10
divide both sides by 5
x > 2

Which linear inequality is represented by the graph?
Answer:
The answer would be the last option. y<2/3x-1
Step-by-step explanation:
The slope is 2/3 and the line crosses the y axis at -1. Since the shaded part is below the line it would make the sign less than (<)
Write an explicit formula for an, the nth term of the sequence 33, 28, 23, ....
Answer:
I believe it's an = 33 - 5(n - 1) or 38 - 5n they both should work
Step-by-step explanation:
I'm think that explicit formulas are like an = a1 +d(n - 1) and just replace the Variables with the correct numbers

Please help me with this
Answer:
The length= 16cm
The width= 6cm
The two long sides are 8cm both so 8 + 8 = 16
And the two short sides are 3cm both so 3 + 3 = 6
So your length should be 16cm and your width 6cm

Answer:
y=10 when x=7
Step-by-step explanation:
y=2x-4
y=10
Substitute y with "10": 10=2x-4
Add 4 on both sides: 14=2x
x=7
Answer:
substitute 10 for y in the equation y=2x-4
10=2x-4
2x=10+4
2x=6
divide both side by 2
x=3

Step-by-step explanation: 4+4+1+1=10The perimeter of a rectangle is the sum total length of all of its sides.[1] A rectangle is defined as a quadrilateral, or a geometric shape with four sides. In a rectangle, both sets of opposite sides are congruent, meaning that they are the same length.[2] While not all rectangles are squares, all squares can be considered rectangles, and a compound shape may be composed of rectangles.[3]
