Answer: 4 ≥ x
Step-by-step explanation:
We want to solve the inequality
2*x + 5 ≥ 3*x + 1
We can solve it in the same way as a normal equation, we need to isolate x in one side of the equation.
I will isolate x in the right side.
2*x + 5 ≥ 3*x + 1
First, we subtract 2*x in both sides:
(2*x + 5) - 2*x ≥ 3*x + 1 - 2*x
5 ≥ x + 1
Now we subtract 1 in both sides:
5 - 1 ≥ x + 1 - 1
4 ≥ x

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC. calculate area of triangle ABC.
Answer:
solution :
in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.
now ,
in rt angle tirangle ADC,
angleACD=45 degree, angle DAC=45 degree now,
in triangle ABD,
angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)
angle BAD+75+30=180
angle BAD=180-165 therefore,angle BAD=15
angle BAC =15+45=60
Area of triangle ABC=1/2×AB×AC×SIN 60
=1/2×10.2×14×√3/2
=61.83cm³ ans
Patty counted 250 chocolate chips on a tray of cookies. The actual amount of chocolate chips on the tray were 265. What is the percent error? *
Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100
percent error= 265-250/250*100
percent error=15/250*100
percent error=0.06*100
percent error=6%

Using the figure above, what are the measures of the 3 angles in triangle DEF? PLS HURRY! THANKS
Answer:
F= 34 degrees (alternate angles are equal)
To find D
we first have to find the angles at AB
B =180- 165 (sum of angles on a straight line = 180°)
therefore B = 15°(we'll use this to find the angle at E)
A=34 (from the diagram)
so,
D = 180- (15 + 34) [sum of angles in a triangle = 180°]
D = 131°
E=15° (alternate angles are equal )

How do you solve -2+x=-x+2
Answer:
x=2
Step-by-step explanation:
-2 + x = -x + 2
Isolate the variable
2x = 4
Simplify
x = 2
Answer:
x = 2
Step-by-step explanation:
you want to move the variables to one side, the numbers to the other side.
x = -x+4
then you move the other x
2x = 4
x = 2

Latest Releases Depot rents DVD/Blue ray for $3.00 each and has no membership fee. Video for You rents DVD/Blue rays for $2 each but has a membership fee of $15.
Answer:
15 rentals
Step-by-step explanation:
Latest Releases Depot
rent = $3 per DVD
membership= free
let the number of DVD be x
let the expression for the total be
y= 3x----------------1
Video for You
rent= $2 per DVD
membership= $15
let the number of DVD be x
let the expression for the total be
y= 15+2x----------------2
equate 1 and 2
3x=15+2x
collect like terms
3x-2x=15
x= 15
Hence the number of DVDs needed for the two rentals to have the same amount is at least 15 rentals

Suppose the side length of square A is 6 inches, and the side length of square B is 9 inches. What is the area of square C if the three squares create a right triangle? A 15 in B 54 in? C 108 in? D 117 in
Answer:
D.117 square in
Step-by-step explanation:
We are given that
Side length of square A=6 in
Side length of square B=9 in
We have to find the area of square C if the tree squares create a right triangle.
By using Pythagoras theorem
[tex](hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2[/tex]
Side of square C
[tex](Hypotenuse)^2=6^2+9^2[/tex]
[tex](Hypotenuse)^2=117[/tex]
[tex]Hypotenuse=\sqrt{117}[/tex]
Now,
The area of square C=[tex](side)^2[/tex]
The area of square C=[tex](\sqrt{117})^2=117 in^2[/tex]
Option D is true.

2y – 9x = 4
......................
Answer:
y=9/2x+2
Step-by-step explanation:
Answer:
x=2/9y + -4/9
Step-by-step explanation:
Solve for x:
2y−9x=4
Add -2y to both sides:
−9x+2y+−2y=4+−2y
−9x=−2y+4
Divide both sides by -9:
−9x /−9 =−2y+4 /-9
Then your answer is:
x= 2 /9 y+ −4/ 9

Answer:
slope: -3y-intercept: -5equation: y = -3x -5Step-by-step explanation:
a) The slope (m) is given: -3.
__
b) The y-intercept (b) can be found from the slope (m) and the given point (h, k) using the relation ...
b = k -mh
b = 4 -(-3)(-3) = 4 -9
b = -5 . . . y-intercept
__
c) Of course, the slope-intercept equation is ...
y = mx +b
y = -3x -5
