Two more than the sum of a number and three is more than fifteen. (Write the equation and solve it)
X + 3 +2 > 15
Subtract 2 from both sides
X + 3 > 13
Subtract 3 from both sides ;)
X > 10
Answer:10
Step-by-step explanation:
X + 3 +2 > 15 would be the equation
First we Subtract 2 from both sides,which gives us this.
X + 3 > 13
Then we Subtract 3 from both sides
which gives us an answer of
X > 10
which we can also write as 10

3:combine like terms (the -2/3x was combined with +1/3x)
4:addition property of equality (the -8 was added to both sides of the equation)
5:transitive property (divided both sides by -1/3 to get x alone)
6:symmetric property (rewrote the answer)

solve the equation -2y + 6 =-12
Answer:
[tex] - 2y + 6 = - 12 \\ - 2y = - 12 - 6 \\ - 2y = - 18 \\ y = \frac{ - 18}{ - 2} \\ y = 9[/tex]
Answer:
-2y + 6 = -12 (subtract 6 from both sides to get the y-term alone)
-2y = -18 (divide both sides by -2 to get y alone)
y = 9 (this is your answer)
Liz earns a salary of $2,300 per month, plus a commission 5% of her sales. She wants to earn at least $2,500 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal.
Answer:
she needs to earn at least $200 more to equal $2,700, so
200=x($amount of needed sales) * .06
200/.06=x
$3,333=x is sales needed to meet goal
variable is $ amount of sales needed to earn $2,700 this month.
Commission rate as decimal=.06
Inequality that represents is...
x> or = $3,333

Step-by-step explanation:
Answer:
Step-by-step explanation:
3. slope of CB = rise/run = 5/12 BF = 5 CF = 12
BF ⊥ DF
DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4
4. f(x) = 2x² - 5x -3 vertex : A (h,k) for f(x) = ax² + bx +c
h = - b/2a = - (-5 / 4) = 5/4
f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8
A (5/4 , - 49/8) i.e. (1.25 , - 6.13)
negative root: 2x² - 5x -3 = (2x+1) (x- 3) x = - 1/2 y = 0
B (- 1/2 , 0)
x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375
At the school carnival, the sixth graders are making directional arrows, as shown below.
A polygon shaped like an arrow is shown. The total height of the arrow head and the arrow tail is 7 inches. The base of the arrow tail is 4 inches. The width of the arrow is 6 inches, and the height of the tail of the arrow is 5 inches.
Each arrow is to be painted red. How much area needs to be painted for 1 arrow?
To make it easier heres the picture!:
Answer:
32 Inches
Step-by-step explanation:
First, split arrow into triangle and rectangle
----------------------------------------------------------------
Rectangle:
Area=5x4
=20
--------------------------------------------------------------
Triangle:
Area=6x2
=12
-----------------------------------------------------------------
Add both shapes areas together
to find total
------------------------------------------------------------------
Total=32 Inches
The solution is : 26 sq.Inches area needs to be painted for 1 arrow.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
First, split arrow into triangle and rectangle
Rectangle:
Area=5x4
=20
Triangle:
Area=6x2/2
=6
Add both shapes areas together
to find total
Total=20 + 6 sq.Inches
= 26 sq.in.
Hence, The solution is : 26 sq.Inches area needs to be painted for 1 arrow.
