3(x-3) = -2x + 31 what is the value of x?
Answer:
x= 8
Step-by-step explanation:
1. Expand.
3x-9=-2x+31
2. Add 9 to both sides.
3x=-2x+31+9
3. Simplify -2x+31+9 to -2x+40.
3x=-2x+40
4. Add 2x to both sides.
3x+2x=40
5. Simplify 3x+2x+5x.
5x=40
6. Divide both sides by 5.
x = 40/5
7. Simplify 40/5 to 8.
x=8

– 6 £ 2y < 5
y is an integer.
Write down all the possible values of y.
Answer:
all values less than 5.5
Step-by-step explanation:
Given the inequality expression – 6 + 2y < 5
We are to find all the possible values of x
-6 + 2 y < 5
Add 6 to both sides
-6 + 2y + 6 < 5 + 6
2y < 11
Divide both sides by 2
2y/2 < 11/2
y < 11/2
y < 5.5
hence the possible values of y are all values less than 5.5

. Center at (-4,-1), radius = 2
Consider we need to find the equation of the circle.
Given:
The Center at (-4,-1), radius = 2.
To find:
The equation of the circle.
Solution:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=-4, k=-1 and r=2, we get
[tex](x-(-4))^2+(y-(-1))^2=(2)^2[/tex]
[tex](x+4)^2+(y+1)^2=4[/tex]
Therefore, the equation of the circle is [tex](x+4)^2+(y+1)^2=4[/tex].

The length of the lunch area is 6 1/2 times it's width. If the width of the area is 10 6/13 feet, what is the length in simplest form?
Answer:the length of the Lunch area= 68 feet
Step-by-step explanation:
Since width of lunch area is given = 10 6/13 feet
and Length of the lunch area is 6 1/2 times it's width.= 6 1/2 x Width
Length = 6 1/2 x 10 6/13
changing to improper fraction foe easy solving
13/2 x 136/13
13 cancels out 13, we are left with
136/2 =68 feet

Deana made a scale drawing of her patio using a scale of 1/2 cm =1 foot what is the actual width, in feet, of deanas patio
Full question attached
Answer and explanation:
Given that 1/2cm= 1 foot
5cm= 2×5=10 feet
Length is twice the width, therefore real length of shape = 10×2=20 feet
Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet
Therefore Deana's Patio= 60 feet in real length
Answer:
60

Answer:
[tex]y = 17(3^{x} )[/tex]
Step-by-step explanation:
When x = 0, y = 17 So, [tex]17 = kb^{0} = k(1) = k[/tex]
Now, [tex]y = 17b^{x}[/tex]
When x = 5, y = 4131 So, [tex]4131 = 17b^{5}[/tex]
[tex]b^{5} = 4131/17 = 243 = 3^{5}[/tex]
b = 3
Therefore, [tex]y = 17(3^{x} )[/tex]

Write an equation that represents the line. Use exact numbers (i will mark you brainliest)✅
Answer:
y=4/5x-18/5
Step-by-step explanation:
there are multiple ways we can find the slope, let's use two points and the point slope form y=mx+b for this equation. we can find the slope by using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
in this case, we can use the two points (-3,-6), (2,-2)
y2=-2, y1=-6, x2=2, x1=-3
so, the equation is [tex]\frac{-2-(-6)}{2-(-3)}[/tex]
this reduces to 4/5
our slope is 4/5, so the equation for now is y=4/5x+b
let's use (2,-2) to find b. the y is -2, x is 2
-2=4/5(2)+b
-2=8/5+b, multiply both sides by 5:
-10=8+5b, subtract 8 from both sides
-18=5b, divide by 5
-18/5=b
our final equation is y=4/5x-18/5
What's the property of equality of r- 20 = 30

Addition Property: For all real numbers x,y, and z , if x=y , then x+z=y+z .
eflexive Property: For all real numbers x , x=x . A number equals itself.
Subtraction Property: For all real numbers x,y, and z , if x=y , then x−z=y−z .
so its subtraction property
