Answer: 20× + 10 < 90
Step-by-step explanation:
Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
What is inequality?Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.
Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
Let's assume Blake has to mow x lawns to have at least $90 saved.
Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.
Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:
20 + 10x ≥ 90
Subtracting 20 from both sides:
10x ≥ 70
Dividing both sides by 10:
x ≥ 7
Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7

Kyle used 15 centimeters of tape to wrap 3 presents. How much tape will Kyle need in all if he has to wrap 5 presents? Assume the relationship is directly proportional.
?centimeters
Answer:
25
Step-by-step explanation:
Point-slope form
Complete the point-slope equation of the line through (-4, 8) and (4,4).
Use exact numbers.
WHOEVER ANSWERS RIGHT GETS BRAINIST
There are actually two correct answers, one of them is y-4=-0.5(x-4)
First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.

Answer:
If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2
Finally, simplify the expression.

-c+1 > 2 now this one
-c + 1 > 2
-c > 2-1 Move 1 to subtract.
-c > 1
c < -1 When the coefficient is negative, moving the negative to another side as changing the sign of Inequality to opposite.
Thus, the answer is c < -1

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55

find the midpoint of joining 4 - 5 and 8 - 3
Answer:
(6, - 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (8, - 3) , then
midpoint = ([tex]\frac{4+8}{2}[/tex], [tex]\frac{-5-3}{2}[/tex] ) = ([tex]\frac{12}{2}[/tex], [tex]\frac{-8}{2}[/tex] ) = (6, - 4 )
