Answer:

its 25

Step-by-step explanation:

35+120 =155

180 (the sum of a triangle) - 155 = 25

missing triangle equals= 25

to check= add the 3 triangles together, if the sum adds up to 180 its correct.

125+35+25= 180 √

Answer:

136%

Step-by-step explanation:

Convert fraction (ratio) 68 / 50 Answer: 136%

Answer:

136%

Step-by-step explanation:

You just divide 68 by 50. Which will get you 1.2. The you multiply 100 by 1.36. So it becomes 136. Hope you understand :)

8)  Onaje is correct

9a) answers could be:  3(6y) or 4y + 6y + 8y  or 2(2y + 3y + 4y)

 b) all answers simplify to be 18y

Step-by-step explanation:

Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t

16t + 9t only equals 25t

Answer:

8. Onaje's expression is correct.

Step-by-step explanation:

The price, t, of the medium T-shirts can be represented as 16t, or 16 × t.

The price, t, of the large T-shirts can be represented as 9t, or 9 × t.

16t + 9t = (16 + 9) × t = 25t

Answer:

9. Part a: The expression could be 9y - 3y + 12y.

9. Part b: 9y - 3y = 6y

               6y + 12y = 18y

The distance between points is √65.

The length of the line that connects two points is the distance between them. The distance can be determined by subtracting the coordinates that are not the same if the two points are on the same horizontal or vertical line.

The distance formula is used in analytic geometry to determine the distance between two lines, the sum of the lengths of all sides of a polygon, the perimeter of polygons on a coordinate plane, the area of polygons, and a variety of other measurements.

Given coordinates

R(5, 7) and S(-2, 3)

to find the distance between

the formula of distance for coordinates is

d = [tex]\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1} )^{2} }[/tex]

here y₂ = 3, y₁ = 7

x₂ = -2, x₁ = 5

substitute value in equation we get

d = [tex]\sqrt{({3 - 7 )^{2} + (-2 - 5 )^{2} }[/tex]

d = [tex]\sqrt{({-4 )^{2} + (-7 )^{2} }[/tex]

d = √(16 + 49)

d = √65

Hence the distance is √65.

Answer:

e.

Step-by-step explanation:

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).

Answer:

the required equation to represent the total cost with respect to every hour will be

=》y = 42x + 65

Step-by-step explanation:

total cost (y) = charge to make a house call + additional charge for every our

so, total additional charge for x hours

= 42 × x = 42x

hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )

Answer:

x > -1

Step-by-step explanation:

-3x + 15 < 18

Subtract 15 from each side

-3x + 15-15 < 18-15

-3x < 3

Divide each side by -3, remembering to flip the inequality

-3x/-3 > 3/-3

x > -1
