Answer:

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

Answer:

Step-by-step explanation:

16 units 40 units 48 units 64 units.

Answer:

64 units

Step-by-step explanation:

Given M lies on LN, so LN = LM + MN --------------(1)

LN = 12x + 16

LM = 10x + 8

MN = 5x - 4

Substituting the values in equation 1, we get:

12x + 16 = (10x + 8) + (5x - 4)

12x + 16 = 15x + 4

15x - 12x = 16 -4

3x=12

Therefore x=4

LN= 12(4) + 16 = 64 units

Answer:

Kai will walk 8 miles

Step-by-step explanation:

Have a gr8 day!

Given:

A caterpillar moves across the grass at a rate of [tex]4\dfrac{2}{3}[/tex] feet every 7 minutes.

To find:

The rate of moving caterpillar in feet per minute.

Solution:

We have,

Distance covered by caterpillar is 7 minutes = [tex]4\dfrac{2}{3}[/tex] feet

Distance covered by caterpillar is 1 minutes = [tex]\dfrac{4\dfrac{2}{3}}{7}[/tex] feet

                                                                        = [tex]\dfrac{\dfrac{4(3)+2}{3}}{7}[/tex] feet

                                                                        = [tex]\dfrac{14}{3\times 7}[/tex] feet

                                                                        = [tex]\dfrac{2}{3}[/tex] feet

Therefore, caterpillar move [tex]\dfrac{2}{3}[/tex] feet per minute.

Answer:

Step-by-step explanation:

kinda self explanatory

dividing it, adding it, and subtracting it wouldnt make sense for the equation youre trying to solve.

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

Solution

here, length= 5cm

breath= ?

Perimeter= 86 cm

By the question,

Perimeter (P) = l×b = 86 cm

or, 5cm × b= 86 cm

or, b = 86÷ 5

or, b= 17.2 cm

Answer:

The co-ordinates of B are ( 7,1)

Step-by-step explanation:

Step(i):-

Given that 'M' is the midpoint of AB

Given co-ordinate points are A(-1,5) and midpoint M(3,3)

we know that the midpoint formula

[tex]midpoint = (\frac{x_{1} +x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]

[tex](3,3) = (\frac{-1+x_{2} }{2} ,\frac{5+y_{2} }{2} )[/tex]

Step(ii):-

Equating

        [tex]3 = \frac{-1+x_{2} }{2}[/tex]      and   [tex]\frac{5+y_{2} }{2} = 3[/tex]

cross multiplication, we get

     6 = -1 + x₂    and  6 = 5 +y₂

     x₂ = 6+1        and y₂ = 6-5

    x₂  = 7         and    y₂ = 1

Final answer:-

The co-ordinates of B are ( 7,1)

Answer:

1 and 2 are rectagles and 3 is not

Step-by-step explanation:

ordered pair (1, 5) is a solution to the equation 6x-y=1

Two or more expressions with an Equal sign is called as Equation.

The given equation is 6x-y=1

We need to find an  ordered pair (x, y) that is a solution to the equation.

any values of x and y when we substitute in the given equation should give the result 1.

Those values are the solutions of equation

Let x=1 and y=5

6(1)-5=1

1=1

Hence, ordered pair (1, 5) is a solution to the equation 6x-y=1

Answer:

x = 23

Step-by-step explanation:

the angles in a triangle add up to 180

the square means 90

90 + 67 + x = 180

157 + x = 180

157 - 157 + x = 180 - 157

x = 180 - 157

x = 23

Answer:

Slope= -5/4

Y-intercept= 1

Step-by-step explanation:

First put into slope-intercept form, which would get y= -5/4x+1.

Then identify what's what, with the formula y=mx+b, where m is the slope and b is the y intercept. Using that you can see that -5/4 is the slope and 1 is the y.
