Answer:

Priyah = 15

Amirah = 19

Shirley = 13

Step-by-step explanation:

Let A represents Amirah, P Priyah and S, Shirley.

So, we have:

[tex]A = 4 + P[/tex] --- 4 years older

[tex]S = P - 2[/tex] --- 2 years younger

[tex]A + P + S = 47[/tex]

Required

Find their ages

Substitute 4 + P for A and P - 2 for S in [tex]A + P + S = 47[/tex]

[tex]4 + P + P + P - 2 = 47[/tex]

[tex]4 + 3P - 2 = 47[/tex]

Collect Like Terms

[tex]3P = 47 - 4+ 2[/tex]

[tex]3P = 45[/tex]

Divide both sides by 3

[tex]P = \frac{45}{3}[/tex]

[tex]P = 15[/tex]

Substitute 15 for P in [tex]A = 4 + P[/tex] and [tex]S = P - 2[/tex]

[tex]A = 4 + 15[/tex]

[tex]A = 19[/tex]

[tex]S = 15 - 2[/tex]

[tex]S = 13[/tex]

Answer:

b<-10

Step-by-step explanation:

Inequality: -b-2>8

Step 1: Add 2 to both sides

-b-2+2>8+2

-b>10

Step 2: Divide both sides by -1

-b > 10

Answer:

z = 22

Step-by-step explanation:

Since this is a rhombus, we know that parallel sides are equal in length and that the angles should add to 360 degrees. The opposing angles, therefore, are also equal in size. So, you can find the answer by setting the two angles to each other.

3z = z + 44

2z = 44

z = 22

Answer:

z=22

Step-by-step explanation:

3z = z + 44

3z - z = 2z

2z = 44

z = 22

Answer:

Its the first choice. Width:9 Length:13

Step-by-step explanation:

If the length is 4 meter more than the width than that means whatever the width is you must add 4 to it, in this case the width is 9 so add 4 to it which equals 13. If the length matches your answer it is the correct choice.

The area of a rectangle is the product of its dimensions. The dimension of the rectangle is: [tex]Length = 13m[/tex] and [tex]Width = 9m[/tex]

Given that:

[tex]L =4 + W[/tex]

[tex]Area = 117[/tex]

The area of a rectangle is:

[tex]Area = L \times W[/tex]

So, we have:

[tex]L \times W= 117[/tex]

Substitute [tex]L =4 + W[/tex]

[tex](4 + W) \times W = 117[/tex]

Expand

[tex]4W + W^2 = 117[/tex]

Rewrite as:

[tex]W^2 + 4W- 117 = 0[/tex]

Expand

[tex]W^2 + 13W - 9W - 117 = 0[/tex]

Factorize

[tex]W(W + 13) - 9(W + 13) = 0[/tex]

Factor out W + 13

[tex](W - 9)(W + 13) = 0[/tex]

Solve for W

[tex]W = 9[/tex] or [tex]W = -13[/tex]

The dimension cannot be negative.

So:

[tex]W = 9[/tex]

Recall that:

[tex]L =4 + W[/tex]

[tex]L = 4 + 9[/tex]

[tex]L = 13[/tex]

So, the dimension of the rectangle is:

[tex]Length = 13m[/tex]

[tex]Width = 9m[/tex]

Step-by-step explanation:

Answer:

The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.

We know that the perimeter of a circle of radius R is equal to:

P = 2*pi*R

where pi = 3.14

Then if the radius of the patio is 70ft, the perimeter of the patio will be:

P = 2*3.14*70ft = 439.6 ft

Then he needs 439.6 ft of fencing to enclose the patio.

Hi there!

[tex]\large\boxed{(3) \text{ } 4x^{3} - x^{2} + 3x + 13}[/tex]

Given:

A = 6x³ - x² + 4x + 8

B = 2x³ + x - 5

Find A - B by subtracting the two equations. Subtract like-terms:

6x³ - x² + 4x + 8 - (2x³ + x - 5)

Simplify:

6x³ - x² + 4x + 8 - 2x³ - x + 5 =

4x³ - x² + 3x + 13. The correct choice is 3.

12 inches

if the length = x,

P = 150 inches

=2 { ( 5x + 3 ) + x }

=10x + 6 + 2x

=12x + 6

Therefore 12x + 6 = 150

12x = 150 - 6

12x = 144

x = 12

Answer:

b + g = 25

b = g + 3

Step-by-step explanation:

Let b = number of boys.

Let g = number of girls.

"Mrs. Smith has a total of 25 kids in her class."

b + g = 25

"There are 3 more boys than there are girls."

b = g + 3

The system of equations is:

b + g = 25

b = g + 3

Answer:

Option B

Step-by-step explanation:

We know that

[tex] \sin( \alpha ) = \frac{side \: opposite \: to \: \alpha }{hypotenuse \: of \: triangle} [/tex]

where [tex] \ alpha [/tex] is an angle of a triangle.

In the triangle given above , [tex] \ alpha = angle A [/tex]. So,

[tex] \sin(a) = \frac{6}{10} = 0.60[/tex]

Answer:

Step-by-step explanation:

it just mental math, and i kinda forget how i even got the answer, but its 1 because she only needs 240 grams. and also 360 flour.

Answer:

I'll give you the correct answer:

a) You need to times 60 by 3: 60*3. This will get you 180g, which gets your first mark.
Next, you must times 180 by 4: 180*4. This gets you 720g, and there's your final answer + the last marks.

b) (i) 420g

 (ii) 2 packs, because there is 240 g in one pack so you times it by two.
