Mrs. Delgado purchased notebooks at 2 for $5 and pens

at $2 per package. She spent $19 for a total of 8 items.

How many notebooks and pens did she buy?

Answer:

59.6%

Step-by-step explanation:

You add all of the number up and divide by 5

Answer:

59.6 which is a D - this is still a passing grade, (between 59% and 69%)

Answer:

y = -3x + 13

Step-by-step explanation:

y - 4 = -3(x - 3)

y - 4 = -3x + 9

y = -3x + 9 + 4

y = -3x + 13

Answer:

$7

Step-by-step explanation:

Let the price of a box of popcorn = b and the price of a program = p

we can make 2 equations:

5b+3p = 41 and 3b+2p=26

We can use the subtraction method be able to eliminate one of the variables and isolate the other one - to do it I will equalize the 'b' in both equations by multiplying by 5 and 3 respectively

5(3b+2p=26)

-3(5b+3p = 41)

15b+10p=130

-(15b+9p=123)

p=7 (therefore the answer is 7$)

The equation that represents Genevieve's brother is y = 18/2.

The equation that represents Genevieve's age:

21 = 3 + 2Y

Where Y represents Genevieve's brother age

In order to determine the required equation, make y the subject of the formula

21 - 3 = 2y

18 = 2y

y = 18/2

Answer:

10

Step-by-step explanation:

440=2(60+6x+10x)

220=60+16x

160=16x

x=10

h=10

The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.

We have been given data as:

a = 10, b = 6 and s = 440

The surface area of the rectangular prism is given by the formula

⇒ S = 2(ab + bh + ah)

Substitute the values of a = 10, b = 6 and s = 440 in the above formula

⇒ 440 = 2(60 + 6h + 10h)

⇒ 220 = 60 + 16h

⇒ 220 - 60 = 16h

⇒ 160 = 16h

⇒ 16h = 160

⇒ h = 160/16

⇒ h = 10

Therefore, the required value of h is 10.

To find:

The solution of the given inequality.

Solution:

We have,

[tex]\dfrac{4}{3}<-\dfrac{8}{3}y[/tex]

Multiply both sides by 3.

[tex]4<-8y[/tex]

Divide both sides by -8 and change the sign of inequality.

[tex]\dfrac{4}{-8}>\dfrac{-8y}{-8}[/tex]

[tex]-\dfrac{1}{2}>y[/tex]

It can be written as:

[tex]y<-\dfrac{1}{2}[/tex]

Therefore, the correct option is A.

Step-by-step explanation:

Formula  

multiply the length value by 10

By the triangle congruence we can use the SSA method to prove the base angles are congruent.

If two or more triangles are congruent, it depends on how big their sides and angles are. The three sides and three angles of a triangle determine its size and shape, accordingly. Two triangles are said to be congruent if the pairings of respective sides and corresponding angles are equal.

These are exactly the same size and shape. There are several different congruence conditions that triangles might meet.

In the figure given,

It is necessary to demonstrate the congruence of the triangles PYX and QXY.

Both triangles have the same XY base.

PX must equal QY because the lines PX and QY are perpendicular on congruent sides.

Angles PYX and QXY are equal since the axiom "Angles opposed to equal sides are equal" states that they are.

As a result, it can be shown that the two triangles PYX and QXY have two sides and an equal angle.

As a result, using SSA criteria, the two triangles will be congruent.

Hence, option C is the best one.

Answer:

Tom will need 42 bags of seed.

Step-by-step explanation:

The area of Tom's yard is 630 square feet.

Divide the area (630) by the amount of area that each bag of seed covers (15)

630 divided by 15 is 42. So, Tom will need to use 42 bags of seed to cover his whole yard.
