Step-by-step explanation:

- 50 + (5 / 13)p this says negative 50 plus 5/13 times p

if p = -26 what does this epression evaluate to?

- 50 + (5 / 13) × p p = -26 substitute the value of p into the expression

- 50 + (5 / 13) × (-26)

- 50 + (5 (-26) / 13) I just rewrote the expression to make it clearer

that the -26 in -26/1 and the 5 in 5 / 13 are

both in the numerator over denominator 13

- 50 + (5 (-26) / 13) -26 / 13 evaluates to -2

-50 + (5)(-2)

-50 + (-10)

-50 - 10

-60

Answer:

Missing Truck Value=6

Missing Car Value=45

Step-by-step explanation:

Since the ratio of trucks to cars is 2:3, you do 3 times 3 equals 9. Since all 3 ratios needed to be equal, we have to do 2 times 3 which is 6. That is how you get the truck value. We do the same to get the car value. 6 times 5 is equal to 30, so we do 9 times 5 too. That gives you 45.

Points A and B have opposite x-coordinates but the same y-coordinates. On a coordinate plane, point A is 2 units to the left and 3 units up. Point B is 2 units to the right and 3 units up. How many units away are each of the points from the y-axis? 2 3 4 5

Answers

Answer: 5

Step-by-step explanation: If you take minus 2 and take it to 0 then add 3 you get 5

The points A and B are 2 units away from the y-axis.

What is Cartesian coordinates system?"It is used to specify the location of a point in two-dimensional plane or three-dimensional space.""The cartesian plane is a two-dimensional coordinate plane, formed by the intersection of the x-axis and y-axis."What is the distance of point from Y-axis?

"The distance of a point from the Y-axis is its x-coordinate."

For given question,

Points A and B have opposite x-coordinates but the same y-coordinates.

Point A is 2 units to the left and 3 units up.

So the point A has coordinates (-2, 3)

Point B is 2 units to the right and 3 units up.

So the point B has coordinates (2, 3)

We know that the distance of a point from the y - axis is its x-coordinate.

So, the distance of point A from the y-axis is |-2| = 2 units

And the distance of point B from the y-axis is 2 units

Therefore, points A and B are 2 units away from the y-axis.

Find the area of the polygon.

Answers

Answer: use formulas for area of square/triangle

Step-by-step explanation:

1st one is a rhombus so use A= BH

which is 5x4 = 20

2nd one is a kite

i assume you have not learnt the formula for kites so u can use triangles (A=1/2BH)

triangle CBA: 1/2 x (6+6)(2) = 12

triangle ACD: 1/2 x (6+6)(10)= 60

area = 12 + 60 = 72

green/first polygon:

Four equal triangles inside a polygon, so we have to find an area of one triangle and multiply that area with four since there are four triangles in total.

base is 5, height is 4. area of triangle formula: A = (bh) / 2 = (5x4) / 2 = 20 / 2 = 1010 x 4 = 40 (b/c there are four equal triangles)40 square units is the area of green/second polygon

________________________________________________________

teal/second polygon:

Two equal triangles and another two (different) equal triangles, so we have to find an area of a smaller triangle and multiply that area with two since there are two equal smaller triangles.

Then we have to find an area of a larger triangle and multiply that area with two since there are two larger equal triangles.

(smaller triangle)base is 6, height is 2. area of triangle formula: A = (bh) / 2 = (6x2) / 2 = 12 / 2 = 66 x 2 = 12 (b/c there are two equal smaller triangles)12 square units of the area of two equal smaller triangles (so we're not done yet!)

------------------------------------------------------------

(larger triangle)base is 10, height is 6. area of triangle formula: A = (bh) / 2 = (10x6) / 2 = 60 / 2 = 3030 x 2 = 60 (b/c there are two equal larger triangles)60 square units of the area of two equal larger triangles

12 + 60 = 72

72 square units is the area of teal/second polygon.

Miguel recently sold some farmland and bought a new plot that consists of 968 acres. Miguel calculates that this is 20% less acreage than he used to own. What was the acreage of the old land?

Answers

Answer:

1210 acres

Step-by-step explanation:

Given data

let the old farmland be x acres

new farmland = 968 acres

therefore

let us find 20% of the old farmland

=20/100x

=0.2x

Hence

968+0.2x=x

collect like terms

968=x-0.2x

968=0.8x

x= 968/0.8

x=1210 acres

A rectangle has a width represented by the expression-2x+20. The length of the rectangle is 6 more than twice the width. Which expression represents the area of the rectangle?

Answers

Rectangular Areas and Perimeters

The perimeter of a rectangle is given by:

[tex]\boxed{\bold{Perimeter = 2 (length + width)}}[/tex]

In the problem we have these data:

Length = a Width = -2x + 20 Perimeter = 6 + 2 (-2x + 20)

We replace the data in the equation of the perimeter:

6 + 2 (-2x + 20) = 2 (a - 2x + 20)

We apply distributive property:

6 - 4x + 40 = 2a - 4x + 40

6 = 2a

6 ÷ 2 = a

3 = a

⇒ Length = 3

The area of the rectangle is given by:

[tex]\boxed{\bold{Area = 2 (length + width)}}[/tex]

We have these data:

Length = 3 Width = -2x + 20

We replace the data in the equation of the area:

Area = (3) (- 2x + 20)

We apply the distributive property and obtain:

Area = -6x + 60

The expression representing the area of the rectangle will be -6x + 60

Why do you think there is a limit on the number of times you can withdraw or transfer money in your savings account?

Answers

Answer:

I think that there is a limit on the number of times you can withdraw or transfer money in your savings account because banks only maintain a small percentage of the money people deposit on the savings accounts and most of the money is used for loans and they need to limit that to be able to have enough reserves to cover the withdrawals. If they don't put a limit people can try to withdraw all the money at the same time and the bank would not have the funds to cover that.
