math is so hard too me help​

Answer:

Step-by-step explanation:

get b by itself

15-1/2b= -3

-15          -15

-1/2b=-18

multiply by -2

-1/2b=-18

*-2      *-2

b=36 ( it's positive because two negatives make a positive)

Answer: a. Lin's tank hold 20 cups and Elena's tank hold 20 gallons; I know this because gallons are greater than cups.

Step-by-step explanation:

Gallons are greater than cups so the fish tank that will hold 20 gallons would have to be the bigger one which in this case is Elena's.

With cups being lesser in quantity than gallons, the fish tank that will hold 20 cups of water will definitely have to be the smaller one which in the case is Lina's.

Answer:

Cashier scanned the bread twice.

Step-by-step explanation:

= 2.49 + 2.19 + 1.47 + 0.87 = 7.02

= 7.02 + 0.75 = 7.77

= 7.77 + 0.04 = 7.81

With 2 dollars and 19 cents leftover, even if the pennies were changed to dimes, youd still have only get up to 8.17 which still leaves 1 dollar and 83 cents leftover.

With that eliminated what could have the cashier miss-scanned? The paper towels are incorrect because 1.47 + 7.81 doesnt make 10 dollars

The dishwashing liquid isn't right either, because 0.87 + 7.81 doesn't make 10 dollars aswell.

The milk is also incorrect because 2.49 + 7.81 doesnt make EXACTLY 10 dollars. The bread is to correct answer bevause 2.19 + 7.81 equals exactly 10 dollars.

Hope this helps :)

Step-by-step explanation:

The attached figure shows a circle. In this circle, some of the part is shaded with a color.

In the figure, we have drawn lines from red color. It shows that there is 1 part shaded out of 4 parts.

Carla said The shaded angle represents 1/4 of the circle while Adam states the shaded angle represents 3/8 of the circle.

The fraction for the shaded part is 1/4. Hence, Carla is correct.

Answer: 11 hours 30 minutes

Step-by-step explanation:

Total flight distance:

= 8,300 + 5,500

= 13,800 km

Flight time = Distance / Speed

= 13,800 / 1,200

= 11.5 hours

= 11 hours 30 minutes

Answer:

you add 8 2/5 and 6 1/2. the common denominator is 10, and when you add, you get 14 9/10. then you subtract

24 - 14 9/10 and you get 9 1/10

Answer:

There are no solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

5(3x+9)−2x=15x−2(x−5)

Step 1: Simplify both sides of the equation.

5(3x+9)−2x=15x−2(x−5)

(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)

15x+45+−2x=15x+−2x+10

(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)

13x+45=13x+10

13x+45=13x+10

Step 2: Subtract 13x from both sides.

13x+45−13x=13x+10−13x

45=10

Step 3: Subtract 45 from both sides.

45−45=10−45

0=−35

There are no solutions.

Step-by-step explanation:

It goes through that one on the graph

Answer:

From the lines we know that that two sides are the same so the other angle is also 6x

the total of a triangle equals 180 so

6x+6x+3x=180

15x=180

x=12

Answer:

a) 84 minutes ☺️☺️

Answer:

Essentially, slope is rise/run. Rise is how many units up the graph, and run is how far to the left or right it goes. Rise will be negative if it's going down, and run will be negative if it's going left. There's two ways to find the slope in this case.

1. Stick to the more visual aspect of it, and count how many units up from one point to the next point. Point (1,2) is 2 units up from point (0,0). Then you count how many units right or left it goes. In this case, it's 1 towards the right. This means the rise/run comes out to be 2/1, which means the slope=2.

2. Look at the equations. y=mx+b is the linear format for these lines. y is the y coordinate, m is the slope, x is the x coordinate, and b is the y intercept (the point where x=0). These two lines have shared slope values, which means the slope for both of them is 2.

(please brainliest?)

Answer: 0

Step-by-step explanation:

Slope is rise/run so if the y value is stagnant (10 in this case) then the line is horizontal and has no slope

Answer:

B.

Step-by-step explanation:

BC and YZ are the two angles at the end of both equations, and will always line up in the triangle.

(hope this helps!)

Given that triangle ABC is congruent to triangle XYZ, the statement from the given options that is always true is:

B. [tex]\mathbf{\overline{BC} \cong \overline{YZ}}[/tex]

Recall:

Thus, given that triangle ABC and triangle XYZ are congruent to each other, it means that:

<A is congruent to <X

<B is congruent to <Y

<C is congruent to <Z

AB is congruent to XY

BC is congruent to YZ

AC is congruent to XZ

Therefore, given that triangle ABC is congruent to triangle XYZ, the statement from the given options that is always true is:

B. [tex]\mathbf{\overline{BC} \cong \overline{YZ}}[/tex]

Answer:

Step-by-step explanation:

i used a calculator to do 1500 ×4.5%

Answer:

you would multiply 1500 × 4.5%= 65.5

Step-by-step explanation: In order to factor an integer (the 8 in the fraction 1/8) we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5)

The number that each prime divides the original integer becomes it's exponent in the final result.

In the example: [tex]\frac{1}{8} x+16[/tex]

Prime number 2 to the power of 3 equals 8.

[tex]\frac{1}{2^3} x+16[/tex]

Now, we need to perform a multiplication. The following rule is applied: [tex]\frac{A}{B} C=\frac{AC}{B}[/tex]

In the example: [tex]\frac{1}{2^3} x+16[/tex]

The new factors in the numerator are: 1x.

Notice that all non-fractions are placed in the numerator.

The factors in the new denominator are: [tex]2^3[/tex]

[tex]\frac{x}{2^3} +16[/tex]

Now, we need to add the fractions. We use this rule: [tex]\frac{A}{B} +\frac{C}{D} =\frac{\frac{LCD}{B}A+\frac{LCD}{D}C }{LCD}[/tex]

The example involved 2 terms. [tex]\frac{x}{2^3} +16[/tex]

Note that 1 non-fractional term are treated as fractions with a denominator equal to 1.

The LCD is: [tex]2^3[/tex]

[tex]\frac{x}{2^3} +16[/tex]changes to[tex]\frac{x+(2^3)16}{2^3}[/tex]

We need to evaluate a power by multiplying the base by itself as many times as the exponent indicates.

In the example: [tex]\frac{x+(2^3)16}{2^3}[/tex]  (the one in parenthesis)

Base 2 will be multiplied by itself 3 times.

2 x 2 x 2 = 8 ([tex]2^3[/tex] = 8)

[tex]\frac{x+8\times16}{2^3}[/tex] (Notice that [tex]2^3[/tex] is now 8 in the fraction.)

Lastly, we multiply the 8 by 16 in the fraction, [tex]\frac{x+8\times16}{2^3}[/tex]

8 x 16 = 128

[tex]\frac{x+128}{2^3}[/tex] (Notice that 8 x 16 is now 128 in the fraction)

Therefore, your answer is: [tex]\frac{x+128}{2^3}[/tex]

Step-by-step explanation:

Percentage of full time employees who ride bus to and fro from work?

Since the table as been arranged as a two way frequency table., we only need to find the value at the intersection of the two Given conditions ;

Horizontally, the type of ride = bus

Vertically, the type of employee = full-time

Hence, full time employees who take bus to and fro = 0.17

As a percentage =, (0.17 * 100) = 17%

Answer:

AC = 40

Step-by-step explanation:

A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.

A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other. The diagonals of a parallelogram bisect each other.

Given parallelogram ABCD:

Diagonals AC and BD bisect each other at point E. Hence:

AC = AE + CE (line segment addition postulate)

Also:

AE = CE (diagonal BD bisects AC at point E).

Hence; x + 16 = 5x

5x - x = 16

4x = 16

x = 4

AE = x + 16 = 4 + 16 = 20; CE= 5x = 5(4) = 20

AC = AE + CE = 20+ 20 = 40
