Answer:

he needs  15 more dollors, and they could be a 10 and a five, 15 ones, or 3 5s.

Step-by-step explanation:

20+20+20+10+10= 80

95-80= 15

10+5= 15

1 x 15= 15

5 x 3 = 15

therefore, he needs 15 more dollors, and they could be a 10 and a five, 15 ones, or 3 5s.

Answer:

x=-18

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well we'd just solve the equation!

-7+1=-1+x/3+1

-6*3=x/3*3

x=-18

And to check:

-1+-18/3

-1-6=-7

-7 = -1 + [tex]\frac{x}{3}[/tex]

To solve this you must isolate x.

On the right side of the equation the one is negative. To cancel the -1 from the right side you must add 1 to both sides (what you do to one side you do to the other) since addition is the opposite of subtraction (negative). Doing this will make -1 zero on the right side of the equation and bring it over to the left side

-7 + 1 = -1 + 1 +  [tex]\frac{x}{3}[/tex]

-6 = 0 +  [tex]\frac{x}{3}[/tex]

-6 =  [tex]\frac{x}{3}[/tex]

The x is being divided by 3 and the opposite of division is multiplication.  To completely isolate x you must multiply 3 to both sides. This will cancel the three out on the right side of the equation and bring it over the left side.

-6 * 3 = [tex]\frac{x}{3}[/tex] * 3

-18 = x

Now check:

-7 = -1 + [tex]\frac{-18}{3}[/tex]

-7 = -1 + (-6)

-7 = -7

^^^This is true which means that x = -18

I hope this helped! Let me know if you have any questions

Answer:

176

Step-by-step explanation:

option a ( 176 cm²)

A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters.

To find the area, we use the formula for the area of a trapezoid:

Area = 1/2 × (Base1 + Base2) × Height

Here, Base1 is 12 cm,

Base2 is 10 cm, and

the height is 16 cm.

the sum of the bases:

12 cm + 10 cm

= 22 cm.

Multiply by the height:

22 cm × 16 cm

= 352 cm².

Divide by 2 to get the area:

352 cm² ÷ 2

= 176 cm².

So, the area of the trapezoid is 176 cm².

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

[tex]y = mx + b[/tex]

where m=3 is the slope .

We substitute the slope to get:

[tex]y = 3x + b[/tex]

We substitute the point to find b.

[tex] - 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4[/tex]

The equation of the straight line is:

[tex]y = 3x + 4[/tex]

[tex] \frac{2 {x}^{4} + 2 {x}^{3} + 2 {x}^{2} + 2 {x}^{2} - x - 1 }{ {x}^{2} - x - 1 } [/tex]

We carry out the polynomial division in the attachment to obtain:

[tex]\frac{2 {x}^{4} + 2 {x}^{3} + 2 {x}^{2} + 2 {x}^{2} - x - 1 }{ {x}^{2} - x - 1 } = 2 {x}^{2} + 4x + 8 + \frac{11x + 7}{ {x}^{2} - x - 1 } [/tex]

The total number of miles the car can travel in 6 hours is A. 6x miles per hour

To calculate the miles the car will travel in six hours

By using the formula of Distance = Rate * Time

Given that,

Average rate is given as "x" miles per hour

the time = 6 hours

To calculate the total miles in 6 hours = x * 6 miles per hour

Total miles = 6x miles per hour

Therefore, the total number of miles the car can travel in 6 hours is 6x miles per hour

6x divided by 6 will be equal to x.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 6x is divided by 6. The solution will be done as below:-

E = 6x / 6

Divide 6 by 6 we will get 1. The value of expression will be:-

E = x

Therefore, 6x divided by 6 will be equal to x.
