Answer:

[tex]\Huge\boxed{74}[/tex]

Step-by-step explanation:

Hello There!

First things first, we need to find the value of x

If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x

180 = 2x + 3x - 5

step 1 combine like terms

2x + 3x = 5x

now we have

180 = 5x - 5 step 2 add 5 to each side

-5 + 5 cancels out

180 + 5 = 185

now we have 185 = 5x

step 3 divide each side by 5

5x/5=x

185/5=37

we're left with x = 37

Now we want to plug in 37 into x for angle A

angle a = 2(37)

2*37=74

so we can conclude that angle A = 74

Answer:

Cantidad de metros recorrida= 25 metros

Step-by-step explanation:

Dada la siguiente información:

Cantidad de vueltas= 5

Cirscunsferencia del círculo= 5 metros

Para calcular la cantidad recorrida, debemos usar la siguiente formula:

Cantidad de metros recorrida= cantidad de vueltas*cirscunsferencia del círculo

Cantidad de metros recorrida= 5*5

Cantidad de metros recorrida= 25 metros

Answer:

26 degrees.

Step-by-step explanation:

We are given

We are trying to find angle measure of j.

Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.

[tex] \tan(x) = \frac{opp}{adj} [/tex]

[tex] \tan(x) = \frac{46}{93} [/tex]

since we are trying to find the angle measure apply inverse trig function

[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]

Plug 46 for opp and 93 for adj.

[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]

which is about 26 degrees.

Answer:

x - 15 = - 20

Step-by-step explanation:

x - 15 = - 20

Add 15 to each side:

x - 15 + 15 = - 20 + 15

x = - 5

Answer:

135 points

Step-by-step explanation:

We can solve this easily, 30x4=120+15=135

So, after shopping 30 times you would have 120 points plus the 15 you got when making the account, in total 135 points.

Answer:

Sure Amaya  , the grouping is the parenthesis, right?

Step-by-step explanation:

so  just add up.. the things outside of the parenthesis

-  [tex]4^{2}[/tex] * 4

so exponents come first in the order of what to do... right?

[tex]4^{2}[/tex] =16    okay , got that part, the next part is

16 * 4 = 64   okay got that part,  now

- 64   is what is subtracted from the grouping   , got it?

Answer:

-1.25

Step-by-step explanation:

a=15

b=-5

If you plug the values into the equation you get

-5^2/15+5

-25/20

If you simplify that you will get:

-4/5

Or:

-1.25

Answer: 12.1 meters

Step-by-step explanation:

This is a rectangular fence so it represents a rectangle.

Fencing the garden will require going around it therefore you are looking for the perimeter.

Perimeter of a rectangle = (2 * Length) + ( 2 * Width)

= (2 * 315) + ( 2 * 290)

= 1,210 cm

Convert to meters:

A meter is 100 centimeters

= 1,210 / 100

= 12.1 meters

Answer:

-3x+3=5x+19

5x+3x=3-19

8x=-16

x=-2

Hope this helps <3

Answer:

x = -2

Step-by-step explanation:

we know,

y is common in both

so ,

-3x + 3 = 5x + 19

-3x +3-19=5x

-3x - 16 = 5x

-3x -5x = 16

-8x = 16

x = 16 / -8

x= -16/8

x= -2

also if you put value of x = -2 in both the expression you will get y = 9

Step-by-step explanation:

h(t)=30000-2000t

A) h(5)=30000-2000(5)=20000ft

B) h(8)=30000-2000(8)=14000ft

C) h(12)=30000-2000(12)=6000ft

D) 30000-2000t=0

2000t=30000

t=15 minutes.

Answer:

-12

Step-by-step explanation:

(-5)-(7) can easily be called -5-7 when all the brackets are taken away

-5-7= -12

Answer:

You can use the additive inverse to solve for x

Step-by-step explanation:

The additive inverse acquits you to change two things: the negative sign and -7

Therefore, after implementing the additive inverse, here's your expression: -5 + -7. Remeber, the rule for adding negative rational numbers: the sum of 2 negative numbers will be negative. Therefore, simply add 7 + 5 to get 12. Remebering out rule of adding negative rational numbers, you should receive -12 as your answer.

Hi! i see your having trouble let me help you :-)

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

−4(x−3)=20

Step 1: Simplify both sides of the equation.

−4(x−3)=20

(−4)(x)+(−4)(−3)=20(Distribute)

−4x+12=20

Step 2: Subtract 12 from both sides.

−4x+12−12=20−12

−4x=8

Step 3: Divide both sides by -4.

−4x−4=8−4

x=−2

x=−2

Answer:

x = 70

Step-by-step explanation:

The total sum of all of the angles in a parallelogram is equal to 360 degrees. Opposite angles are also congreuent meaning that angle ADC and angle ABC are equal. Adding the sum of the two angles gives you 220. Subtract 220 form 360 and you get 140 which is equal to the sum of angles BCD and BAD. Angles BCD and BAD and the sam so dividing 140 by 2 would give you the angle measure of x.

Answer:

a) )12,6)

b) (12,2)

c) (4,-7)

d) (9,-7)

Step-by-step explanation:

a) Dilation

When we dilate, we multiply the given scale factor by each of the coordinates

We have this as follows;

(20 * 3/5, 10 * 3/5) = (12, 6)

2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value

We have this as;

(7+ 5, 8-6) = (12,2)

3. By reflecting across the x-axis

we have (x,y) changing to (x,-y)

so we have ;

(4,7) becomes (4,-7)

4. Rotation by 270 degrees (7,9)

If clockwise;

(x,y) becomes (y,-x)

so we have

(7,9) becoming (9,-7)
