Answer:

a)  x = 12

b) right triangle

Step-by-step explanation:

a) 2x + 1 + 5x + 5 + 90 = 180

    7x + 96 = 180

    180 - 96 = 84

     84 / 7  = 12

          x = 12

b) you can tell that it is a right triangle because of the square in the corner that indicates it is a right triangle

THANK YOU.

Hey there!

The answer to your question is "n = -3"

First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"

3n

Next, "5 more" represents addition, so "+ 5"

3n + 5

Finally, "is -4" means it is equal to -4, so "= -4"

3n + 5 = -4

Now that we have our equation, we can solve:

3n + 5 = -4

First, we subtract "5" from both sides of the equal sign:

3n = -9

Lastly, we divide both sides by "3".

n = -3

Have a terrificly amazing day!

Answer:

Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15  minutes before the bell rings.

Step-by-step explanation:

Total distance from home to School [tex]= 4[/tex] km

Distance travelled by Jose in first [tex]30[/tex] minutes is equal to

[tex]\frac{30}{60} * 5\\= 2.5[/tex]

Distance to travel in next [tex]15[/tex] minutes is equal to

Answer:

19.7 m

Step-by-step explanation:

Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.

Hypotenuse is 10.2 m (radius of circle)

The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees

sin 40 degrees=rise /radius=rise/10.2

sin 40=0.6428=rise/10.2

rise=10.2(0.6428)

rise=6.6 m

13.1+6.6=19.7 m

Answer:

Polynomial 1:

Simplified Form: 6x^2 - x - 1

Name by Number of Terms: trinomial

Polynomial 2:

Name by Degree: linear

Name by Number of Terms: binomial

Polynomial 3:

Simplified Form: 2

Name by Degree: constant

Step-by-step explanation:

Polynomial 1:

(x-1/2)(6x+2)

6x^2 - 3x + 2x - 1

6x^2 - x - 1

It has 3 terms, so it's a trinomial.

Polynomial 2:

There is one term with x and x is raised to the first degree, so it's linear.

There are 2 terms, so it's a binomial.

Polynomial 3:

4(5x^2-9x+7)+2(-10x^2+18x-13)

20x^2 - 36x + 28 -20x^2 + 36x - 26

28 - 26

2

Since there are no variables and the answer is just 2, it's a constant.

Answer:

A) Container X

Step-by-step explanation:

X=2C:6S  ratio, now reduce amount but keep the same ratio

X=1C:3S  

Y=4C:8S  ratio, now reduce amount but keep the same ratio

Y=1C:2S

Container X has the sweeter water because it's ratio of sugar to water is higher.

Container Y is the water sweeter.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

Container X has 2 cups of water with 6 teaspoons of sugar.

And, Container Y has 4 cups of water with 8 teaspoons of sugar.

Now,

Since, Container X has 2 cups of water with 6 teaspoons of sugar.

Hence, The ratio of water with sugar for container X = 2 : 6

                                                                                 = 1 : 3

And, Container Y has 4 cups of water with 8 teaspoons of sugar.

Hence, The ratio of water with sugar for container Y = 4 : 8

                                                                                 = 1 : 2

Cleary, We get;

⇒ 1/3 < 1/2

So, Water in Container Y is more sweeter than X.

Answer:

D) 5x + 6y = 12

Step-by-step explanation:

x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)

y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)

y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.

5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)

Answer:

They sold 175 small popcorns and 103 Large popcorns

Step-by-step explanation:

The equation is

L + S = 278 this means the total large and small popcorn that they sold is 278

3L+1S= 484  The owner of the question told me the total profit is 484

When we solve we can turn the first equation into L=-S+278

we substitute  L=-S+278 into 3L+1S=484 we get  -3S+ 834+ S= 484

-3S+834+1S=484

-2S+ 834= 484

-2S=- 350

2s= 350

s= 175

We know that they sold 175 small popcorns now. Now we Substitute 175 into L+ S= 278 and get L+ 175=278

L+175=278

L= 103

They sold 175 small popcorns and 103 Large popcorns

Answer:

(-2, 3)

Step-by-step explanation:

The solution to a system of equations is the value (or values) of x and y that satisfy both equations. we can find the value of x by setting the right sides of each of our equations equal to each other and solving:

[tex]4x+11=-2x-1\\6x=-12\\x=-2[/tex]

From here, we can simply substitute -2 for x in either of the equations to calculate y. I'll choose the bottom one:

[tex]y=-2(-2)-1\\y=4-1\\y=3[/tex]

So our solution is (-2, 3).
