Answer:

  14

Step-by-step explanation:

The first term of the sequence is 182, and the common difference is 176-182=-6. So, the general term is ...

  an = a1 +d(n -1)

  an = 182 -6(n -1)

The 29th term will be ...

  a29 = 182 -6(29 -1)

  a29 = 14

Answer:

x = -3

Step-by-step explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)

x=-3

Step-by-step explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

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

Answer:

50 mph

Step-by-step explanation:

We have the following point

(2,100)

We know that the equation has a y intercept of 0 which means our equation looks like this

y=mx

We know that when x=2 y=100 so

100=2m

m=50

50 mph

Answer:

It’s constant by 50 (1,50) (2,125) and so on

Step-by-step explanation:

25+25=50 75+50=125 and so on

Answer:

26˚

Step-by-step explanation:

Since there is already two angles (The square in the corner shows that the angle is 90˚)

So subtract 90˚ with 64˚ which is 26˚

Answer:

this whole angle is equal to 90°

so the value of angle b = 90°-64°

so the value of b= 26.

Answer and explanation:

The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.

We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes

Surface area is therefore 16×6a²

Answer:

16 baskets of candy.

Step-by-step explanation:

78 boxes of cookies times $3 per box equals $234.

$350-$234=$116 left you need to make so-

each basket of candy earns $6, divide $116 by $6 to equal 56.

You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution

Answer:

$1507.84

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year,

then, solving our equation

I = 1240 × 0.036 × 6 = 267.84

I = $ 267.84

The simple interest accumulated

on a principal of $ 1,240.00

at a rate of 3.6% per year

for 6 years is $ 267.84.

Step-by-step explanation:

Answer:

6 elephants and 3 kangaroos in the zoo.

Step-by-step explanation:

Number of animals = 9

Number of legs seen = 30

But an elephant has 4 legs, while a kangaroo has 2 legs.

Let the number of elephant be represented by E, and the number of kangaroo by K.

So that,

E + K = 9 .................. 1

4E + 2K = 30 ............. 2

Multiply equation 1 by 2 to have

2E + 2K = 18 ............ 3

Subtract equation 3 from 1

2E = 12

E = 6

Substitute the value of E in equation 1

E + K = 9

6 + K = 9

k = 3

Thus, there were 6 elephants and 3 kangaroos in the zoo.

Answer:

y = 16

x = 2

Step-by-step explanation:

y = 8x

y = 4x + 8

then, by substitution:

8x = 4x + 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2

y = 8x

y = 8*2

y = 16

Check:

y = 4x + 8

y = 4*2 + 8

16 = 8 + 8
