Answer:

Step-by-step explanation:

All of the angles will equal up to 180

10x-10=180

180+10 is 190

190=10x     190/10=x     x=19 or R

<Q: 19*2=38-5=33    <Q:33

<P:133-5=128    <P:128

128+33+19=180,

Double checking to fact check the asnwers.

Answer:

So the whole thing is 180, we already have 3x+12, it's C.
Because A would be 3x +180 (1803x) +something else which would bring it over 180.

Step-by-step explanation:

C is the answer because 180 is the toal and it isn't going over 180 right away.

Answer:

C. (3x +12) + x = 180°

Step-by-step explanation:

(3z+12)° is obtuse. x° is acute.

Both are supplementary angles that are linear pair that add up to 180°

(3x + 12)° + x° = 180°

4x + 12 = 180°

4x = 168°

x = 42°

Plug x into (3x + 12)°

3*42° + 12

126 + 12

138°

Answer:

135 ft^3

Step-by-step explanation:

Volume of a rectangular prism is basically just width x height x depth. So the area of the base multiplied by the height. 15 x 9 = 135

Answer: 135 ft³

Step-by-step explanation:

     Volume, when dealing with a rectangular prism, is L * W * H

-> L * W can simplify to the base, as it does in the problem given to us.

V = (L * W) * H

V = B * H

V = 15 * 9

V = 135 ft³

          The rectangular prism has a volume of 135 ft³.

The area of a piece of land in scientific notation is 4.95 * 10⁶ square meters

from the question, we have the following parameters that can be used in our computation:

Area = 4,951,000 square meters

To write the area in square meters in scientific notation, we have

Area = 4.95 * 1,000,000 square meters

So, we have

Area = 4.95 * 10⁶ square meters

Hence, the area is 4.95 * 10⁶ square meters

Finding the unit rate

Answer:

x=21

y=45

z=101

Step-by-step explanation:

Angles crossing each other are congruent

86=4x+2

84=4x

x=21

Quadrilateral has 360 degrees

86 + 86 + 2y+4 + z-7 = 360

172 + 2y+4 + z-7 = 360

2y+4=94

2y=90

y=45

z-7=94

z=101

Linear is basically a straight line. It can be increasing or decreasing.

Decreasing is when on the graph, when x increases, y decreases.

On the graph, there are two parts that are decreasing. Between -2 and 0, and Between 2 and 4. Let's look at these two.

- For between -2 and 0, the line is not straight. Therefore, it is decreasing and nonlinear. We can check if this is the right answer.

- For between 2 and 4, the line is decreasing. However, the line is straight, which means it is decreasing but linear.

Your final answer is B.

Step-by-step explanation:

similar triangles means that all angles in one triangle are exactly the same as the angles in the other triangle.

and the lengths of all sides of one triangle have the same scaling factor with the lengths of the sides of the other triangle.

so, when we compare the "features" of the triangles, we see that C corresponds to S, B to R and D to T.

so, DC (50) corresponds to TS (70).

and that means that CB (60) corresponds to SR (11x - 4).

the scaling factor from BCD to RST is 70/50 = 7/5.

that means DC × 7/5 = TS.

and CB × 7/5 = SR :

60 × 7/5 = 11x - 4

12 × 7 = 11x - 4

84 = 11x - 4

88 = 11x

x = 8

The better deal will have the higher ratio of dollars per bagel.

To find the better deal, you must compare the fractions 8/7 and 6/9.

Comparng the fractions reveals that Betty has the better deal

Step-by-step explanation:

bobbs bagels: 8/7 equals 1.14, so each bagel would cost about $1.14

bettys bagels: 6/9 equals 0.66, so each bagel would cost about $0.66

$0.66 is better than $1.14 per bagel. therefore, bettys bagels are cheaper

Answer: reflection across y axis

Step-by-step explanation:

Answer:

Step-by-step explanation:

Isolate the term of t from one side of the equation.

First, you have to divide by 4 from both sides.

4t/4=40/4

Solve.

Divide the numbers from left to right.

40/4=10

First, change sides.

t+10=14

Then, subtract by 10 from both sides.

t+10-10=14-10

Solve.

Subtract the numbers from left to right.

14-10=4

First, subtract by 70 from both sides.

70-t-70=30-70

Solve.

30-70=-40

Rewrite the problem down.

-t=-40

Divide by -1 from both sides.

-t/-1=-40/-1

Solve.

Divide the numbers from left to right.

-40/-1=40

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

Answer:

4t =40 t= 10  4x10=40

10 + t = 14 t=4   10 + 4 = 14

70 - t =30 t= 40  70 - 40 = 30
