Answer:

∠DBC

Step-by-step explanation:

Since ∠ABD shares the same vertex and side with ∠DBC, then they are adjacent angles.

Answer:

Jessica is 14 years old.

Step-by-step explanation:

Let [tex]o[/tex] equal Olivia's age, let [tex]j[/tex] equal Jessica's age, and let [tex]d[/tex] equal Daniel's age. With this lets write out what we know:

[tex]d = 7[/tex]

[tex]o = d + 2 = 7 + 2 = 9[/tex]

[tex]o = j - 8 + 3 = j - 5[/tex]

[tex]9 = j - 5[/tex]

[tex]j = 9 + 5 = 14[/tex]

Answer:

Step-by-step explanation:

Có: 7(x+y+z)=5

=>x+y+z = 5/7 (1)

Lại có:

+) y(x+y+z)=9

=>y×5/7=9

y=9: 5/7

y=63/5 (2)

+) x(x+y+z)=-5

=>x×5/7=-5

x=-5:5/7

x=-7 (3)

Từ (1);(2) và (3) => -7+63/5+z =5/7

=>28/5+z=5/7

=>z=-171/35

Vậy ....

Answer:

Step-by-step explanation:

z = 102 degree (opposite angles of a parallelogram are equal)

z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)

102 + x + 34 = 180

x = 180 - 136

x = 44 degree

y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)

y + 102 + 44 = 180

y = 180 - 146

y = 34 degree

Answer:

x = 44°, y = 34°, z = 102°

Step-by-step explanation:

The opposite angles of a parallelogram are congruent , then

∠ z = 102°

Consecutive angles are supplementary , then

x + 34° + 102° = 180°

x + 136° = 180° ( subtract 136° from both sides )

x = 44°

∠ y = 34° ( alternate angle

Answer:

$14.20

Step-by-step explanation:

First we add both the meal ($55.25) and the dessert ($15.75) to calculate the total cost which would be $77.00 Assuming the bill was evenly split among the five people, we would divide the total cost ($77.00) by all 5 people which gives us 14.20 so each person would have to pay $14.20.

Answer:

4500cm^3

Step-by-step explanation:

To find the volume multiply the length × width × height

25×18×10=4500

Answer:

4,500 cm³.

Step-by-step explanation:

Since L × W × H = V(olume), we get 25 × 18 × 10 which equals 4,500 cm³.

Answer:

D

Step-by-step explanation:

We can cross off a because it is impossible to have negative of a material.

Now lets get into the System of equations. First subtract both of them to have one common variable(we will find the second one later)

- P + N = 134

- P + 3.1N = 241.10

2.1N = 107.1

107.1/2.1 = 51

Now we know that n = 51

lets substitute,

P + 51 = 134

P = 83

Lets check

83  + 51 = 134

Answer:

C

Step-by-step explanation:

First of all it's not that you aren't very good at math it's just that you don't YET understand the concepts,... Believe me when I say that I've been there!!!

To solve this problem you have to look at it as a solve for the unknown problem,... They say that The FORMULA (important) is the following:

S = Ar

This can be written:

S = A * r

They then say that

S = sales tax,

A = cost of the product

r = local sales-tax rate,...

THEN they start giving you information,... they say the COST of a television (cost of the product) is $400 dollars you can now enter this info in you formula,... A = cost of product,... so switch the letter with the assigned info,...

S = $400 * r

...and the sales tax is $24 dollars,... S stands for sales tax so switch the variable for the dollar amount,...

$24 = $400 * r

Now you just have to solve the equation (figure out $400 * what = $24) and easy way to do this is to simply divide $24 by $400,...

$24/$400=0.06,...

0.06 = 6.0% = 6.00%

Answer:

5 1/4 - 2 2/3 = 31/12 = 2 7/12 = 2.5833333

Step-by-step explanation:

1. Conversion a mixed number 5 1/4 to a improper fraction: 5 1/4 = 5 1/4 = 5 · 4 + 1/4 = 20 + 1/4 = 21/4

To find new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/4 = 20/4

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

Five and one quarter is twenty-one quarters

Conversion a mixed number 2 2/3 to a improper fraction: 2 2/3 = 2 2/3 = 2 · 3 + 2/3= 6 + 2/3 = 8/3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3 = 6/3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Subtract: 21/4 - 8/3 = 21 · 3/4 · 3 - 8 · 4/3 · 4 = 63/12- 32/12 = 63 - 32/12 = 31/12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 3 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - twenty-one quarters minus eight thirds = thirty-one twelfths.
