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:

154 2/3 m²

Step-by-step explanation:

14 1/2 x 10 2/3

First, make the mixed numbers into improper fractions:

29/2 x 32/3

Simlify by cross cancelling if you can:

29/1 x 16/3

Then, multiply:

29/1 x 16/3 = 29 x 16/1 x 3 = 464/3

Finally, turn the new improper fraction into a simplified mixed number:

464/3 = 154 2/3

The area is 154 2/3 m²

Answer:

∠DBC

Step-by-step explanation:

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

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

6c + (c - 7) + (9c - 8) + (4c + 6) =

= 6c + c - 7 + 9c - 8 + 4c + 6 =

= 6c + c + 9c + 4c - 7 - 8 + 6 = 20c - 9

Answer:

1

Step-by-step explanation:

(8/8) = 1                                 (4/8) = half                       (0/8) = 0

                                   (5/8) = a bit more than half, so is closer to 1

5/8≈1

Answer:

x = 11

Step-by-step explanation:

if we need to find the value of x then we need to

5x + 10 = 65 ( Vertically opposite angles are same )

5x = 65 -10

5x = 55

x = 55/5

x = 11

Answer:

x=11

Step-by-step explanation:

5x+10=65

5x=65-10

5x=55

5x÷5=55÷5

x=11

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.

The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Given that:

[tex]R(t) = t^2 + 7t + 159[/tex]

[tex]c(t) = t^2 + 131[/tex]

The profit function P(t) is calculated as follows:

[tex]P(t) = R(t) - c(t)[/tex]

So, we have:

[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]

Open brackets

[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]

Collect like terms

[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]

[tex]P(t) = 7t + 28[/tex]

Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Answer:

I think it -2 then -7

Answer:

The student took 28 classes

Step-by-step explanation:

What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Answer:

4 degrees every hour

Step-by-step explanation:

Since it was 48 degrees over a total of 12 hours we can do:

48 / 12 = 4 degrees.

It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.

The answer would be 6.00%

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%

Hope I helped, You can learn anything!,... Me out,... Chow,...!

No

Step-by-step explanation:

Given

- 2x + 4 = 18

note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2

However , the first step is to isolate the term in x by subtracting 4 from both sides.

- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
