Answer:

42

Step-by-step explanation:

You would substitute B where is needs to go, 7 + 3(5) + 4(5). First multiply 3 x 5 to get 15, and then multiply 4 x 5 to get 20, 7 + 15 + 20. 7 + 15 = 22 + 20 = 42. I hope this helps.

Answer:

c=-12

Step-by-step explanation:

In a triangle, the three angles ALWAYS add up to 180°

x + (6x + 10) + (x + 2) = 180

8x + 12 = 180

8x = 168

x = 21

To calculate the measure of each angle, substitute x in:

Angle A: 21

Angle B: 6(21)+10

Angle C: 21 + 2

Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.

Answer:

v = 6

Step-by-step explanation:

Given

3(3v-5) = 39

So,

3v - 5 = 39 / 3

=> 3v - 5 = 13

=> 3v = 13 + 5

=> 3v = 18

=> v = 18 / 3

=> v = 6

#HopeItHelps

Answer:

V=6

Step-by-step explanation:

Hope this helped! :)

Simplifying

3(3v + -5) = 39

Reorder the terms:

3(-5 + 3v) = 39

(-5 * 3 + 3v * 3) = 39

(-15 + 9v) = 39

Solving

-15 + 9v = 39

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + 9v = 39 + 15

Combine like terms: -15 + 15 = 0

0 + 9v = 39 + 15

9v = 39 + 15

Combine like terms: 39 + 15 = 54

9v = 54

Divide each side by '9'.

v = 6

Simplifying

v = 6

ig 174

Step-by-step explanation:

The value of the expression 3 ³/₅ - 2/3 in mixed fraction number will be 2 ¹⁴/₁₅.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ 3 ³/₅ - 2/3

Convert the mixed fraction number into a fraction number. Then we have

⇒ 3 ³/₅

⇒ 18 / 5

Then the expression is written as,

⇒ 3 ³/₅ - 2/3

⇒ 18/5 - 2/3

⇒ (18 x 3 - 2 x 5) / 15

⇒ (54 - 10) / 15

⇒ 44 / 15

⇒ 2 ¹⁴/₁₅

The worth of the articulation 3 ³/₅ - 2/3 in the blended part number will be 2 ¹⁴/₁₅.

Answer:

7.396 × 10-5

Step-by-step explanation:

To convert 0.00007396 into scientific notation, follow these steps:

Move the decimal 5 times to right in the number so that the resulting number, m = 7.396, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -5

Write in the scientific notation form, m × 10n

= 7.396 × 10-5

Step-by-step explanation:

Options :

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

Answer:

y – 8 = –0.2(x + 10)

Step-by-step explanation:

(-10, 8)

General equation in point - slope form:

y - y1 = m(x - x1)

m = slope

Given the points : ( - 10, 8)

x1= - 10 ; y1 = 8

y - y1 = m(x - x1)

Substitute the values of x and y into the equation :

y - 8 = m(x - - 10)

y - 8 = m(x + 10)

The best option which fits is :

y – 8 = –0.2(x + 10)

There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

Answer: [tex]y = \frac{2}{3} x - 2[/tex]

Step-by-step explanation:

The slope intercept form is y = mx + b

Where m is our slope and b is our y-intercept

We're given a slope of 2/3

We're given a y-intercept of -2

Substituting into y = mx + b gives

[tex]y = \frac{2}{3} x - 2[/tex]

Answer:

y = (2/3)x - 2

Step-by-step explanation:

Use the slope-intercept form y = mx + b.  Here b = -2 and m = 2/3.  Making these replacements, we get:

y = (2/3)x - 2
