What is 3x+3=-27 what is x

Answers

Answer 1

Answer: Subtract 3 from each side:

3x = -30

Divide each side by 3 :

x = -10

Answer 2

Answer: $3x + 3 = -27 \n 3x = -27-3 = -30 \n x = -30/3 = -10 \n Thus, x = -10$

864

Step-by-step explanation:

Lettherequirednumber be'x'

AccordingtotheQuestion,

$x / 12 = 72$

Writethedivision asfraction

$(1)/(12) x = 72$

Multiplybothsidesof theequationby12

$(1)/(12) x \: * 12 = 72 * 12$

Calculate:

$x = 864$

Final answer:

The number that when divided by 12 equals 72 is 864. This is found by multiplying the divisor (12) with the desired quotient (72). Therefore, the answer is 864.

Explanation:

To solve for the number that when divided by 12 gives an answer of 72, we need to leverage the standard division operation in mathematics.

To find this number, we simply multiply 12 (the divisor) by 72 (the quotient). This is the reverse of the division process, also known as multiplication.

When we perform this calculation, 12 multiplied by 72, we find the answer to be 864. Therefore, 864 is the number that when divided by 12 gives you 72.

The diagonal of a rectangular big screen tv screen measures 152cm. The length measures 132cm. What is the height of the screen?

Answers

Hi!
We use the pithagorean theorem: height^2 = 152^2 - 132^2 = 5680;
height = $√(5680) = 75.36cm;$

The table and the graph each show a different relationship between the same two variables, x and y:A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,180 and 4,240 and 5,300 and 6,360. On the right of this table is a graph. The x axis values are from 0 to 10 in increments of 2 for each grid line. The y axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2, 70 and 4, 140 and 6, 210 and 8, 280 is drawn.

How much more would the value of y be in the table than its value on the graph when x = 11?

Answer:

The value of y be in the table is 275 more than its value on the graph when x = 11.

Step-by-step explanation:

The slope represent the changer is y with respect to change in x.

$Slope=(y_2-y_1)/(x_2-x_1)$

From the table it is noticed that the value of y increased by 60 as the value of x increased by 1. Therefore the slope of the function is 60. It is also calculated by the formula. The two points from the table are (3,180) and (4,240).

$Slope=(240-180)/(4-3)=60$
