Let's substitute the value of x as 8 in the given equation to find the value of y ~

  • \sf2x + y = 12

  • \sf(2 \times 8) + y = 12

  • \sf16 + y = 12

  • \sf y = 12 - 16

  • \sf y =  - 4

A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?
Arturiano [62]

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2\pir

Thus,

Circumference of the track  = 2 x \frac{22}{7} x 1.5

                           = 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

                                       = 330 miles

The total distance traveled by the car is 330 miles.

If EFGH is a parallelogram, what is the value of x?
Vladimir [108]

Based on the property of the consecutive angles of a parallelogram, the value of x is calculated as: E. 37.

<h3>What are the Properties of the Angles of a Parallelogram?</h3>

In a parallelogram, the angles that are opposite to each other are congruent while consecutive angles are supplementary.

Angles F and G are consecutive angles and are therefore supplementary (have a sum of 180 degrees.)

Angle F + angle G = 180

4x - 2 + 34 = 180

4x + 32 = 180

4x = 180 - 32

4x = 148

x = 148/4

x = 37

Value of x is: E. 37.

Write the number five million four thousand three hundred in standard form
valentinak56 [21]

Written numerically, the number you stated is written as:

5,004,300

Standard Form (Scientific Notation) numbers are written as a decimal (n.m) such that there is [normally] only one digit (n) to the left of the decimal point, and the rest of the number (m) to the right (with a possible limit). If there is only a single digit in the whole number then the value on the right is a zero (n.0).

To show that the value shown has shifted its decimal point position, the number of decimal positions shifted is shown after the number as a 10’s multiplied to the power of the number of positions shifted.

e.g., 102 = 102.0 = 1.02 (decimal point shifted left two places. If smallest digit is 0 then ignore it UNLESS it’s the ONLY digit!!)

1.02*10^2(2 Decimal shift to the left)

1.02*10^2

So, for the number asked in the question:

5,004,300 = 5,004,300.0

Left shift 6 times to largest digit = 5.004300

5.004300 (show the shift multiplier: 10^6)

5.004300*10^6
