What is the value of this expression?

​ 1.5(−2.4+(−5.3))

Answers

Answer 1

Answer:

-11.55

Step-by-step explanation:

(to get the numbers out of the brackets you have to multiply all the numbers in the brackets to the number that is there, and in this case its 1.5)

1.5x(-2.4)= -3.6

1.5×(-5.3)= -7.95

after that, you add them (because there is a plus sign, not a minus, multiplication sign or a division sign.)

-7.95+ -3.6= -11.55

answer= -11.55

Answer:

  x = (y +2)/3

Step-by-step explanation:

The flowchart is trying to help you see that you "undo" what is done to x, in reverse order.

  x is first multiplied by 3, then -2 is added.

First, we want to undo the addition of -2, so we add the opposite of that to y:

  y = 3x -2   ⇒   y +2 = 3x

Then we want to undo the multiplication by 3, so we divide by 3:

 y +2 = 3x   ⇒   (y +2)/3 = x

The solution for x is ...

  x = (y +2)/3

Additional comment

In your diagram, each box has the inverse operation of the one in the box above it. The inverse of subtracting 2 is adding 2. The inverse of multiplying by 3 is dividing by 3. The arrows connecting the boxes are intended to show you that these inverse operations occur in the reverse order of the original operations, as we described above. (The small box at bottom center might contain "3x".)

The rectangular screen on a laptop has an area of 375 cm ^ 2 Its width is 10 cm less than its length. What are the dimensions of the screen?

Answers

Answer:

lenght = 25 cm

widht = 15 cm

Step-by-step explanation:

Dimensions of the screen

375 = (l - 10) × l

375 = l² - 10l

l² - 10l -375 = 0

(l + 15)(l -25)

l = -15 or l = 25

lenght = 25 cm

widht = 25 - 10

widht = 15 cm

On a trip, a student drove 42 miles per hour for 3 hours and then drove 26 miles per hour for 5 hours. What is the student’s average rate of speed, in miles per hour, for the whole trip? *
1. 126 MPH
2. 32 MPH
3. 130 MPH
4. 8.5 MPH

Answers

Answer:

34 mph

Step-by-step explanation:

Average speed = total distance / total time

Total distance = ( 40 × 2 + 30 × 3 )

= 170 miles

Total time = 5 h

So, avg speed = 170/5 = 34 mph

[tex]\frac{4}{21}[/tex]

Step-by-step explanation:

In order to find the answer you need to find the common denominator of the two fractions multiply the fractions to receive that common denominator and then subtract to find your answer.

[tex]\frac{1}{3} -\frac{1}{7}[/tex]

Find the common denominator:

[tex]CD=21[/tex]

[tex]1\times7=7[/tex]

[tex]3\times7=21[/tex]

[tex]=\frac{7}{21}[/tex]

[tex]1\times3=3[/tex]

[tex]7\times3=21[/tex]

[tex]=\frac{3}{21}[/tex]

[tex]\frac{7}{21} -\frac{3}{21}[/tex]

Subtract numerators

this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer

Answer:

LENGTH - 3cm / WIDTH - 2cm

Step-by-step explanation:

Well first off, you would use the scale: 1 cm = 4 ft

With 12, you divide by 4. 12 ÷ 4 = 3

With 8, you also divide by 4. 8 ÷ 4 = 2

So, it would be 3 cm long and 2 cm wide.

Evaluate each function for the given input values. For f (x)=2/3x+ 3, find f (x) when x= 9 and when x=-3

Answers

Answer:

Step-by-step explanation:

f(x) = 2/3 x + 3

x = 9

f(9) = 2/3 * 9 + 3            Divide 9 by 3

f(9) = 2 * 3 + 3               Combine 2 * 3

f(9) = 6 + 3                    Combine

f(9) = 9                          The answer is just a coincidence. The answer for the next one shouldn't be - 3

f(-3) = 2/3 *(-3) + 3         Divide 3 into - 3

f(-3) = 2*(-1) + 3

f(-3) = -2 + 3

f(-3) = 1

A street sign is in the shape of an isosceles triangle that has a base of 6.5 inches bigger than either of the equal sides. If the perimeter of the triangle is 65 inches, what is the length of the equal sides?

Answers

Answer:

19.5

Step-by-step explanation:

side is 6.5 bigger, so minus the 6.5 from the total perimeter of 65 and divide by 3.

65- 6.5 = 58.5

58.5 ÷ 3 = 19.5

equal sides are 19.5

longer side is 19.5 + 6.5

Answer:

19.5 inches

Step-by-step explanation:

You can interpret this problem as x + x + (x + 6.5)=65, with x being the length of the equal sides.

Simplified, this equation becomes 3x+6.5=65.

Solving, this becomes 3x+6.5-6.5=65-6.5 which comes out as 3x=58.5. Next, we divide this equation by 3 on both sides, which then comes out to x=19.5. Therefore, the length of equal sides are 19.5.

Check: There are two equal sides, so 19.5+19.5. Since the base is 6.5 inches bigger than either of the equal sides, the base is equal to 19.5+6.5=26. Adding these values all together comes out to 19.5+19.5+26=65.
