Answer:

2 11/14

Step-by-step explanation:

First make both of them improper fractions.

therefore,

2 4/7 = 18/7

now simplify.

18/7 × 13/12

18 and 12 get cancelled off as they're multiples of 3 and 6

therefore,

3/7 × 13/2

3× 13 = 39

7×2 = 14

39/14

now make it a proper fraction

2 11/14//

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+4x−68=34−8x

5x+4x+ −68=34+ −8x

(5x+4x)+(−68)=−8x+34(Combine like terms)

9x+−68=−8x+34

9x−68=−8x+34

Step 2: Add 8x to both sides.

9x −68+ 8x= −8x +34 +8x

17x −68 =34

Step 3: Add 68 to both sides.

17x −68 +68= 34 +68

17x=102

Step 4: Divide both sides by 17.

17x /17=  102/17

                                X=6   > final answer hope i could help :)

Step-by-step explanation:

Let's step through this line by line, looking for a spot where the friend could have made a mistake.

[tex]5x+4x-68=34-8x\\5x+4x=102-8x\\5x+4x+8x=102\\17x=102\\x=6[/tex]

So, where could the friend have made their mistake? The key here is the transition from step 1 to step 2. What if we had subtracted 68 instead of adding it?

[tex]5x+4x-68=34-8x\\5x+4x=-34-8x\\5x+4x+8x=-34\\17x=-34\\x=-2[/tex]

There it is. The friend's problem was that they had accidentally subtracted 68 to both sides when they should have added it.

Answer:

Find the corresponding y-value to x=−3.

Substitute −3 in for x.

y=−4(−3)²+8(−3)+8

Simplify −4(−3)²+8(−3)+8

y=−36−24+8 => y=−52

Find the first derivative and evaluate at x=−3 and y=−52 to find the slope of the tangent line.

Plug the slope and point values into the point-slope formula and solve for y

y=32x+44

Answer:

396 cm²

Step-by-step explanation:

This may look complex, but it's actually an easy one.

The length of the left hand side is 27 cm, while the length of the right hand side is 9 cm. Subtracting 9 from 27, we have 18 cm

Also, the breadth of the bottom is 24 cm, while the breadth of the top is 10 cm. Subtracting 10 from 24, we have 14 cm.

Now, to find the area, we divide the diagram into 2. Taking the breadth first, we have breadth of 24 cm and it's relatively small height of 9 am.

Area of a rectangle is l * b, = 24 * 9 = 216 cm

Now, we look at the remaining part of the diagram. The length with a height of 18 cm, and a breadth of 10 cm. Area of a rectangle is l * b, = 180 cm

Adding both calculations together, we have 180 + 216 = 396 cm²

Step-by-step explanation:

65% of 80 is

65*80/100=52

Answer:

52

Step-by-step explanation:

Calculate percentage:

'Percentage' is obtained by multiplying 80 by 65%.

65% × 80 =

(65 ÷ 100) × 80 =

(65 × 80) ÷ 100 =

5,200 ÷ 100 =

52

Checking:

How do we check the result?

If 65% × 80 = 52 =>

Divide 52 by 80...

... And see if we get as a result: 65%.

Calculate the percent value:

52 ÷ 80 =

0.65 =

0.65 × 100/100 =

(0.65 × 100)/100 =

65/100 =

65%

Answer:

Train A is 287 tons

Train B is 94 tons

Step-by-step explanation:

My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.

Answer:

(c). Angle 12 and 9

Step-by-step explanation:

(-5, -1) is not a solution to the equation 2y = 2x - 4.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

2y = 2x - 4 _____(1)

Ordered pair: (-5, -1)

Now,

(-5, -1) = (x, y)

Substitute in (1)

2y = 2x - 4

2 x (-1) = 2 x (-5) - 4

-2 = -10 - 4

-2 = -14

This is not true.

Thus,

(-5, -1) is not a solution.
