Answer:

80%

Step-by-step explanation:

4 divided by 5 = 0.8

0.8 x 100 = 80%

The percentage Larry ran around the track = 80%  

He ran 4/5 of the way around the track before slowing down for a walk.

This means he ran 4 parts of the whole 5 parts of the track. He walks the remaining 1 part around the track.

Therefore, the percentage he ran can be calculated below

% he ran the track = 4 / 5 of 100

% he ran the track = 4 / 5 × 100 = 400 / 5 =  80%

The percentage he ran around the track  = 80%

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 8(4 + 3x) = - 200}[/tex]

Distribute -8 through the parentheses

[tex] \longrightarrow{ \sf{ - 32 - 24x = - 200}}[/tex]

Move 32 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{ - 24x = - 200 + 32}}[/tex]

The negative and positive integers are always subtracted but posses the sign of bigger integer

[tex] \longrightarrow{ \sf{ - 24x = - 168}}[/tex]

Divide both sides by -24

[tex] \longrightarrow{ \sf{ \frac{ - 24x}{ - 24} = \frac{ - 168}{ - 24}}} [/tex]

Calculate

Answer:

If she bought 2lbs of almonds, she bought 0.4lbs of raisins. If she bought  1lb of almonds, she can buy up to 2.36lbs of raisins. If she bought 0.64lbs of almonds, she can buy up to 1.9lbs of almonds.

Step-by-step explanation:

The total pounds of raisins bought  is 0.47 pounds.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that Priya bought 0.47 pounds of raisins, Almonds cost is $5.20 per pound and Raisins cost $2.75 per pound.

The Total cost of almonds purchased = $5.20a

The Total cost of raisins purchased = $2.75r

Where:

a = total pounds of almonds bought

r = total pounds of raisins bought

The Total amount spent on raisins and almonds;  

5.20a +2.75r = 11.70

If 2 pounds of almonds are bought;

5.20(2) +2.75r = 11.70.

10.40 + 2.75r = 11.70

Combine similar terms;

2.75r = 11.70 - 10.40

2.75r = 1.30

Now Divide both sides of the equation by 2.75

r = 0.47 pounds

Hence, the total pounds of raisins bought  is 0.47 pounds.

Answer:

- 340

Step-by-step explanation:

The sum to n terms of an AP is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] ( a + l ) → a is the first term and l the last term

Here a = - 76 and [tex]S_{45}[/tex] = - 9360 , thus

[tex]\frac{45}{2}[/tex] ( - 76 + l ) = - 9360

22.5(- 76 + l) = - 9360 ( divide both sides by 22.5 )

- 76 + l = - 416 ( add 76 to both sides )

l = - 340 ← the last term in the sequence

Answer:

F= -103/-4d^4+d

Step-by-step explanation:

fd=4d2dfd−2−101

Step 1: Add -4d^4f to both sides.

df+−4d4f=4d4f−103+−4d4f

−4d4f+df=−103

Step 2: Factor out variable f.

f(−4d4+d)=−103

Step 3: Divide both sides by -4d^4+d.

f(−4d4+d)

−4d4+d

75% = 0.75

750 people / 0.75 = 1,000 people

There were 1,000 total people attending the game

Answer:

1,000 people

Step-by-step explanation:

At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, the total number of people attending the game was 1,000 people.

75% = 3/4 or 0.75

25% = 1/4 or 0.25

We need to find what 25% is.

75/3=25

75% = 0.75

750 people / 0.75 = 1,000 people

Therefore, there were 1,000 people at the game.

Answer:

11k -1

Step-by-step explanation:

- k + 3(4k - 1) + 2

-k +12k - 3 +2

11k -1

Step-by-step explanation:

We need to find the value of x for all problems if Y is between X and Z.

For all cases, XZ = XY+YZ

4. XY = 5x, YZ=x, and XZ=25

Putting all values

25 = 5x + x

25 = 6x

[tex]x=\dfrac{25}{6}[/tex]

5. XY = 12, YZ=2x, and XZ = 28

28 = 12 + 2x

x = 8

6.  XY = 4x. YZ=3x, and XZ = 42

XZ = XY+YZ

42 = 4x + 3x

42 = 7x

x = 6

7. XY=2x + 1. YZ = 6x, and XZ=81

XZ = XY+YZ

81 = 2x + 1 + 6x

80 = 8x

x = 10
