Answer:

D

Step-by-step explanation:

All real numbers are solution

Step 1: Simplify both sides of the inequality.

8x−7<8x−3

Step 2: Subtract 8x from both sides.

8x−7−8x<8x−3−8x

−7<−3

Step 3: Add 7 to both sides.

−7+7<−3+7

0<4

Answer:

The answer would be $87.20

Step-by-step explanation:

Because if it is 20 % off you would multiply it by 0.2 which would get you 21.8

Then, 109 - 21.8 is 87.20

Answer:

5.33 or 5[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Assuming you don't want the answer in decimals, this is the process to find the answer in fractions:

1 [tex]\frac{2}{5}[/tex] + (3 [tex]\frac{1}{3}[/tex] + [tex]\frac{3}{5}[/tex])

= [tex]\frac{7}{5}[/tex] + [tex]\frac{10}{3}[/tex] + [tex]\frac{3}{5}[/tex]  → convert into mixed fractions

= [tex]\frac{21}{15}[/tex] + [tex]\frac{50}{15}[/tex] + [tex]\frac{9}{15}[/tex] → find the least common denominator to make them the same

= [tex]\frac{80}{15}[/tex] = 5[tex]\frac{5}{15}[/tex] = 5[tex]\frac{1}{3}[/tex] → = add and simplify

Answer: 32

Step-by-step explanation:

If you divide 32 by 8 then you get 4

Answer:

she ran 10 miles a hour

Step-by-step explanation:

she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10

Heather's rate of speed last week was 1/12 miles/min.

Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.

Heather's rate of speed last week -

{r} = 4/48 = 1/12 miles/min

{r} = 1/12 miles/min

Therefore, Heather's rate of speed last week was 1/12 miles/min.

Answer:

[tex]n+d\leq 20[/tex]

If Connor buys 3 snacks at 3 dollars each for himself and his 3 children, the net cost (including movie tickets) would be 88 dollars.

If he buys x amount of snacks, his cost will be determined by C=52+3x or C=52+3*x (both are equivalent, but not everyone knows every way to represent multiplication)

Step-by-step explanation:

To find the cost of the snacks:

Cost = Price*NumberOfSnacks, or C=p*n, or C=pn

To find the unit cost of the snack, find the price, the p value, which is 3 dollars.

Then, find the total number of snacks that will be bought. Since each person receives an equal number of snacks, 3 per person, and there are 4 people (himself and his 3 children), we can multiply 3*4 to find the n value, which is now known to be 12.

C=3*12=36. Add to the 13 dollar per person charge for tickets (52 dollars for 4 people), and you get 88 dollars.

To find the cost if he buys x amount of snacks for himself and his 3 children (assumed to be "everyone"), all costs but the n value are to be the same, creating this equation:

C=52+3x

In this context, 52 is the cost of movie tickets, 3 is the cost of the snacks, and x is the total number of snacks bought. C represents total cost.

The total cost for tickets and 5 snacks is $90.

The total cost for tickets and x snacks is $(65+5x).

Important information:

The total number of people is 5. So, cost of 5 tickets is:

[tex]5\times 13=65[/tex]

Cost of 5 snacks is:

[tex]5\times 5=25[/tex]

Total cost is:

[tex]65+25=90[/tex]

The total cost for tickets and 5 snacks is $90.

Cost of x snacks is:

[tex]5\times x=5x[/tex]

Total cost is:

[tex]65+5x[/tex]

The total cost for tickets and x snacks is $(65+5x).

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50

7.50 - 3= $4.50

9.00+7.47+4.50= $20.97

Answer:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Step-by-step explanation:

Given the expression

[tex]-6\:-\:7\:\left(c+10\right)[/tex]

simplifying the expression

[tex]-6-7\left(c+10\right)[/tex]

Expanding -7(c + 10) = -7c - 70

[tex]-6\:-\:7\:\left(c+10\right)=-6-7c-70[/tex]

subtract the numbers: -6 - 70 = -76

                           [tex]=-7c-76[/tex]

Therefore, we conclude that:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

the top angle is obtuse and the lower corner is acute, im not sure about the relationship though good luck!❤

Answer:

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true

hope this makes sense and hope it helps :)

Answer:

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2
