1/2d - 5 -1/4d = 10

Answers

d=60. multiply both sides of the equation by 4 since it’s a factor, giving you 2d-20-d=40. since there are like terms with d, collect them to get d-20=40 and move 20 to the right and change it’s sign. that will give you d=40+20, then calculate to get d=60. hope this helped! :)

37=-3+5(x+6), Please provide explanation.

Answers

Answer:

x=2

Step-by-step explanation:

youd distribute the 5 first so the equation is now

37=-3+5x+30

then group the common terms (-3 and 30 in this case)

37=5x+27

now subtract 27 from both sides to start to isolate 5x

10=5x

divide by 5 to find x

2=x

hope i helped :)

37=−3+5(x+6)
37 = -3 + (5)(x) + (5)(6)
37 = -3 + 5x + 30
37 = (5x) + (-3 + 30)
37 = 5x + 27
5x + 27 =37
5x + 27-27 = 37-27
5x= 10
Divide 5 on both side and you get x= 2

Taryn buys 8 identical glasses. Her total is $48 before tax. How much did Taryn pay for each pair of glasses?

Answers

Answer:

$12 per pair of glass.

$6 per glass.

Step-by-step explanation:

48/8 = 6

A pair is 2, so I multiplied 6 by 2.

6 x 2 = 12

So, Taryn paired $12 per glass.

ANSWER: $12 per pair

EXPLANATION: $48 divided by 8 pairs of glasses equals $6 per glasses. So then you multiply 6 by 2 to get the amount per pair.

A rectangular garden has a walkway around it. The area of the garden is 6(5.5x + 2.5). The
combined area of the garden and the walkway is 7.5(8x +4). Find the area of the walkway around
the garden as the sum of two terms.

Answers

Answer:The area of the walkway around is 26 x + 16 as the sum of two terms

Step-by-step explanation:

A rectangular garden has a walkway around it

1. The area of the garden is 4(4.5 x + 1.5)

2. The combined area of the garden and the walkway is 5.5(8 x + 4)

We need to find the area of the the walkway

To find the area of the walkway by subtracting the area of the

rectangle from the combined area

∵ The combined area = 5.5(8 x + 4) ⇒ simplify it

∴ The combined area = 5.5(8 x) + 5.5(4)

∴ The combined area = 44 x + 22

∵ The area of the garden = 4(4.5 x + 1.5) ⇒ simplify it

∴ The area of the garden = 4(4.5 x) + 4(1.5)

∴ The area of the garden = 18 x + 6

Now subtract the area of the garden from the combined area

∵ Area of the walkway = (44 x + 22) - (18 x + 6)

∴ Area of the walkway = 44x + 22 - 18 x - 6

- Add like terms

∴ Area of the walkway = (44 x - 18 x) + (22 - 6)

∴ Area of the walkway = 26 x + 16

The area of the walkway around is 26 x + 16 as the sum of two terms

bag contains 150 jelly beans. Toros reached into the bag 20 times and randomly selected one jelly bean. Each time, he recorded the color of the jelly bean, placed it back in the bag, and then mixed the jelly beans.

The following table represents the number of times Toros chose each color of jelly bean.
Based on these results, what is the probability that the next jelly bean Toros draws out of the bag will be yellow?

Answers

Ok so 150 total right? Divide that by 20 than multiply the picked up beans to find the probability of pulling a yellow jelly bean. That’s is 150/20=7.5 or 15/2. 3 (yellow jelly beans) is multiples by 7.5 which gives 15/100 chances of getting a yellow jelly bean in your next pull. Now simplify that, your welcome.

man I have no idea dude I don't really know squares if you're talking about square root I really don't know

Answer:

x = [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

This is not so fun!

[tex]4x^{2} + 8x - 5 = 0\\[/tex]

Step 1: Move the 5 to the right side

[tex]4x^{2} +8x = 5[/tex]

Step 2: Divide thru by 4

[tex]x^{2} + 2x = \frac{5}{4}[/tex]

Step 3: Divide 2 (from 2x) by 2 and square the result and add that to both sides of the equation.

2/2 = 1 1 squared = 1

[tex]x^{2} + 2x + 1 = \frac{5}{4} +1 = \frac{9}{4}[/tex]

Step 4: Factor the left side

[tex](x + 1)^{2} = \frac{9}{4}[/tex]

Step 5: Take the square root of both sides

x + 1 = ±[tex]\sqrt{\frac{9}{4} }[/tex] = ± [tex]\frac{3}{2}[/tex]

Step 6: Move the 1 to the right side and add the results

x = -1 ± [tex]\frac{3}{2}[/tex] = -1 + [tex]\frac{3}{2}[/tex] or -1 - [tex]\frac{3}{2}[/tex]

= [tex]\frac{1}{2}[/tex] or - [tex]\frac{5}{2}[/tex]

And bingo, you have the solutions by completing the square. Lot of fun, huh.

A long-distance delivery truck averages 8 miles per gallon when the truck is full. The
miles per gallon improves by 20% when the truck is empty. If the truck travels 160 miles
full to deliver its goods, and then travels back 160 miles empty, approximately how many
gallons will the truck use in all?

Answers

8 mpg when full
8*1.2=9.6mpg when empty
160/8+160/9.6=36.67

The gas used by truck is 36.66 mpg.

What is linear equation?

When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.

One-variable linear equations and two-variable linear equations exist.

Given

A long-distance delivery truck averages 8 miles per gallon when the truck is full.

The miles per gallon improve by 20% when the truck is empty.

The distance delivery truck averages 8 miles per gallon when full, and the amount of gasoline used (g) is expressed in terms of the number of miles driven ([tex]m_{f}[/tex]).

When the truck is full, the amount of gasoline is shown as,

[tex]m_{f}[/tex] = d/8

given distance is 160 miles

[tex]m_{f}[/tex] = 160/8 = 20 mpg

Then,

The miles per gallon improve by 20% when the truck is empty.

The number of miles driven when empty is represented as,

[tex]m_{e}[/tex] = d/(8 + 1.6)

[tex]m_{e}[/tex] = d/9.6

[tex]m_{e}[/tex] = 160/9.6

[tex]m_{e}[/tex] = 16.66 mpg

total gasoline required = [tex]m_{e}[/tex] + [tex]m_{f}[/tex] = 20 + 16.66 = 36.66 mpg

Hence the total gas used is 36.66 mpg.
