8x-11=2x-7+25
8x=2x+29
6x=29
divide by 6 on both sides
x=4.833333333

Answer 2

Answer:

x=4.833

Step-by-step explanation:

VH+HS=VS

VH=2x-7

VS=8x-11

HS=25

2x-7+25=8x-11

2x-2x-7+25=8x-2x-11

18=6x-11

18+11=6x-11+11

6x=29

x=4.833

x=20 is the solution to 4=x-16

Answers

Answer:

True

Step-by-step explanation:

So let's put this question into one equation.

x - 16 = 4 if x = 20

Well, this is a true statement. If we were to replace x with 20. We would see that the equation makes sense.

20 - 16 = 4

20 minus 16 does indeed equal 4.

Jack had $200 when he got to the festival. He spends $4 per ride. The equation T = 200 – 4R models his amount of money. If he has $100 left how many rides did he go on

Answers

Answer:

Step-by-step explanation:

Given the equation :

T = 200 - 4R

T = amount of money left ; if T = $100

R = number of rides

$100 = 200 - 4R

$100 - $200 = - 4R

-$100 = - 4R

R = 100/ 4

R = 25

25 rides

Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?

Answers

Answer:

The smaller number is 5

Step-by-step explanation:

Let the smaller number be x

the other number is (17 -x) (we know they add up to 17)

2/3 of the bigger number is written as 2/3 (17 - x)

The smaller number is 3 less than that. (so subtract 3 to get x)

x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x

Check 2/3 x 12 - 3 = 8 - 3 = 5

Step-by-step explanation:

Ok, so first, we are gonna make this an equation

Now, we will subtract 13 from 5

Now we have -3a=-8

Now, divide -8 by -3 and we get...

a=8/3

Set a equal to 5 then 3•5=15-13=2 the answer is two

Mina is saving up his money to buy a television that costs $400.25. Right now he has $115.00, and can save $31.00 each week.

How many weeks will it take for Mayato to have enough money to buy the television?

Answers

Answer:

Step-by-step explanation:

400.25 - 115.00 = 285.25

285.25/31 = 9.2016129....≈ 10 weeks

Answer:

10 weeks

Step-by-step explanation:

400.25 - 115 = 285.25

So he really only needs $285.25. So then we have to divide 285.25 ÷ 31 to find out how many weeks it will take to get to $285.25

285.25 ÷ 31 = 9.2

But you have to round it up to the nearest week. So the answer would be 10 weeks

Answer: (hopefully I didn't make a mistake :D )

y=-3+21

Step-by-step explanation: (I can't sketch the graph for you)

First you need to find the slope of the line passing through the points (5,4) and (-7,0). This can be done using the point-slope form of a line.

Point 1: (-7,0)

Point 2: (5,4)

y2-y1=m(x2-x1)

m= (y2-y1)/(x2-x1) = (4-0)/(5-(-7)) = 4/12= 1/3

Now, when two lines are perpendicular, they are negative recopricols. So the slope of the line would be -3.

Since the equation of the line you are trying to find passes through the point (4,9), using point-slope formula again and solve for y.

y-9=-3(x-4)

y= -3x+12+9

y=-3x+21

In ΔUVW, u = 5.8 inches, ∠W=77° and ∠U=87°. Find the length of v, to the nearest 10th of an inch.

Answers

Answer:

1.6

Step-by-step explanation

You can use the angles given to figure out the degree of the angles given and then with that you set up your equation as v divided by Sin(16) is equal to 5.8 divided by sin(87) and cross multiply.

After you cross multiply you should get approximately 1.5987 is equal to v times sin(87)

you then fin out the approximation of sin(87) which should be around 0.9986 and divide both sides by 0.9986 so v is alone and your answer comes out to be v = 1.6
