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.

if you could anwser the second question that would be great caus e i only get to do this proble once :) no explanation needed

Angle 1 and 2 are equal because of correspondence angle

so , (78-2x) = (89-3x)

x = 89 - 78

x = 11

hence angle 1 = ( 78 - 2*11) = 56

and angle 2 = ( 89-3*11) = 56

So, both of angle is 56

hope it help and your day will full of happiness

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:

10

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

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

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

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
