x=5 and 2 x+y=10 what is x and y?

Answers

Answer 1
since you are given x then x=5
now you plug in x into the equation which is
2(5)+y=10
which equals to 10+y=10
minus 10 on both sides to get y by itself
y=10-10
y=0
Answer 2
Y=0 y+2(5)=10 y+10=10 minus 10 away on both sides

Answer:

y = 2/3x - 20

Step-by-step explanation:

The fraction in front of the X determines the slope

y = 2/3x - 20 has a slope of 2/3

y = 1/3x + 100 has a slope of 1/3

y = 2/5x + 2 has a slope of 2/5

y = 4/12x has a slope of 4/12

Y = 2/3 -20 has the biggest slope

Workers are loading boxes onto a truck. So far, they have loaded 48 boxes onto the truck.
According to their inventory, they still need to load 96% of the boxes on the truck. How many boxes do they need to load on th
Let b = the number of boxes the workers need to load on the truck.

Answers

48=4% loaded on truck and they have 96% left to load
So set up a proportion and it should look like this
48 over x = 4 over 100
48/x=4/100
Do cross multiplication 100×48= 4,800÷ 4 = 1,200 total on truck

pls help trigonometry is confusing to me :(

Answers

My first tip would be to label your triangles.

If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.

The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.

If you find the right angle and go across, that would be our hypotenuse.

//

In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.

[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]

[tex] \tan(43) = \frac{x}{40} [/tex]

if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.

Since x is on the numerator, we would have to multiply.

[tex]x = 40 \tan(43 ) [/tex]

[tex]x = 37.3006034455[/tex]

[tex]x = 37.30[/tex]

Write the equation of the line in slope-intercept form with slope = 1/4 and point (-8, 6)

Answers

Step-by-step explanation:

This is the standard linear equation:

[tex]y=mx+b[/tex]

[tex]m[/tex] represents slope and [tex]b[/tex] represents the y-intercept. In a finished equation, [tex]x[/tex] and [tex]y[/tex] are left as variables. [tex]x[/tex] and [tex]y[/tex] represent any given point in the function. In this case, one of the given coordinates is [tex](-8, 6)[/tex], and we can use this by using [tex]-8[/tex] as [tex]x[/tex] and [tex]6[/tex] as [tex]y[/tex]. After plugging in known variable, the equation becomes this:

[tex]6 = \frac{1}{4} ( - 8) + b[/tex]

This simplifies to:

[tex]6 = - 2 + b[/tex]

Then to:

[tex]4=b[/tex].

After plugging in slope and y-intercept, the finished equation is:

[tex]y = \frac{1}{4} x + 4[/tex]

. Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?

Answers

This question is incomplete

Complete Question

A school held several evening activities last month—a music concert, a basketball game, a drama play, and literacy night. The music concert was attended by 250 people. How many people came to each of the other activities?

Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?

Answer:

350 people

Step-by-step explanation:

Percentage of people that attended a drama play =

Number of people that attended the drama play/Total number of people at the concert × 100

Attendance at the drama play was 140% of attendance at the concert.

The music concert was attended by 250 people

Let the number of people that came to the drama play = x

Hence:

140% = x/250 × 100

140/100 = x/250

Cross Multiply

140 × 250 = 100 × x

x = 140 × 250/100

x = 350 people

Therefore, the number of people that came to the drama play = 350 people

The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]

Determine the value of f, rounded to the nearest hundredth.

Answers

Answer:

0.35

the next one is d(v) = 2.15v^2 / 22.54

Step-by-step explanation:

i just did this assignment. also thanks to the answer above me :)

We have that the value of f, rounded to the nearest hundredth.

f_1=0.02

f_2=0.009

f_3=0.009

From the question we are told that

d(v)= \frac{2.15v^2}{64.4f}

Generally the equation for the f is mathematically given as

f= \frac{2.15v^2}{64.4*d(v)}

Therefore

For v=20 and f=38

f= \frac{2.15(20)^2}{64.4*(38)(20)}

f=0.02

For v=30 and f=86

f=\frac{2.15(30)^2}{64.4*(86)(30)}

f=0.01

For v=40 and f=153

f=\frac{2.15(40)^2}{64.4*(153)(40)}

f=0.009

25, 0, -18, 5, -12

-12, 25, 5, 0, -18

5, -18, 25, -12, 0

Step-by-step explanation:

The only values you need to use here are 0, 5, 25, -12, and -18.

I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.

Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.

After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.

Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.


Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.​

Answers

Answer:

After 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Step-by-step explanation:

Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:

X = 2,500 x (1 + 0.03 / 1) ^ 4

X = (2,500 x 1,003) ^ 4

X = 2,813.77

Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.
