Solve the equation for the given variable.
5- 3x = 4

Answer:

40 and 28

Step-by-step explanation:

We have two unknown numbers, so let's call them x and y for now.

We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:

x+y=68

and

x-y=12

Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.

So we have:

(x+y)+(x-y)=(68)+(12)

2x=80

x=40

Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.

After plugging in x, we get:

40-y=12

-y=-28

y=28

So now we have figured out x and y, which are 40 and 28.

Answer:

Step-by-step explanation:

Let x=smaller number

Then x+5=larger number

Now we are told the following:

1/5(x+x+5)=x-5 multiply each side by 5

x+x+5=5x-25 subtract 5x and also 5 from both sides

x+x+5-5-5x=5x-5x-25-5 collect like terms

-3x=-30 divide both sides by -3

x=10-----------------------smaller number

x+5=10+5=15 ---------larger number

Answer:

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of B

To find the value of B we use cosine

That's

cos∅ = adjacent / hypotenuse

From the question

adjacent = 4

hypotenuse = 5

We have

[tex] \cos(B) = \frac{4}{5} \\ B = { \cos }^{ - 1} ( \frac{4}{5}) \\ = 36.869897645...[/tex]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Starting point = 18 inches

Rate or speed = 3 inch per minute

t = number of minutes since climbing began

When will worm be more than 60 inches above the ground.

Height (t) = starting point + (rate * time)

18 + 3t > 60

3t > 60 - 18

3t > 42

t > 42/3

t > 14

Hence, inequality to use is : 60 > 18 + 3t

Answer:

x=[tex]\frac{m}{k-n}[/tex]

Step-by-step explanation:

First you subtract nx from both side getting kx-nx=m.

Then you factor out x getting x(k-n)=m

and now you divide both sides from (k-n) and you will get the answer.

y=1x+1

Step-by-step explanation:

y=1x+1 gradient= 1 and y-intersept = 1

Answer:

Step-by-step explanation:

Using slope formula and solving for y

m = (y2 - y1)/(x2 - x1)

Answer:

y = 2

Step-by-step explanation:

Using slope formula and solving for y

m = (y2 - y1)/(x2 - x1)

-2/7 = (4 - y)/(3 - 10)

-2/7 = (4 - y)/-7

2 = 4 - y

y = 4 - 2

y = 2

Answer: 6.5 cm

Step-by-step explanation: 1 km = 100,000 cm, so 130 km= 130,000,00 cm, 130,000,00÷2,000,000=6.5 cm

The Charles river will be "6.5 cm" long. A complete solution is provided below.

On the map,

→ 1 : 2,000,000

As we know,

The conversion of kilometer in to centimeter is:

→ [tex]1 \ km = 100,000 \ cm[/tex]

then,

→ [tex]130 \ km= 130,000,00 \ cm[/tex]

hence,

The river will be:

= [tex]\frac{130,000,00}{2,000,000}[/tex]

= [tex]6.5 \ cm[/tex]

Thus the above answer is the appropriate.

Answer:

157.5 pages

Step-by-step explanation:

First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:

2m = 7

---      ---      <---- Here we divide both sides of the equal sign by 2

2        2

m = 3.5 <---- we read 3.5 pages per minute

45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.

Answer: D(2750) = 637.5

if total sales = $2750 then total donation = $637.5

Step-by-step explanation:

GIven: A local coffee shop has made a flat donation of $500 and also give a percent of their total sales over a specified weekend.

The total donation can be modeled by the function rule D(s)=500+0.05s,

where s = total sales at the coffee shop during the fundraising weekend in dollars.

Now, D(2750) = 500+0.05(2750)

= 500+ 137.5

= 637.5

i.e. if total sales = $2750 then total donation = $637.5
