Answer:

3m + 13 = 31 I hope this helps you!

Answer:

1st number = 4

2nd number = -1

Step-by-step explanation:

Let n = 1st number

Let m = 2nd number

2n + 4m = 4

n - m = 5

Substitu method, let n = 5 + m

2(5+m) + 4m = 4

10 + 2m + 4m = 4

6m = -6

m = -1

find n:

n - (-1) = 5

n + 1 = 5

n = 4

Answer:

Slope = -5/4.    And y-int = (0,-1)

Step-by-step explanation:

Answer:

i think its -5

Step-by-step explanation:

if you devide 25 by -5 you get -5

Answer: x = -5

Step-by-step explanation:

We can use inverse operations to solve the equation. Because the term "-5x" is multiplication (because you are multiplying x by -5), we can use division to solve the equation.

First, we will divide -5 from 25.

25 ÷ -5 = -5.

Because of this, x = -5!

If we're not sure, we can also check the equation.

-5 x -5 = 25, so the answer is true.

In conclusion, x = -5!

Answer:

J (3; 9)

Step-by-step explanation:

Imagine each distance like a triangle and use Pythagorean theorem.

To illustrate I drew triangle ΔLON in the picture

Finding the distance between LN.

LO = [tex]y_{L} - y_{O}[/tex] = 5 - 1 = 4

NO = [tex]x_{N} - x_{O}[/tex] = 5 - 4 = 1

According to Pythagorean theorem

[tex]LN^{2} = LO^{2} + NO^{2}[/tex]

[tex]LN^{2}[/tex] = [tex]4^{2} + 1^{2}[/tex] = 17

LN  = [tex]\sqrt{17}[/tex] (LN > 0)

Since ΔMLN ≅ ΔKLJ, JL = LN (they are clearly equal triangles)

Mark J coordinates as (x; y)

Draw another triangle JOL, ∠JOL = 90°)

OJ is parallel with x axis and OL is parallel with y axis.  O coordinates then are (4; y)

OL  = y - 5

OJ = 4 - x

Note that ΔLON = ΔJOL, so OL is the same as LO and therefore

OL = LO = y - 5 = 4;

y = 9

OJ = NO = 4 - x = 1

x = 3

So the coordinates of J are (3; 9)

Similarly find the coordinates of K

So what I'm thinking right. If it costs my pal bob $0.25 for each cupcake and an additional $15 per month we will probably need to variables. So check it

Our positive when we make money is when bob sells cupcakes right? but our negative where bob is spending his money is the $0.25 it cost per cupcake and the $15 a month he also has to pay for expenses

$1.50c-$0.25c-$15.00m

c represents the amount of cupcakes while m represents each month

So if Buddy Boy Bob sold 85 cupcakes in one month lets try to use our equation to solve for profit shall we.  

$1.5(85)-$0.25(85)-$15(1)= Bob made about $91.25

Answer:

$10

Step-by-step explanation:

Since 6 cost four dollars 3 would cost 2 dollars multiply 3 to get 15 bananas and 2 to get $10

Answer:

$10

Step-by-step explanation:

Make proportion:

?= cost  of bananas

6  -  4

15  -  ?

?= 15×4÷6=10

Answer: How find the volume of a triangular pyramid?

Triangular pyramid volume formula

In words: the volume of a triangular pyramid is one-third of the product of the base area and the pyramid's height

Step-by-step explanation:

Now in mathematical terms Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.

Best of Luck!

Answer:

there monthly budget is $4000

Step-by-step explanation:

if 600 is 15% then there is 85% of there budget left so in order to find how much is 1% then 600/15=40 so $40 = 1% so 1%x100=100%  and 40x100=4000 so 100% of there budget is $4000

hope this helps have a blessed day :)

Answer: 24 inches.

Step-by-step explanation:

If each section length is 4 inches, then that means that each person will need to eat a sandwich section that is at least 4 inches.

There are 6 people, which means that each person will eat 4 inches of a sandwich.

To calculate the length of the sandwich Riko should order, we should mutliply 6 by 4, because there are 6 people and each person will be eating 4 inches of a sandwich.

6 x 4 = 24.

In conclusion, the smallest sandwich Riko should order is a sandwich that is 24 inches long.

(Quick Note: This is also the smallest sandwich Riko could order, because the text states that each person eats at least 4 inches.)

Answer:

y = 9x

Step-by-step explanation:

Answer: The fraction of the original allowance does she plan to save = [tex]\dfrac16[/tex]

Step-by-step explanation:

Let x = original monthly allowance

Monthly allowance left = [tex]\dfrac23x[/tex]

She plans to save = [tex]\dfrac14[/tex] of (Monthly allowance left)

= [tex]\dfrac14\times\dfrac23x[/tex]

[tex]=\dfrac{2}{12}x\\\\=\dfrac{1}{6}x[/tex]

i.e. the fraction of the original allowance does she plan to save = [tex]\dfrac16[/tex]

y=4x+3

Step-by-step explanation:

find the slope using y2-y1/x2-x1

simplify

8/2

simplify

4

find b by using the equation y=mx+b

since we know 4 is the slope, plug it in for m

plug an ordered pair into y=4x+b

3=4(0)+b

3=b

plug b in y=4x+b

y=4x+3

Answer:

Option 1 = 3/2

Step-by-step explanation:

The rise = 3

The run = 2

Answer:

Given that angle APB = 100°

Angle CPB = 180°- 100°. (Angle APB and CPB form a linear pair)

We know all triangles formed here are isosceles

Therefore,

We can take angle PBC= angle PCB = x

Now,

Angle CPB+ x + x = 180°. ( Triangle sum property)

100° + 2x = 180°

2x = 180°- 100°

2x= 80°

x= 80°/2

x= 40°
