Answer:

m=10

w=15

Step-by-step explanation:

m + w = 25

3m + 4w = 90

Let's do substitution, first by solving the first equation for m.

m = 25 - w

Substitute!

3(25 - w) + 4w = 90

75 - 3w + 4w = 90

w = 15

m = 25 - 15 = 10

Step-by-step explanation:

3(x-1) -5(x-4) = 8

3x-3 -5x+20 = 8

3x -5x -3 +20 = 8

-2x + 17 = 8

17 -8 = 2x

9 = 2x

2x = 9

x = 9/2

Answer:

-400

Step-by-step explanation:

So, to find what the depth would be in 8 minutes, you have to find the depth for ONE minute. So, you divide -100 by 2 and you get -50 in a minute. Next thing you do is you multiply -50 by 8. You get -400. And there's your answer!

Answer:

x = 22

Step-by-step explanation:

rearange the equation to 25-3=x. 25-3 = 22, therefore x = 22

Answer: X =22

Step-by-step explanation: Switch sides x + 3= 25 then subtract 3 from both sides x + 3 - 3= 25-3 then simplify and you get X=22

Answer: Paula starts with 301.5 yarns.

Step-by-step explanation:

Equation of a line passing through two points (a,b) and (c,d) is given by:-

[tex](y-b)=\dfrac{b-d}{a-c}(x-a)[/tex]

Given: x=  number of square inches knitted on the scarf

y= number of yarns remaining on the ball of yarn

The equation of a line passing through (15, 300.2) and (26, 177.88):

[tex](y-300.2)=\dfrac{26-15}{177.88-300.2}(x-15)\\\\\Rightarrow (y-300.2)=\dfrac{11}{-122.32}(x-15)\\\\\Rightarrow (y-300.2)=\dfrac{11}{-122.32}(x-15)[/tex]

To find initial point, put x=0

[tex]y-300.2=-\dfrac{11}{122.32}(0-15)\\\\\Rightarrow\ y-300.2=\dfrac{375}{278}\\\\\Rightarrow\ y=\dfrac{375}{278}+300.2\\\\\Rightatrrow\ y=301.5 \ \ (approx)[/tex]

Hence, Paula starts with 301.5 yarns.

The equation that can be used to find d, the diameter of the tunnel opening, is: d = 42/π

What is circumference ?

The circumference is the distance around the outer edge of a closed, circular object such as a circle or a sphere. It is the length of the boundary of the circle or sphere, and is usually measured in units of length, such as centimeters, meters, or feet.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this problem, we are given the circumference of the tunnel opening, which is 42 meters. We want to find the diameter of the tunnel opening, which is twice the radius. Therefore, we can use the following equation:

C = 2πr = πd

where d is the diameter of the tunnel opening.

We can rearrange this equation to solve for d:

d = C/π

Substituting the value of C = 42 meters, we get:

d = 42/π meters

Therefore, the equation that can be used to find d, the diameter of the tunnel opening, is: d = 42/π

Answer: The average change in field position on each run was [tex]1\frac34[/tex] yards.

Step-by-step explanation:

Given: Total loss of field = [tex]8\dfrac34[/tex] yards  = [tex]\dfrac{35}{5}\text{ yards}[/tex]

Number of times football team carried the ball  = 5

The average change in field position on each run =  [tex]\dfrac{\frac{35}{4}}{5}[/tex]

Answer:

X=7

Step-by-step explanation:

10+4x=5(x-6)+33

1. Distribute the 5 to both the x and the 6

10+4x=5x-30+33

2. Subtract 4x from 5x ( should be left with 1x but just write x)

10=x-30+33

3. add 30 to both sides (whole number on the left, x on the right)

40=x+33

4. Subtract 33 on both sides

7=x (flip it around)

x=7

Answer: 12a+ 13b

Step-by-step explanation:

Answer:

12a+13b

Step-by-step explanation:

The expression cannot be further simplified as there are no like terms.

Given:

In rhombus RSTU, [tex]m\angle RUV=(10x-23)^\circ[/tex] and [tex]m\angle TUV=(3x+19)^\circ[/tex].

To find:

The [tex]m\angle RST[/tex].

Solution:

We know that, diagonals of a rhombus are angle bisector. So,

[tex]m\angle RUV=m\angle TUV[/tex]

[tex](10x-23)^\circ=(3x+19)^\circ[/tex]

[tex]10x-23=3x+19[/tex]

Isolating variable terms, we get

[tex]10x-3x=23+19[/tex]

[tex]7x=42[/tex]

Divide both sides by 7.

[tex]x=\dfrac{42}{7}[/tex]

[tex]x=6[/tex]

Now,

[tex]m\angle RUV=(10x-23)^\circ[/tex]

[tex]m\angle RUV=(10(6)-23)^\circ[/tex]

[tex]m\angle RUV=(60-23)^\circ[/tex]

[tex]m\angle RUV=37^\circ[/tex]

And,

[tex]m\angle TUV=(3x+19)^\circ[/tex].

[tex]m\angle TUV=(3(6)+19)^\circ[/tex]

[tex]m\angle TUV=(18+19)^\circ[/tex]

[tex]m\angle TUV=37^\circ[/tex]

Now,

[tex]m\angle RUT=m\angle RUV+m\angle TUV[/tex]

[tex]m\angle RUT=37^\circ+37^\circ[/tex]

[tex]m\angle RUT=74^\circ[/tex]

We know that opposite angles of a rhombus are equal.

[tex]m\angle RST=m\angle RUT[/tex]

[tex]m\angle RST=74^\circ[/tex]

Therefore, the measure of angle RST is [tex]74^\circ[/tex].
