a. The sum of two numbers is 22 and their difference is 14.

i. Form the simultaneous equations.




ii. Find the two numbers.

The price for the text message that is charged by the cellphone company will be $0.2.

Based on the above, the equation to represent the information given will be:

m + 104n = 50.79 ....... equation i

m + 83n = 46.59 ......... equation ii

Subtract equation ii from i

21n = $4.2

Divide both side by 21

21n/21 = $4.2/21

n = $0.2

Answer:

x= plus or minus square root of 19 -4

Step-by-step explanation:

x^2+8x ___=3

take half of your b term (8) and then multiply by two and add or subtract it to both sides

x^2+8x+16=3+16

then combine like terms

x^2+8x+16=19

then factor your quadratic equation

(x+4)^2=19

now solve for x

take the square root of (x+4)^2 to get rid of the ^2

you then also have to square the 19 because what you do to one side you have to do to the other

(x+4)= square root of 19

subtract 4 from both sides

x= plus or minus square root of 19 -4

Answer:

Step-by-step explanation:

Divide the coefficient of x by 2

8/2 = 4. Now find the square of 4 = 4² = 16

Add 16 to both sides of the equation

x² + 8x + 16 = 3  + 16

x² + 2* x * 4 + 4² = 19

{Compare with a² + 2ab + b² = (a + b)² }

(x + 4)² = 19

Both sides take square root,

[tex]\sqrt{(x+ 4)^{2}}=\sqrt{19}\\\\x + 4 = \sqrt{19}[/tex]

x + 4 = ± 4.36

x + 4 = 4.36   ; x +  4 = -4.36

x = 4.36 -4     ;    x  = -4.36 - 4

x = 0.36         ; x = - 8.36

Answer:

1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Step-by-step explanation:

Ikr the bots are annoying.

Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]

Slope intercept form is written as: [tex]y=mx+b[/tex]

We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

1) Points given are (1,6) and (-2,8)

Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]

You can choose either of the two points to put into the formula. I just chose (1,6)

Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]

2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.

[tex]6=-\frac{2}{3} (1)+b[/tex]

[tex]6=-\frac{2}{3} +b[/tex]

[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]

[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]

Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Answer:

19xyz

Step-by-step explanation:

First, let us just forget about the xyz at the end of each number. Now, we just have the simple addition problem 3 + 7 + 9. First. let us do 3 + 7, which gives us 10. Now, let us take our 10 and add the 9 to it. 10 + 9 is 19. Now, we can add our xyz back to the equation. Now, we have 19xyz. As we do not know anything about what x, y, or z equals, nothing further can be done with this equation. Therefore, the answer is 19xyz.

Hope this helps! :D

Step-by-step explanation:

We are required to find the equivalent fraction of the family’s budget that is spent on housing

fraction of the family’s budget that is spent on housing is 7/25

let

Total budget of the family = x

Monthly housing budget = 28%

percentage monthly housing budget = 28% of x

= 28/100 × x

= 0.28x

Fraction of the family’s budget that is spent on housing = 28/100 × x

= 7/25 × x

= 7/25x

Therefore, fraction of the family’s budget that is spent on housing is 7/25

The currency called the dollar can be divided or reduced into smaller forms also known as pennies, quarters, nickels and dimes.

The number of pennies is 5, the number of dimes is 5, the number of quarters is 30.

It is important to note that

a penny = $0.01

a dime = $0.10

a quarter = $0.25

Let's represent the number of

pennies = p

dimes = d

quarters = q

The number of pennies is equal to the  number of dimes, hence:

p = q, so we can represent the number of pennies and dimes as y

The box currently  contains 40 coins

So: 40 = y + y + q

q = 40 - 2y...........Equation 1

The total value of the coins is $8.05

So: 0.01y + 0.1y + 0.25q = 8.05 ........... Equation 2

We substitute 40 - 2y for q in Equation 2

0.01y + 0.1y + 0.25(40 - 2y) = 8.05

0.01y + 0.1y + 10 - 0.5y = 8.05

Collect like terms

0.01y + 0.1y - 0.5y = 8.05 - 10

-0.39y = -1.95

Divide both sides by -0.39

-0.39y/-0.39 = -1.95/0.39

y = 5

Since y represents the number of pennies and dimes,  the number of pennies is 5 and the number of quarters is 5.

To solve for the number quarters, we would use equation 1

q = 40 - 2y...........Equation 1

q = 40 - 2 x 5

q = 40 - 10

q = 30

The number of quarters is 30.

Therefore, we have 5 pennies, 5 dimes, and 30 quarters.
