9. Which is a solution of the equation 5(x – 8) = -55 ?
a) x = 3
b) x = 13
c) x = -3
d) x = -9.4

Step-by-step explanation:

122 - 25

97

y= 8.5x + 25

97/8.50 <

11.4 --> 12

x < 12

Answer:

25 + 8.50w ≥ 122

Step-by-step explanation:

Given that:

Amount saved per week = $8.50

Cost of phone = $122

Starting amount = $25

Minimum Number of whole weeks (w) Sébastien will need to save :

Starting amount + (weekly saving * number of weeks) ≥ 122

25 + 8.50w ≥ 122

8.50w ≥ 122 - 25

8.50w ≥ 97

w ≥ 97/8.50

w ≥ 11.4117

Number of whole weeks = 12

Answer:

y = 4x

Bowl 6 games cost $24

Step-by-step explanation:

Proportional Relationship

We have a situation where the cost y in dollars to spend an evening bowling is proportional to the number of games x bowled.

A proportional relationship is written with the equation:

y = k.x

The value of k will be determined by using the given information: 4 games bowled cost $16, thus:

16 = k.(4) = 4k

Solving:

k = 16 / 4 =4

Thus, the function is:

y = 4x

x=6 games bowled cost:

y = 4*6

y = $24

Bowl 6 games cost $24

Answer:

[tex]\boxed {x < -4}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]7(x + 3) < 5x + 13[/tex]

Use Distributive Property:

[tex]7(x + 3) < 5x + 13[/tex]

[tex]7x + 21 < 5x + 13[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]7x[/tex]:

[tex]7x + 21 - 5x < 5x - 5x + 13[/tex]

[tex]2x + 21 < 13[/tex]

Subtract both sides by [tex]21[/tex]:

[tex]2x + 21 - 21 < 13 - 21[/tex]

[tex]2x < -8[/tex]

Divide both side by [tex]2x[/tex]

[tex]\frac{2x}{2} < \frac{-8}{2}[/tex]

[tex]\boxed {x < -4}[/tex]

Answer:

I don't understand what to do

Answer:

y = [tex]\frac{-2x}{3}[/tex]

Step-by-step explanation:

Distribute 5 to 2x and 3y by multiplying each by 5

10x + 15y

Isolate y to one side of the equation

15y=-10x

Divide each side by 15

y = [tex]\frac{-2x}{3}[/tex]

Answer:

5(2x + 3y) = 10x + 15y

Step-by-step explanation:

There is one particular way to find an equivalent expression which I am assuming is what the problem is looking for. When given a factored expression in the form of a binomial (two terms), by creating an equivilent expression, you can distribute the binomial inside the parenthesis factored by the coefficient 5. So 5(2x + 3y) = 5(2x) + 5(3y) = 10x + 15y.

5 is also the greatest common factor of 10x + 15y which is why this expression simplifies down to the equivilent expression 5(2x + 3y).

10x + 15y as a GCF is really the GCF of 10 and 15. What you do is individually split each number into all its possible factors(set of whole numbers that multiply to that number), and then find the factor that they both share.

For example, 10 has factors of 5, 2, 1, 10. And 15 has factors of 15, 1, 5, 3.

Notice how 5 appears in both.

Answer:

if the question is how much he'll have by the end of the week, the answer is $920

The equation that models the given sstatement is  $1200 + 40x

Given the following parameters

Initial amount of money in bank = $1200

If he will deposit $40 per week from his paycheck,the amount of money he willhave at the end of x weekis given as:

Total = Iniital + 40x
Total .= $1200 + 40x

Hence the equation that models the given sstatement is  $1200 + 40x

Answer:

18 will be the number of sides.

Step-by-step explanation:

As we know that the sum of exterior angles of a polygon is 360°.

The formula is:

As each exterior angle of a regular polygon is 20°.

so putting the value exterior angle 20° in the formula

The exterior angle of a polygon = 360 ÷ number of sides

                                               20  = 360 ÷ number of sides

                                               20  = 360/number of sides

so the number of sides will be:

                         number of sides = 360/20

                                                     = 18

Therefore, 18 will be the number of sides.
