you save $15 per week to purchase a bike that costs $120. write and solve an inequality to find the number of weeks you need to save to purchase the bike.
Answer:
Must save 8 weeks or more to purchase the bike.
Step-by-step explanation:15*w >= 120 where W is the number of weeks.
w >= 120/15 = 8
You need to save $15 every week for the next 8 weeks in order to purchase the bike.
What is inequality in mathematics?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given is that you save $15 per week to purchase a bike that costs $120.
Assume that you need [w] weeks to save $120 for the bike.
Amount earned per week [A] = $15
Amount earned in [w] weeks [W] = $15w
Money needed [R] = $120
The inequality can be written as -
[W] ≥ [R]
We can write it as -
15w ≥ 120
Solving the inequality, we get -
15w/15 ≥ 120/15
w ≥ 8
Therefore, you need to save $15 every week for the next 8 weeks in order to purchase the bike.

Find the value of 1.999.... in the form of p
q
where p and q are integers.
1.999… is exactly the number 2.
Let x = 1.999… . Then 1000x = 1999.999… . Subtract x from this to eliminate the fractional part, and you get
1000x - x = 1999.999… - 1.999…
1000x - x = 1999 - 1
999x = 1998
x = 1998/999 = 2/1 = 2
So p = 2 and q = 1.

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?
Answer:
625
Step-by-step explanation:
Let two number be x and (50-x).
The product of numbers be x(50-x).
P = 50x-x²
For maximizing the product,
[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]
So, the maximum product, P = 50(25)-(25)²
P = 625
Hence, the maximum value of the product of these two numbers is 625.

Which measurement is the same length as 1 meter
Answer:
3 feet
Step-by-step explanation:
From the option available the measurement 1 meter is equal to 100 centimeters.
What is unit conversion?The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.
given the measurement is 1 meter
1 meter is equal to 100 centimeters
From unit conversion:
1 meter is also equal to 3.2808 feet
1 meter is also equal to 39.3701 inch
1 meter is also equal to 1000 millimeters
1 meter is also equal to 1.093 yards.

HELP ASAP!!! Make t the subject of 5(t − g) = 2t + 7
Answer:
t=(7+5g)/3
Step-by-step explanation:
5(t-g)=2t+7
5t-5g=2t+7
5t-2t=7+5g
3t=7+5g
divide both side by 3
t=(7+5g)/3
As per linear equation, the variable 't' is subject of 5(t -g) = 2t + 7 as [tex]t = \frac{5g + 7}{3}[/tex].
What is a linear equation?"A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.
There are linear equations in one variable and linear equations in more than one variable. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
The given linear equation is:
5(t - g) = 2t + 7
We can calculate the value of the variable 't' by keeping it in the left hand side of the equation and then rest of the elements on the right hand side of the equation. Now we get:
⇒ 5t - 5g = 2t + 7
⇒ 5t - 2t = 5g + 7
⇒ 3t = 5g + 7
⇒ [tex]t = \frac{5g + 7}{3}[/tex]
Therefore, the value of the variable 't' in terms of the variable 'g' is [tex]t = \frac{5g + 7}{3}[/tex].
