Isaiah is working two summer jobs, making $16 per hour tutoring and $10 per hour clearing tables. isaiah must earn at least $110 this week. write an inequality that would represent the possible values for the number of hours tutoring, t, and the number of hours clearing tables, c, that isiah can work in a given week
Answer:
16t + 10x = 110
Step-by-step explanation:
t = tutoring
x = cleaning tables
16t + 10x = 110
All you do is plug in numbers.
Answer:
16t + 10c>=110
Step-by-step explanation:
the total earned from tutoring in a week is
16(t)
and the total earning from clearing tables per week is
10(c)
but in a week he has to earn a minimum of 110 dollars

A recipe calls for 3 cups of flour to 4 cups of sugar. Find the unit rate of flour to cups of sugar.
Answer: 0.75 cups of flour to 1 cup of sugar.
Step-by-step explanation:
From the question, we are informed that a recipe calls for 3 cups of flour to 4 cups of sugar and told to calculate the unit rate.
It simply means what we need to calculate much of flour to one cup of sugar. This will be:
= 3/4 = 0.75
Therefore, the unit rate will be:
0.75 cups of flour to 1 cup of sugar.

For A party 10 friends are byinh 100 cups 100 plates a punchbowl and 200 balloons if the friends share the cost equally how much should each friend contribute ?
100 Balloons:$7.80
100 plates:$4.75
100 cups:$5.45
100 napkins:$2.09
10 invitations: $1.60
plastic punchbowl$11.50
Answer:
$2.58
Step-by-step explanation:
First, we should divide each number by 10 to get the amount per person we get...
10 cups
10 plates
20 balloons
Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...
1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545
2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475
3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56
Now, we add them all up to get $2.58
Hope this Helps!!! :)

4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
Answer:
x = -10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
Step 2: Solve for x
Distribute: 36 - 4.5x + 36 = 102 - 7.5x - 60Combine like terms: -4.5x + 72 = -7.5x + 42Add 7.5x on both sides: 3x + 72 = 42Subtract 72 on both sides: 3x = -30Divide 3 on both sides: x = -10Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4.5(8 - -10) + 36 = 102 - 2.5(3(-10) + 24)Simplify: 4.5(8 + 10) + 36 = 102 - 2.5(3(-10) + 24)Multiply: 4.5(8 + 10) + 36 = 102 - 2.5(-30 + 24)Add: 4.5(18) + 36 = 102 - 2.5(-6)Multiply: 81 + 36 = 102 + 15Add: 117 = 117Here we see that 117 does indeed equal to 117.
∴ x = -10 is a solution of the equation.

Jason bought a new truck at $25,000. The truck depreciates 15% of its value continuously each year. How much is it worth after 5 years? Round the answer to nearest dollar.
Answer:
A = $11093
Step-by-step explanation:
Given the following data;
Principal = $25,000
Rate = 15% = 15/100 = 0.15
Time, t = 5
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.Substituting into the equation, we have;
r = -0.15 because it's depreciating.
[tex] A = 25000(1 + \frac{-0.15}{1})^{1*5}[/tex]
[tex] A = 25000(1 - 0.15)^{5}[/tex]
[tex] A = 25000(0.85)^{5}[/tex]
[tex] A = 25000*0.4437[/tex]
A = 11092.63 ≈ $11093
Therefore, the future value, A after 5 years is $11093.

-30<x/-4 answer must be simplified
Answer:
x<120
Step-by-step explanation:
-30<x/-4
In order to simplify this, we must isolate the x value by multiplying both sides by -4
Since we are dealing with inequalities and we are multiplying by a negative number, we have to switch the sign (<,>)
-30(-4)>x
x<120

Answer:
C(-2,-5).
Step-by-step explanation:
FOR A CLOCKWISE 270° ROTATION:
Given point A(x,y) its image is given
as A`(y,-x).
For the image of C which is C`(-5,2)
Comparing this to A`(y,-x)
y = -5 and -x = 2,x = -2
hence C compared to A(x,y)
will be C(-2,-5).
What is an equation of the line that passes through the points (-3, 8) and (4, 1)?
Answer:
The equation of the line is:
[tex]y=-x+5[/tex]
Step-by-step explanation:
Given the points
(-3, 8)(4, 1)Finding the slope between the points
[tex]\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{1-8}{4-\left(-3\right)}[/tex]
[tex]m=-1[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = -1 and the point (-3, 8)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-1\cdot \left(x-\left(-3\right)\right)[/tex]
[tex]y-8=-\left(x+3\right)[/tex]
Add 8 to both sides
[tex]y-8+8=-\left(x+3\right)+8[/tex]
[tex]y=-x+5[/tex]
Therefore, the equation of the line is:
[tex]y=-x+5[/tex]

What is the equation of the line through the origin and (-4,-9)?
A. y= 4x
B. y = 4/9x
c. y = 9/4x
D. y = 9x
Answer: c) y = 9/4 · x
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
m = ∆y/∆x = y₂-y₁/x₂-x₁Given points are: P(x₁ , y₁) = (0, 0) and Q(x₂ , y₂) = (-4, -9)
Substituting these two known points in the slope formula, we have:
m = (-9-0)/(-4-0) = -9/-4 = 9/4Now we can use the point-slope formula to write the equation of a line given a point on the line and the slope of the line:
m = 9/4 , given point P(x₁ , y₁) = (0, 0)
Formula = (y-y₁) = m(x-x₁) (y-0) = 9/4(x-0) y = 9/4 · xAnswer: c) y = 9/4 · x
