Answer:
Issac worked 24.4 hrs, Ruby worked 31.4 hrs, and George worked 94.2 hours
Step-by-step explanation:
x= hours worked
Issac= x Ruby= (x+7) George= 3(x+7)
x+(x+7)+3(x+7) = 150 [distribute 3 to (x+7)]
x+(x+7)+(3x+21) = 150 [add from left to right]
5x+28 = 150 [subtract 28 from both sides]
5x = 122 [divide both sides by 5]
x=24.4
Now plug the x value back into Issac, Ruby, and George's equations:
Issac=x=24.4
Ruby=x+7=31.4
George=3(x+7)=94.2
Double check by adding all their work hours together
24.4+31.4+94.2=150!!

1 d.p:
4.03834 = 4.0
24.8845 = 24.9
0.62346 = 0.6
2.3999 = 2.4
The 1 d.p is the first number after the decimal point and to write it as 1 d.p you need to round it off.
2 d.p:
4. 03834 = 4.04
24.8845 = 24.88
0.62346 = 0.62
2.3999 = 2.40
The 2 d.p is the second number after the decimal point.
3 d.p:
4.03834 = 4.038
24.8845 = 24.885
0.62346 = 0.623
2.3999 = 2.400
The 3 d.p is the third number after the decimal point.

[tex]\frac{3}{16}[/tex]
Step-by-step explanation:
We do the division first because of PEMDAS.
Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
Therefore,
[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]
Multiply the two fractions:
[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]
[tex]\frac{5}{8}-\frac{7}{16}[/tex]
The LCM of the denominators (8 and 16) is 16.
Adjust fractions:
[tex]\frac{10}{16}-\frac{7}{16}[/tex]
Subtract:
[tex]\frac{10-7}{16}[/tex]

Answer:
y-intercept and slope
Step-by-step explanation:

What is Mathematical equation ?
By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.
So, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.
Let, consider the equation of y = mx+c, where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.
Therefore, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.

To find:
Which of the following options is an equation.
Solution:
A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.
In option A,
[tex]5-4=9[/tex]
[tex]1\neq 9[/tex]
LHS≠RHS. So, it is not an equation.
In option B and C,
[tex]5+4=9[/tex]
[tex]9=9[/tex]
LHS=RHS. Both are equations.
In option D,
[tex]5+4-9[/tex]
This is an expression, not an equations.
Therefore, the correct options are B and C.
Suppose that you plan on taking a summer job selling magazine subscriptions. The magazine company will pay you $ 1.25 for selling the first subscription. For each additional subscription sold, the magazine company will pay you 15 cents more than what was paid for the previous subscription. How much will you earn by selling 175 magazine subscriptions?
Answer: $27.35
Step-by-step explanation:
First let's find the variables.We will use x to represent the number of subscription sold and y we will represent the amount of money you will get paid.
So we know that , if you sell One You will get $1.25 so we could represent it by the point (1,1.25) .
Now the second statement says that if you sell an additional subscription you will get an additional 15 cents or $0.15.Which means if you sell the second subscription, you will get $1.40 because it is an additional 15 cents. We can also represent that by the point (2,1.40)
Now using the two points come up with an equation.
(1,1.25)
(2,1.40) Find the slope and y intercept.
TO find the slope find the difference between y and divide it by the difference in x.
1.25 - 1.40 = 0.15
1 - 2 = 1
0.15/ 1 = 0.15 So the slope is 0.15
Now use the point to find the y intercept. using the y-intercept formula,
y = mx + b
1.25 = 0.15(1) + b
1.25 = 0.15 + b
-0.15 0.15
b = 1.1
We can now write the equation y = 0.15x + 1.1 to represent the whole situation where x is still the number of subscriptions sold and y is the money you will get paid. Now to find how much you will earn for 175 subscriptions, you will input 175 for x and solve for y.
y = 0.15(175) + 1.1
y = 26.25 + 1.1
y = 27.35
So you will earn $27.35 for 175 subscriptions
