Answer:
300$
Step-by-step explanation:
If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300
In a class of 35 students there are five more boys than girls how many boys are in the class?
Answer:
20 boys in class
Step-by-step explanation:
easy
x+(x+5)=35
30=2x
x=15
Answer:
let X be number of boys & y be number of girls in the class
x +y = 35 .....eq 1
x = y +5
y = x -5.......... eq 2
substitute eq 2 in eq 1
x + x -5 =35
2x = 40
x = 20

The answer is 9 miles because if you divide 0.6 mile by 4 minutes, you will have an answer of 9 miles an hour, as 0.6x15=9. In a full hour, Mike would walk 9 miles.
if f(x) = 3x2 + 10, what is f( - 7)?
The value of function f(-7) is 157.
What is a function?Functions have the property that each input is related to exactly one output. The function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
For the given situation,
The function is f(x) = 3 x^2 + 10
Then f( - 7) becomes,
⇒ [tex]f(-7)=3(-7 )^{2} +10[/tex]
⇒ [tex]f(-7)=147+10[/tex]
⇒ [tex]f(-7)=157[/tex]
Hence we can conclude that the value of function f(-7) is 157.

How would you graph this correctly onto a graph?
Answer:
Here is how you graph your equations correctly :D
Step-by-step explanation:
Graph y > x − 2.
Use the slope-intercept form to find the slope and y-intercept.
Slope: 1
y-intercept: (0, -2)
Graph a dashed line, then shade the area above the boundary line since y is greater than x − 2 .
y > x - 2
Graphy < −4x + 2.
Use the slope-intercept form to find the slope and y-intercept.
Slope: -4
y-intercept: (0, 2)
Graph a dashed line, then shade the area below the boundary line since y is less than − 4 x + 2 .
y < -4x + 2
Plot each graph on the same coordinate system.
y > x - 2
Y < -4x + 2

(-4) - (+2) = -6
(+6) + (+9) = -3
(-36) divide (+3) = -12
(-12) x (-8) = 20
(-4) + (-7) = -11
(+7) - (4) = 11
(-5) - (+12) = 17
(+6) + (+9) = 15
(-10) + (+12) = -22
(+6) + (+6) = 12
(+10) divide (-10) = 1
(+4) + (-5) = -20
(-10) + (-10) = -20
(-4) x (+7) = 28
(+11) + (-2) = 9
(-2) - (-3) = 1
(-7) - (+1) = -8

You have decided to cash in all of the coins you have been saving for the summer. In total you have $7.20. You only have dimes and quarters, and you know that you have twice as many dimes as you do quarters. How many quarters do you have in total? How many dimes? (HINT: think about what you know of dimes and quarters!)
Answer:
The number of quarters in total = 16 quarters
The number dimes = 32 dimes
Step-by-step explanation:
The given information are;
The total amount of money in held = $7.20
The denomination of the money held = Dimes and quarters
The number dimes = 2 × The number of quarters
Given that a dime = 10 cents = $0.1
A dollar = 25 cents = $0.25
Let the number of quarters in the sum of money = X
Therefore, we have;
X × $0.25 + 2 × X × $0.1 = $7.20
X × $0.25 + X × $0.2 = $7.20
X × $0.45 = $7.20
X = $7.20/$0.45 = 16
Therefore, the number of quarters = 16
The number of quarters in total = 16 quarters
The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes
The number dimes = 32 dimes.
Find the slope of the line that goes through (2, -1) and (6, 1).
Answer:
Slope= y=(1/2)x-2
Step-by-step explanation:
Answer:
you would use y^1-y^2/x^1-x^2
so you would subtract 6-(-1) , it would be 7
then subtract 1-2 , it would be -1
so your answer is 7/-1

Use the following representations:
Width: W
Length: L = W + 3, or W = L - 3
Area = L*W = L*(L - 3) = 520
Equation b) is the correct one: z*(z - 3) = 520
