Joe is 3 years less than twice as old as Sara. The sum of the ages of Joe and Sara is 42. If x represents Sara's age,
Answer:
Sara or x=15, Joe=27
Step-by-step explanation:
Using J to represent Joe and S to represent Sara
J=2S-3
J+S=42 or J=42-S
Substitute for J:
42-S=2S-3
3S=45
S=15
J=2(15)-3 = 27

Han has Spent 75 minutes practicing the piano over the weekend priya practice the violin for 152% as much time as hand practicing piano how long does she practice
Answer: 114 minutes
Step-by-step explanation:
From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.
Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:
= 152% × 75 minutes.
= 152/100 × 75minutes
= 1.52 × 75 minutes
= 114 minutes

times by 7
The number of boys attended are 49.
What is the definition of the ratio?In mathematics, a ratio is a term used to compare two numbers. It is used to express how large or small an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the 'antecedent,' while the divisor is referred to as the 'consequent.'For the given question.
Let the number of girls be 'x' = 63.
Let the number of boys be 'y'.
The ratio of girls to boy is 9:7.
Thus,
x/y = 9/7
Boys = ?
y = 7x/9
Put x = 63
y = 7×63/9
y = 49
Thus, the number of boys attended are 49.

What is the slope line through 1,-1 and 6,2
Answer:
[tex]\huge\boxed{slope=\dfrac{3}{5}=0.6}[/tex]
Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (1, -1) and (6, 2).
Substitute:
[tex]m=\dfrac{2-(-1)}{6-1}=\dfrac{2+1}{5}=\dfrac{3}{5}=0.6[/tex]

Lin notices that the number of cups of red paint is always 15 of the total number of cups (0.2 of the total number of cups). She writes the equation r = 15t (r = 0.2t) to describe the relationship. Which is the independent variable? Which is the dependent variable? Explain how you know.
Step-by-step explanation:
The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.
She writes the equation r = 15t (r = 0.2t) to describe the relationship.
In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.
The number of cups of red paint is a dependent variable as it depends on the number of cups.

Nina Milling assembles transistor radios. she is paid $0.54 for each radio assembled during a regular work week, $0.62 for each radio assembled on on sundays. What is Nina's total pay for a week in which she assembled the following number of radios?
Answer:
I would need to know the number of radios she made each day.
Step-by-step explanation:
lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***
you would get $6.48
then for sunday we would do 0.62 x 2 (that would be 1.24) .
now we add 6.48 and 1.24 to get $7.72 a week.
Solve for v.
19v – 18 = 16 + 17v
Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
Answer:
v = 17
Step-by-step explanation:
Given
19v - 18 = 16 + 17v ( subtract 17v from both sides )
2v - 18 = 16 ( add 18 to both sides )
2v = 34 ( divide both sides by 2 )
v = 17

A line passes through the points (-8, 7) and (-11,-11). Find the value of a such 1 point
that the point (-7,a) lies on the line. a=
Your answer
Answer:
a=12
Step-by-step explanation:
we need the slope of this line. Find it with the slope formula
m= y2-y1 / x2-x1 with the points given p1=(-8,7) and p2=(-11,-11)
m=-11-7 / -11-(-8) (x1,y1) (x2,y2)
m= -18 /-11+8
m= -18 / - 3
m= 6
next plug in one of the point into the point-slope formula [y-y1=m(x-x1)]
y-7=6(x-(-8)) ( simplify this towards the slope intercept form [y=mx+b]
y-6=6(x+8)
y-6=6x+48
y=6x+54
now we can plug in our point of (-7,a) to find what a is
a=6(-7)+54
a=-42+54
a=12

Step-by-step explanation:
Answer:
I will help with 10 i don't get 9 sorry so the answer is (a) F(5,4)
Step-by-step explanation:
So you have the midpoint and you put f(x, y) and D(-3,-8)
So
E=(x-3/2, y-8/2) =(1,-2) so
X-3/2 =1 , x-3=2 so x = 5
And y-8/2 = - 2. , so y-8 = - 4. , so y =4
So F =(5, 4)

16. Find the length of the median CD.
17. Find the coordinates of E, the midpoint of BC
18. Find the length of the median AE.
Step-by-step explanation:
16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)
C (2,-3) D (6,3)
CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)
CD = sqaureroot of ( 16 + 36)
CD = sqaureroot of 52 = 2 root 13 = length
17. E (5, - 1) because the point is under the x axis.
Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)
B (8,1) C (2, - 3)
Midpoint of BC = ((2+8)/2 , (-3+1)/2)
= (10/2 , - 2/2)
= (5, - 1)
18. Length of AE
A (4,5) E(5,-1)
Square root of ((5-4)^2 + (-1-5)^2)
Square root of (1^2 + - 6^2)
Square root of ( 1 + 36)
Square root of 37 = root 37
