Answer:
c = 49
Step-by-step explanation:
Let c = number of cards originally
give away 8 cards
c-8
Now she has 41
c-8 = 41
Add 8 to each side
c-8+8 = 41+8
c = 49
Answer:
49
Step-by-step explanation:
In the end, if she now has 41 cards you have to do inverse operation. Since you subtracted to take away those 8 cards she gave away, you have to add back in 8 cards to the 41 if you want to find what she had before. So, 8 + 41 = 49
Hope this helps! :)

Question 4
What is the equation of the line that is parallel to y−5=−13(x+2) and passes through the point (6,−1)?
Answer:
y= -13x+77
Step-by-step explanation:
Parallel lines do not share any points but have the same slope.
First, put the equation y-5=-13(x+2) into slope-intercept form.
y= -13x-21
Slope= -13x
Y-Intercept= (0,-21)
Now that we know the slope...
y-(-1)=-13(x-6)
becomes
y+1=-13x+78
y-1=-13x+78-1
y=-13x+77

Answer ) -12xy
Step-by-step explanation:
6x × (-2y) = -12xy thank youThe cost price of a box and a pen isRs 120 The box is sold at lo% profit and the pen is sold at 10% loss. If the selling price of the box is Rs 52 more than that of the pen, calculate the profit or loss percent in a whole.
Answer:
profit of 3.33%
Step-by-step explanation:
Answer:
3.33%Step-by-step explanation:
Cos of Pen = pCos of Box = bb + p = 1201.1b - 0.9p = 52Solve the system by substitution:
p = 120 - b1.1b - 0.9(120 - b) = 521.1b + 0.9b = 52 + 1082b = 160b = 160/2b = 80Find p:
p = 120 - 80 = 40Total profit or loss:
80*1.1 + 40*0.9 - 120 = 4 (profit as positive)Profit percent:

there are x boys and y girls at the camp.how many children are at the camp altogether?
(EXPRESS YOUR ANSWER IN TERMS OF X AND Y )
Answer;
no.of boys = x
no.of girls = y
total no.of children in camp = no.of boys + no.of girls
= x + y..........
Answer:
total children = x+y
Explanation:
The total numper of children at the camp would be the sum of the total number of boys and the total number of girls.

1 by 6 of a construction work is finished in the first year, 1 by 8 part in the second year and 1 by 12 in the third year how much work is finished in 3 year
Answer:
3/8
Step-by-step explanation:
first year's work is 1/6
second year's work is 1/8
third year's work is 1/12
combining all 3 gives us
1/6 + 1/8 + 1/12
which simplifies to 3/8

Find the volume of the of the shaded area for the solid below.
Answer:
Below
Step-by-step explanation:
First we can find the volume of the box
v = lwh
v = (20)(16)(16)
v = 5120 in^3
Find the volume of the cylinder using this formula
V = πr^2h
V = π(5)^2(20)
V = 1570.79633 (plug this into the final equation, not the rounded one in case it screws up the final value)
V = 1570.8 in^3
Now we can find the volume of the shaded region by subtraction
5120 - 1570.7963= 3549.2037
Rounding to the nearest 10th and you get....
V = 3549.2
Hope this helps!

Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= 4x + 2 The function g of x going through 0, negative 2 and 1, 3 (1 point) The function f(x) has a larger slope. The function g(x) has a larger slope. They both have the same slope. The relationship between slopes cannot be determined.
Answer:
g(x) has the larger slope.
Step-by-step explanation:
f(x) = 4x + 2
- so its slope = 4. ( from general form y = mx + c where m = slope).
The slope of g(x) = (3 - (-2) / (1 - 0)
= 5.

WHERE ARE THE EXPERTS AND ACE!!!!!!! I NEED HELP PLS SHARE YO SMARTNESS!!!!! WILL GIVE BRAINLIEST AND RATE AND VOTE!!! EASY IM JUST NOT SMART
This value is approximate.
=========================================================
Work Shown:
First we need to find angle C
A+B+C = 180
46+73+C = 180
119+C = 180
C = 180 - 119
C = 61
This is not the final answer, so answer choice B is likely a trick/trap answer.
We'll use this angle value to help find side c. Use the law of sines
c/sin(C) = b/sin(B)
c/sin(61) = (32.3)/sin(73)
c = sin(61)*(32.3)/sin(73)
c = 29.5410185554849 which is approximate
c = 29.5 which points us to choice A as the final answer.

Need help asap algebra 2 math
f(x) = 5x^2 + 25x + 30
============================================================
Explanation:
The roots, aka x intercepts, of this curve are x = -3 and x = -2. This is where the graph crosses the x axis.
Since x = -3 is a root, this makes x+3 a factor of the quadratic. Similarly, x = -2 leads to x+2 as another factor. I'm using the zero product property.
So far we have found that the polynomial is (x+3)(x+2). This isn't the full factorization because if we plugged x = -1 into that expression, then we would get
y = (x+3)(x+2)
y = (-1+3)(-1+2)
y = (2)(1)
y = 2
But we want y = 10 instead. So we must multiply that factorization by 5 to jump from 2 to 10 (i.e. 5*2 = 10)
Therefore, the full factorization of this parabola is y = 5(x+3)(x+2)
Now let's expand everything out and simplify
y = 5(x+3)(x+2)
y = 5(x^2+2x+3x+6)
y = 5(x^2+5x+6)
y = 5x^2+5*5x+5*6
y = 5x^2 + 25x + 30
Choice C is the final answer
-------------------------
To check this, we can plug in x = -3 and we should get 0
y = 5x^2 + 25x + 30
y = 5(-3)^2 + 25(-3) + 30
y = 5(9) + 25(-3) + 30
y = 45 - 75 + 30
y = -30 + 30
y = 0
This proves that x = -3 is a root of y = 5x^2 + 25x + 30
I'll let you check x = -2. You should also get y = 0 when plugging this x value in.
Plugging x = -1 should lead to y = 10 as the last bit of confirmation. I'll let you check this one as well.

Determine the value of y, if x is -5.
y = |x| – 6
Answer:
The value of y = -1 , if x is -5.
Step-by-step explanation:
y = |x| – 6
y = |-5| – 6
|-x| = x ---> this is the rule of absolute value, so let's apply this to our equation.
y = 5 – 6 --------------> -5 becomes 5
y = -1

Area: 2 x 10=20
perimeter: 2(2+10)=24
Step-by-step explanation:
Hopefully this helps
Answer:
P = 24
A = 20
Step-by-step explanation:
The perimeter is calculated by multiplying the sum of width + length by 2
P = 2*(10+2)
P = 24 yd
the area is calculated by multiplying width and length
A = 10*2
A = 20
