use the graph to estimate the solution to the system of equations shown.
A. x=5 1/2, y= 3 1/4
B. x= -3 1/2, y= -5 1/4
C. ×= 3 1/2, y= 5 1/4
D. x= -5 1/2, y= -3 1/4
Answers
==============================================================
Explanation:
The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate
Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.

What percent of 120 is 42?
can you show your work, please
Answers
42:120*100 =
(42*100):120 =
4200:120 = 35
Now we have: 42 is what percent of 120 = 35
Question: 42 is what percent of 120?
Percentage solution with steps:
Step 1: We make the assumption that 120 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=120$100%=120.
Step 4: In the same vein, $x\%=42$x%=42.
Step 5: This gives us a pair of simple equations:
$100\%=120(1)$100%=120(1).
$x\%=42(2)$x%=42(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{120}{42}$
100%
x%=
120
42
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{42}{120}$
x%
100%=
42
120
$\Rightarrow x=35\%$⇒x=35%
Therefore, $42$42 is $35\%$35% of $120$120.
42/120 = 0.35
0.35 x 100 = 35%

The triangular prism above has been created with two equilateral triangles and three congruent rectangles the height of the triangle is 3.5 inches find the surface area of the triangular prism
Answers
Answer:
108 inches square.
Step-by-step explanation:
Here
base= b= 4 inches
height = h=w= 3.5 inches
and length = l= 9 inches
The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by
Area of the 2 Δs= b* h= 4*3.5= 13.5 inches square
Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5 inches square.
Total area = 13.5 + 94.5 = 108 inches square
This can be found by applying another formula.
Surface area of the triangular prism = bh + ( s1+s2+s3) H
= 4*3.5 + (9+9+9)3.5
= 13.5 + 94.5= 108 inches square.
where H is the width of the recatngles which is equal to the height of the triangles.

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answers
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)

A video rental store charges a $20 membership fee and $2.50 for each video rented.
Write a linear equation to model this situation.
Tell what each variable represents.
Answers
Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y

No, the triangles are not similar.
Step-by-step explanation:
For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180
180-70=110, 110-58=52 ∠N = 52°
since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.
