Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.

Answer:
Step-by-step explanation:
This is a geometric sequence of the form [tex]F=Ir^t\text{ where I=initial value, r=common ratio, and t=number of terms or time. Notice each term is 1/4 of the preceding term. This is the common ratio. So your equation is }f(x)=40\left(\frac{1}{4}\right)^x[/tex]

Use the information to answer the following question.
A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
What does the algebraic expression (w + 4)(w + 7) represent in this context?
A. the perimeter of the walkway only
B. the area of the garden only
C. the perimeter of the garden only
D. the total area of the garden and walkway
Answer:
D. the total area of the garden and walkwayStep-by-step explanation:
Sides of the rectangular garden:
w and w + 3Add the width of the walkway, 2 feet from both sides, the total of 4 feet:
w + 4 and w + 7The product of the above is the area of the garden and the walkway
Correct option is D

rearrange the following linear equation into y=mx+b form and identify the slope and the y intercept 2y=2x+6
Answer:
Step-by-step explanation:
we need the equation to be like y=mx+b so we have to simplify our equation
2y=2x+6
divide everything by 2
so it’s y=x+3 and that’s ur answer

6x + 3y = -12
-6x - 2y = 4
Answer:
x=2
y=-8
Step-by-step explanation:
6x+3y=-12
-6x-2y=4
3y=-12-6x
y=(-12-6x)/3
y=-4-2x
substitute y
-6x-2(-4-2x)=4
-6x+8+4x=4
-2x=-4
x=2
6(2)+3y=-12
12+3y=-12
3y=-24
y=-8
check:
6(2)+3(-8)=-12
12-24=-12
-6(2)-2(-8)=4
-12=16=4
What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.
Answer:
That is a 30 60 90 triangle.
In such a triangle the "middle" size = short side * sq root (3)
height = 5 * sq root (3) = 8.6602540378
Area = (1/2) * 5 * 8.6602540378
Area = 2.5 * 8.6602540378
Area = 21.6506350946 square centimeters

Answer:
A=24√3
Put In Decimal Form:41.5692193817^3
Step-by-step explanation:
4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.
A=1/2(4)(4√3)
2(12√3)
24√3

3a+14-9
subtract 9 from 14
3a+5
Answer:
[tex] \sf \: 3a + 5[/tex]
Step-by-step explanation:
Given expression,
→ -4a + 14 + 7a - 9
Let's simplify the expression,
→ -4a + 14 + 7a - 9
→ (-4a + 7a) + (14 - 9)
→ (3a) + (5)
→ 3a + 5
Hence, the answer is 3a + 5.
Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.

Answer:
15.08 m
Step-by-step explanation:
You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.
Angle XZW is 180° -108° = 72°
The circumference is C=πd, so the arc of interest is ...
XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m
XW ≈ 15.08 m
_____
If you use π = 3.14, then your answer will be 15.07 m.

Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.

Answer:
41
Step-by-step explanation:
Use PEMDAS.
3^2 = 9
9 - 6 = 3
3 × 5 = 15
8 × 7 = 56
56 - 15 = 41
