Solve for a: -8b+2a=6c
Answer:
a=3c+4b
Step-by-step explanation:
-8b + 2a = 6c
(-8b + 2a) + 8b = 6c + 8b
-8b + 2a + 8b = 6c + 8b
-8b + 8b + 2a = 6c + 8b
2a = 6c + 8b
2a/2 = 6c + 8b/2
a = (2x3)c + [tex]2^{3}[/tex] x b)/2
a = 3c + 4b

How many sides does the polygon have?
I
11
11. What is the measure of each interior angle of a
regular pentagon?
12. The exterior angles of any polygon add to
12
Answer:
Step-by-step explanation:
10. To solve for this, use the formula: 180*(n-2)
So, 180(n-2) = 2,340
Once n is solved for, that is the number of sides
11. Use the formula:
[180*(n-2)]/n
(n represents the number of sides)
12. Think of the sum of all interior angles in a quadrilateral

A grocery store is offering a sale on bread and soup. Kacey buys four cans of soup and three loaves of bread for $12.35. Fernando buys eight cans of soup and one loaf of bread for $13.05. a. Write equations for both Kacey's and Fernando's purchases.
Answer:
[tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]
Step-by-step explanation:
Given data
let bread be x
and soup be y
Kacey buys four cans of soup and three loaves of bread for $12.35
4x+3y=12.35-------------1
Fernando buys eight cans of soup and one loaf of bread for $13.05
x+8y= 13..05-------------2
Hence the equation for both of their purchase is [tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]

Answer:
p : q = 3 : 2
Step-by-step explanation:
You are given sufficient information to write two relations involving p and q. We presume these will be sufficient to find an answer to the question. We will be able to find p and q. Then we can find their ratio, as the problem asks.
(p-15)/(q-15) = 2/1
(p+30)/(q+30) = 5/4
__
From the first equation, we get ...
p -15 = 2(q -15)
p = 2q -15 . . . . . . . add 15, simplify
From the second equation, we get ...
4(p +30) = 5(q +30)
4p + 120 = 5q + 150
4p = 5q + 30
Using the first equation to substitute for p, we have ...
4(2q -15) = 5q +30
8q -60 = 5q +30 . . . eliminate parentheses
3q = 90 . . . . . . . . . . . add 60-5q to both sides
q = 30 . . . . . . . . . . . . divide by 3
p = 2q -15 = 2(30) -15 = 45
Then the desired ratio is ...
p : q = 45 : 30
p : q = 3 : 2

Answer:
Step-by-step explanation:
center (-1, -2) , trough point ( 6, 4)
equation of the circle
r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2
r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4
r² =(6+1)²+(4+2)²
r²= 7² +6²
r²= 85
so the equation is
(x+1)²+(y+2)²= 85
to find the points on the circle substitute in the equation x and y
(-10+1)²+(0+2)²= 85 ; 85=85 true
so the pint on the circle is (-10, 0)

Answer:
$33.81
Step-by-step explanation:
Strawberries = $2.49 Per Pound (Bought 3)
Blueberries = $3.19 Per Pound (Bought 2)
Pineapples = $4.99 Per Pound (Bought 4)
So we have to multiply each price with the number of fruits bought.
So, For Example, Strawberries: $2.49 × 3 = $7.47
After you did all three individually, add them all up.
Strawberries : $7.47
Blueberries : $6.38
Pineapple : $19.96
Total = $33.81

Answer:
Choice #1) 4.7 cm
Step-by-step explanation:
circumference of full circle = 2(r)(3.14)
a full circle would be = 2(3)(3.14) = 18.84 cm
It is 1/4 circle so 18.84/4=4.7 cm
Answer:
10.7
Step-by-step explanation:
1. I first grabbed a ruler to measure the other straight side of the figure.
2. Both of the straight sides were 3 cm so I knew that the answer had to be greater than 6 cm.
3. I then estimated that the other side was longer than the 3 cm.
4. I then had to my logic to figure out the answer and I very quickly realized that 4.7 cm would not make since because that is less than 6 cm. I know 7.7 cm would not make since because I knew the curved side was longer than 3 cm not shorter. 18.8 cm did not make since because that answer has WAY to much cm. Using the process of elimination, 10.7 cm was the only answer that made since.
