Answer:
Please check the explanation.
Step-by-step explanation:
Part 1)
5x + 9y, when x=8, y=11
substituting x=8, y=11 in 5x + 9
5x + 9y = 5(8) + 9(11)
= 40 + 99
= 139
Part 2)
a³ –c + b, when a=3, b=6, c=8
substituting a=3, b=6, c=8 in a³ –c + b
a³ –c + b = (3)³ - 8 + 6
= 27 - 2
= 25
Part 3)
4(g –h) +10, when g=12, h=7
substituting g=12, h=7 in 4(g –h) +10
4(g –h) +10 = 4(12 - 7) + 10
= 4(5) + 10
= 20 + 10
= 30
Part 4)
k³ –4j +12, when k=8, j=2
substituting k=8, j=2 in k³ –4j +12
k³ –4j +12 = (8)³ - 4(2) + 12
= 512 - 8 + 12
= 516
Summary:
113,115,117 if you add them up you should get 345
3x + 4y = 5
<u>-5x - 4y = -11</u>
-2x = -6
-<u>2x</u> = <u>-6</u>
-2 -2
x = 3
3(3) + 4y = 5
9 + 4y = 5
<u> -9 -9</u>
4y = -4
<u>4y</u> = <u>-4</u>
4 4
y = -1
(x, y) = (3, -1)
It will be the same because my teacher told me you cant add something thats squared to something that isnt
Answer:
diameter = 3,600 units
Step-by-step explanation:
Let 
= 3.14
C = 2r
11,304 = 2(3.14)r
r = 1,800
d = 2r = 2(1,800) = 3,600
