Answer:
x = -5 ; y= -1
Step-by-step explanation:
10y = -10
y = -1
-8x = 44 -4
-8x = 40
x = -5
Answer:
x = 10
Step-by-step explanation:
X = 10 because if you look at the 28 and 14, 14 is half of 28 so the ratio is 1:2 which would also work for the 20 so the answer is 10
Given:
a.) The price of an item has dropped to $63 today.
b.) Yesterday it was $140.
For us to be able to determine the percentage decrease, we will be using the following formula:
We get,
Original Price = $140
Present Price = $63
Therefore, the decrease of the price in percentage is 55%.
Answer:
A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
Step-by-step explanation:
(a/sin(A)) = (b/sin(B)) = (c/sin(C))
we are given
(34/sin(46)) = (27/sin(B))
34sin(B) = 26sin(46)
34sin(B) = 18.702834809
sin(B) = 0.550083377
note use inverse sin function to find angle B
B = 33.372733167 approx 33.4 degrees then
C = 180 - (46 + 33.4) = 100.6
Then, (b/sin(B)) = (c/sin(C))
27/0.550083377 = c/0.982935349
0.550083377 * c = 27 * 0.982935349
0.550083377 * c = 26.539254427
c = 48.245876056 approx 48.2
.
Lastly, you get: A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
You would start by adding the 18 to the 2 to give you 20. then you would subtract x from the 6x to give you 5x. then your equation should be 5x=20, then you divide 20 by 5 and that give you 4. So x would equal 4. x=4
