Answer:
x = -6
Step-by-step explanation:
-11 - 8x = -3x + 19 (Move constants to right side)
-8x = -3x + 19 + 11 (Move x to left side)
3x - 8x = 30 (simplify)
-5x = 30 (divide both sides by -5)
x = -6
In order to solve for a variable, you need to get it by itself on one side of an equation. Depending on the equation, there are different steps to do that.
Answer:
He bought 6 chairs and 10 tables.
Step-by-step explanation:
x+y = 16
he spent = $1800
1 chair = $50
y chairs = $50y
1 table = $150
x chairs = $150x
so, 150x+50y = 1800
we got two equations :
x+ y = 16
150x+50y = 1800
Using. substitution method,
x+y = 16
so, x = 16-y
Now
150x+50y =1800
or, 150(16-y) + 50y = 1800
or, 2400-150y+50y = 1800
or, 2400-1800 = 150y-50y
or, 600=100y
so, y = 6
now,
x+y = 16
or, x + 6 = 16
so, x = 10
Answer:
132,090.30
Step-by-step explanation:
r = R/100
r = 4.6%/100
r = 0.046 per year,
A = P(1 + r/n)nt
A = 77,000.00(1 + 0.046/1)(1)(12)
A = $ 132,090.30
Answer:
60 slices
Step-by-step explanation:
Well, to start you must figure the amount of slices, to begin with. This is 9 x 8
this is = to 72.
Then you take 5/6 of 72/1 by multiplying across. to get 60
