I think the answer 5 over 2
Answer:
c = (d/a) - b
Step-by-step explanation:
a(c + b) = d
Divide both sides by a
c + b = d/a
subtract b from both sides
c = (d/a) - b
Answer:
201.5x-y=-6
Step-by-step explanation:
−6x−2y=−1618x+6y=48
Collect like terms
-6x+1618x-2y-6y=-48
1612x-8y=-48
Divide through by 8
1612x/8-8y/8=-48/8
201.5x-y=-6
Answer:
Solution given:
y+135°=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
y=180°-135°
y=25°
again
2x-1+3x+1=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
5x=180
x=180/5.x=36
<u>x</u><u>=</u><u>3</u><u>6</u><u>°</u><u>,</u><u>y</u><u>=</u><u>2</u><u>5</u><u>°</u>
Answer:
Expenditure x (in hundreds of dollars) = $2,000
Step-by-step explanation:
Given:
Profit p (in hundreds of dollars)
Expenditure x (in hundreds of dollars)
p(x) = -0.5x² + 20x + 23
Find:
Expenditure for advertising .
Computation:
x = -(Cofficient of x) / 2(Cofficient of x²)
x = -(20) / 2(-0.5)
x = 20
Expenditure x (in hundreds of dollars) = 20 × $100
Expenditure x (in hundreds of dollars) = $2,000
