Answer:
x = -18
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply 2 to both sides:
(x/2) * 2 = (-9) * 2
x = -9 * 2
x = -18
x = -18 is your answer.

Eight x plus y equals two over seven
Answer:
Step-by-step explanation:
Let X be number of woodland bicyles and Y grande expedition
Our objective is to maximize profit
Z = 250x+350Y
Constraints are: 2x+3y<450 and
x+y<375
(given)
Solution gives negative y. Hence intersecting point is not within constraint.
So choices satisfying the constraints would be min of 225, 375 for x and min of 150,375 for x
i.e x=225 and y =150
To maximize revenue 225 Woodland and 150 Grande to be produced
0, I put y=(0-7)x into a graphing calculator
To earn $345.45 simple interest in 7 years, you have to invest $940.
<u>Step-by-step explanation:</u>
Step 1:
Given details are Simple Interest Rate (R) = 5.25%, Simple Interest (SI) = $345.45, Time (T) = 7 years
Step 2:
Use the above details to find principal using the formula for Simple Interest (SI) = PRT/100
⇒ 345.45 = (P × 5.25 × 7)/100
⇒ 34545 = 36.75 P
⇒ P = $940
