What do you need help with in 1A
Answer:
x = 38
y = 25
Step-by-step explanation:
To find x, you do
(2x + 5) = (3x - 33)
Subtract 2x from both sides to isolate x on one side, you get:
5 = (x - 33)
Add 33 to both sides to separate the normal number from the x, you get:
38 = x
From there, you plug x into one of the equations
2(38) + 5
The answer's 81, meaning that angle is 81 degrees. Using supplementary angles, you can find that angle ACD = 99, which you can use to find angle BCE. You'll get this equation:
(4y - 1) = 99
Add one to both sides to get rid of it, you get:
4y = 100
Divide by four, to get the y all alone:
y = 25

Step-by-step explanation:
-3.25y < -61.75

-3.25. -3.25
whenever an inequality is divided by a negative number the sign changes, so if the sign of the inequality is greater than( > ) it becomes less than( < ) or the other way around. In this case the <em>less</em><em> </em><em>than</em><em> </em>will be <em>greater</em><em> </em><em>than</em><em>.</em>
y > 19 , S.S= [ 20,21,22,23.....]
Answer:
12.1 years
Step-by-step explanation:
We are given that
Principal amount, P=$3000
Rate of interest, r=6.75% semi-annually
Amount, A=$6700
We know that
When r pays semi-annually
Where n=2
Using the formula
Taking ln on both sides we get
