Step-by-step explanation:
to convert a mixed number to an improper fraction: take the big whole new on the right and multiply it by the denominators or number on the bottom of the fraction. then add thay amount to the numerator, or number on top and leave the denominator as it was before
example: 2 3/5 = 13/5
you can dissect the example to figure out the formula (formula is the way to solve an equation)
Answer:
31.5/15 = 2.1
2.1 x 18 =37.8
Check by Soh Cah Toa
1) Tan-(15/18)=40* to 1d.p for angle ACB
Tan-(18/15)=50* to 1d.p for angle ABC
40 + 50=90
90+90 (in the right angled triangle) =180*
Angle in triangle add to 180
Let's check for the big triangle:
Opposite angles are equal. So, DCE is 40.
DE is opposite, x is adjacent.
Tan(40) = o/a
=31.5/x
Multiply by x both side
Tan(40) multiply by x = 31.5
Divide by Tan(40) both side and get x on its own.
x=31.5/Tan(40)
= 37.54023817.
So, x = 37.5 to 1 d.p
Pythag to fin hypotenuse of both triangle and divided by each other to see if it matches decimal multiplier at the start of my solution.
49/23=2.1 (all values to 1d.p)
Also, 37.5/18 = 2.1 to 1 d.p
Answer:
A. (3, -1)
Step-by-step explanation:
The ordered pair that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are plugged into 4x - 3y < 16
Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair in the options that makes the inequality true. Thus:
Substitute x = 3 and y = -1 into 4x - 3y < 16
4(3) - 3(-1) < 16
12 + 3 < 16
15 < 16 (TRUE)
