10x+2x+13=145
angle of WIJ and HIW is equal to 145 degrees
12x+13=145
12x=132
x=11
angle of WIJ is 10x
angle of HIW is 2x+13
to find angle of HIW, you plug in x=11 into 2x+13 and
the answer and angle of HIW is 35 degrees.
Answer:
The area of the shaded region is 21.45cm².
Since both are equivalent to y, the equations must be equivalent.
x^2-x-3= -3x+5
x^2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
Plug the values of x in to either equation
y=-3(-4)+5
y= 12+5
y=17
y= -3(2)+5
y=-6+5
y=-1
Final answer: (-4,17) and (2,-1)
Answer:
4 batches
Step-by-step explanation:
Total syrup made by Tamita = 18.5 ounces
Amount of ounces per batch = 4 ounces
If 1 batch = 4 ounces
x batches = 18.5 ounces
Cross multiply
4 * x = 18.5
x = 18.5/4
x = 4.625
Hence she can only make 4 batches of syrup
Let the number be x, then
1/5 * x = 2/3 * 90
1/5 x = 60
x = 60 * 5 = 300 (answer)
