Answer:
the missing angles are 47,° 77,° 56°
Step-by-step explanation:
(133)+(x+13)= 180° (angles on a straight line)
133+x+13= 180°
146+x= 180°
X= 180-146
X= 34°
FOR ANGLE A
2X+9= 2(34)+9= 68+9= 77°
FOR ANGLE C
X+13= 34+13= 47°
FOR ANGLE B
47+77+Y= 180 (SUM OF ANGLES IN A TRIANGLE)
124+Y= 180
Y= 180-124= 56°
Y= 56°
the missing angles are 47,° 77,° 56°
To subtract fractions, we need an lcd( lowest common denominator)
8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction
to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)
to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)
these two numbers now have the same denominator so we subtract them
24/42 - 21/42 = 3/42 which simplifies to 1/14
9. since these fractions already have a common denominator, we will make them mixed fractions
-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7
-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7
now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7

Answer:
Here's The Answer: 4
Step-by-step explanation:
-4x²+2x+4 = 4
I'm Sorry If I Get This Wrong.
We know that the cost of an apple and a banana equals $1.60
a + b = 1.60
We also know that the cost of a banana is 3 times that of an apple
3a = b
If we divide 4 from 1.60 we will get the price of 1 apple
4a = 1.60
1 apple costs $0.40
So that means 1 banana costs $1.20
