Step-by-step explanation:i'll explain how to identify integers.
The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. For example, -5 is an integer but not a whole number or a natural number. ... Integers are numbers that do not have a fractional part, including positive and negative numbers and zero. Whole numbers are positive integers and zero. Natural numbers are positive integers and are sometimes called counting numbers. tell me if you need me to explain more.
Answer:
x = 58 and y = 15
Step-by-step explanation:
(c)
The sum of the 3 angles in a triangle = 180°
In Δ ADE
∠ DAE = 180° - (50 + 72)° = 180° - 122° = 58°
∠ DAE and ∠ CAB are vertical and congruent, thus
x = 58
(d)
Δ ACD is equilateral thus all 3 angles = 60°
∠ CAB and ∠ CAD are adjacent and supplementary, thus
∠ CAB = 180° - 60° = 120°
Since CA = BA then Δ ABC is isosceles with base angles congruent, thus
2y + 2y = 60
4y = 60 ( divide both sides by 4 )
y = 15
Answer:
2/3
Step-by-step explanation:
Multiply both sides by 4:

Answer:
The answer is D
Step-by-step explanation:
first you have to find the same denominator
the denominator will be 30 because 5×6=30 same with 6×5=30
and whatever you do to the bottom you do to the top so 4×6=24 and 7×5= 35
so its 35/30- 24/30= 11/30 so 7/6-4/5=35/30-24/30 is 11/30=11/30 which is correct.
