Answer:
x = 18
y = 5
Step-by-step explanation:
From the figure attached,
'l' and 'm' are the parallel lines and two transversal lines are intersecting these parallel lines at points A, B and C.
Since, m∠ABC + (7x - 23)° = 180° [Supplementary angles]
m∠ABC = 180° - (7x - 23)°
m∠BCA = (11y - 1)° [Vertical angles]
m∠BAC = 49°
In ΔABC,
m∠ABC + m∠BAC + m∠CAB = 180°
180° - (7x - 23)° + 49° + (11y - 1) = 180°
-7x + 11y = -71
7x - 11y = 71 ------(1)
Since, sum of consecutive angles is 180°
Therefore, m(∠ABC) + (3x + 49)° = 180°
180° - (7x - 23)° + (3x + 49)° = 180°
-4x = -72
x = 18
From equation (1),
7(18) - 11y = 71
11y = 55
y = 5
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
Answer:
it would take it 2 hours to make 600 donuts, it makes 5 donuts a minutes
Step-by-step explanation:
Simple math.
3000/10=300 which means 300 donut per hour.
300 x 2 = 600.
300 / 60 = 5.
Answer:
8/15 left
Step-by-step explanation:
Given data
We want to perform subtraction operation on fractions
Total number of water= 5/6
we are told that 3/10 are for other runners
Hence the number of water left is
=5/6-3/10
=50-18/60
=32/60
=8/15
Hence there are 8/15 left
