Let the yellow corn be x
And other variety be y
Question says that she brought a dozen (as total)
So,
x +y = 12
If cost of yellow corn was 40 cent and cost of other varieties were 50 cents then,
(After changing those cents into dollar)
0.40x+ 0.50y = 5.70
Because she paid a total of 5 dollar 70 cents for yellow and other variety.
So, option "a" is correct.
Answer:
120
Step-by-step explanation:
well it have to be a nuber by 5, 10 etc
also even too
so that be 120
Answer:
Y= 2x+2
Step-by-step explanation:
line equation is y=mx +c
m is the gradient = 2
We are given an x and y value
X= 1
y= 4
substitute that into the equation:
4= 2(1) +c
2=c
Put all the equation together:
Y= 2x+2
Answer:
-14
Step-by-step explanation:
(-4)(5)+(-3)(-2)
=-20+6
=-14
Answer:
70°
found by considering A-frame ladder as a triangle
Step-by-step explanation:
Given that,
angle form on either side of A-frame ladder with the ground = 125°(exterior)
As it is a A-frame ladder so its a triangle, we will find the angle at the top of ladder by using different properties of triangle
1) find interior angle form by A-frame ladder with the ground
125 + x = 180 sum of angles on a straight line
x = 180 - 125
x = 55°
2) find the angle on top of ladder
55 + 55 + y = 180 sum of angle of a triangle
110 + y = 180
y = 180 - 110
y = 70°
