Answer:
x = 4.31 and y = -1.23 (to the nearest hundredth).
Step-by-step explanation:
y = 16 - 4x
3x + 4y = 8
Substitute y = 16 - 4x in the second equation:-
3x + 4(16 - 4x) = 8
3x + 64 - 16x = 8
-13x = 8 - 64 = -56
x = -56 / -1 3 = 4.308
Plugging this value into the first equation:-
y = 16 - 4(4.308)
= -1.23
Step-by-step explanation:
Let the number be x.
Half of a number is x/2 and a third of the number is x/3

Third no is 50
Answer:
53 + 3g ≤ 65, g ≤ 4
Step-by-step explanation:
To solve for g:
53 + 3g ≤ 65
First, subtract 53 from both sides.
53 - 53 + 3g ≤ 65 - 53
=> 3g ≤ 12
Divide 3 by both sides
=> 3g / 3 ≤ 12 /3
=> g ≤ 4
Therefore, g ≤ 4
Hope this helps :)
Answer:
B
Step-by-step explanation:
Area of Trapezoid
Area = (b1 + b2)*h/2
Area = (9 + 13)*11 /2
Area = (22) * 11/2
Area = 121 sqr. units.
Area of the unshaded triangle
Area = 1/2 b * h
Area = 1/2 9 * 11
area = 49.5
Area of the shaded region
Area = 121 - 49.5
Area = 71.5
B
#1 would be 12 cm as the actual length of the thermos! This is because the scale given is 1:3 right? if you find what number 1 is multiplied by to get 3, you will obviously have 3. then, the given length of the thermos would be multiplied by 3, so it would be 3 x 4, which would be 12!
