30 - 29 = 1 for the first one.
It is 39
Because you have to count the little dots all the way till it is around the most age.
Answer:
cement by 5 Kg
Step-by-step explanation:
add the parts of the ratio, 5 + 4 + 1 = 10 parts
Divide the quantity of concrete by 10 to find the value of one part of the ratio.
110Kg ÷ 10 = 11Kg ← value of 1 part of ratio , thus
5 parts = 5 × 11Kg = 55Kg ← cement required
4 parts = 4 × 11Kg = 44Kg ← sand required
1 part = 11Kg ← gravel required
He requires 55Kg of concrete but only has 50Kg.
He requires 44Kg of sand and has 55Kg
He requires 11Kg of gravel and has 15Kg
Thus he is 5Kg short of cement.
If looking for the answer it would be 0, 3, -6, 7
Parallel line means having the SAME slope
so the slope of a line parallel to the given line is 2
plug in the given point and slope of 2 into point slope form
y+1 = 2 (x+4)
solve for slope intercept form
y+1 = 2x + 8
y = 2x + 7
answer: y=2x+7
