Answer:
34
Step-by-step explanation:
1.) 14 + 18 ÷ 2 × 3 - 7
2.) 18 ÷ 2 = 9
3.) 14 + 9 × 3 - 7
4.) 9 × 3 = 27
5.) 14 + 27 - 7
6.) 14 + 27 = 41
7.) 41 - 7 = 34
Answer:
y = x/2 + 5/2
Step-by-step explanation:
Plug in and Solve. First find the perpendicular slope to y = -2x -4. It is the negative reciprocal, so m = 1/2.
21=27+x
If you replace x with -6 then your answer will be 21!!
Step-by-step explanation:
the answer is b
The width of the pathway is 3m
Step-by-step explanation:
Let the width of the pathway be 'w'
The area will be 130 square meters
The dimensions of the garden is 10 x 7
Area = (10+w) (7+w)
130 = 70 + 17w + w^2
w^2 + 17w - 60 = 0
w^2 +20w - 3w - 60 = 0
w ( w + 20) - 3 ( w + 20) = 0
(w + 20) (w - 3) = 0
w = -20 ( or) w = 3
w is the width and cannot be negative.
So, w = 3 meters
The width of the pathway is 3m
