a. 60(h)+40=
b 60(3)+40=
180+40=$220
c. 400=60(h)+40=
360=60(h) *divide 60 on each side*
6=h, 6 hours
2 equations, 2 unknowns. Call height H and base B.
From the first sentence:
HB = 216
From the second sentence:
H = ⅔ B
Plug the second into the first and solve for B:
(⅔ B)B = 216
B^2 = 324
B = 18
Plug that back into either of the original 2 equations and solve for H:
H(18) = 216
H = 12
Answer:
Step-by-step explanation:
<u>Scale is:</u>
- 1 foot = 3/4 inch
- 1 inch = 1 : 3/4 foot = 4/3 foot
a. The length of the room
- 9 inches = 9*4/3 foot = 12 feet
b. The width of the room
- 6 3/4 inches = 27/4 inches = 27/4*4/3 = 9 feet
Do 37 divided by 9
That's the answer
