Answer:
The bridge is 80 feet long
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The engineer used the scale 3 inch = 40 feet
∴ The scale drawing is ⇒ 3 inche : 40 feet
∵ The drawing length of the bridge is 6 inches
→ By using the ratio method
→ inch : feet
→ 3 : 40
→ 6 : x
→ By using cross multiplication
∵ 3 × x = 6 × 40
∴ 3x = 240
→ Divide both sides by 3
∴ x = 80
∵ x represents the actual length of the bridge
∴ The bridge is 80 feet long
Answer:
x = 18
Step-by-step explanation:
x/6 - 7 = -4
Add 7 on both sides.
x/6 = -4 + 7
x/6 = 3
Multiply 6 on both sides.
x = 3 × 6
x = 18
Answer:
80%
Step-by-step explanation:
75% + 20% - 15% = 80%
The probability is 80%
-1285 + 750 = -535 porque el está pagando 750 el balance que le queda es -535
