Mathematics

tatyana61 [14]3 years ago
5 0

Answer:

x = 4

Step-by-step explanation:

x + 4(x+5) = 40 (Given)

x + 4x + 20 = 40 (Distribute the 4 into the x and 5)

5x + 20 = 40 (Add like terms)

5x = 20 (Subtract 20 on both sides)

x = 4 (Divide 5 on both sides)

A race car Travel 100 feet in five seconds at this rate of speed how many feet will the race car travel in a minute?
Dafna11 [192]

Convert minute to seconds (1 minute = 60 seconds), set up a proportion, cross multiply, and solve.

Proportion: \frac{100  ft}{5  sec} = \frac{x}{60  sec}

Cross multiply: 60 · 100 = 5 · x

Solve (divide both sides by 5): 1200 = x

Answer: 1200 ft

Margie says the set of numbers, 0.1, -1, -2 1/4, 3, are in order from least to greatest. What is her error?
ANEK [815]

Her error was that she thought 0.1 and 1/4 were negatives but they are still positive.

She also thought the larger the negative the greatest one. The smaller negative is the greatest because it's bellow 0.

To solve this you would first need to turn 1/4 into 0.25

It would start out with -2 cause that is the least. Then -1. Now its back to positive so the least to greatest would be normal.

So the real answer would be -2, -1, 0.1, 1/4
