Alenkasestr [34]3 years ago
6 0

Answer:

A : 20x+21=30x-29

B : m<1 = 121   m<2 = 121

Step-by-step explanation:

Original equation

  • 20x+21=30x-29

Add +29 to both sides

  • 20x+50=30x

Subtract -20x

  • 50=10x

Divide by 10

  • 5 = x

Checking your work and doing substitution

20(5)+21

100+21

121

30(5)-29

150-29

121

Starting with 113+ (2x+5)=180, combine like terms and to get 118+2x=180.  Subtract 180-118, which gives you 62.  Then you have 2x=62.  Divide both sides by 2 to get a final answer of x=31.

Find the surface area of the cylinder. Round your answer to the nearest tenth. (Open attachment to see image of the cylinder).
Vaselesa [24]
Formula: SA = (2 × π(pie) × radius × height) + (2 × π(pie) × radius square.)
So the equation will be SA=( 2 × 3.14 × 2 × 4) + ( 2 × 3.14 × 2²)
Then, we will get                                     ↓                            ↓
                                           SA=      50.24               +         25.12
                                           <u>SA =                   75.36 in</u>
