I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour

The sum of two numbers is 136 one number is 51 what is the other number? What are the common factors of these two numbers?
Rom4ik [11]
The sum of two numbers is 136 (sum is what you get when you add two numbers together). If one of the two numbers is 51, and the other number is X, then:

X + 51 = 136

To solve for x we subtract both sides by 51.

X + 51 -51 = 136 - 51
X = 85

The other number is 85.

What are the common factors of these two numbers?
Factors are the numbers that multiply to make the product.

Factors of 51: 1, 51, 3, 17
Factors of 85: 1, 85, 5, 17

210 is equal to the total of p and 111
Aleks [24]

Answer:

p + 111 = 210

p = 99

Step-by-step explanation:

Break the question down into parts.

<u>Convert each part into algebraic form</u> (numbers or symbols).

210                                =>   210

is equal to                    =>   =

the total of p and 111    =>   p + 111

Put the equation together:

210 = p + 111

Usually, the variable is on the left side:

p + 111 = 210

<u>To solve the equation is to isolate "p"</u>. This means to keep "p" on the left, and move everything else to the right side. When moving something, do the <u>reverse operation</u> to both sides of the equation.

p + 111 = 210            "111" should be on the left. It's opposite is -111.

p + 111 - 111 = 210 - 111                Simplify. "111" cancels out on the left.

p = 99                     Solved for "p"
