Answer:
238
Step-by-step explanation:
let the number of marbles Sam has be x, then
Jim has x + 92 ← 92 more than Sam
After swap of 18 marbles
Sam has x - 18 and sam has x + 92 + 18 = x + 110
Jim now has twice as many as Sam, that is
x + 110 = 2(x - 18)
x + 110 = 2x - 36 ( subtract x from both sides )
110 = x - 36 ( add 36 to both sides )
146 = x
At first Jim had 146 + 92 = 238 marbles
In mathematics an expression is basically symbols, used to represent the value, or you could say a finite combination.
Answer: 7
Step-by-step explanation: All you have to do is use absolute value when a number is closed in so you would say 63 divided by positive 9 = 7
Answer:
The original distance between Dallas and Houston is 240 miles.
Step-by-step explanation:
The scale on a map is 1 cm = 50 miles.
That means, 1 cm length in the drawing is equivalent to 50 miles original distance.
We have to find the actual distance between Dallas and Houston, which are 4.8 cm distant on the map.
So, 4.8 cm length in the drawing will be equivalent to (50 × 4.8) = 240 miles.
Therefore, the original distance between Dallas and Houston is 240 miles. (Answer)
