Write a real-world problem that could be represented by the expression 3(23). Then explain how you could solve the problem menta

Natalija [7]

3(23) really means 3*23, or just 3 multiplied by 23. For example: "Jana has 23 dollars. Her friend John has $23, and his friend Jacob also has 23 dollars. How much money do they have all together?" To solve this problem mentally, you could break 3*23 into two numbers you're familiar with multiplying, like 20 and 3, and then add the numbers together. For example: 3*20 + 3*3. 3*20=60, 3*3=9, and 60+9=69. So, 3*23=69.

Write the slope intercept form of the equation of the line passing through the point (5, -4) and perpendicular to the line y=-4/

n200080 [17]

Y = -4/3x + 5....the slope here is -4/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the original slope and change the sign. So we have -4/3....we flip it and it becomes - 3/4....we change the sign and it becomes 3/4. So the perpendicular line will have a slope of 3/4.

y = mx + b
slope(m) = 3/4
(5,-4)...x = 5 and y = -4
now we sub into the formula and find b, the y int
-4 = 3/4(5) + b
-4 = 15/4 + b
-4 - 15/4 = b
-16/4 - 15/4 = b
-31/4 = b
so ur perpendicular equation is : y = 3/4x + (-31/4) which is written as :
y = 3/4x - 13/4 <== ur answer

Salutations!

<span>A bag contains 56 marbles: 7 red, 8 green, 11 yellow, 17 brown, and 13 blue.

If a marble is chosen at random, what is the probability that the marble is green?

Probability means an occurrence of a chance

(Probability of getting green marble) = </span> $8/56$

Simplify tex]8/56[/tex]

The simplified answer would be $1/7$

Hope I helped (:

Have a great day!
