You combine the numbers that have the same letter attached to them. Then you add or subtract the bumbers from each other to. After that you make the numbers and the numbers with letters into one equation
Ex: 13+5r+7r= 13+12r
Step-by-step explanation:
2w+w=3w If theres a letter by itself it means theres a 1.
Answer: 1
Step-by-step explanation:
3(2)-2(1)
6-2=4
Answer:
<em>Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 </em>
Step-by-step explanation:
<em>~ Let us first formulate the equations, provided x ⇒ cost paid daily when using the motorcycle, and y ⇒ cost paid for each kilometer driven in the motorcycle ~</em>
8x + 650y = 445.5, and 12x + 920y = 655.6
<em>Now let us solve this equation through elimination, by multiplying the first equation by 3, and the second by -2:</em>
3 ( 8x + 650y = 445.5 ) ⇒ 24x + 1950y = 1336.5 ⇒ 110y = 25.3
+ -2 ( 12x + 920y = 655.6 ) + -24x - 1840y = - 1311.2 <em>y = 0.23</em>
<em>Now we can substitute this value of y into the first equation as to solve for x: </em>8x + 650 ( 0.23 ) = 445.5, 8x = 296, <em>x = 37</em>
<em>* Cost paid daily when using the motorcycle: $37,</em>
<em>Cost paid for each kilometer driven in the motorcycle: $ 0.23 *</em>
Answer:
x = 15, y = 4
Step-by-step explanation:
By Basic proportionality theorem, we have:
x/ 5 = 18/6
x = (18*5)/6
x = 90/6
x = 15
Again By Basic proportionality theorem, we have:
12/y = 18/6
y = (12*6)/18
y = 72/18
y = 4
Answer: The base area, diameter, and radius can be found out by discovering the volume and height. Substitute the values to the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable to find the diameter which is double the radius.
