Answer: 81
Step-by-step explanation: Divide the number of blue marbles by the number in the ratio of the number of blue marbles. 99/11=9. Then multiply that by 9 to get the number of red marbles. 9*9=81.
Answer:
This graph would start at (0, 2) and go straight through the point (2, 5).
Step-by-step explanation:
When graphing equations in slope-intercept form, always start at (0, ?) in which the ? is the constant at the end of the equation. In this case, that number would be 2.
Then when we have a fraction for a slope, we can add the top number to the y value and the bottom number to the x number.
(0, 2)
(0+2, 2+3)
(2, 5)
When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.
100 + 80 + 88 + 92 = 360
360 / 4 = 90
86 * 5 = 430
430 - 360 = 70
Answer = 70
100 + 80 + 88 + 92 + 70 = 430
430 / 5 = 86
