Answer:
x=13
Step-by-step explanation:
15x-15
15*13=195
195-15=180
Let Y = total cost of both schools.
The total cost would be ( number of credits at Westside x 98) + (number of credits at Pinewood x 115).
The total number of credits he is taking is 14.
If w is the number of credits at Westside, then for Westside you have 98w ( $98 times the number of credit hours)
The equation is now y = 98w + (number of credits at Pinewood x 115).
The number of credit hours at Pinewood would be the total credit hours 14 minus the credit hours at Westside w, so you have 14-w, which needs to be multiplied by the cost at Pinewood.
The equation is now y = 98w + 115(14-w)
This can be simplified using the distributive property to:
Y = 98w + 1610 - 115w
Y = -17w + 1610
Answer:
3 and 2
Step-by-step explanation:
3 x 2 = 6
3 + 2 = 5
4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
Answer:
8 green picks
Step-by-step explanation:
Since this problem is a ratio that also gives a total, setting up equivalent ratios in a table with the total would be a good way to find the answer. Since there is 1 orange pick for every 2 green picks and there are a total of 12 picks, we can set up the following:
Orange 1 2 3 4 5
Green 2 4 6 8 10
Total 3 6 9 12 15
You can see from the table, that when there are 12 total picks, 4 of them are orange and 8 of them are green.
