Answer:
Tues=8 Weds=24 Thurs=120
Step-by-step explanation:
The question can be modeled by the equation x+3x+15x=152
x is the amount sold on tuesday, 3x is 3 times the amount sold on tuesday so it represents wednesday and 15x represents thursday as it is 5 times the amount sold on wednesday.
Now we just need to solve for x to figure out how many he sold each day.
x+3x+15x=19x
19x=152
x=152/19
x=8
To find the amount sold on each day just mulitiply x by the coefficient
Tuesday = x = 8
Wednesday = 3x = 3*8 = 24
Thursday = 15x = 15*8 = 120
Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
Answer:
i guess the answer is 64x^5
Step-by-step explanation:
(4x^2)^3
=64x^5
<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
