Answer:
a. (3-7x) + (3-7x) + (3-7x) + (3-7x)
b. 4(3-7x)
c. 12 - 28x
Step-by-step explanation:
To find the perimeter of a square, you need to add up all the sides
a. Since a square has all equal sides you will need to write the expression four times: (3-7x) + (3-7x) + (3-7x) + (3-7x) = perimeter
b. Expressing this as a product, we can condense the formula to 4 multiplied by the expression since it is written four times: 4(3-7x) = perimeter
c. Using the distributive property, we can write the product 4(3-7x) from b. as: (4)(3) + (4)(-7x) = 12 + (-28x) = 12 - 28x = perimeter
Answer:
That doesn't make sense, it's wrong. t=60 because 45+15=60
Step-by-step explanation:
It is 148 you have to add Everything up together
Answer:
adult tickets x=88 and senior tickets y=52
Step-by-step explanation:We can take adult ticket as x and senior ticket as y.
Now we will form two equations
x + y = 140
13x + 10y = 1664
This system of equations we will solve using Gaussian algorithm (gradual elimination of the variables)
We will multiply first equation with (-10) and get
-10x-10y=-1400 Than we will add to second equation and get
3x=264 => x=264/3=88 => x=88
Now we will replace x in the first equation before multiplying and get
88+ =140 => y= 140-88= 52 => y=52
adult tickets x=88 and senior tickets y=52
Good luck!!!
Are there any answers to choose from?
So if Jack was 10 years older than Priscilla and their ages combined equals to 170. I believe Priscilla is 80 and Jack was 90 cause 90+80=170
