Answer:
2(y-7) = 3
Step-by-step explanation:
Twice means multiply by 2.
The difference of a number and 7 means subtract a number/variable and 7.
Is equal to 3 means = 3.
2(y-7) = 3
Hope that helps.
Let x be the amount of winter snow that accumulates in the spring soil. The equation that represents the situation from the given above is,
x / 12 = w
where w is the depth of water. Substituting the given values,
x / 12 = 6
The value of x from the equation is 72. Therefore, the amount of winter snow is 72 inches. The answer is letter C.
X=46
Explanation:
You just have to make 3x-28 and x+64 equal to each other and x would be 46.
m∠1=44
Explanation:
You just have to subtract the 46 that u solved earlier from 90 degree so it’s 44
First we define variables:
x = first card original value
y = second card original value
z = third card original value
We write the system of equations:
Andrew bought 3 baseball cards for $ 240:
x + y + z = 240
the first card (at its original value) along with the second card (at its original price) and got $ 320:
2x + y = 320
the first card (at its original value) card along with the third card (at its original price) would have only got him $ 280:
2x + z = 280
Solving the system we have:
x = 120
y = 80
z = 40
Answer:
The original prices for each of the 3 baseball cards is:
(120, 80, 40)
Answer:
40° or 40.03 degrees or 25 inches as nilla mentioned.
