Answer:
B
Step-by-step explanation:
Our equation is x² + 7x - 4 = 0. We need to use the quadratic formula, which states that for a quadratic formula of the form ax² + bx + c = 0, then the zeroes/solutions are: or .
Here, a = 1, b = 7, and c = -4. Plug these in:
OR
Thus, the answer is B.
Answer:
There are 182.88 cm in 2 yards.
Step-by-step explanation:
Given that,
1 inch = 2.54 cm
We need to find how many centimeters are there in 2 yards.
We know that,
1 yard = 36 inch
⇒ 2 yards = (2×36) inches
= 72 inches
It means,
72 inches = (72 × 2.54) cm
= 182.88 cm
Hence, there are 182.88 cm in 2 yards.
Cancel -5y and 5x
leaving you with
8x=-18
2x=58
add
10x = 40
x= 4
substitute to find y
5y+2x=58
5y+8=58
5y=50
y=10
The equation illustrates inverse property of addition.
Explanation:
The equation is
The equation illustrates inverse property of addition.
The inverse property of addition states that the sum of a negative number and the same number which is positive will always be equal to zero.
Thus, the number added to its opposite sign results in zero.
In other words, the purpose of inverse property of addition is to get the result zero after addition.
Hence, the equation illustrates inverse property of addition.
Antonio have 3 dimes.
Step-by-step explanation:
Given,
Cost of snack = 45 cents
Worth of nickels = 15 cents
Worth of dime = x
Therefore,
Antonio has 30 cents worth of dimes.
10 cents = 1 dimes
