There is snow on the ground outside.
We presume you want to find values of x that make this true.
Subtract the right side and factor:
Once you have factors whose product is zero, you can find the values of x that make those factors zero. A product can only be zero if one or more contributing factors is zero.
To solve 2x-5=0, you can add 5 then divide by 2:
... 2x -5 = 0
... 2x = 5
... x = 5/2
Answer:
B
Step-by-step explanation:
Both A and B are 2 units from the y- axis ( equidistant ) B is therefore A reflected across the y- axis with only their x- coordinates different signs.
Answer:
9:3
Step-by-step explanation:
Always keep your ratios in the same order with the same labels.
8+1=9
2+1=3
9:3
Answer:
We need to solve each equation:
1. 2x - 5 = x
2x - x = 5
x = 5 ✅
2. -3b + 1 = 3b -5
5 + 1 = 3b + 3b
6 = 6b
b = 1 ✅
3. (1/2)t + 7 = (3/2)t - 4
t + 14 = 3t - 8
2t = 22
t = 11 ✅
4. -2.3 + 1.2x = 5.9 - 2.9x
2.9x + 1.2x = 5.9 + 2.3
4.1x = 8.2
x = 2 ✅
5. -7y -21 = -3y - 21
-21 + 21 = -3y + 7y
0 = 4y
y = 0 ✅
