Answer:
138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Step-by-step explanation:
We are given:
Grams of Sodium = 76 g
Grams of Sodium Chloride = 214 g
We need to find how many grams of chlorine required to produce 214 g of sodium chloride
The equation will be:
We can write: 76 (g) + x (g)=214 (g)
Solving and finding value of x
x =214-76
x=138 g
So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Answer:
A
Step-by-step explanation:
- 1/5 of 5x is -1 or just -x and -1/5 of 20 is -4. Then the other one is-1/4 of 4 is -x and -1/4 of -28 is 7. Now combine like terms so -x + -x is -2x and 7+ -4 or 7-4 is 3
Answer:
FALSE
Step-by-step explanation:
If p could equal 10, 20, 30 or 40 lets put each of them in the expression 7.4p<=74
1. 7.4 times 10 equals 74 so that work✅
2. 7.4 times 20 equals 148 so that does not work X
3. 7.4 times 30 equals 222 so that does not work X
4. 7.4 times 40 equals 296 so that does not work X
Answer:
-x + y = 8
Step-by-step explanation:
Slope =
=
slope = 1, m represents the slope
y - y1 = m(x - x1)
choose any point ( -1, 7 ) or ( 2,10 )
y - 7 = 1( x + 1 )
y - 7 = x + 1
-x + y = 8
