Answer:
Given the system of equation:
g +h = 9 ......[1]
8g + 7.5h = 71 ......[2]
We can write equation [1] as;
g = 9-h ......[3]
Now, substitute equation [3] in [2] we get;
Using distributive property i,e 
.
72 - 8h +7.5h = 71
Combine like terms:
72 - 0.5 h = 71
Subtract 72 to both sides of an equation:
72 - 0.5 h -72 = 71-72
Simplify:
- 0.5 h = -1
Divide both sides by -0.5 we get;
Simplify:
h = 2
Substitute the value of h =2 in equation [3] to solve for g;
g = 9 - 2 = 7
g = 7
Therefore, the solution for the given equation is :
g = 7 and h = 2
Step-by-step explanation:
210÷3×2=140 (140)CD
210-140=70 (70)left
70÷4×1=17.50 (17.50)food
70-17.50=52.50 (52.50)left
The restrictions are what the denominator can not be. The denominator cannot be zero. So if the denominator has x+1 in it. If you put -1 in place of x. You would get zero. -1 is a restriction
Answer:
Took the test, answer is C) 17(100)+17(40)+17(4)
Answer:
y=4
Step-by-step explanation:
its asking which one you can answer without any more context, in this case its y=4 because all the other ones evolving x lead to a rabbit hole and will take you in circles.
