Answer:
A
Step-by-step explanation:
Given
x - 9 > 3 ( add 9 to both sides )
x > 12
13, 15 and 17 are all greater than 12
However, 11 is less than 12 and is not in the solution set → A
Hello! To solve for x means to isolate x:
y = x^2 + 7
y - 7 = x^2
sqrt(y - 7) = x
Answer:
x = sqrt(y - 7)
Hope this helps!
Answer:
a > 8
Step-by-step explanation:
Divide by the coefficient of the variable. Since it is negative, the direction of the comparison must be reversed.
(-4a)/(-4) > (-32)/(-4)
a > 8
Answer:
50 grams
Step-by-step explanation:
From the above question:
Chicken : Turkey
= 4:1
Sum Proportions = 4 + 1 = 5
We have to find the weight in grams of the entire pie
Let us represent the weight in grams of the entire pie = x.
The pie contains 200g of Chicken.
Hence:
4/5 × x = 200g
4x/5 = 200g
Cross Multiply
4x = 200g × 5
x = 200g × 5/4
x = 250g
The amount turkey that is in the pie is calculated as:
Total weight of pie - Amount of Chicken in the pie
= 250g - 200g
= 50 g
