Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this: Find the unknown value in the proportion: 2 : x = 3 : 9.
Now let's do it
2. 2 is not shown in the picture
3. 2 1/2 sugar/7 1/2 flour = x sugar/1 flour
cross multiply: 2 1/2/7 1/2 = x/1
7 1/2x = 1(2 1/2) ... 15/2x = 5/2 ... x=5/2×2/15= 1/3
answer: 1/3 cup sugar = 1 cup flour ... 1/3s:1f
5. 1 1/3p/3 1/3c = ₩p/1c
cross multiply: (1 1/3)/(3 1/3) = ₩/1
3 1/3₩= 1(1 1/3) ... 10/3₩=4/3 ... ₩=4/3×3/10
₩=4/10=2/5 qt papaya
2/5 qt papaya = 1 qt carrot ... 2/5p:1c
Answer:
x=62
Step-by-step explanation:
The sum of x ,28, and 90 is 180 since it forms a straight line
x+28+90 = 180
Combine like terms
x+118 =180
Subtract 118 from each side
x+118-118 =180-118
x= 62

Answer:
x = 3
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the equation of the axis of symmetry is
x = - 
y = x² - 6x + 
is in standard form
with a = 1 and b = - 6, hence
x = - 
= 3
equation of axis of symmetry is x = 3
