Answer:
x = 12
Step-by-step explanation:
Segment lengths of each chord have the same product.
(x -2)(x +6) = 9×20
x² +4x -12 = 180
x² +4x +4 = 196 . . . . . add 16 (complete the square)
(x +2)² = 14²
x +2 = 14 . . . . . . . . . . . positive root is the only one useful
x = 12
Answer:
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces
Step-by-step explanation:
you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain
Dough = 6 ounces
Suase = 4 ounces
Dough + sauce = 6 + 4 = 10
Let x = total number of guests
Dough ingredients + sauce ingredients = 130
10x = 130
Divide both sides by 10
x = 130/10
= 13
x = 13
Number of guests = 13
Total ounces of dough = 6 ounces × 13 guests
= 78 ounces of dough
Total ounces of sauce = 4 ounces × 13 guests
= 52 ounces of sauce
Therefore,
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces
Answer:
y = -5 (x+2)
Step-by-step explanation:
We can use the point slope form of a line
y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope
y-0 = -5(x--2)
y = -5 (x+2)
Answer:
10
Step-by-step explanation:
First make the fractions the same value:
3 and 3/4s is equal to
15/4 which is 30/8s
So,
10 3/8s go into 30/8s
Two of the numbers were switched in a multiplication equation, so the answer would be commutative- multiplication.
