Answer:

yes

Step-by-step explanation:

you do that when you have a minus sign and a negative an example is like if you have 4-(-10)=? if you look at the part where its -(- it looks like a positive + so you add them so this is equal to 14, and when you are multiplying 2 negatives they both equal a positive an example is like -4 times -5 this equals 20, but if you have -5+-3=? this equals -8 because you are adding the numbers.

Hope this helps =)

brian and shawna are selling cookie dough. ryan sold 6 packod cookie dough and 12 packages of gingerbread cookies dough for a to

Bogdan [553]

Answer:

Chocolate chip dough = $12

Gingerbread cookie dough = $17

Step-by-step explanation:

Since there are two variables in this problem, setting up a system of equations and using the elimination method will help us find the cost for each package of cookie dough. Based on Ryan's sales of 6 packages of chocolate chip and 12 packages of gingerbread for $276, the first equation is:

6c + 12g = 276

Since Shawna sold 8 chocolate chip and 3 gingerbread for a total of $147.00, the second equation is:

8c + 3g = 147

Using the elimination method, we will need to multiply the second equation by a factor of -4 in order to eliminate the variable 'g':

-4(8c + 3g = 147) = -32c - 12g = -588

Add the two equations:

6c + 12g = 276

+ -32c - 12g = -588

-26c = -312 or c = $12

Plug the value of 'c' into the first equation:

6(12) + 12g = 276 or 72 + 12g = 276 or g = $17

Show that the triangles are similar by comparing the ratios of the corresponding sides. Simplify your answer completely in order

kirill [66]

Answer/Step-by-step explanation:

AC = 1.2

AB = 4

BC = 2.6

DF = 3

DE = 10

EF = 6.5

Thus:

$\frac{DE}{AB} = \frac{10}{4} = \frac{5}{2}$

$\frac{DF}{AC} = \frac{3}{1.2} = \frac{3*10}{1.2*10} = \frac{30}{12} = \frac{5}{2}$

$\frac{EF}{BC} = \frac{6.5}{2.6} = \frac{6.5*10}{2.6*10} = \frac{65}{26} = \frac{5}{2}$

The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.
