Given that,

Shelley's pet food store sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20.

For peanut, the cost is ratio is

\dfrac{5}{3}

For beef, the ratio is

\dfrac{7}{4.2}

If we take cross product of these items,

\dfrac{5}{3}=\dfrac{7}{4.2}\\\\5\times 4.2=3\times 7\\\\21=21

It implies, that the sale is in true proportion. From the cross product, we find that it is equal.

Here, as triangles are equal, their ratio would be equal.
8/x+4 = 12 /2x+1
8(2x+1) = 12(x+4)
16x+8 = 12x + 48
16x-12x = 48 - 8
4x = 40
x = 10

Hope this helps!

What is the measure of \angle x∠xangle, x?<br> Angles are not necessarily drawn to scale.
natita [175]

Answer:

74 degrees

Step-by-step explanation:

You can see this is a supplementary angle, which means that it is a straight line with a line sticking out. This means the two angles add up to 180 degrees, so 180 - 106 = 74, which is your answer.

Four students are competing in a race. In how many different combinations could the four students place in the race?
VMariaS [17]

"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.

If 4 students are competing, then the race has

4! = 4 • 3 • 2 • 1 = 24

possible outcomes.
