$5.75

Let’s make it simple

Sara got 2 hotdogs which cost $1.50

1.50 x 2 = $3

1.50:

0 x 2 = 0
5 x 2 = 10

Place the 1 over the 1.

So it should look like this:
1
1.50
x 2
____
0 0

2 x 1 = 2 + 1 = 3

Now. Sarah got a large soda for $2.75.
We must to 2.75 + 3

Which is simple.

5.75. Do not add the three to any of the numbers BEHIND the decimal.

So the answer is $5.75

Sarah has three more than four times the money that Jessica has. Together they have $72. How

hoa [83]

Answer:

Jessica has $13,80 and Sarah has $58.20.

Step-by-step explanation:

Let j be the amount of money that Jessica has.

Let s be the amount of money that Sarah has.

s + j = 72

Since Sarah has 3 more than 4 times what Jessica has...

s = 4j + 3

So 4j + 3 + j = 72

5j = 69

j = 13.8

So Jessica has $13,80.

Therefore Sarah has $58.20.

bezimeni [28]

If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is μ<=80.

The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.

The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.

It always contains = , ≤ , ≥ signs.
The results will be examined using a one-tailed hypothesis test.

Hence, μ<=80

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Sidana [21]

Answer:

$-2p^2-11p-35$

Step-by-step explanation:

$-2(p+4)^2-3+5p$

First we square the parenthesis. Apply FOIL method to multiply

$(p+4)^2= (p+4)(p+4)= p^2 + 4p+4p+16= p^2+8p+16$

$-2(p^2+8p+16) -3+5p$

distribute -2 inside the parenthesis

$-2p^2-16p-32-3+5p$

Now combine like terms

$-2p^2-11p-35$

Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.

natulia [17]

Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.

(x + 1)

(2x + 1)

(x + 2)

(5x + 1)

<span>(5x – 2)

Solution :

By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
</span>(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= <span>5x^2 + 10x - 2x - 4
= </span>5x^2 + 8x - 4
