Answer:

Step-by-step explanation:

$19.50

-$15.50=

$4.00

1slice of pizza and 1soda is $4

so 2slices of pizza and 2 sodas is $8

$15.50-$8=$7.50

Now you have 3 slices of pizza left

$7.50/3slices=$2.50

1slice of pizza is $2.50

Answer:

each burger costs : $4.50

each slice of pizza costs : $2

Step-by-step explanation:

3 slices of pizza + 2 burgers = $15.50 ➡ 3p + 2b = $15.50

1 slice of pizza + 4 burgers = $20➡ 1p + 4b = $20

multiply second equation by -3 then add both equations up

-3p - 12b + 3p + 2b = $15.50 - $60 ➡-10b = -$44.50

b = $4.50 now use this value in the second equation to find the price of pizza slice

1p + 4×4.50 = $20 ➡1p = $2

Plz answer both questions 15 points

Answer:

If the signs of rational numbers are same, then the answer is positive.

If the signs of rational numbers are different, then the answer is negative.

Step-by-step explanation:

Consider the provided information.

A: When multiplying or dividing rational numbers, when will the answer be positive?

If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.

For example: Multiply 2 and 4.

2×4=8 (same sign)

Multiply -2 and -4.

-2×-4=8 (same sign)

8 is a positive rational number.

Now divided 2 and 4.

$\frac{2}{4} =\frac{1}{2}$

Divided -2 and -4.

$\frac{-2}{-4} =\frac{1}{2}$

1/2 is a positive rational number.

Hence, If the signs of rational numbers are same, then the answer is positive.

B: When multiplying or dividing rational numbers, when will the answer be negative?

If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.

For example: Multiply 2 and -4.

2×-4=-8 (different sign)

Multiply -2 and 4.

-2×4=-8 (different sign)

-8 is a negative rational number.

Now divided 2 and -4.

$\frac{2}{-4} =-\frac{1}{2}$

Divided -2 and 4.

$\frac{-2}{4} =-\frac{1}{2}$

-1/2 is a negative rational number

Hence, If the signs of rational numbers are different, then the answer is negative.

Solve for 'p'

Darina [25.2K]

$\left(\dfrac{9a^{-4}}{25}\right)^p=\dfrac3{5a^2}$
$\left(\dfrac9{25a^4}\right)^p=\dfrac3{5a^2}$

One way to find $p$ is to notice that the part on the left hand side within the parentheses can be written as a square:

$\dfrac9{25a^4}=\dfrac{3^2}{5^2(a^2)^2}=\left(\dfrac3{5a^2}\right)^2$

So you could write

$\left(\left(\dfrac3{5a^2}\right)^2\right)^p=\left(\dfrac3{5a^2}\right)^{2p}=\dfrac3{5a^2}$

Since these two expressions are equal, and the bases are the same, you know the exponents must be equal, with the exponent on the right hand side being 1. So $2p=1$ , or $p=\dfrac12$ .

Reptile [31]

at most is either that number or less

so x<=72 would be the inequality
