Hi there! :) The answer to your question is 3. First you do parenthesis r=3.
3+7=10, then you do 10*2=20. That is how you solve the problem.

Hope I helped! :)

20 = 2(r + 7)
20/2 = r + 7
10 = r + 7
10 - 7 = r
3 = r
r = 3

The answer is: r = 3.

Given that 2x + 7 equals 27 and 3x + 1 equals 28 does 2x + 7 equals 3 x + 1

ICE Princess25 [194]

2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27

3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28

27 does not equal 28
so no

9. Use the distance formula to find the distance between the points (-4,-4) and (4,4).

Tanzania [10]

Answer:

Step-by-step explanation:

Distance formula = $(x_{1}-x_{2})+(y_{1}-y_{2})$

Depending on which point is A and Which point is B, the answer is one of the two.

However, there is no such thing as negative distance, so your answer is 16 points in a certain direction.

A single card is drawn from a standard 52 card deck.

Alexandra [31]

Answer:

1/52

Step-by-step explanation:

We are given that

Total number of cards=52

Number of cards of 4 of spade=1

We have to find the probability of choosing the "4 of spades".

We know that

Probability, P(E)= $\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}$

Using the formula

The probability of getting 4 of spade= $\frac{1}{52}$

Hence, the probability of choosing the "4 of spades"=1/52
