Answer:

-9

Step-by-step explanation:

Use the order of operations. Do these operations in this order:

  • Parenthesis
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

Note: when either multiplication and division, or addition and subtraction are there, go left to right.

Equation: -1 - 2 · {(-1) + 5}

Solve:

  • -1 - 2 · {(-1) + 5}
  • -1 - 2 · {4}
  • -1 - 8
  • -9

*Challenge*

Using the same method, see if you can solve this equation:

6 ÷ 2(1+2)

Martiza remembers her pin because it is between 1000 and 1500 and it is a product of two consecutive prime numbers what is her p
Anna71 [15]

Answer:

Her pin must be 1147

Step-by-step explanation:

A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

\sqrt{1000}  = 31.6

\sqrt{1500} = 38.7

Since the only prime numbers in the range of 31 and 38 is 31 and 37.

We can then multiply 31 by 37 to get 1147.

Find the gradient of the line segment between the points (2,3) and (4,7)
belka [17]

Answer:

2.

Step-by-step explanation:

The gradient or slope of a straight line which is found between two points (x1, y1) and (x2, y2) is given by the formula:

m = (y2 - y1) / (x2 - x1)

Where y2 = 7

y1 = 3

x2 = 4

x1 = 2

=> m = (7 - 3) / (4 - 2)

m = 4 / 2 = 2

The gradient is 2.
