Answer:

I think the first step is to group all the addition first and then you do the subtraction.

How too simplify the problem 50÷5+3×4÷2-1​
Bumek [7]

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

There are no parentheses or exponents in this expression, so to the next step (Multiplication/Division)  

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right.

In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

50÷5+3×4÷2-1​

50 ÷ 5 = 10

10 + 3 × 4 ÷ 2 - 1

3 × 4 = 12

10 + 12 ÷ 2 - 1

12 ÷ 2 = 6

10 + 6 - 1

Addition/Subtraction

10 + 6 - 1

10 + 6 = 16

16 - 1

15

katen-ka-za [31]

Answer:

<B = 107

Step-by-step explanation:

This two triangles are congruent by SSS

So angleB = angleD

We can find angle D by the sum of the angles of a triangle

A+C+D = 180

32+41+D = 180

73+D = 180

D =180-73

D =107

C = B = 107

Tom's backyard has an area of 25 square yards. What is its area in square inches? (1 yd = 36 in.)
Iteru [2.4K]

Hey there!!

The area given : 25 square yards

We will find the length of the square.

Square area = side²

side² = 25

side = √25

side = 5 yards.

Now convert this into inches

1 yard --> 36 inches

5 yards --> 180 inches

Area = 180²

Area = 32400 inches²

Hope my answer helps!!
