Problem 1 + 10x + 13 = 4

Mathematics
1 answer:
lutik1710 [3]3 years ago
6 0

Answer:

x = -1

Step-by-step explanation:

Equation: 1+10x+13=4

Step 1: Balance both parts of the equation.

1+10x+13=4

(10x)+(1+13)=4

10x+14=4

10x+14=4

Step 2: Reduce 14 from both parts of the equation.

10x+14-14=4-14

10x= -10

Step 3: Split both sides by 10, because \mathrn {10x = -10}.

\frac{10x}{10} = \frac{-10}{10}

10 / -10 = -1

Therefore, x = -1.

Use numbers 3 7 6 1 2 and write a expression that simplifies to 45
guapka [62]

By using the numbers 3 7 6 1 2, we can make the equation: 7×6 - 3×1 +3(2) that simplifies to 45.

Step-by-step explanation:

  • Simplification is the process if following the operation indicated by the symbols.
  • Simplification includes all the mathematical operations like: addition, subtraction, multiplication, division, bracket operation etc.  

Now we are given numbers as:

                                          3, 7, 6, 1, 2

arranging these numbers with suitable mathematical operation symbol, we get:

                                   = 7×6 - 3×1 +3(2)

                                    = 45

Hence our equation yields exactly 45.

A worker places tape around a rectangular shipping label that is 2 times longer than it is wide. How much tape does the worker n
valina [46]

Answer:

444 :) (angel number, haha)

Step-by-step explanation:

it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74

so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!
