25+{2[3+8-7(25/5)+11]}

Mathematics
1 answer:
Inessa05 [86]3 years ago

Let's solve it step by step:
(we start with the innermost bracket:  (25/5). This is equal to 5. :

25+{2[3+8-7(25/5)+11]} =
25+{2[3+8-7(5)+11]} =

now, we can multiply 7 and 5, which is 35

25+{2[3+8-35+11]} =

Now we can add all the numbers in the square bracket, 3,8 (that's 11), then -35 (which is -24) then 11 - all together it's -13
3+8-35+11=22-35=-13

25+{2[-13]} =

Multiplying 2 and -13
25+{-26} =25-26, which is -1

the final answer is -1

Problem Solving
KATRIN_1 [288]

by unitary method the exact answer is correct (2,920 glasses).

given, glasses of water each day = 8

therefore, by unitary method :

glasses of water in 365 day = 8*365 = 2920

hence the total glasses of water in 365 days = 2,920

Solve . 3/27 = w/54
WINSTONCH [101]

\frac{3}{27}=\frac{w}{54}    Multiply 54 to both sides to get "w" by itself

(54)\frac{3}{27}=\frac{w}{54}(54)

\frac{162}{27} =w

6 = w

Can someone help me.
Sauron [17]

Answer:

The answer to your question is: 20°

Step-by-step explanation:

Data

m∠XZY = 40

m∠XZB = 20

Process

1.- Find the measure of ∠ XAB

   ∠XAB = 40°   because AB ║ YZ

2.- Find the measure of ∠ZAB

     ∠ZAB + ∠XAB = 180

    ∠ZAB = 180 - ∠XAB

    ∠ZAB = 180 - 40

    ∠ZAB = 140°

3.- Find the measure of ∠ABZ

    The sum of the internal angles in a triangle equals 180°

     ∠AZB + ∠ZAB + ∠ABZ = 180

     20° + 140° + ∠ABZ = 180

     ∠ABZ = 180 - 20 - 140

    ∠ABZ = 20°

Need help on number 25 and 26 can you please explain how you got the answer thanks!:)
Westkost [7]
In both problems, the sum of side lengths is the perimeter. Opposite sides of a parallelogram (or rectangle) are equal in length, so you can find the perimeter by doubling the sum of adjacent sides.

25. 2(x +(x +15)) = (x +45) +(x +40) +(x +25)
.. 4x +30 = 3x +110 . . . . . . . . . . . . . . . . . . . . . . simplify
.. x = 80 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subtract 3x+30
.. 4x +30 = 4*80 +30 = 240
The perimeter of each is 240 units.

26. 2(x +(x +2)) = (x) +(x +6) +(x +4)
.. 4x +4 = 3x +10 . . . . . . . . . . . . . . . . . . . . . . simplify
.. x = 6 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . subtract 3x+4
.. 4x +4 = 4*6 +4 = 28
The perimeter of each is 28 units.
