Answer:
Step-by-step explanation:
To try to solve these problems, you could plug 'n play. If all the blanks are addition, you/ll be > 24
If all the blanks are subtraction, it will be < 0
Multiplication doesn't work for all of them.
I did notice that 15 + 9 = 24, 5*6 = 30, and you get back to 15 if you subtract 15 after multiplying 5 and 6
Answer:
Step-by-step explanation:
Let x be the number of pants and y be the number of shirts
x + y = 6
20x + 15y = 100
multiply the first equation by -20
-20x -20y = -120
20x + 15y = 100
subtract the equations
-5y = -20
y = 4
replace y in equation 1
x + 4 = 6
x = 2
X=3. 33x-21x equals 12x. 24+12=36. 12x divided by 36 equals 3
Answer:
Option: 2 is correct.
( 2. Measuring the ingredients for concrete )
Step-by-step explanation:
<em>" As we know that Geometry is a branch of mathematics that deals with shape, size, line, angles and relative position.Also Architecture begins with geometry "</em>
1. checking the foundation of a building
4. The creating of a stained glass window ( since the design on the window may be any geometrical design)
3. To design a bridge (since in designing a bridge the angle is very essential i.e. at which angle the bridge will stand).
Hence, the correct option is:
2.Measuring the ingredients for concrete.
( since ingredients has nothing to do with geometry)
