Mathematics

quester [9]3 years ago
7 0

Answer:

x = 3

y = -5

Step-by-step explanation:

It would be very easy to eliminate y by adding the two equations,

   4x - 7y = 47

   <u>6x + 7y = -17</u>

   10x       = 30

      x = 3                     4(3) - 7y = 47

                                   12 - 7y = 47

                                       -7y = 35

                                          y = -5

Check:  See if the values work in the second equation

6(3) + 7(-5)

= 18 - 35

= -17             It looks like they work, so we know we have the correct values

Please help me I really need help

The problem statement is cut off, but it appears you have 6 rods of 10 cubes and 6 unit cubes that are colored red.

6·10 + 6 = 66 . . . . standard form number

In words, this number is ...

... sixty-six

_____

The digits in the thousandths and hundredths places are both zero in this number. They are exactly equal, or you could pick any number you like and say that one of them is that number times the other of them. 0 = 43×0, for example.

The place value of the 1/1000ths place is 1/10 times the place value of the 1/100ths place, so if you have the number 66.322, the 2 in the thousandths place has a value of 2/1000, which is 1/10 times the value of the 2 in the hundredths place, which is 2/100.

The sphere has surface are of 900π m².

Step-by-step explanation:

Given,

Diameter = d = 30m

Radius = \frac{d}{2} =\frac{30}{2} = 15m

Surface area of sphere = 4\pi\ r^2

Surface\ area = 4*\pi *(15)^2\\Surface\ area = 4*\pi * 225\\Surface\ area= 990\pi

The sphere has surface are of 900π m².
